+ });

+ ## Using Embedded Records
- DS.Store = Store;
- DS.PromiseArray = PromiseArray;
- DS.PromiseObject = PromiseObject;
+ `DS.EmbeddedRecordsMixin` supports serializing embedded records.
- DS.Model = Model;
- DS.RootState = RootState;
- DS.attr = attr;
- DS.Errors = Errors;
+ To set up embedded records, include the mixin when extending a serializer
+ then define and configure embedded (model) relationships.
- DS.AttributeChange = AttributeChange;
- DS.RelationshipChange = RelationshipChange;
- DS.RelationshipChangeAdd = RelationshipChangeAdd;
- DS.OneToManyChange = OneToManyChange;
- DS.ManyToNoneChange = OneToManyChange;
- DS.OneToOneChange = OneToOneChange;
- DS.ManyToManyChange = ManyToManyChange;
+ Below is an example of a per-type serializer ('post' type).
- DS.Adapter = Adapter;
- DS.InvalidError = InvalidError;
+ ```js
+ App.PostSerializer = DS.RESTSerializer.extend(DS.EmbeddedRecordsMixin, {
+ attrs: {
+ author: { embedded: 'always' },
+ comments: { serialize: 'ids' }
+ }
+ });
+ ```
+ Note that this use of `{ embedded: 'always' }` is unrelated to
+ the `{ embedded: 'always' }` that is defined as an option on `DS.attr` as part of
+ defining a model while working with the ActiveModelSerializer. Nevertheless,
+ using `{ embedded: 'always' }` as an option to DS.attr is not a valid way to setup
+ embedded records.
- DS.DebugAdapter = DebugAdapter;
+ The `attrs` option for a resource `{ embedded: 'always' }` is shorthand for:
- DS.RecordArray = RecordArray;
- DS.FilteredRecordArray = FilteredRecordArray;
- DS.AdapterPopulatedRecordArray = AdapterPopulatedRecordArray;
- DS.ManyArray = ManyArray;
+ ```js
+ {
+ serialize: 'records',
+ deserialize: 'records'
+ }
+ ```
- DS.RecordArrayManager = RecordArrayManager;
+ ### Configuring Attrs
- DS.RESTAdapter = RESTAdapter;
- DS.FixtureAdapter = FixtureAdapter;
+ A resource's `attrs` option may be set to use `ids`, `records` or false for the
+ `serialize` and `deserialize` settings.
- DS.RESTSerializer = RESTSerializer;
- DS.JSONSerializer = JSONSerializer;
+ The `attrs` property can be set on the ApplicationSerializer or a per-type
+ serializer.
- DS.Transform = Transform;
- DS.DateTransform = DateTransform;
- DS.StringTransform = StringTransform;
- DS.NumberTransform = NumberTransform;
- DS.BooleanTransform = BooleanTransform;
+ In the case where embedded JSON is expected while extracting a payload (reading)
+ the setting is `deserialize: 'records'`, there is no need to use `ids` when
+ extracting as that is the default behavior without this mixin if you are using
+ the vanilla EmbeddedRecordsMixin. Likewise, to embed JSON in the payload while
+ serializing `serialize: 'records'` is the setting to use. There is an option of
+ not embedding JSON in the serialized payload by using `serialize: 'ids'`. If you
+ do not want the relationship sent at all, you can use `serialize: false`.
- DS.ActiveModelAdapter = ActiveModelAdapter;
- DS.ActiveModelSerializer = ActiveModelSerializer;
- DS.EmbeddedRecordsMixin = EmbeddedRecordsMixin;
- DS.belongsTo = belongsTo;
- DS.hasMany = hasMany;
+ ### EmbeddedRecordsMixin defaults
+ If you do not overwrite `attrs` for a specific relationship, the `EmbeddedRecordsMixin`
+ will behave in the following way:
- DS.ContainerProxy = ContainerProxy;
+ BelongsTo: `{ serialize: 'id', deserialize: 'id' }`
+ HasMany: `{ serialize: false, deserialize: 'ids' }`
- DS._setupContainer = setupContainer;
+ ### Model Relationships
- Ember.lookup.DS = DS;
+ Embedded records must have a model defined to be extracted and serialized. Note that
+ when defining any relationships on your model such as `belongsTo` and `hasMany`, you
+ should not both specify `async:true` and also indicate through the serializer's
+ `attrs` attribute that the related model should be embedded. If a model is
+ declared embedded, then do not use `async:true`.

- You can use this method to normalize the JSON root keys returned
- into the model type expected by your store.
+ This method is used to convert each JSON root key in the payload
+ into a typeKey that it can use to look up the appropriate model for
+ that part of the payload. By default the typeKey for a model is its
+ name in camelCase, so if your JSON root key is 'fast-car' you would
+ use typeForRoot to convert it to 'fastCar' so that Ember Data finds
+ the `FastCar` model.
+
+ If you diverge from this norm you should also consider changes to
+ store._normalizeTypeKey as well.
+
+ For example, your server may return prefixed root keys like so:
+
+ ```js
+ {
+ "response-fast-car": {
+ "id": "1",
+ "name": "corvette"
+ }
+ }
+ ```
- For example, your server may return underscored root keys rather than
- the expected camelcased versions.
+ In order for Ember Data to know that the model corresponding to
+ the 'response-fast-car' hash is `FastCar` (typeKey: 'fastCar'),
+ you can override typeForRoot to convert 'response-fast-car' to
+ 'fastCar' like so:
```js
App.ApplicationSerializer = DS.RESTSerializer.extend({
typeForRoot: function(root) {
- var camelized = Ember.String.camelize(root);

Holds validation errors for a given record organized by attribute names.
+ Every DS.Model has an `errors` property that is an instance of
+ `DS.Errors`. This can be used to display validation error
+ messages returned from the server when a `record.save()` rejects.
+ This works automatically with `DS.ActiveModelAdapter`, but you
+ can implement [ajaxError](api/data/classes/DS.RESTAdapter.html#method_ajaxError)
+ in other adapters as well.
+
+ For Example, if you had an `User` model that looked like this:
+
+ ```javascript
+ App.User = DS.Model.extend({
+ username: attr('string'),
+ email: attr('string')
+ });
+ ```
+ And you attempted to save a record that did not validate on the backend.
+
+ ```javascript
+ var user = store.createRecord('user', {
+ username: 'tomster',
+ email: 'invalidEmail'
+ });
+ user.save();
+ ```
+
+ Your backend data store might return a response that looks like
+ this. This response will be used to populate the error object.
+
+ ```javascript
+ {
+ "errors": {
+ "username": ["This username is already taken!"],
+ "email": ["Doesn't look like a valid email."]
+ }
+ }
+ ```
+
+ Errors can be displayed to the user by accessing their property name
+ or using the `messages` property to get an array of all errors.
+
+ ```handlebars
+ {{#each errors.messages}}

+ ];
+ }
- ```
- valueBinding: "MyApp.someController.title"
- ```
+ return {
+ queue: this,
+ target: target,
+ method: method
+ };
+ },
- This will create a binding from `MyApp.someController.title` to the `value`
- property of your object instance automatically. Now the two values will be
- kept in sync.

+ var queue = this._queue, currentTarget, currentMethod, i, l;

+ if (guid) {
+ return this.pushUniqueWithGuid(guid, target, method, args, stack);
+ }
+ }
- One especially useful binding customization you can use is the `oneWay()`
- helper. This helper tells Ember that you are only interested in
- receiving changes on the object you are binding from. For example, if you
- are binding to a preference and you want to be notified if the preference
- has changed, but your object will not be changing the preference itself, you
- could do:
+ this.pushUniqueWithoutGuid(target, method, args, stack);
- ```
- bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
- ```
+ return {
+ queue: this,
+ target: target,
+ method: method
+ };
+ },
- This way if the value of `MyApp.preferencesController.bigTitles` changes the
- `bigTitles` property of your object will change also. However, if you
- change the value of your `bigTitles` property, it will not update the
- `preferencesController`.

+ var target, method, args, stack, i, l = queue.length;
- One way bindings are almost twice as fast to setup and twice as fast to
- execute because the binding only has to worry about changes to one side.
+ this.targetQueues = Object.create(null);
- You should consider using one way bindings anytime you have an object that
- may be created frequently and you do not intend to change a property; only
- to monitor it for changes (such as in the example above).

+ if (l && after) { after(); }
- All of the examples above show you how to configure a custom binding, but the
- result of these customizations will be a binding template, not a fully active
- Binding instance. The binding will actually become active only when you
- instantiate the object the binding belongs to. It is useful however, to
- understand what actually happens when the binding is activated.
+ // check if new items have been added
+ if (queue.length > l) {
+ this._queue = queue.slice(l);
+ this.flush();
+ } else {
+ this._queue.length = 0;
+ }
+ },
- For a binding to function it must have at least a `from` property and a `to`
- property. The `from` property path points to the object/key that you want to
- bind from while the `to` path points to the object/key you want to bind to.
+ cancel: function(actionToCancel) {
+ var queue = this._queue, currentTarget, currentMethod, i, l;
+ var target = actionToCancel.target;
+ var method = actionToCancel.method;
+ var GUID_KEY = this.globalOptions.GUID_KEY;
- When you define a custom binding, you are usually describing the property
- you want to bind from (such as `MyApp.someController.value` in the examples
- above). When your object is created, it will automatically assign the value
- you want to bind `to` based on the name of your binding key. In the
- examples above, during init, Ember objects will effectively call
- something like this on your binding:
+ if (GUID_KEY && this.targetQueues && target) {
+ var targetQueue = this.targetQueues[target[GUID_KEY]];
- ```javascript
- binding = Ember.Binding.from(this.valueBinding).to("value");
- ```
+ if (targetQueue) {
+ for (i = 0, l = targetQueue.length; i < l; i++) {
+ if (targetQueue[i] === method) {
+ targetQueue.splice(i, 1);
+ }
+ }
+ }
+ }
- This creates a new binding instance based on the template you provide, and
- sets the to path to the `value` property of the new object. Now that the
- binding is fully configured with a `from` and a `to`, it simply needs to be
- connected to become active. This is done through the `connect()` method:
+ for (i = 0, l = queue.length; i < l; i += 4) {
+ currentTarget = queue[i];
+ currentMethod = queue[i+1];
- ```javascript
- binding.connect(this);
- ```
+ if (currentTarget === target &&
+ currentMethod === method) {
+ queue.splice(i, 4);
+ return true;
+ }
+ }
- Note that when you connect a binding you pass the object you want it to be
- connected to. This object will be used as the root for both the from and
- to side of the binding when inspecting relative paths. This allows the
- binding to be automatically inherited by subclassed objects as well.
+ // if not found in current queue
+ // could be in the queue that is being flushed
+ queue = this._queueBeingFlushed;
+ if (!queue) {
+ return;
+ }
+ for (i = 0, l = queue.length; i < l; i += 4) {
+ currentTarget = queue[i];
+ currentMethod = queue[i+1];
- Now that the binding is connected, it will observe both the from and to side
- and relay changes.
+ if (currentTarget === target &&
+ currentMethod === method) {
+ // don't mess with array during flush
+ // just nullify the method
+ queue[i+1] = null;
+ return true;
+ }
+ }
+ }
+ };
- If you ever needed to do so (you almost never will, but it is useful to
- understand this anyway), you could manually create an active binding by
- using the `Ember.bind()` helper method. (This is the same method used by
- to setup your bindings on objects):
+ __exports__["default"] = Queue;
+ });

+ function each(collection, callback) {
+ for (var i = 0; i < collection.length; i++) {
+ callback(collection[i]);
+ }
+ }
- Both of these code fragments have the same effect as doing the most friendly
- form of binding creation like so:
+ __exports__.each = each;// Date.now is not available in browsers < IE9
+ // https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/now#Compatibility

- /**

- from a list of dependent properties.

- Example
+ Because `Ember.Application` inherits from `Ember.Namespace`, any classes
+ you create will have useful string representations when calling `toString()`.
+ See the `Ember.Namespace` documentation for more information.
- ```javascript
- var Hamster = Ember.Object.extend({
- hasClothes: Ember.computed.any('hat', 'shirt')

+ While you can think of your `Ember.Application` as a container that holds the

- var hamster = Hamster.create();
+ ### Event Delegation
- hamster.get('hasClothes'); // null
- hamster.set('shirt', 'Hawaiian Shirt');
- hamster.get('hasClothes'); // 'Hawaiian Shirt'
- ```
+ Ember uses a technique called _event delegation_. This allows the framework
+ to set up a global, shared event listener instead of requiring each view to
+ do it manually. For example, instead of each view registering its own
+ `mousedown` listener on its associated element, Ember sets up a `mousedown`
+ listener on the `body`.
- @method computed.any
- @for Ember
- @param {String} dependentKey*
- @return {Ember.ComputedProperty} computed property which returns
- the first truthy value of given list of properties.
- */

- for (var key in properties) {
- if (properties.hasOwnProperty(key) && properties[key]) {
- return properties[key];
- }
- }
- return null;
- });
+ If a `mousedown` event occurs, Ember will look at the target of the event and
+ start walking up the DOM node tree, finding corresponding views and invoking
+ their `mouseDown` method as it goes.
- /**
- A computed property that returns the array of values
- for the provided dependent properties.
+ `Ember.Application` has a number of default events that it listens for, as
+ well as a mapping from lowercase events to camel-cased view method names. For
+ example, the `keypress` event causes the `keyPress` method on the view to be
+ called, the `dblclick` event causes `doubleClick` to be called, and so on.
- Example
+ If there is a bubbling browser event that Ember does not listen for by
+ default, you can specify custom events and their corresponding view method
+ names by setting the application's `customEvents` property:
```javascript
- var Hamster = Ember.Object.extend({
- clothes: Ember.computed.collect('hat', 'shirt')
+ App = Ember.Application.create({
+ customEvents: {
+ // add support for the paste event
+ paste: "paste"
+ }
});
-
- var hamster = Hamster.create();
-
- hamster.get('clothes'); // [null, null]
- hamster.set('hat', 'Camp Hat');
- hamster.set('shirt', 'Camp Shirt');
- hamster.get('clothes'); // ['Camp Hat', 'Camp Shirt']
```
- @method computed.collect
- @for Ember
- @param {String} dependentKey*
- @return {Ember.ComputedProperty} computed property which maps
- values of all passed properties in to an array.
- */
- registerComputedWithProperties('collect', function(properties) {
- var res = [];
- for (var key in properties) {
- if (properties.hasOwnProperty(key)) {
- if (isNone(properties[key])) {
- res.push(null);
- } else {
- res.push(properties[key]);
- }
- }
- }
- return res;
- });
+ By default, the application sets up these event listeners on the document
+ body. However, in cases where you are embedding an Ember application inside
+ an existing page, you may want it to set up the listeners on an element
+ inside the body.
- /**
- Creates a new property that is an alias for another property
- on an object. Calls to `get` or `set` this property behave as
- though they were called on the original property.
+ For example, if only events inside a DOM element with the ID of `ember-app`
+ should be delegated, set your application's `rootElement` property:
```javascript
- Person = Ember.Object.extend({
- name: 'Alex Matchneer',
- nomen: Ember.computed.alias('name')
+ window.App = Ember.Application.create({
+ rootElement: '#ember-app'
});
+ ```
- alex = Person.create();
+ The `rootElement` can be either a DOM element or a jQuery-compatible selector
+ string. Note that *views appended to the DOM outside the root element will
+ not receive events.* If you specify a custom root element, make sure you only
+ append views inside it!
- alex.get('nomen'); // 'Alex Matchneer'
- alex.get('name'); // 'Alex Matchneer'
+ To learn more about the advantages of event delegation and the Ember view
+ layer, and a list of the event listeners that are setup by default, visit the
+ [Ember View Layer guide](http://emberjs.com/guides/understanding-ember/the-view-layer/#toc_event-delegation).
- alex.set('nomen', '@machty');
- alex.get('name'); // '@machty'
- ```
+ ### Initializers
- @method computed.alias
- @for Ember
- @param {String} dependentKey
- @return {Ember.ComputedProperty} computed property which creates an
- alias to the original value for property.
- */
- computed.alias = function(dependentKey) {
- return computed(dependentKey, function(key, value) {
- if (arguments.length > 1) {
- set(this, dependentKey, value);
- return value;
- } else {
- return get(this, dependentKey);
+ Libraries on top of Ember can add initializers, like so:
+
+ ```javascript
+ Ember.Application.initializer({
+ name: 'api-adapter',
+
+ initialize: function(container, application) {
+ application.register('api-adapter:main', ApiAdapter);
}
});
- };
+ ```
- /**
- Where `computed.alias` aliases `get` and `set`, and allows for bidirectional
- data flow, `computed.oneWay` only provides an aliased `get`. The `set` will
- not mutate the upstream property, rather causes the current property to
- become the value set. This causes the downstream property to permanently
- diverge from the upstream property.
+ Initializers provide an opportunity to access the container, which
+ organizes the different components of an Ember application. Additionally
+ they provide a chance to access the instantiated application. Beyond
+ being used for libraries, initializers are also a great way to organize
+ dependency injection or setup in your own application.

+ In addition to creating your application's router, `Ember.Application` is
+ also responsible for telling the router when to start routing. Transitions
+ between routes can be logged with the `LOG_TRANSITIONS` flag, and more
+ detailed intra-transition logging can be logged with
+ the `LOG_TRANSITIONS_INTERNAL` flag:
```javascript
- var User = Ember.Object.extend({
- firstName: null,
- lastName: null,
- nickName: Ember.computed.oneWay('firstName')
+ window.App = Ember.Application.create({
+ LOG_TRANSITIONS: true, // basic logging of successful transitions
+ LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps
});
+ ```
- var teddy = User.create({
- firstName: 'Teddy',
- lastName: 'Zeenny'
- });
+ By default, the router will begin trying to translate the current URL into
+ application state once the browser emits the `DOMContentReady` event. If you
+ need to defer routing, you can call the application's `deferReadiness()`
+ method. Once routing can begin, call the `advanceReadiness()` method.
- teddy.get('nickName'); // 'Teddy'
- teddy.set('nickName', 'TeddyBear'); // 'TeddyBear'
- teddy.get('firstName'); // 'Teddy'
+ If there is any setup required before routing begins, you can implement a
+ `ready()` method on your app that will be invoked immediately before routing
+ begins.
```

- The purpose of the Ember Instrumentation module is

- ```javascript
- Ember.subscribe("render", {
- before: function(name, timestamp, payload) {
+ * templates are looked up on `Ember.TEMPLATES`
+ * other names are looked up on the application after classifying the name.
+ For example, `controller:post` looks up `App.PostController` by default.
+ * if the default lookup fails, look for registered classes on the container
- },
+ This allows the application to register default injections in the container
+ that could be overridden by the normal naming convention.
- after: function(name, timestamp, payload) {
+ @private
+ @method resolverFor
+ @param {Ember.Namespace} namespace the namespace to look for classes
+ @return {*} the resolved value for a given lookup
+ */

+ var resolver = ResolverClass.create({
+ namespace: namespace
});
- ```
- If you return a value from the `before` callback, that same
- value will be passed as a fourth parameter to the `after`
- callback.
+ function resolve(fullName) {
+ return resolver.resolve(fullName);
+ }
- Instrument a block of code by using `Ember.instrument`:
+ resolve.describe = function(fullName) {
+ return resolver.lookupDescription(fullName);
+ };
- ```javascript
- Ember.instrument("render.handlebars", payload, function() {
- // rendering logic
- }, binding);
- ```
+ resolve.makeToString = function(factory, fullName) {
+ return resolver.makeToString(factory, fullName);
+ };
- Event names passed to `Ember.instrument` are namespaced

+ In this case, when the `name` property of the template's context changes,
+ the rendered value of the helper will update to reflect this change.
+
+ For more examples of bound helpers, see documentation for
+ `Ember.Handlebars.registerBoundHelper`.
+
+ ## Custom view helper example
+
+ Assuming a view subclass named `App.CalendarView` were defined, a helper
+ for rendering instances of this view could be registered as follows:
+
+ ```javascript
+ Ember.Handlebars.helper('calendar', App.CalendarView):
+ ```
+
+ The above bound helper can be used inside of templates as follows:
+
+ ```handlebars
+ {{calendar}}
+ ```
+
+ Which is functionally equivalent to:
+
+ ```handlebars
+ {{view 'calendar'}}
+ ```
+
+ Options in the helper will be passed to the view in exactly the same
+ manner as with the `view` helper.

- The `Ember.Mixin` class allows you to create mixins, whose properties can be
- added to other classes. For instance,
+ Would result in the following HTML:
+
+ ```html
+ <textarea class="ember-text-area">
+ Lots of text that IS bound
+ </textarea>
+ ```
+
+ If you wanted a one way binding between the text area and a div tag
+ somewhere else on your screen, you could use `Ember.computed.oneWay`:
```javascript
- App.Editable = Ember.Mixin.create({
- edit: function() {
- console.log('starting to edit');
- this.set('isEditing', true);
- },
- isEditing: false
+ App.ApplicationController = Ember.Controller.extend({
+ writtenWords: "Lots of text that IS bound",
+ outputWrittenWords: Ember.computed.oneWay("writtenWords")
});
+ ```
- // Mix mixins into classes by passing them as the first arguments to
- // .extend.
- App.CommentView = Ember.View.extend(App.Editable, {
- template: Ember.Handlebars.compile('{{#if view.isEditing}}...{{else}}...{{/if}}')
- });
+ ```handlebars
+ {{textarea value=writtenWords}}
- commentView = App.CommentView.create();
- commentView.edit(); // outputs 'starting to edit'
+ <div>
+ {{outputWrittenWords}}
+ </div>
```
- Note that Mixins are created with `Ember.Mixin.create`, not
- `Ember.Mixin.extend`.
+ Would result in the following HTML:
- Note that mixins extend a constructor's prototype so arrays and object literals
- defined as properties will be shared amongst objects that implement the mixin.
- If you want to define a property in a mixin that is not shared, you can define
- it either as a computed property or have it be created on initialization of the object.
+ ```html
+ <textarea class="ember-text-area">
+ Lots of text that IS bound
+ </textarea>
- ```javascript
- //filters array will be shared amongst any object implementing mixin
- App.Filterable = Ember.Mixin.create({
- filters: Ember.A()
- });
+ <-- the following div will be updated in real time as you type -->
- //filters will be a separate array for every object implementing the mixin
- App.Filterable = Ember.Mixin.create({
- filters: Ember.computed(function(){return Ember.A();})
- });
+ <div>
+ Lots of text that IS bound
+ </div>
+ ```
- //filters will be created as a separate array during the object's initialization
- App.Filterable = Ember.Mixin.create({
- init: function() {
- this._super();
- this.set("filters", Ember.A());
- }
+ Finally, this example really shows the power and ease of Ember when two
+ properties are bound to eachother via `Ember.computed.alias`. Type into
+ either text area box and they'll both stay in sync. Note that
+ `Ember.computed.alias` costs more in terms of performance, so only use it when
+ your really binding in both directions:
+
+ ```javascript
+ App.ApplicationController = Ember.Controller.extend({
+ writtenWords: "Lots of text that IS bound",
+ twoWayWrittenWords: Ember.computed.alias("writtenWords")
});

/**
- Provides a useful utility for when integrating with non-Ember libraries
- that provide asynchronous callbacks.
+ handlebarsGetView resolves a view based on strings passed into a template.
+ For example:
- Ember utilizes a run-loop to batch and coalesce changes. This works by
- marking the start and end of Ember-related Javascript execution.
+ ```handlebars
+ {{view "some-view"}}
+ {{view view.someView}}
+ {{view App.SomeView}} {{! deprecated }}
+ ```
- When using events such as a View's click handler, Ember wraps the event
- handler in a run-loop, but when integrating with non-Ember libraries this
- can be tedious.
+ A value is first checked to be a string- non-strings are presumed to be
+ an object and returned. This handles the "access a view on a context"
+ case (line 2 in the above examples).
- For example, the following is rather verbose but is the correct way to combine
- third-party events and Ember code.
+ Next a string is normalized, then called on the context with `get`. If
+ there is still no value, a GlobalPath will be fetched from the global
+ context (raising a deprecation) and a localPath will be passed to the
+ container to be looked up.

+ Register a bound handlebars helper. Bound helpers behave similarly to regular

- run.scheduleOnce('afterRender', myContext, sayHi);

- // sayHi will only be executed once, in the afterRender queue of the RunLoop
+ Ember.Handlebars.registerBoundHelper('capitalize', function(value) {
+ return Ember.String.capitalize(value);
});
```
- Also note that passing an anonymous function to `run.scheduleOnce` will
- not prevent additional calls with an identical anonymous function from
- scheduling the items multiple times, e.g.:
+ The above bound helper can be used inside of templates as follows:
- ```javascript
- function scheduleIt() {
- run.scheduleOnce('actions', myContext, function() { console.log("Closure"); });
- }
- scheduleIt();
- scheduleIt();
- // "Closure" will print twice, even though we're using `run.scheduleOnce`,
- // because the function we pass to it is anonymous and won't match the
- // previously scheduled operation.
+ ```handlebars
+ {{capitalize name}}
```
- Available queues, and their order, can be found at `run.queues`
+ In this case, when the `name` property of the template's context changes,
+ the rendered value of the helper will update to reflect this change.
- @method scheduleOnce
- @param {String} [queue] The name of the queue to schedule against. Default queues are 'sync' and 'actions'.
- @param {Object} [target] The target of the method to invoke.
- @param {Function|String} method The method to invoke.
- If you pass a string it will be resolved on the
- target at the time the method is invoked.
- @param {Object} [args*] Optional arguments to pass to the timeout.
- @return {Object} Timer information for use in cancelling, see `run.cancel`.
- */
- run.scheduleOnce = function(queue, target, method) {
- checkAutoRun();
- return apply(backburner, backburner.scheduleOnce, arguments);
- };
+ ## Example with options
- /**
- Schedules an item to run from within a separate run loop, after
- control has been returned to the system. This is equivalent to calling
- `run.later` with a wait time of 1ms.
+ Like normal handlebars helpers, bound helpers have access to the options
+ passed into the helper call.
```javascript
- run.next(myContext, function() {
- // code to be executed in the next run loop,
- // which will be scheduled after the current one
+ Ember.Handlebars.registerBoundHelper('repeat', function(value, options) {
+ var count = options.hash.count;
+ var a = [];
+ while(a.length < count) {
+ a.push(value);
+ }
+ return a.join('');
});
```
- Multiple operations scheduled with `run.next` will coalesce
- into the same later run loop, along with any other operations
- scheduled by `run.later` that expire right around the same
- time that `run.next` operations will fire.
-
- Note that there are often alternatives to using `run.next`.
- For instance, if you'd like to schedule an operation to happen
- after all DOM element operations have completed within the current
- run loop, you can make use of the `afterRender` run loop queue (added
- by the `ember-views` package, along with the preceding `render` queue
- where all the DOM element operations happen). Example:
+ This helper could be used in a template as follows:
- ```javascript
- App.MyCollectionView = Ember.CollectionView.extend({
- didInsertElement: function() {
- run.scheduleOnce('afterRender', this, 'processChildElements');
- },
- processChildElements: function() {
- // ... do something with collectionView's child view
- // elements after they've finished rendering, which
- // can't be done within the CollectionView's
- // `didInsertElement` hook because that gets run
- // before the child elements have been added to the DOM.
- }
- });
+ ```handlebars
+ {{repeat text count=3}}
```
- One benefit of the above approach compared to using `run.next` is
- that you will be able to perform DOM/CSS operations before unprocessed
- elements are rendered to the screen, which may prevent flickering or
- other artifacts caused by delaying processing until after rendering.
+ ## Example with bound options
- The other major benefit to the above approach is that `run.next`
- introduces an element of non-determinism, which can make things much
- harder to test, due to its reliance on `setTimeout`; it's much harder
- to guarantee the order of scheduled operations when they are scheduled
- outside of the current run loop, i.e. with `run.next`.
+ Bound hash options are also supported. Example:
- @method next
- @param {Object} [target] target of method to invoke
- @param {Function|String} method The method to invoke.
- If you pass a string it will be resolved on the
- target at the time the method is invoked.
- @param {Object} [args*] Optional arguments to pass to the timeout.
- @return {Object} Timer information for use in cancelling, see `run.cancel`.
- */
- run.next = function() {
- var args = slice.call(arguments);
- args.push(1);
- return apply(backburner, backburner.later, args);
- };
+ ```handlebars
+ {{repeat text count=numRepeats}}
+ ```
- /**
- Cancels a scheduled item. Must be a value returned by `run.later()`,
- `run.once()`, `run.next()`, `run.debounce()`, or
- `run.throttle()`.
+ In this example, count will be bound to the value of
+ the `numRepeats` property on the context. If that property
+ changes, the helper will be re-rendered.
+
+ ## Example with extra dependencies
+
+ The `Ember.Handlebars.registerBoundHelper` method takes a variable length
+ third parameter which indicates extra dependencies on the passed in value.
+ This allows the handlebars helper to update when these dependencies change.
```javascript
- var runNext = run.next(myContext, function() {
- // will not be executed
- });
- run.cancel(runNext);
+ Ember.Handlebars.registerBoundHelper('capitalizeName', function(value) {
+ return value.get('name').toUpperCase();
+ }, 'name');
+ ```
- var runLater = run.later(myContext, function() {
- // will not be executed
- }, 500);
- run.cancel(runLater);
+ ## Example with multiple bound properties
- var runOnce = run.once(myContext, function() {
- // will not be executed
+ `Ember.Handlebars.registerBoundHelper` supports binding to
+ multiple properties, e.g.:
+
+ ```javascript
+ Ember.Handlebars.registerBoundHelper('concatenate', function() {
+ var values = Array.prototype.slice.call(arguments, 0, -1);
+ return values.join('||');
});
- run.cancel(runOnce);
+ ```
- var throttle = run.throttle(myContext, function() {
- // will not be executed
- }, 1, false);
- run.cancel(throttle);
+ Which allows for template syntax such as `{{concatenate prop1 prop2}}` or
+ `{{concatenate prop1 prop2 prop3}}`. If any of the properties change,
+ the helper will re-render. Note that dependency keys cannot be
+ using in conjunction with multi-property helpers, since it is ambiguous
+ which property the dependent keys would belong to.
- var debounce = run.debounce(myContext, function() {
- // will not be executed
- }, 1);
- run.cancel(debounce);
+ ## Use with unbound helper
- var debounceImmediate = run.debounce(myContext, function() {
- // will be executed since we passed in true (immediate)
- }, 100, true);
- // the 100ms delay until this method can be called again will be cancelled
- run.cancel(debounceImmediate);
+ The `{{unbound}}` helper can be used with bound helper invocations
+ to render them in their unbound form, e.g.
+
+ ```handlebars
+ {{unbound capitalize name}}
```
- @method cancel
- @param {Object} timer Timer object to cancel
- @return {Boolean} true if cancelled or false/undefined if it wasn't found
- */
- run.cancel = function(timer) {
- return backburner.cancel(timer);
- };
+ In this example, if the name property changes, the helper
+ will not re-render.
- /**
- Delay calling the target method until the debounce period has elapsed
- with no additional debounce calls. If `debounce` is called again before
- the specified time has elapsed, the timer is reset and the entire period
- must pass again before the target method is called.
+ ## Use with blocks not supported
- This method should be used when an event may be called multiple times
- but the action should only be called once when the event is done firing.
- A common example is for scroll events where you only want updates to
- happen once scrolling has ceased.
+ Bound helpers do not support use with Handlebars blocks or
+ the addition of child views of any kind.
- ```javascript
- var myFunc = function() { console.log(this.name + ' ran.'); };
- var myContext = {name: 'debounce'};
+ @method registerBoundHelper
+ @for Ember.Handlebars
+ @param {String} name
+ @param {Function} function
+ @param {String} dependentKeys*
+ */
+ function registerBoundHelper(name, fn) {
+ var boundHelperArgs = slice.call(arguments, 1);
+ var boundFn = makeBoundHelper.apply(this, boundHelperArgs);
+ EmberHandlebars.registerHelper(name, boundFn);
+ }
- run.debounce(myContext, myFunc, 150);
+ __exports__.registerBoundHelper = registerBoundHelper;/**
+ A helper function used by `registerBoundHelper`. Takes the
+ provided Handlebars helper function fn and returns it in wrapped
+ bound helper form.
- // less than 150ms passes
+ The main use case for using this outside of `registerBoundHelper`
+ is for registering helpers on the container:
- run.debounce(myContext, myFunc, 150);
+ ```js
+ var boundHelperFn = Ember.Handlebars.makeBoundHelper(function(word) {
+ return word.toUpperCase();
+ });
- // 150ms passes
- // myFunc is invoked with context myContext
- // console logs 'debounce ran.' one time.
+ container.register('helper:my-bound-helper', boundHelperFn);

- Immediate allows you to run the function immediately, but debounce
- other calls for this function until the wait time has elapsed. If
- `debounce` is called again before the specified time has elapsed,
- the timer is reset and the entire period must pass again before
- the method can be called again.
+ In the above example, if the helper function hadn't been wrapped in
+ `makeBoundHelper`, the registered helper would be unbound.

- /**
- Checks to see if the `methodName` exists on the `obj`,
- and if it does, invokes it with the arguments passed.
+ This operator aliases the scope to a new name. It's helpful for semantic clarity and to retain
+ default scope or to reference from another `{{with}}` block.
- ```javascript
- var d = new Date('03/15/2013');
- Ember.tryInvoke(d, 'getTime'); // 1363320000000
- Ember.tryInvoke(d, 'setFullYear', [2014]); // 1394856000000

+ NOTE: The alias should not reuse a name from the bound property path.

+ ### `controller` option
- /**
- Provides try { } finally { } functionality, while working

+ Adding `controller='something'` instructs the `{{with}}` helper to create and use an instance of
+ the specified controller with the new context as its content.
- ```javascript
- var tryable = function() {
- someResource.lock();
- runCallback(); // May throw error.
- };
- var finalizer = function() {
- someResource.unlock();
- };
- Ember.tryFinally(tryable, finalizer);
+ This is very similar to using an `itemController` option with the `{{each}}` helper.
+
+ ```handlebars
+ {{#with users.posts controller='userBlogPosts'}}
+ {{!- The current context is wrapped in our controller instance }}
+ {{/with}}
```

- @param {Function} tryable The function to run the try callback
- @param {Function} finalizer The function to run the finally callback
- @param {Object} [binding] The optional calling object. Defaults to 'this'
- @return {*} The return value is the that of the finalizer,
- unless that value is undefined, in which case it is the return value
- of the tryable
+ In the above example, the template provided to the `{{with}}` block is now wrapped in the
+ `userBlogPost` controller, which provides a very elegant way to decorate the context with custom
+ functions/properties.

+ ### `bind-attr` and the `class` attribute
- // ........................................
- // TYPING & ARRAY MESSAGING
- //
+ `bind-attr` supports a special syntax for handling a number of cases unique
+ to the `class` DOM element attribute. The `class` attribute combines
+ multiple discrete values into a single attribute as a space-delimited
+ list of strings. Each string can be:
- var TYPE_MAP = {};
- var t = "Boolean Number String Function Array Date RegExp Object".split(" ");
- forEach.call(t, function(name) {
- TYPE_MAP[ "[object " + name + "]" ] = name.toLowerCase();
- });
+ * a string return value of an object's property.
+ * a boolean return value of an object's property
+ * a hard-coded value
- var toString = Object.prototype.toString;
+ A string return value works identically to other uses of `bind-attr`. The
+ return value of the property will become the value of the attribute. For
+ example, the following view and template:
- var EmberObject;
+ ```javascript
+ AView = View.extend({
+ someProperty: function() {
+ return "aValue";
+ }.property()
+ })
+ ```
- /**
- Returns a consistent type for the passed item.
+ ```handlebars
+ <img {{bind-attr class="view.someProperty}}>
+ ```
- Use this instead of the built-in `typeof` to get the type of an item.
- It will return the same result across all browsers and includes a bit
- more detail. Here is what will be returned:
+ Result in the following rendered output:
- | Return Value | Meaning |
- |---------------|------------------------------------------------------|
- | 'string' | String primitive or String object. |
- | 'number' | Number primitive or Number object. |
- | 'boolean' | Boolean primitive or Boolean object. |
- | 'null' | Null value |
- | 'undefined' | Undefined value |
- | 'function' | A function |
- | 'array' | An instance of Array |
- | 'regexp' | An instance of RegExp |
- | 'date' | An instance of Date |
- | 'class' | An Ember class (created using Ember.Object.extend()) |
- | 'instance' | An Ember object instance |
- | 'error' | An instance of the Error object |
- | 'object' | A JavaScript object not inheriting from Ember.Object |
+ ```html
+ <img class="aValue">
+ ```
+
+ A boolean return value will insert a specified class name if the property
+ returns `true` and remove the class name if the property returns `false`.
- Examples:
+ A class name is provided via the syntax
+ `somePropertyName:class-name-if-true`.
```javascript
- Ember.typeOf(); // 'undefined'
- Ember.typeOf(null); // 'null'
- Ember.typeOf(undefined); // 'undefined'
- Ember.typeOf('michael'); // 'string'
- Ember.typeOf(new String('michael')); // 'string'
- Ember.typeOf(101); // 'number'
- Ember.typeOf(new Number(101)); // 'number'
- Ember.typeOf(true); // 'boolean'
- Ember.typeOf(new Boolean(true)); // 'boolean'
- Ember.typeOf(Ember.makeArray); // 'function'
- Ember.typeOf([1,2,90]); // 'array'
- Ember.typeOf(/abc/); // 'regexp'
- Ember.typeOf(new Date()); // 'date'
- Ember.typeOf(Ember.Object.extend()); // 'class'
- Ember.typeOf(Ember.Object.create()); // 'instance'
- Ember.typeOf(new Error('teamocil')); // 'error'
+ AView = View.extend({
+ someBool: true
+ })
+ ```
- // "normal" JavaScript object
- Ember.typeOf({a: 'b'}); // 'object'
+ ```handlebars
+ <img {{bind-attr class="view.someBool:class-name-if-true"}}>
```
- @method typeOf
- @for Ember
- @param {Object} item the item to check
- @return {String} the type
- */
- function typeOf(item) {
- var ret, modulePath;
+ Result in the following rendered output:
- // ES6TODO: Depends on Ember.Object which is defined in runtime.
- if (typeof EmberObject === "undefined") {
- modulePath = 'ember-runtime/system/object';
- if (requirejs._eak_seen[modulePath]) {
- EmberObject = requireModule(modulePath)['default'];
- }
- }
+ ```html
+ <img class="class-name-if-true">
+ ```
- ret = (item === null || item === undefined) ? String(item) : TYPE_MAP[toString.call(item)] || 'object';
+ An additional section of the binding can be provided if you want to
+ replace the existing class instead of removing it when the boolean
+ value changes:
- if (ret === 'function') {
- if (EmberObject && EmberObject.detect(item)) ret = 'class';
- } else if (ret === 'object') {
- if (item instanceof Error) ret = 'error';
- else if (EmberObject && item instanceof EmberObject) ret = 'instance';
- else if (item instanceof Date) ret = 'date';
- }
+ ```handlebars
+ <img {{bind-attr class="view.someBool:class-name-if-true:class-name-if-false"}}>
+ ```
- return ret;
- };
+ A hard-coded value can be used by prepending `:` to the desired
+ class name: `:class-name-to-always-apply`.
- /**

- function inspect(obj) {
- var type = typeOf(obj);

- return '[' + obj + ']';
- }
- if (type !== 'object') {
- return obj + '';
- }
+ ```html
+ <img class="class-name-to-always-apply">

- var v, ret = [];

- if (obj.hasOwnProperty(key)) {

- ret.push(key + ": " + v);
- }
- }
- return "{" + ret.join(", ") + "}";

+ All three strategies - string return value, boolean return value, and
+ hard-coded value – can be combined in a single declaration:
- // The following functions are intentionally minified to keep the functions
- // below Chrome's function body size inlining limit of 600 chars.

+ `{{collection}}`'s primary use is as a block helper with a `contentBinding`

+ App.ApplicationRoute = Ember.Route.extend({
+ model: function(){
+ return [{name: 'Yehuda'},{name: 'Tom'},{name: 'Peter'}];
}
+ });
+ ```
- debouncee = [target, method, timer];
+ The following HTML will result:

+ ```html
+ <div class="ember-view">
+ <div class="ember-view">Hi Yehuda</div>
+ <div class="ember-view">Hi Tom</div>

+ template: Ember.Handlebars.compile("Greetings {{view.content.name}}")
+ });
+ ```
- cancel: function(timer) {

+ ```
- _cancelItem: function(findMethod, array, timer){
- var item,
- index;
+ ### Specifying a CollectionView subclass
- if (timer.length < 3) { return false; }
+ By default the `{{collection}}` helper will create an instance of
+ `Ember.CollectionView`. You can supply a `Ember.CollectionView` subclass to
+ the helper by passing it as the first argument:
- index = findMethod(timer[0], timer[1]);
+ ```handlebars
+ {{#collection "my-custom-collection" content=model}}
+ Hi {{view.content.name}}
+ {{/collection}}
+ ```
- if(index > -1) {
+ This example would look for the class `App.MyCustomCollection`.
- item = array[index];
+ ### Forwarded `item.*`-named Options
- if(item[2] === timer[2]){
- array.splice(index, 1);
- clearTimeout(timer[2]);
- return true;
- }
- }
+ As with the `{{view}}`, helper options passed to the `{{collection}}` will be
+ set on the resulting `Ember.CollectionView` as properties. Additionally,
+ options prefixed with `item` will be applied to the views rendered for each
+ item (note the camelcasing):
- return false;
- }
+ ```handlebars
+ {{#collection content=model
+ itemTagName="p"
+ itemClassNames="greeting"}}
+ Howdy {{view.content.name}}
+ {{/collection}}
+ ```
- };
+ Will result in the following HTML structure:
- Backburner.prototype.schedule = Backburner.prototype.defer;
- Backburner.prototype.scheduleOnce = Backburner.prototype.deferOnce;
- Backburner.prototype.later = Backburner.prototype.setTimeout;
+ ```html
+ <div class="ember-view">

- `RSVP.allSettled` is similar to `RSVP.all`, but instead of implementing
- a fail-fast method, it waits until all the promises have returned and
- shows you all the results. This is useful if you want to handle multiple
- promises' failure states together as a set.
+ ```handlebars
+ <ul>
+ {{each developers itemViewClass="person"}}
+ </ul>
+ ```
- Returns a promise that is fulfilled when all the given promises have been
- settled. The return promise is fulfilled with an array of the states of
- the promises passed into the `promises` array argument.
+ ### Specifying an alternative view for no items (else)
- Each state object will either indicate fulfillment or rejection, and
- provide the corresponding value or reason. The states will take one of
- the following formats:
+ The `emptyViewClass` option provides the same flexibility to the `{{else}}`
+ case of the each helper.
```javascript
- { state: 'fulfilled', value: value }
- or
- { state: 'rejected', reason: reason }
+ App.NoPeopleView = Ember.View.extend({
+ tagName: 'li',
+ template: 'No person is available, sorry'
+ });
```
- Example:
+ ```handlebars
+ <ul>
+ {{#each developers emptyViewClass="no-people"}}
+ <li>{{name}}</li>
+ {{/each}}
+ </ul>
+ ```
+
+ ### Wrapping each item in a controller
+
+ Controllers in Ember manage state and decorate data. In many cases,
+ providing a controller for each item in a list can be useful.
+ Specifically, an {{#crossLink "Ember.ObjectController"}}Ember.ObjectController{{/crossLink}}
+ should probably be used. Item controllers are passed the item they
+ will present as a `model` property, and an object controller will
+ proxy property lookups to `model` for us.
+
+ This allows state and decoration to be added to the controller
+ while any other property lookups are delegated to the model. An example:
```javascript
- var promise1 = RSVP.Promise.resolve(1);
- var promise2 = RSVP.Promise.reject(new Error('2'));
- var promise3 = RSVP.Promise.reject(new Error('3'));
- var promises = [ promise1, promise2, promise3 ];
+ App.RecruitController = Ember.ObjectController.extend({
+ isAvailableForHire: function() {
+ return !this.get('isEmployed') && this.get('isSeekingWork');
+ }.property('isEmployed', 'isSeekingWork')
+ })
+ ```
- RSVP.allSettled(promises).then(function(array){
- // array == [
- // { state: 'fulfilled', value: 1 },
- // { state: 'rejected', reason: Error },
- // { state: 'rejected', reason: Error }
- // ]
- // Note that for the second item, reason.message will be "2", and for the
- // third item, reason.message will be "3".
- }, function(error) {
- // Not run. (This block would only be called if allSettled had failed,
- // for instance if passed an incorrect argument type.)
- });
+ ```handlebars
+ {{#each person in developers itemController="recruit"}}
+ {{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}}
+ {{/each}}
```
- @method allSettled
- @for RSVP
- @param {Array} promises
- @param {String} label - optional string that describes the promise.
- Useful for tooling.
- @return {Promise} promise that is fulfilled with an array of the settled
- states of the constituent promises.
- @static
- */
+ ### (Experimental) Grouped Each
- __exports__["default"] = function allSettled(entries, label) {
- return new Promise(function(resolve, reject) {
- if (!isArray(entries)) {
- throw new TypeError('You must pass an array to allSettled.');
- }
+ If a list's membership often changes, but properties of items in that
+ group rarely change, a significant improvement in template rendering
+ time can be achieved by using the experimental [group helper](https://github.com/emberjs/group-helper).
- var remaining = entries.length;
- var entry;
+ ```handlebars
+ {{#group}}
+ {{#each people}}
+ {{firstName}} {{lastName}}
+ {{/each}}
+ {{/group}}
+ ```
- if (remaining === 0) {
- resolve([]);
- return;
- }
+ When the membership of `people` changes, or when any property changes, the entire
+ `{{#group}}` block will be re-rendered.
- var results = new Array(remaining);
+ An `{{#each}}` inside the `{{#group}}` helper can opt-out of the special group
+ behavior by passing the `groupedRows` option. For example:
- function fulfilledResolver(index) {
- return function(value) {
- resolveAll(index, fulfilled(value));
- };
- }
+ ```handlebars
+ {{#group}}
+ {{#each dealers}}
+ {{! uses group's special behavior }}
+ {{firstName}} {{lastName}}
+ {{/each}}
- function rejectedResolver(index) {
- return function(reason) {
- resolveAll(index, rejected(reason));
- };
- }
+ {{#each car in cars groupedRows=true}}
+ {{! does not use group's special behavior }}
+ {{car.make}} {{car.model}} {{car.color}}
+ {{/each}}
+ {{/group}}
+ ```
- function resolveAll(index, value) {
- results[index] = value;
- if (--remaining === 0) {
- resolve(results);
- }
- }
+ Any change to the `dealers` collection will cause the entire group to be re-rendered.
+ Changes to the `cars` collection will be re-rendered individually, as they are with
+ normal `{{#each}}` usage.
- for (var index = 0; index < entries.length; index++) {
- entry = entries[index];
+ `{{#group}}` is implemented with an `itemViewClass`, so specifying an `itemViewClass`
+ on an `{{#each}}` will also disable the special re-rendering behavior.
- if (isNonThenable(entry)) {
- resolveAll(index, fulfilled(entry));
- } else {
- Promise.cast(entry).then(fulfilledResolver(index), rejectedResolver(index));
- }
- }
- }, label);

/**
- `RSVP.map` is similar to JavaScript's native `map` method, except that it
- waits for all promises to become fulfilled before running the `mapFn` on
- each item in given to `promises`. `RSVP.map` returns a promise that will
- become fulfilled with the result of running `mapFn` on the values the promises
- become fulfilled with.
+ `{{view}}` inserts a new instance of an `Ember.View` into a template passing its
+ options to the `Ember.View`'s `create` method and using the supplied block as
+ the view's own template.
- For example:
+ An empty `<body>` and the following template:
- ```javascript
+ ```handlebars
+ A span:
+ {{#view tagName="span"}}
+ hello.
+ {{/view}}
+ ```
- var promise1 = RSVP.resolve(1);
- var promise2 = RSVP.resolve(2);
- var promise3 = RSVP.resolve(3);
- var promises = [ promise1, promise2, promise3 ];
+ Will result in HTML structure:
- var mapFn = function(item){
- return item + 1;
- };
+ ```html
+ <body>
+ <!-- Note: the handlebars template script
+ also results in a rendered Ember.View
+ which is the outer <div> here -->
- RSVP.map(promises, mapFn).then(function(result){
- // result is [ 2, 3, 4 ]
- });
+ <div class="ember-view">
+ A span:
+ <span id="ember1" class="ember-view">
+ Hello.
+ </span>
+ </div>
+ </body>
```
- If any of the `promises` given to `RSVP.map` are rejected, the first promise
- that is rejected will be given as an argument to the returned promise's
- rejection handler. For example:
-
- ```javascript
- var promise1 = RSVP.resolve(1);
- var promise2 = RSVP.reject(new Error("2"));
- var promise3 = RSVP.reject(new Error("3"));
- var promises = [ promise1, promise2, promise3 ];
+ ### `parentView` setting
- var mapFn = function(item){
- return item + 1;
- };
+ The `parentView` property of the new `Ember.View` instance created through
+ `{{view}}` will be set to the `Ember.View` instance of the template where
+ `{{view}}` was called.
- RSVP.map(promises, mapFn).then(function(array){
- // Code here never runs because there are rejected promises!
- }, function(reason) {
- // reason.message === "2"
+ ```javascript
+ aView = Ember.View.create({
+ template: Ember.Handlebars.compile("{{#view}} my parent: {{parentView.elementId}} {{/view}}")
});
- ```
-
- `RSVP.map` will also wait if a promise is returned from `mapFn`. For example,
- say you want to get all comments from a set of blog posts, but you need
- the blog posts first becuase they contain a url to those comments.
- ```javscript
+ aView.appendTo('body');
+ ```
- var mapFn = function(blogPost){
- // getComments does some ajax and returns an RSVP.Promise that is fulfilled
- // with some comments data
- return getComments(blogPost.comments_url);
- };
+ Will result in HTML structure:
- // getBlogPosts does some ajax and returns an RSVP.Promise that is fulfilled
- // with some blog post data
- RSVP.map(getBlogPosts(), mapFn).then(function(comments){
- // comments is the result of asking the server for the comments
- // of all blog posts returned from getBlogPosts()
- });
+ ```html
+ <div id="ember1" class="ember-view">
+ <div id="ember2" class="ember-view">
+ my parent: ember1

+ {{/view}}
+ ```

- `RSVP.denodeify` takes a "node-style" function and returns a function that
- will return an `RSVP.Promise`. You can use `denodeify` in Node.js or the
- browser when you'd prefer to use promises over using callbacks. For example,
- `denodeify` transforms the following:
+ ```html
+ <div class="ember-view">
+ <span id="ember2" class="ember-view a-custom-class">
+ hello.
+ </span>
+ </div>
+ ```
- ```javascript
- var fs = require('fs');
+ ### Supplying a different view class
- fs.readFile('myfile.txt', function(err, data){
- if (err) return handleError(err);
- handleData(data);
- });
+ `{{view}}` can take an optional first argument before its supplied options to
+ specify a path to a custom view class.
+
+ ```handlebars
+ {{#view "custom"}}{{! will look up App.CustomView }}
+ hello.
+ {{/view}}
```
- into:
+ The first argument can also be a relative path accessible from the current
+ context.
```javascript
- var fs = require('fs');
+ MyApp = Ember.Application.create({});
+ MyApp.OuterView = Ember.View.extend({
+ innerViewClass: Ember.View.extend({
+ classNames: ['a-custom-view-class-as-property']
+ }),
+ template: Ember.Handlebars.compile('{{#view view.innerViewClass}} hi {{/view}}')
+ });
- var readFile = RSVP.denodeify(fs.readFile);
+ MyApp.OuterView.create().appendTo('body');
+ ```
- readFile('myfile.txt').then(handleData, handleError);
+ Will result in the following HTML:
+
+ ```html
+ <div id="ember1" class="ember-view">
+ <div id="ember2" class="ember-view a-custom-view-class-as-property">
+ hi
+ </div>
+ </div>
```
- Using `denodeify` makes it easier to compose asynchronous operations instead
- of using callbacks. For example, instead of:
+ ### Blockless use
- ```javascript
- var fs = require('fs');
- var log = require('some-async-logger');
+ If you supply a custom `Ember.View` subclass that specifies its own template
+ or provide a `templateName` option to `{{view}}` it can be used without
+ supplying a block. Attempts to use both a `templateName` option and supply a
+ block will throw an error.
- fs.readFile('myfile.txt', function(err, data){
- if (err) return handleError(err);
- fs.writeFile('myfile2.txt', data, function(err){
- if (err) throw err;
- log('success', function(err) {
- if (err) throw err;
- });
- });
+ ```javascript
+ var App = Ember.Application.create();
+ App.WithTemplateDefinedView = Ember.View.extend({
+ templateName: 'defined-template'
});
```
- You can chain the operations together using `then` from the returned promise:
+ ```handlebars
+ {{! application.hbs }}
+ {{view 'with-template-defined'}}
+ ```
- ```javascript
- var fs = require('fs');
- var denodeify = RSVP.denodeify;
- var readFile = denodeify(fs.readFile);
- var writeFile = denodeify(fs.writeFile);
- var log = denodeify(require('some-async-logger'));
+ ```handlebars
+ {{! defined-template.hbs }}
+ Some content for the defined template view.
+ ```
- readFile('myfile.txt').then(function(data){
- return writeFile('myfile2.txt', data);
- }).then(function(){
- return log('SUCCESS');
- }).then(function(){
- // success handler
- }, function(reason){
- // rejection handler
+ ### `viewName` property
+
+ You can supply a `viewName` option to `{{view}}`. The `Ember.View` instance
+ will be referenced as a property of its parent view by this name.
+
+ ```javascript
+ aView = Ember.View.create({
+ template: Ember.Handlebars.compile('{{#view viewName="aChildByName"}} hi {{/view}}')
});
+
+ aView.appendTo('body');
+ aView.get('aChildByName') // the instance of Ember.View created by {{view}} helper

/**
- Promise objects represent the eventual result of an asynchronous operation. The
- primary way of interacting with a promise is through its `then` method, which
- registers callbacks to receive either a promise’s eventual value or the reason
- why the promise cannot be fulfilled.
-
- Terminology
- -----------
+ @module ember
+ @submodule ember-handlebars
+ */
- - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
- - `thenable` is an object or function that defines a `then` method.
- - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
- - `exception` is a value that is thrown using the throw statement.
- - `reason` is a value that indicates why a promise was rejected.
- - `settled` the final resting state of a promise, fulfilled or rejected.
+ var Ember = __dependency1__["default"];
+ // var emberAssert = Ember.assert;
- A promise can be in one of three states: pending, fulfilled, or rejected.
+ var get = __dependency2__.get;
- Promises that are fulfilled have a fulfillment value and are in the fulfilled
- state. Promises that are rejected have a rejection reason and are in the
- rejected state. A fulfillment value is never a thenable. Similarly, a
- rejection reason is never a thenable.
+ /**
+ `{{yield}}` denotes an area of a template that will be rendered inside
+ of another template. It has two main uses:
- Promises can also be said to *resolve* a value. If this value is also a
- promise, then the original promise's settled state will match the value's
- settled state. So a promise that *resolves* a promise that rejects will
- itself reject, and a promise that *resolves* a promise that fulfills will
- itself fulfill.
+ ### Use with `layout`
+ When used in a Handlebars template that is assigned to an `Ember.View`
+ instance's `layout` property Ember will render the layout template first,
+ inserting the view's own rendered output at the `{{yield}}` location.
+ An empty `<body>` and the following application code:
- Basic Usage:
- ------------
+ ```javascript
+ AView = Ember.View.extend({
+ classNames: ['a-view-with-layout'],
+ layout: Ember.Handlebars.compile('<div class="wrapper">{{yield}}</div>'),
+ template: Ember.Handlebars.compile('<span>I am wrapped</span>')
+ });
- ```js
- var promise = new Promise(function(resolve, reject) {
- // on success
- resolve(value);
+ aView = AView.create();
+ aView.appendTo('body');
+ ```
- // on failure
- reject(reason);
- });
+ Will result in the following HTML output:
- promise.then(function(value) {

+ ```html
+ <body>
+ <div class='ember-view a-view-with-layout'>
+ <div class="wrapper">
+ <span>I am wrapped</span>
+ </div>
+ </div>
+ </body>
```
- Advanced Usage:
- ---------------
+ The `yield` helper cannot be used outside of a template assigned to an
+ `Ember.View`'s `layout` property and will throw an error if attempted.
- Promises shine when abstracting away asynchronous interactions such as
- `XMLHttpRequest`s.
+ ```javascript
+ BView = Ember.View.extend({
+ classNames: ['a-view-with-layout'],
+ template: Ember.Handlebars.compile('{{yield}}')
+ });
- ```js
- function getJSON(url) {
- return new Promise(function(resolve, reject){
- var xhr = new XMLHttpRequest();
+ bView = BView.create();
+ bView.appendTo('body');
- xhr.open('GET', url);
- xhr.onreadystatechange = handler;
- xhr.responseType = 'json';
- xhr.setRequestHeader('Accept', 'application/json');
- xhr.send();
+ // throws
+ // Uncaught Error: assertion failed:
+ // You called yield in a template that was not a layout
+ ```
- function handler() {
- if (this.readyState === this.DONE) {
- if (this.status === 200) {
- resolve(this.response);
- } else {
- reject(new Error("getJSON: `" + url + "` failed with status: [" + this.status + "]");
- }
- }
- };
- });
- }
+ ### Use with Ember.Component
+ When designing components `{{yield}}` is used to denote where, inside the component's
+ template, an optional block passed to the component should render:
- getJSON('/posts.json').then(function(json) {
- // on fulfillment
- }, function(reason) {
- // on rejection
- });
+ ```handlebars
+ <!-- application.hbs -->
+ {{#labeled-textfield value=someProperty}}
+ First name:
+ {{/labeled-textfield}}
```
- Unlike callbacks, promises are great composable primitives.
+ ```handlebars
+ <!-- components/labeled-textfield.hbs -->
+ <label>
+ {{yield}} {{input value=value}}
+ </label>
+ ```
- ```js
- Promise.all([
- getJSON('/posts'),
- getJSON('/comments')
- ]).then(function(values){
- values[0] // => postsJSON
- values[1] // => commentsJSON
+ Result:
- return values;
- });
+ ```html
+ <label>
+ First name: <input type="text" />
+ </label>
```

- * `RSVP.Promise.cast` is a way of casting incoming thenables or promise subclasses to

+ An `Ember.Binding` connects the properties of two objects so that whenever
+ the value of one property changes, the other property will be changed also.
- The default behaviour is for lookup to return a singleton instance.
- The singleton is scoped to the container, allowing multiple containers
- to all have their own locally scoped singletons.
+ ## Automatic Creation of Bindings with `/^*Binding/`-named Properties
- ```javascript
- var container = new Container();
- container.register('api:twitter', Twitter);
+ You do not usually create Binding objects directly but instead describe
+ bindings in your class or object definition using automatic binding
+ detection.
- var twitter = container.lookup('api:twitter');
+ Properties ending in a `Binding` suffix will be converted to `Ember.Binding`
+ instances. The value of this property should be a string representing a path
+ to another object or a custom binding instance created using Binding helpers
+ (see "One Way Bindings"):
- twitter instanceof Twitter; // => true
+ ```
+ valueBinding: "MyApp.someController.title"
+ ```
- // by default the container will return singletons
- var twitter2 = container.lookup('api:twitter');
- twitter instanceof Twitter; // => true
+ This will create a binding from `MyApp.someController.title` to the `value`
+ property of your object instance automatically. Now the two values will be
+ kept in sync.
- twitter === twitter2; //=> true
- ```
+ ## One Way Bindings
- If singletons are not wanted an optional flag can be provided at lookup.
+ One especially useful binding customization you can use is the `oneWay()`
+ helper. This helper tells Ember that you are only interested in
+ receiving changes on the object you are binding from. For example, if you
+ are binding to a preference and you want to be notified if the preference
+ has changed, but your object will not be changing the preference itself, you
+ could do:
- ```javascript
- var container = new Container();
- container.register('api:twitter', Twitter);
+ ```
+ bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
+ ```
- var twitter = container.lookup('api:twitter', { singleton: false });
- var twitter2 = container.lookup('api:twitter', { singleton: false });
+ This way if the value of `MyApp.preferencesController.bigTitles` changes the
+ `bigTitles` property of your object will change also. However, if you
+ change the value of your `bigTitles` property, it will not update the
+ `preferencesController`.
- twitter === twitter2; //=> false
- ```
+ One way bindings are almost twice as fast to setup and twice as fast to
+ execute because the binding only has to worry about changes to one side.
- @method lookup
- @param {String} fullName
- @param {Object} options
- @return {any}
- */
- lookup: function(fullName, options) {
- validateFullName(fullName);
- return lookup(this, this.normalize(fullName), options);
- },
+ You should consider using one way bindings anytime you have an object that
+ may be created frequently and you do not intend to change a property; only
+ to monitor it for changes (such as in the example above).
- /**
- Given a fullName return the corresponding factory.

+ All of the examples above show you how to configure a custom binding, but the
+ result of these customizations will be a binding template, not a fully active
+ Binding instance. The binding will actually become active only when you
+ instantiate the object the binding belongs to. It is useful however, to
+ understand what actually happens when the binding is activated.
- /**
- Given a fullName check if the container is aware of its factory
- or singleton instance.
+ For a binding to function it must have at least a `from` property and a `to`
+ property. The `from` property path points to the object/key that you want to
+ bind from while the `to` path points to the object/key you want to bind to.
- @method has
- @param {String} fullName
- @return {Boolean}
- */
- has: function(fullName) {

- },
+ When you define a custom binding, you are usually describing the property
+ you want to bind from (such as `MyApp.someController.value` in the examples
+ above). When your object is created, it will automatically assign the value
+ you want to bind `to` based on the name of your binding key. In the
+ examples above, during init, Ember objects will effectively call
+ something like this on your binding:
- /**
- Allow registering options for all factories of a type.
+ ```javascript
+ binding = Ember.Binding.from("valueBinding").to("value");
+ ```
- ```javascript
- var container = new Container();
+ This creates a new binding instance based on the template you provide, and
+ sets the to path to the `value` property of the new object. Now that the
+ binding is fully configured with a `from` and a `to`, it simply needs to be
+ connected to become active. This is done through the `connect()` method:
- // if all of type `connection` must not be singletons
- container.optionsForType('connection', { singleton: false });
+ ```javascript
+ binding.connect(this);
+ ```
- container.register('connection:twitter', TwitterConnection);
- container.register('connection:facebook', FacebookConnection);
+ Note that when you connect a binding you pass the object you want it to be
+ connected to. This object will be used as the root for both the from and
+ to side of the binding when inspecting relative paths. This allows the
+ binding to be automatically inherited by subclassed objects as well.
- var twitter = container.lookup('connection:twitter');
- var twitter2 = container.lookup('connection:twitter');
+ This also allows you to bind between objects using the paths you declare in
+ `from` and `to`:
- twitter === twitter2; // => false
+ ```javascript
+ // Example 1
+ binding = Ember.Binding.from("App.someObject.value").to("value");
+ binding.connect(this);
- var facebook = container.lookup('connection:facebook');
- var facebook2 = container.lookup('connection:facebook');
+ // Example 2
+ binding = Ember.Binding.from("parentView.value").to("App.someObject.value");
+ binding.connect(this);
+ ```
- facebook === facebook2; // => false
- ```
+ Now that the binding is connected, it will observe both the from and to side
+ and relay changes.
- @method optionsForType
- @param {String} type

- */
- optionsForType: function(type, options) {
- if (this.parent) { illegalChildOperation('optionsForType'); }
+ If you ever needed to do so (you almost never will, but it is useful to
+ understand this anyway), you could manually create an active binding by
+ using the `Ember.bind()` helper method. (This is the same method used by
+ to setup your bindings on objects):
- this._typeOptions.set(type, options);
- },
+ ```javascript
+ Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value");
+ ```
- /**
- @method options
- @param {String} type
- @param {Object} options
- */
- options: function(type, options) {
- this.optionsForType(type, options);
- },
+ Both of these code fragments have the same effect as doing the most friendly
+ form of binding creation like so:
- /**
- Used only via `injection`.
+ ```javascript
+ MyApp.anotherObject = Ember.Object.create({
+ valueBinding: "MyApp.someController.value",
- Provides a specialized form of injection, specifically enabling
- all objects of one type to be injected with a reference to another
- object.
+ // OTHER CODE FOR THIS OBJECT...
+ });
+ ```
- For example, provided each object of type `controller` needed a `router`.
- one would do the following:

- `previousValues` is important Ember coalesces item property changes via

+ }
- The `removedItem` and `addedItem` functions should return the accumulated
- value. It is acceptable to not return anything (ie return undefined)
- to invalidate the computation. This is generally not a good idea for
- arrayComputed but it's used in eg max and min.

+ @static

- `item` - the element added or removed from the array
+ Ember.FEATURES = Ember.ENV.FEATURES || {};
- `changeMeta` - An object which contains meta information about the
- change. It contains the following properties:
+ /**
+ Test that a feature is enabled. Parsed by Ember's build tools to leave
+ experimental features out of beta/stable builds.
- - `property` the computed property
- - `propertyName` the name of the property on the object
- - `index` the index of the added or removed item
- - `item` the added or removed item: this is exactly the same as
- the second arg
- - `arrayChanged` the array that triggered the change. Can be

- `changeMeta` will also contain the following property:

- `previousValues` is important Ember coalesces item property changes via

- The `removedItem` and `addedItem` functions should return the accumulated
- value. It is acceptable to not return anything (ie return undefined)
- to invalidate the computation. This is generally not a good idea for
- arrayComputed but it's used in eg max and min.
+ // ..........................................................
+ // BOOTSTRAP
+ //
- Note that observers will be fired if either of these functions return a value
- that differs from the accumulated value. When returning an object that
- mutates in response to array changes, for example an array that maps
- everything from some other array (see `Ember.computed.map`), it is usually
- important that the *same* array be returned to avoid accidentally triggering observers.

/**
- `Ember.ArrayController` provides a way for you to publish a collection of
- objects so that you can easily bind to the collection from a Handlebars
- `#each` helper, an `Ember.CollectionView`, or other controllers.
-
- The advantage of using an `ArrayController` is that you only have to set up
- your view bindings once; to change what's displayed, simply swap out the
- `content` property on the controller.
-
- For example, imagine you wanted to display a list of items fetched via an XHR
- request. Create an `Ember.ArrayController` and set its `content` property:
+ To get multiple properties at once, call `Ember.getProperties`
+ with an object followed by a list of strings or an array:
```javascript
- MyApp.listController = Ember.ArrayController.create();
-
- $.get('people.json', function(data) {
- MyApp.listController.set('content', data);
- });
+ Ember.getProperties(record, 'firstName', 'lastName', 'zipCode');
+ // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
```
- Then, create a view that binds to your new controller:
+ is equivalent to:
- ```handlebars
- {{#each MyApp.listController}}
- {{firstName}} {{lastName}}
- {{/each}}
+ ```javascript
+ Ember.getProperties(record, ['firstName', 'lastName', 'zipCode']);
+ // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
```
- Although you are binding to the controller, the behavior of this controller
- is to pass through any methods or properties to the underlying array. This
- capability comes from `Ember.ArrayProxy`, which this class inherits from.
+ @method getProperties
+ @param obj
+ @param {String...|Array} list of keys to get
+ @return {Hash}
+ */
+ __exports__["default"] = function getProperties(obj) {
+ var ret = {};
+ var propertyNames = arguments;
+ var i = 1;
- Sometimes you want to display computed properties within the body of an

- present on those items. To do this, set `itemController` to the name of a
- controller (probably an `ObjectController`) that will wrap each individual item.

+ The purpose of the Ember Instrumentation module is
+ to provide efficient, general-purpose instrumentation
+ for Ember.
- ```handlebars
- {{#each post in controller}}
- <li>{{title}} ({{titleLength}} characters)</li>
- {{/each}}
- ```
+ Subscribe to a listener by using `Ember.subscribe`:
```javascript
- App.PostsController = Ember.ArrayController.extend({
- itemController: 'post'
- });
+ Ember.subscribe("render", {
+ before: function(name, timestamp, payload) {
- App.PostController = Ember.ObjectController.extend({
- // the `title` property will be proxied to the underlying post.
+ },
- titleLength: function() {
- return this.get('title').length;
- }.property('title')
+ after: function(name, timestamp, payload) {
+
+ }
});
```
- In some cases it is helpful to return a different `itemController` depending
- on the particular item. Subclasses can do this by overriding
- `lookupItemController`.
+ If you return a value from the `before` callback, that same
+ value will be passed as a fourth parameter to the `after`
+ callback.
- For example:
+ Instrument a block of code by using `Ember.instrument`:
```javascript
- App.MyArrayController = Ember.ArrayController.extend({
- lookupItemController: function( object ) {
- if (object.get('isSpecial')) {
- return "special"; // use App.SpecialController
- } else {
- return "regular"; // use App.RegularController
- }
- }
- });
+ Ember.instrument("render.handlebars", payload, function() {
+ // rendering logic
+ }, binding);
```
- The itemController instances will have a `parentController` property set to
- the `ArrayController` instance.
+ Event names passed to `Ember.instrument` are namespaced
+ by periods, from more general to more specific. Subscribers
+ can listen for events by whatever level of granularity they
+ are interested in.
- @class ArrayController
+ In the above example, the event is `render.handlebars`,
+ and the subscriber listened for all events beginning with
+ `render`. It would receive callbacks for events named
+ `render`, `render.handlebars`, `render.container`, or
+ even `render.handlebars.layout`.

- This mixin defines the common interface implemented by enumerable objects

+ __exports__.immediateObserver = immediateObserver;/**
+ When observers fire, they are called with the arguments `obj`, `keyName`.
- This mixin is applied automatically to the Array class on page load, so you
- can use any of these methods on simple arrays. If Array already implements
- one of these methods, the mixin will not override them.
+ Note, `@each.property` observer is called per each add or replace of an element
+ and it's not called with a specific enumeration item.
- ## Writing Your Own Enumerable
+ A `beforeObserver` fires before a property changes.
- To make your own custom class enumerable, you need two items:
+ A `beforeObserver` is an alternative form of `.observesBefore()`.
- 1. You must have a length property. This property should change whenever
- the number of items in your enumerable object changes. If you use this
- with an `Ember.Object` subclass, you should be sure to change the length
- property using `set().`
+ ```javascript
+ App.PersonView = Ember.View.extend({
+ friends: [{ name: 'Tom' }, { name: 'Stefan' }, { name: 'Kris' }],
- 2. You must implement `nextObject().` See documentation.
+ valueWillChange: Ember.beforeObserver('content.value', function(obj, keyName) {
+ this.changingFrom = obj.get(keyName);
+ }),
- Once you have these two methods implemented, apply the `Ember.Enumerable` mixin
- to your class and you will be able to enumerate the contents of your object
- like any other collection.
+ valueDidChange: Ember.observer('content.value', function(obj, keyName) {
+ // only run if updating a value already in the DOM
+ if (this.get('state') === 'inDOM') {
+ var color = obj.get(keyName) > this.changingFrom ? 'green' : 'red';
+ // logic
+ }
+ }),
- ## Using Ember Enumeration with Other Libraries
+ friendsDidChange: Ember.observer('friends.@each.name', function(obj, keyName) {
+ // some logic
+ // obj.get(keyName) returns friends array
+ })
+ });
+ ```
- Many other libraries provide some kind of iterator or enumeration like
- facility. This is often where the most common API conflicts occur.
- Ember's API is designed to be as friendly as possible with other
- libraries by implementing only methods that mostly correspond to the
- JavaScript 1.8 API.

+ Provides a useful utility for when integrating with non-Ember libraries

- var Mixin = __dependency1__.Mixin;
- var get = __dependency2__.get;
- var set = __dependency3__.set;
+ Ember utilizes a run-loop to batch and coalesce changes. This works by
+ marking the start and end of Ember-related Javascript execution.
- /**
- The `Ember.Freezable` mixin implements some basic methods for marking an
- object as frozen. Once an object is frozen it should be read only. No changes
- may be made the internal state of the object.
+ When using events such as a View's click handler, Ember wraps the event
+ handler in a run-loop, but when integrating with non-Ember libraries this
+ can be tedious.
+
+ For example, the following is rather verbose but is the correct way to combine
+ third-party events and Ember code.
- ## Enforcement
+ ```javascript
+ var that = this;
+ jQuery(window).on('resize', function(){
+ run(function(){
+ that.handleResize();
+ });
+ });
+ ```
- To fully support freezing in your subclass, you must include this mixin and
- override any method that might alter any property on the object to instead
- raise an exception. You can check the state of an object by checking the
- `isFrozen` property.
+ To reduce the boilerplate, the following can be used to construct a
+ run-loop-wrapped callback handler.
- Although future versions of JavaScript may support language-level freezing
- object objects, that is not the case today. Even if an object is freezable,
- it is still technically possible to modify the object, even though it could
- break other parts of your application that do not expect a frozen object to
- change. It is, therefore, very important that you always respect the
- `isFrozen` property on all freezable objects.
+ ```javascript
+ jQuery(window).on('resize', run.bind(this, this.handleResize));
+ ```
- ## Example Usage
+ @method bind
+ @namespace Ember
+ @param {Object} [target] target of method to call
+ @param {Function|String} method Method to invoke.
+ May be a function or a string. If you pass a string
+ then it will be looked up on the passed target.
+ @param {Object} [args*] Any additional arguments you wish to pass to the method.
+ @return {Object} return value from invoking the passed function. Please note,
+ when called within an existing loop, no return value is possible.
+ @since 1.4.0
+ */

+ var args = slice.call(arguments);

+ return run.join.apply(run, args.concat(slice.call(arguments)));
+ };
+ };
- The example below shows a simple object that implement the `Ember.Freezable`
- protocol.

+ run.queues = backburner.queueNames;
+
+ /**
+ Begins a new RunLoop. Any deferred actions invoked after the begin will

- firstName: null,

- // swaps the names
- swapNames: function() {
- if (this.get('isFrozen')) throw Ember.FROZEN_ERROR;
- var tmp = this.get('firstName');
- this.set('firstName', this.get('lastName'));
- this.set('lastName', tmp);
- return this;

- ## Using `get()` and `set()`
+ function Meta(obj) {
+ this.descs = {};
+ this.watching = {};
+ this.cache = {};
+ this.cacheMeta = {};
+ this.source = obj;
+ }
- Because of Ember's support for bindings and observers, you will always
- access properties using the get method, and set properties using the
- set method. This allows the observing objects to be notified and
- computed properties to be handled properly.
+ Meta.prototype = {
+ descs: null,
+ deps: null,
+ watching: null,
+ listeners: null,
+ cache: null,
+ cacheMeta: null,
+ source: null,
+ mixins: null,
+ bindings: null,
+ chains: null,
+ chainWatchers: null,
+ values: null,
+ proto: null
+ };
- More documentation about `get` and `set` are below.
+ if (!canDefineNonEnumerableProperties) {
+ // on platforms that don't support enumerable false
+ // make meta fail jQuery.isPlainObject() to hide from
+ // jQuery.extend() by having a property that fails
+ // hasOwnProperty check.
+ Meta.prototype.__preventPlainObject__ = true;
- ## Observing Property Changes
+ // Without non-enumerable properties, meta objects will be output in JSON
+ // unless explicitly suppressed
+ Meta.prototype.toJSON = function () { };
+ }
- You typically observe property changes simply by adding the `observes`
- call to the end of your method declarations in classes that you write.
- For example:
+ // Placeholder for non-writable metas.
+ var EMPTY_META = new Meta(null);
- ```javascript
- Ember.Object.extend({
- valueObserver: function() {
- // Executes whenever the "value" property changes
- }.observes('value')
- });
- ```
+
+ if (hasPropertyAccessors) {
+ EMPTY_META.values = {};
+ }
+
- Although this is the most common way to add an observer, this capability
- is actually built into the `Ember.Object` class on top of two methods
- defined in this mixin: `addObserver` and `removeObserver`. You can use
- these two methods to add and remove observers yourself if you need to

+ interaction to the template's controller or specified `target` option.
- actionContextObject: computed(function() {

+ If the controller does not implement the specified action, the event is sent

- /**
- Send an `action` with an `actionContext` to a `target`. The action, actionContext
- and target will be retrieved from properties of the object. For example:
- ```javascript
- App.SaveButtonView = Ember.View.extend(Ember.TargetActionSupport, {
- target: Ember.computed.alias('controller'),
- action: 'save',
- actionContext: Ember.computed.alias('context'),
- click: function() {
- this.triggerAction(); // Sends the `save` action, along with the current context
- // to the current controller
- }
- });
+ ### Use
+ Given the following application Handlebars template on the page
+
+ ```handlebars
+ <div {{action 'anActionName'}}>
+ click me
+ </div>
```
- The `target`, `action`, and `actionContext` can be provided as properties of
- an optional object argument to `triggerAction` as well.
+ And application code
```javascript
- App.SaveButtonView = Ember.View.extend(Ember.TargetActionSupport, {
- click: function() {
- this.triggerAction({
- action: 'save',
- target: this.get('controller'),
- actionContext: this.get('context'),
- }); // Sends the `save` action, along with the current context
- // to the current controller
+ App.ApplicationController = Ember.Controller.extend({
+ actions: {
+ anActionName: function() {
+ }
}
});
```
- The `actionContext` defaults to the object you mixing `TargetActionSupport` into.
- But `target` and `action` must be specified either as properties or with the argument
- to `triggerAction`, or a combination:
+ Will result in the following rendered HTML
- ```javascript
- App.SaveButtonView = Ember.View.extend(Ember.TargetActionSupport, {
- target: Ember.computed.alias('controller'),
- click: function() {
- this.triggerAction({
- action: 'save'
- }); // Sends the `save` action, along with a reference to `this`,
- // to the current controller
- }
- });
+ ```html
+ <div class="ember-view">
+ <div data-ember-action="1">
+ click me
+ </div>
+ </div>
```
- @method triggerAction
- @param opts {Hash} (optional, with the optional keys action, target and/or actionContext)
- @return {Boolean} true if the action was sent successfully and did not return false
- */
- triggerAction: function(opts) {
- opts = opts || {};
- var action = opts.action || get(this, 'action'),
- target = opts.target || get(this, 'targetObject'),
- actionContext = opts.actionContext;
+ Clicking "click me" will trigger the `anActionName` action of the
+ `App.ApplicationController`. In this case, no additional parameters will be passed.
- function args(options, actionName) {
- var ret = [];
- if (actionName) { ret.push(actionName); }
+ If you provide additional parameters to the helper:
- return ret.concat(options);
- }
+ ```handlebars
+ <button {{action 'edit' post}}>Edit</button>
+ ```
- if (typeof actionContext === 'undefined') {
- actionContext = get(this, 'actionContextObject') || this;
- }
+ Those parameters will be passed along as arguments to the JavaScript
+ function implementing the action.
- if (target && action) {
- var ret;
+ ### Event Propagation
- if (target.send) {
- ret = target.send.apply(target, args(actionContext, action));
- } else {
- Ember.assert("The action '" + action + "' did not exist on " + target, typeof target[action] === 'function');
- ret = target[action].apply(target, args(actionContext));
- }
+ Events triggered through the action helper will automatically have
+ `.preventDefault()` called on them. You do not need to do so in your event
+ handlers. If you need to allow event propagation (to handle file inputs for
+ example) you can supply the `preventDefault=false` option to the `{{action}}` helper:
- if (ret !== false) ret = true;
+ ```handlebars
+ <div {{action "sayHello" preventDefault=false}}>
+ <input type="file" />
+ <input type="checkbox" />
+ </div>
+ ```
- return ret;
- } else {
- return false;
- }
- }
- });
+ To disable bubbling, pass `bubbles=false` to the helper:
- __exports__["default"] = TargetActionSupport;
- });

+ ### Specifying DOM event type
- var OUT_OF_RANGE_EXCEPTION = "Index out of range";
- var EMPTY = [];
- var alias = computed.alias;
- var K = Ember.K;
+ By default the `{{action}}` helper registers for DOM `click` events. You can
+ supply an `on` option to the helper to specify a different DOM event name:
- /**
- An ArrayProxy wraps any other object that implements `Ember.Array` and/or
- `Ember.MutableArray,` forwarding all requests. This makes it very useful for
- a number of binding use cases or other cases where being able to swap
- out the underlying array is useful.
+ ```handlebars
+ <div {{action "anActionName" on="doubleClick"}}>
+ click me
+ </div>
+ ```
- A simple example of usage:
+ See `Ember.View` 'Responding to Browser Events' for a list of
+ acceptable DOM event names.
- ```javascript
- var pets = ['dog', 'cat', 'fish'];
- var ap = Ember.ArrayProxy.create({ content: Ember.A(pets) });
+ ### Specifying whitelisted modifier keys
- ap.get('firstObject'); // 'dog'
- ap.set('content', ['amoeba', 'paramecium']);
- ap.get('firstObject'); // 'amoeba'
+ By default the `{{action}}` helper will ignore click event with pressed modifier
+ keys. You can supply an `allowedKeys` option to specify which keys should not be ignored.
+
+ ```handlebars
+ <div {{action "anActionName" allowedKeys="alt"}}>
+ click me
+ </div>
```
- This class can also be useful as a layer to transform the contents of
- an array, as they are accessed. This can be done by overriding
- `objectAtContent`:
+ This way the `{{action}}` will fire when clicking with the alt key pressed down.
- ```javascript
- var pets = ['dog', 'cat', 'fish'];
- var ap = Ember.ArrayProxy.create({
- content: Ember.A(pets),
- objectAtContent: function(idx) {
- return this.get('content').objectAt(idx).toUpperCase();
- }
- });
+ Alternatively, supply "any" to the `allowedKeys` option to accept any combination of modifier keys.
- ap.get('firstObject'); // . 'DOG'
+ ```handlebars
+ <div {{action "anActionName" allowedKeys="any"}}>
+ click me with any key pressed
+ </div>
```
- @class ArrayProxy
- @namespace Ember
- @extends Ember.Object
- @uses Ember.MutableArray
- */
- var ArrayProxy = EmberObject.extend(MutableArray, {
-
- /**
- The content array. Must be an object that implements `Ember.Array` and/or
- `Ember.MutableArray.`
+ ### Specifying a Target
- @property content
- @type Ember.Array
- */
- content: null,
+ There are several possible target objects for `{{action}}` helpers:
- /**

- implementation, this and `content` are the same. Subclasses of `ArrayProxy`
- can override this property to provide things like sorting and filtering.
+ In a typical Ember application, where templates are managed through use of the
+ `{{outlet}}` helper, actions will bubble to the current controller, then
+ to the current route, and then up the route hierarchy.
- @property arrangedContent
- */
- arrangedContent: alias('content'),
+ Alternatively, a `target` option can be provided to the helper to change
+ which object will receive the method call. This option must be a path
+ to an object, accessible in the current context:
- /**

- content. You can override this method in subclasses to transform the

- value with the subclass' value. An example of this in use within Ember
- is the `classNames` property of `Ember.View`.
+ if (href.indexOf('#') === 0) {

- someNonConcatenatedProperty: ['bar'],
- classNames: ['bar']

- var fooBarView = App.FooBarView.create();

- fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo']
+ ```hbs
+ {{link-to a b '123' c}}
```
- This behavior extends to object creation as well. Continuing the
- above example:
-
- ```javascript
- var view = App.FooBarView.create({
- someNonConcatenatedProperty: ['baz'],
- classNames: ['baz']
- })
- view.get('someNonConcatenatedProperty'); // ['baz']
- view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
- ```
- Adding a single property that is not an array will just add it in the array:
+ will generate a `resolvedParams` of:
- ```javascript
- var view = App.FooBarView.create({
- classNames: 'baz'
- })
- view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
+ ```js
+ [aObject, bObject, '123', cObject]
```
- Using the `concatenatedProperties` property, we can tell to Ember that mix
- the content of the properties.
-
- In `Ember.View` the `classNameBindings` and `attributeBindings` properties
- are also concatenated, in addition to `classNames`.

+ ### Supplying a tagName
+ By default `{{link-to}}` renders an `<a>` element. This can
+ be overridden for a single use of `{{link-to}}` by supplying
+ a `tagName` option:
- CoreObject.PrototypeMixin.ownerConstructor = CoreObject;
+ ```handlebars
+ {{#link-to 'photoGallery' tagName="li"}}
+ Great Hamster Photos
+ {{/link-to}}
+ ```
- function makeToString(ret) {
- return function() { return ret; };
- }
+ ```html
+ <li>
+ Great Hamster Photos
+ </li>
+ ```
- if (Ember.config.overridePrototypeMixin) {
- Ember.config.overridePrototypeMixin(CoreObject.PrototypeMixin);
- }
+ To override this option for your entire application, see
+ "Overriding Application-wide Defaults".
- CoreObject.__super__ = null;
+ ### Disabling the `link-to` helper
+ By default `{{link-to}}` is enabled.
+ any passed value to `disabled` helper property will disable the `link-to` helper.
- var ClassMixin = Mixin.create({
+ static use: the `disabled` option:
- ClassMixin: required(),
+ ```handlebars
+ {{#link-to 'photoGallery' disabled=true}}
+ Great Hamster Photos
+ {{/link-to}}
+ ```
- PrototypeMixin: required(),
+ dynamic use: the `disabledWhen` option:
- isClass: true,
+ ```handlebars
+ {{#link-to 'photoGallery' disabledWhen=controller.someProperty}}
+ Great Hamster Photos
+ {{/link-to}}
+ ```
- isMethod: false,
+ any passed value to `disabled` will disable it except `undefined`.
+ to ensure that only `true` disable the `link-to` helper you can
+ override the global behaviour of `Ember.LinkView`.
- /**
- Creates a new subclass.
+ ```javascript
+ Ember.LinkView.reopen({
+ disabled: Ember.computed(function(key, value) {
+ if (value !== undefined) {
+ this.set('_isDisabled', value === true);
+ }
+ return value === true ? get(this, 'disabledClass') : false;
+ })
+ });
+ ```
- ```javascript
- App.Person = Ember.Object.extend({
- say: function(thing) {
- alert(thing);
- }
- });
- ```
+ see "Overriding Application-wide Defaults" for more.
- This defines a new subclass of Ember.Object: `App.Person`. It contains one method: `say()`.
+ ### Handling `href`
+ `{{link-to}}` will use your application's Router to
+ fill the element's `href` property with a url that
+ matches the path to the supplied `routeName` for your
+ routers's configured `Location` scheme, which defaults
+ to Ember.HashLocation.
- You can also create a subclass from any existing class by calling its `extend()` method. For example, you might want to create a subclass of Ember's built-in `Ember.View` class:
+ ### Handling current route
+ `{{link-to}}` will apply a CSS class name of 'active'
+ when the application's current route matches
+ the supplied routeName. For example, if the application's
+ current route is 'photoGallery.recent' the following
+ use of `{{link-to}}`:
- ```javascript
- App.PersonView = Ember.View.extend({
- tagName: 'li',
- classNameBindings: ['isAdministrator']
- });
- ```
+ ```handlebars
+ {{#link-to 'photoGallery.recent'}}
+ Great Hamster Photos from the last week
+ {{/link-to}}
+ ```
- When defining a subclass, you can override methods but still access the implementation of your parent class by calling the special `_super()` method:
+ will result in
- ```javascript
- App.Person = Ember.Object.extend({
- say: function(thing) {
- var name = this.get('name');
- alert(name + ' says: ' + thing);
- }
- });
+ ```html
+ <a href="/hamster-photos/this-week" class="active">
+ Great Hamster Photos
+ </a>
+ ```
- App.Soldier = App.Person.extend({
- say: function(thing) {
- this._super(thing + ", sir!");
- },
- march: function(numberOfHours) {
- alert(this.get('name') + ' marches for ' + numberOfHours + ' hours.')
- }
- });
+ The CSS class name used for active classes can be customized
+ for a single use of `{{link-to}}` by passing an `activeClass`
+ option:
- var yehuda = App.Soldier.create({
- name: "Yehuda Katz"
- });
+ ```handlebars
+ {{#link-to 'photoGallery.recent' activeClass="current-url"}}
+ Great Hamster Photos from the last week
+ {{/link-to}}
+ ```
- yehuda.say("Yes"); // alerts "Yehuda Katz says: Yes, sir!"
- ```
+ ```html
+ <a href="/hamster-photos/this-week" class="current-url">
+ Great Hamster Photos
+ </a>
+ ```
- The `create()` on line #17 creates an *instance* of the `App.Soldier` class. The `extend()` on line #8 creates a *subclass* of `App.Person`. Any instance of the `App.Person` class will *not* have the `march()` method.
+ To override this option for your entire application, see
+ "Overriding Application-wide Defaults".
- You can also pass `Mixin` classes to add additional properties to the subclass.
+ ### Supplying a model
+ An optional model argument can be used for routes whose
+ paths contain dynamic segments. This argument will become
+ the model context of the linked route:
- ```javascript
- App.Person = Ember.Object.extend({
- say: function(thing) {
- alert(this.get('name') + ' says: ' + thing);
- }
- });
+ ```javascript
+ App.Router.map(function() {
+ this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
+ });
+ ```
- App.SingingMixin = Mixin.create({
- sing: function(thing){
- alert(this.get('name') + ' sings: la la la ' + thing);
- }
- });
+ ```handlebars
+ {{#link-to 'photoGallery' aPhoto}}
+ {{aPhoto.title}}
+ {{/link-to}}
+ ```
- App.BroadwayStar = App.Person.extend(App.SingingMixin, {
- dance: function() {
- alert(this.get('name') + ' dances: tap tap tap tap ');
- }
+ ```html
+ <a href="/hamster-photos/42">
+ Tomster
+ </a>
+ ```
+
+ ### Supplying multiple models
+ For deep-linking to route paths that contain multiple
+ dynamic segments, multiple model arguments can be used.
+ As the router transitions through the route path, each
+ supplied model argument will become the context for the
+ route with the dynamic segments:
+
+ ```javascript
+ App.Router.map(function() {
+ this.resource("photoGallery", {path: "hamster-photos/:photo_id"}, function() {
+ this.route("comment", {path: "comments/:comment_id"});
});
- ```
+ });
+ ```
+ This argument will become the model context of the linked route:
- The `App.BroadwayStar` class contains three methods: `say()`, `sing()`, and `dance()`.
+ ```handlebars
+ {{#link-to 'photoGallery.comment' aPhoto comment}}
+ {{comment.body}}
+ {{/link-to}}
+ ```
- @method extend
- @static
+ ```html
+ <a href="/hamster-photos/42/comment/718">
+ A+++ would snuggle again.
+ </a>
+ ```
- @param {Mixin} [mixins]* One or more Mixin classes
- @param {Object} [arguments]* Object containing values to use within the new class
- */
- extend: function() {
- var Class = makeCtor(), proto;
- Class.ClassMixin = Mixin.create(this.ClassMixin);
- Class.PrototypeMixin = Mixin.create(this.PrototypeMixin);
+ ### Supplying an explicit dynamic segment value
+ If you don't have a model object available to pass to `{{link-to}}`,
+ an optional string or integer argument can be passed for routes whose
+ paths contain dynamic segments. This argument will become the value
+ of the dynamic segment:
- Class.ClassMixin.ownerConstructor = Class;
- Class.PrototypeMixin.ownerConstructor = Class;
+ ```javascript
+ App.Router.map(function() {
+ this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
+ });
+ ```
- reopen.apply(Class.PrototypeMixin, arguments);
+ ```handlebars
+ {{#link-to 'photoGallery' aPhotoId}}
+ {{aPhoto.title}}
+ {{/link-to}}
+ ```
- Class.superclass = this;
- Class.__super__ = this.prototype;
+ ```html
+ <a href="/hamster-photos/42">
+ Tomster
+ </a>
+ ```
- proto = Class.prototype = o_create(this.prototype);
- proto.constructor = Class;
- generateGuid(proto);
- meta(proto).proto = proto; // this will disable observers on prototype
+ When transitioning into the linked route, the `model` hook will
+ be triggered with parameters including this passed identifier.
- Class.ClassMixin.apply(Class);
- return Class;
- },
+ ### Allowing Default Action
- /**
- Equivalent to doing `extend(arguments).create()`.
- If possible use the normal `create` method instead.
+ By default the `{{link-to}}` helper prevents the default browser action
+ by calling `preventDefault()` as this sort of action bubbling is normally
+ handled internally and we do not want to take the browser to a new URL (for
+ example).
- @method createWithMixins
- @static
- @param [arguments]*
- */
- createWithMixins: function() {
- var C = this;
- if (arguments.length>0) { this._initMixins(arguments); }
- return new C();
- },
+ If you need to override this behavior specify `preventDefault=false` in
+ your template:
- /**
- Creates an instance of a class. Accepts either no arguments, or an object
- containing values to initialize the newly instantiated object with.
+ ```handlebars
+ {{#link-to 'photoGallery' aPhotoId preventDefault=false}}
+ {{aPhotoId.title}}
+ {{/link-to}}
+ ```
- ```javascript
- App.Person = Ember.Object.extend({
- helloWorld: function() {
- alert("Hi, my name is " + this.get('name'));
- }
- });
+ ### Overriding attributes
+ You can override any given property of the Ember.LinkView
+ that is generated by the `{{link-to}}` helper by passing
+ key/value pairs, like so:
- var tom = App.Person.create({
- name: 'Tom Dale'
- });
+ ```handlebars
+ {{#link-to aPhoto tagName='li' title='Following this link will change your life' classNames='pic sweet'}}
+ Uh-mazing!
+ {{/link-to}}
+ ```
- tom.helloWorld(); // alerts "Hi, my name is Tom Dale".
- ```
+ See [Ember.LinkView](/api/classes/Ember.LinkView.html) for a
+ complete list of overrideable properties. Be sure to also
+ check out inherited properties of `LinkView`.
- `create` will call the `init` function if defined during
- `Ember.AnyObject.extend`
+ ### Overriding Application-wide Defaults
+ ``{{link-to}}`` creates an instance of Ember.LinkView
+ for rendering. To override options for your entire
+ application, reopen Ember.LinkView and supply the
+ desired values:
- If no arguments are passed to `create`, it will not set values to the new
- instance during initialization:
+ ``` javascript
+ Ember.LinkView.reopen({
+ activeClass: "is-active",
+ tagName: 'li'
+ })
+ ```
- ```javascript
- var noName = App.Person.create();
- noName.helloWorld(); // alerts undefined
- ```
+ It is also possible to override the default event in
+ this manner:
- NOTE: For performance reasons, you cannot declare methods or computed
- properties during `create`. You should instead declare methods and computed
- properties when using `extend` or use the `createWithMixins` shorthand.
+ ``` javascript
+ Ember.LinkView.reopen({
+ eventName: 'customEventName'
+ });
+ ```

+ By default, a template based on Ember's naming conventions will be rendered
+ into the `outlet` (e.g. `App.PostsRoute` will render the `posts` template).
+
+ You can render a different template by using the `render()` method in the
+ route's `renderTemplate` hook. The following will render the `favoritePost`
+ template into the `outlet`.
+
+ ``` javascript
+ App.PostsRoute = Ember.Route.extend({
+ renderTemplate: function() {
+ this.render('favoritePost');
}
- return false;

- In some cases, you may want to annotate computed properties with additional
- metadata about how they function or what values they operate on. For
- example, computed property functions may close over variables that are then
- no longer available for introspection.
+ ``` handlebars
+ {{outlet 'favoritePost'}}
+ {{outlet 'posts'}}
+ ```
- You can pass a hash of these values to a computed property like this:
+ Then you can define what template is rendered into each outlet in your
+ route.
- ```javascript
- person: function() {
- var personId = this.get('personId');
- return App.Person.create({ id: personId });
- }.property().meta({ type: App.Person })
- ```
- Once you've done this, you can retrieve the values saved to the computed
- property from your class like this:
+ ``` javascript
+ App.PostsRoute = Ember.Route.extend({
+ renderTemplate: function() {
+ this.render('favoritePost', { outlet: 'favoritePost' });
+ this.render('posts', { outlet: 'posts' });
+ }
+ });
+ ```
- ```javascript
- MyClass.metaForProperty('person');
- ```
+ You can specify the view that the outlet uses to contain and manage the
+ templates rendered into it.
- This will return the original hash that was passed to `meta()`.
+ ``` handlebars
+ {{outlet view='sectionContainer'}}

+ Using `HashLocation` results in URLs with a `#` (hash sign) separating the

+ This relies upon the `hashchange` event existing in the browser.
- /**
- `Ember.ObjectProxy` forwards all properties not defined by the proxy itself
- to a proxied `content` object.
+ Example:
```javascript
- object = Ember.Object.create({
- name: 'Foo'
+ App.Router.map(function() {
+ this.resource('posts', function() {
+ this.route('new');
+ });
});
- proxy = Ember.ObjectProxy.create({

+ App.Router.reopen({
+ location: 'hash'
});
+ ```
- // Access and change existing properties
- proxy.get('name') // 'Foo'
- proxy.set('name', 'Bar');
- object.get('name') // 'Bar'
+ This will result in a posts.new url of `/#/posts/new`.
- // Create new 'description' property on `object`
- proxy.set('description', 'Foo is a whizboo baz');
- object.get('description') // 'Foo is a whizboo baz'
- ```
+ ### HistoryLocation
- While `content` is unset, setting a property to be delegated will throw an
- Error.
+ Using `HistoryLocation` results in URLs that are indistinguishable from a
+ standard URL. This relies upon the browser's `history` API.
+
+ Example:
```javascript
- proxy = Ember.ObjectProxy.create({
- content: null,
- flag: null
+ App.Router.map(function() {
+ this.resource('posts', function() {
+ this.route('new');
+ });
});
- proxy.set('flag', true);
- proxy.get('flag'); // true
- proxy.get('foo'); // undefined
- proxy.set('foo', 'data'); // throws Error
- ```
- Delegated properties can be bound to and will change when content is updated.
+ App.Router.reopen({
+ location: 'history'
+ });
+ ```
- Computed properties on the proxy itself can depend on delegated properties.
+ This will result in a posts.new url of `/posts/new`.
- ```javascript
- ProxyWithComputedProperty = Ember.ObjectProxy.extend({
- fullName: function () {
- var firstName = this.get('firstName'),
- lastName = this.get('lastName');
- if (firstName && lastName) {
- return firstName + ' ' + lastName;
- }
- return firstName || lastName;
- }.property('firstName', 'lastName')
- });
+ Keep in mind that your server must serve the Ember app at all the routes you
+ define.
- proxy = ProxyWithComputedProperty.create();
+ ### AutoLocation
- proxy.get('fullName'); // undefined
- proxy.set('content', {
- firstName: 'Tom', lastName: 'Dale'
- }); // triggers property change for fullName on proxy
+ Using `AutoLocation`, the router will use the best Location class supported by
+ the browser it is running in.
- proxy.get('fullName'); // 'Tom Dale'
- ```
+ Browsers that support the `history` API will use `HistoryLocation`, those that
+ do not, but still support the `hashchange` event will use `HashLocation`, and
+ in the rare case neither is supported will use `NoneLocation`.

- `Ember.Set` primary implements other mixin APIs. For a complete reference
- on the methods you will use with `Ember.Set`, please consult these mixins.
- The most useful ones will be `Ember.Enumerable` and
- `Ember.MutableEnumerable` which implement most of the common iterator
- methods you are used to on Array.
+ Clean pushState paths accessed by hashchange-only browsers will be redirected
+ to the hash-equivalent and vice versa so future transitions are consistent.
- Note that you can also use the `Ember.Copyable` and `Ember.Freezable`
- APIs on `Ember.Set` as well. Once a set is frozen it can no longer be
- modified. The benefit of this is that when you call `frozenCopy()` on it,
- Ember will avoid making copies of the set. This allows you to write
- code that can know with certainty when the underlying set data will or
- will not be modified.

+ /**
+ `render` is used to render a template into a region of another template
+ (indicated by an `{{outlet}}`). `render` is used both during the entry
+ phase of routing (via the `renderTemplate` hook) and later in response to
+ user interaction.
- ## Automatic matching of parent/child tagNames
+ For example, given the following minimal router and templates:
- Setting the `tagName` property of a `CollectionView` to any of
- "ul", "ol", "table", "thead", "tbody", "tfoot", "tr", or "select" will result
- in the item views receiving an appropriately matched `tagName` property.
+ ```js
+ Router.map(function() {
+ this.resource('photos');
+ });
+ ```
- Given an empty `<body>` and the following code:
+ ```handlebars
+ <!-- application.hbs -->
+ <div class='something-in-the-app-hbs'>
+ {{outlet "anOutletName"}}
+ </div>
+ ```
- ```javascript
- anUnorderedListView = Ember.CollectionView.create({
- tagName: 'ul',
- content: ['A','B','C'],
- itemViewClass: Ember.View.extend({
- template: Ember.Handlebars.compile("the letter: {{view.content}}")
- })
- });
+ ```handlebars
+ <!-- photos.hbs -->
+ <h1>Photos</h1>
+ ```
- anUnorderedListView.appendTo('body');
- ```
+ You can render `photos.hbs` into the `"anOutletName"` outlet of
+ `application.hbs` by calling `render`:
- Will result in the following HTML structure
+ ```js
+ // posts route
+ Ember.Route.extend({
+ renderTemplate: function(){
+ this.render('photos', {
+ into: 'application',
+ outlet: 'anOutletName'
+ })
+ }
+ });
+ ```
- ```html
- <ul class="ember-view a-collection">
- <li class="ember-view">the letter: A</li>
- <li class="ember-view">the letter: B</li>
- <li class="ember-view">the letter: C</li>
- </ul>
- ```
+ `render` additionally allows you to supply which `view`, `controller`, and
+ `model` objects should be loaded and associated with the rendered template.
- Additional `tagName` pairs can be provided by adding to
- `Ember.CollectionView.CONTAINER_MAP `
- ```javascript
- Ember.CollectionView.CONTAINER_MAP['article'] = 'section'
- ```
+ ```js
+ // posts route
+ Ember.Route.extend({
+ renderTemplate: function(controller, model){
+ this.render('posts', { // the template to render, referenced by name
+ into: 'application', // the template to render into, referenced by name
+ outlet: 'anOutletName', // the outlet inside `options.template` to render into.
+ view: 'aViewName', // the view to use for this template, referenced by name
+ controller: 'someControllerName', // the controller to use for this template, referenced by name
+ model: model // the model to set on `options.controller`.
+ })
+ }
+ });
+ ```
- ## Programmatic creation of child views
+ The string values provided for the template name, view, and controller
+ will eventually pass through to the resolver for lookup. See
+ Ember.Resolver for how these are mapped to JavaScript objects in your
+ application.
- For cases where additional customization beyond the use of a single
- `itemViewClass` or `tagName` matching is required CollectionView's
- `createChildView` method can be overidden:
+ Not all options need to be passed to `render`. Default values will be used
+ based on the name of the route specified in the router or the Route's
+ `controllerName`, `viewName` and and `templateName` properties.
- ```javascript
- CustomCollectionView = Ember.CollectionView.extend({
- createChildView: function(viewClass, attrs) {
- if (attrs.content.kind == 'album') {
- viewClass = App.AlbumView;
- } else {
- viewClass = App.SongView;
+ For example:
+
+ ```js
+ // router
+ Router.map(function() {
+ this.route('index');
+ this.resource('post', {path: '/posts/:post_id'});
+ });
+ ```
+
+ ```js
+ // post route
+ PostRoute = App.Route.extend({
+ renderTemplate: function() {
+ this.render(); // all defaults apply
}
- return this._super(viewClass, attrs);
- }
- });
- ```
+ });
+ ```
- ## Empty View
+ The name of the `PostRoute`, defined by the router, is `post`.
- You can provide an `Ember.View` subclass to the `Ember.CollectionView`
- instance as its `emptyView` property. If the `content` property of a
- `CollectionView` is set to `null` or an empty array, an instance of this view
- will be the `CollectionView`s only child.
+ The following equivalent default options will be applied when
+ the Route calls `render`:
- ```javascript
- aListWithNothing = Ember.CollectionView.create({
- classNames: ['nothing']
- content: null,
- emptyView: Ember.View.extend({
- template: Ember.Handlebars.compile("The collection is empty")
+ ```js
+ //
+ this.render('post', { // the template name associated with 'post' Route
+ into: 'application', // the parent route to 'post' Route
+ outlet: 'main', // {{outlet}} and {{outlet 'main' are synonymous}},
+ view: 'post', // the view associated with the 'post' Route
+ controller: 'post', // the controller associated with the 'post' Route
})
- });
+ ```
- aListWithNothing.appendTo('body');
- ```
+ By default the controller's `model` will be the route's model, so it does not
+ need to be passed unless you wish to change which model is being used.
- Will result in the following HTML structure
+ @method render
+ @param {String} name the name of the template to render
+ @param {Object} [options] the options
+ @param {String} [options.into] the template to render into,
+ referenced by name. Defaults to the parent template
+ @param {String} [options.outlet] the outlet inside `options.template` to render into.
+ Defaults to 'main'
+ @param {String} [options.controller] the controller to use for this template,
+ referenced by name. Defaults to the Route's paired controller
+ @param {String} [options.model] the model object to set on `options.controller`
+ Defaults to the return value of the Route's model hook

- An `Ember.Component` is a view that is completely
- isolated. Property access in its templates go
- to the view object and actions are targeted at
- the view object. There is no access to the
- surrounding context or outer controller; all
- contextual information must be passed in.
-
- The easiest way to create an `Ember.Component` is via
- a template. If you name a template
- `components/my-foo`, you will be able to use
- `{{my-foo}}` in other templates, which will make
- an instance of the isolated component.
-
- ```handlebars
- {{app-profile person=currentUser}}
- ```
-
- ```handlebars
- <!-- app-profile template -->
- <h1>{{person.title}}</h1>
- <img {{bind-attr src=person.avatar}}>
- <p class='signature'>{{person.signature}}</p>
- ```
-
- You can use `yield` inside a template to
- include the **contents** of any block attached to
- the component. The block will be executed in the
- context of the surrounding context or outer controller:
-
- ```handlebars
- {{#app-profile person=currentUser}}
- <p>Admin mode</p>
- {{! Executed in the controller's context. }}
- {{/app-profile}}
- ```
+ // // side effect of loading some Ember globals, for now
+ // requireModule("ember-handlebars");
+ // requireModule("ember-runtime");

- ## Setting Initial Child Views
+ if (rootURL && this.container && !this.container.has('-location-setting:root-url')) {
+ this.container.register('-location-setting:root-url', rootURL, { instantiate: false });
+ }
- The initial array of child views can be set in one of two ways. You can
- provide a `childViews` property at creation time that contains instance of
- `Ember.View`:
+ if ('string' === typeof location && this.container) {
+ var resolvedLocation = this.container.lookup('location:' + location);
- ```javascript

- ```
+ if ('undefined' !== typeof resolvedLocation) {

+ } else {
+ // Allow for deprecated registration of custom location API's
+ var options = {implementation: location};
- You can also provide a list of property names whose values are instances of
- `Ember.View`:
+ location = set(this, 'location', EmberLocation.create(options));
+ }
+ }
- ```javascript
- aContainer = Ember.ContainerView.create({
- childViews: ['aView', 'bView', 'cView'],
- aView: Ember.View.create(),
- bView: Ember.View.create(),
- cView: Ember.View.create()
- });
- ```
+ if (location !== null && typeof location === 'object') {
+ if (rootURL && typeof rootURL === 'string') {
+ location.rootURL = rootURL;
+ }
- The two strategies can be combined:
+ // ensure that initState is called AFTER the rootURL is set on
+ // the location instance
+ if (typeof location.initState === 'function') {
+ location.initState();
+ }
+ }
+ },
- ```javascript
- aContainer = Ember.ContainerView.create({

- HTML in the same order as its position in the `childViews` property.
+ return function(name) {
+ var routeName = 'route:' + name;
+ var handler = container.lookup(routeName);
- ## Adding and Removing Child Views
+ if (seen[name]) { return handler; }
- The container view implements `Ember.MutableArray` allowing programmatic management of its child views.
+ seen[name] = true;
- To remove a view, pass that view into a `removeObject` call on the container view.

+ The `removedItem` and `addedItem` functions should return the accumulated

+ dependentArrayWillChange: function (dependentArray, index, removedCount, addedCount) {
+ if (this.suspended) { return; }
- ## HTML Tag
+ var removedItem = this.callbacks.removedItem;
+ var changeMeta;
+ var guid = guidFor(dependentArray);
+ var dependentKey = this.dependentKeysByGuid[guid];
+ var itemPropertyKeys = this.cp._itemPropertyKeys[dependentKey] || [];

+ var normalizedIndex = normalizeIndex(index, length, 0);
+ var normalizedRemoveCount = normalizeRemoveCount(normalizedIndex, length, removedCount);
+ var item, itemIndex, sliceIndex, observerContexts;
- The default HTML tag name used for a view's DOM representation is `div`. This
- can be customized by setting the `tagName` property. The following view
- class:
+ observerContexts = this.trackRemove(dependentKey, normalizedIndex, normalizedRemoveCount);
- ```javascript
- ParagraphView = Ember.View.extend({
- tagName: 'em'
- });
- ```
+ function removeObservers(propertyKey) {
+ observerContexts[sliceIndex].destroyed = true;
+ removeBeforeObserver(item, propertyKey, this, observerContexts[sliceIndex].beforeObserver);
+ removeObserver(item, propertyKey, this, observerContexts[sliceIndex].observer);
+ }
- Would result in instances with the following HTML:
+ for (sliceIndex = normalizedRemoveCount - 1; sliceIndex >= 0; --sliceIndex) {
+ itemIndex = normalizedIndex + sliceIndex;
+ if (itemIndex >= length) { break; }
- ```html
- <em id="ember1" class="ember-view"></em>
- ```
+ item = dependentArray.objectAt(itemIndex);
- ## HTML `class` Attribute
+ forEach(itemPropertyKeys, removeObservers, this);
- The HTML `class` attribute of a view's tag can be set by providing a
- `classNames` property that is set to an array of strings:
+ changeMeta = new ChangeMeta(dependentArray, item, itemIndex, this.instanceMeta.propertyName, this.cp, normalizedRemoveCount);
+ this.setValue(removedItem.call(
+ this.instanceMeta.context, this.getValue(), item, changeMeta, this.instanceMeta.sugarMeta));
+ }
+ this.callbacks.flushedChanges.call(this.instanceMeta.context, this.getValue(), this.instanceMeta.sugarMeta);
+ },
- ```javascript
- MyView = Ember.View.extend({
- classNames: ['my-class', 'my-other-class']
- });
- ```
+ dependentArrayDidChange: function (dependentArray, index, removedCount, addedCount) {
+ if (this.suspended) { return; }
- Will result in view instances with an HTML representation of:
+ var addedItem = this.callbacks.addedItem;
+ var guid = guidFor(dependentArray);
+ var dependentKey = this.dependentKeysByGuid[guid];
+ var observerContexts = new Array(addedCount);
+ var itemPropertyKeys = this.cp._itemPropertyKeys[dependentKey];
+ var length = get(dependentArray, 'length');
+ var normalizedIndex = normalizeIndex(index, length, addedCount);
+ var endIndex = normalizedIndex + addedCount;
+ var changeMeta, observerContext;
+
+ forEach(dependentArray.slice(normalizedIndex, endIndex), function (item, sliceIndex) {
+ if (itemPropertyKeys) {
+ observerContext = this.createPropertyObserverContext(dependentArray, normalizedIndex + sliceIndex,
+ this.trackedArraysByGuid[dependentKey]);
+ observerContexts[sliceIndex] = observerContext;
- ```html
- <div id="ember1" class="ember-view my-class my-other-class"></div>
- ```
+ forEach(itemPropertyKeys, function (propertyKey) {
+ addBeforeObserver(item, propertyKey, this, observerContext.beforeObserver);
+ addObserver(item, propertyKey, this, observerContext.observer);
+ }, this);
+ }
- `class` attribute values can also be set by providing a `classNameBindings`
- property set to an array of properties names for the view. The return value
- of these properties will be added as part of the value for the view's `class`
- attribute. These properties can be computed properties:
+ changeMeta = new ChangeMeta(dependentArray, item, normalizedIndex + sliceIndex, this.instanceMeta.propertyName, this.cp, addedCount);
+ this.setValue(addedItem.call(
+ this.instanceMeta.context, this.getValue(), item, changeMeta, this.instanceMeta.sugarMeta));
+ }, this);
+ this.callbacks.flushedChanges.call(this.instanceMeta.context, this.getValue(), this.instanceMeta.sugarMeta);
+ this.trackAdd(dependentKey, normalizedIndex, observerContexts);
+ },
- ```javascript
- MyView = Ember.View.extend({
- classNameBindings: ['propertyA', 'propertyB'],
- propertyA: 'from-a',
- propertyB: function() {
- if (someLogic) { return 'from-b'; }
- }.property()
- });
- ```
+ itemPropertyWillChange: function (obj, keyName, array, observerContext) {
+ var guid = guidFor(obj);
- Will result in view instances with an HTML representation of:
+ if (!this.changedItems[guid]) {
+ this.changedItems[guid] = {
+ array: array,
+ observerContext: observerContext,
+ obj: obj,
+ previousValues: {}
+ };
+ }
- ```html
- <div id="ember1" class="ember-view from-a from-b"></div>
- ```
+ ++this.changedItemCount;
+ this.changedItems[guid].previousValues[keyName] = get(obj, keyName);
+ },
- If the value of a class name binding returns a boolean the property name
- itself will be used as the class name if the property is true. The class name
- will not be added if the value is `false` or `undefined`.
+ itemPropertyDidChange: function (obj, keyName, array, observerContext) {
+ if (--this.changedItemCount === 0) {
+ this.flushChanges();
+ }
+ },
- ```javascript
- MyView = Ember.View.extend({
- classNameBindings: ['hovered'],
- hovered: true
- });
- ```
+ flushChanges: function () {
+ var changedItems = this.changedItems;
+ var key, c, changeMeta;
- Will result in view instances with an HTML representation of:
+ for (key in changedItems) {
+ c = changedItems[key];
+ if (c.observerContext.destroyed) { continue; }
- ```html
- <div id="ember1" class="ember-view hovered"></div>
- ```
+ this.updateIndexes(c.observerContext.trackedArray, c.observerContext.dependentArray);
- When using boolean class name bindings you can supply a string value other
- than the property name for use as the `class` HTML attribute by appending the
- preferred value after a ":" character when defining the binding:
+ changeMeta = new ChangeMeta(c.array, c.obj, c.observerContext.index, this.instanceMeta.propertyName, this.cp, changedItems.length, c.previousValues);
+ this.setValue(
+ this.callbacks.removedItem.call(this.instanceMeta.context, this.getValue(), c.obj, changeMeta, this.instanceMeta.sugarMeta));
+ this.setValue(
+ this.callbacks.addedItem.call(this.instanceMeta.context, this.getValue(), c.obj, changeMeta, this.instanceMeta.sugarMeta));
+ }
- ```javascript
- MyView = Ember.View.extend({
- classNameBindings: ['awesome:so-very-cool'],
- awesome: true
- });
- ```
+ this.changedItems = {};
+ this.callbacks.flushedChanges.call(this.instanceMeta.context, this.getValue(), this.instanceMeta.sugarMeta);
+ }
+ };
- Will result in view instances with an HTML representation of:
+ function normalizeIndex(index, length, newItemsOffset) {
+ if (index < 0) {
+ return Math.max(0, length + index);
+ } else if (index < length) {
+ return index;
+ } else /* index > length */ {
+ return Math.min(length - newItemsOffset, index);
+ }
+ }
- ```html
- <div id="ember1" class="ember-view so-very-cool"></div>
- ```
+ function normalizeRemoveCount(index, length, removedCount) {
+ return Math.min(removedCount, length - index);
+ }
- Boolean value class name bindings whose property names are in a
- camelCase-style format will be converted to a dasherized format:
+ function ChangeMeta(dependentArray, item, index, propertyName, property, changedCount, previousValues){
+ this.arrayChanged = dependentArray;
+ this.index = index;
+ this.item = item;
+ this.propertyName = propertyName;
+ this.property = property;
+ this.changedCount = changedCount;
- ```javascript
- MyView = Ember.View.extend({
- classNameBindings: ['isUrgent'],
- isUrgent: true
- });
- ```
+ if (previousValues) {
+ // previous values only available for item property changes
+ this.previousValues = previousValues;
+ }
+ }
- Will result in view instances with an HTML representation of:
+ function addItems(dependentArray, callbacks, cp, propertyName, meta) {
+ forEach(dependentArray, function (item, index) {
+ meta.setValue( callbacks.addedItem.call(
+ this, meta.getValue(), item, new ChangeMeta(dependentArray, item, index, propertyName, cp, dependentArray.length), meta.sugarMeta));
+ }, this);
+ callbacks.flushedChanges.call(this, meta.getValue(), meta.sugarMeta);
+ }
- ```html
- <div id="ember1" class="ember-view is-urgent"></div>
- ```
+ function reset(cp, propertyName) {
+ var callbacks = cp._callbacks();
+ var hadMeta = cp._hasInstanceMeta(this, propertyName);
+ var meta = cp._instanceMeta(this, propertyName);
- Class name bindings can also refer to object values that are found by
- traversing a path relative to the view itself:
+ if (hadMeta) { meta.setValue(cp.resetValue(meta.getValue())); }
- ```javascript
- MyView = Ember.View.extend({
- classNameBindings: ['messages.empty']
- messages: Ember.Object.create({
- empty: true
- })
- });
- ```
+ if (cp.options.initialize) {
+ cp.options.initialize.call(this, meta.getValue(), {
+ property: cp,
+ propertyName: propertyName
+ }, meta.sugarMeta);
+ }
+ }
- Will result in view instances with an HTML representation of:
+ function partiallyRecomputeFor(obj, dependentKey) {
+ if (arrayBracketPattern.test(dependentKey)) {
+ return false;
+ }
- ```html
- <div id="ember1" class="ember-view empty"></div>
- ```
+ var value = get(obj, dependentKey);
+ return EmberArray.detect(value);
+ }
- If you want to add a class name for a property which evaluates to true and
- and a different class name if it evaluates to false, you can pass a binding
- like this:
+ function ReduceComputedPropertyInstanceMeta(context, propertyName, initialValue) {
+ this.context = context;
+ this.propertyName = propertyName;
+ this.cache = metaFor(context).cache;
+ this.dependentArrays = {};
+ this.sugarMeta = {};
+ this.initialValue = initialValue;
+ }
- ```javascript
- // Applies 'enabled' class when isEnabled is true and 'disabled' when isEnabled is false
- Ember.View.extend({
- classNameBindings: ['isEnabled:enabled:disabled']
- isEnabled: true
- });
- ```
+ ReduceComputedPropertyInstanceMeta.prototype = {
+ getValue: function () {
+ var value = cacheGet(this.cache, this.propertyName);
- Will result in view instances with an HTML representation of:
+ if (value !== undefined) {
+ return value;
+ } else {
+ return this.initialValue;
+ }
+ },
- ```html
- <div id="ember1" class="ember-view enabled"></div>
- ```
+ setValue: function(newValue, triggerObservers) {
+ // This lets sugars force a recomputation, handy for very simple
+ // implementations of eg max.
+ if (newValue === cacheGet(this.cache, this.propertyName)) {
+ return;
+ }
- When isEnabled is `false`, the resulting HTML reprensentation looks like
- this:
+ if (triggerObservers) {
+ propertyWillChange(this.context, this.propertyName);
+ }
- ```html
- <div id="ember1" class="ember-view disabled"></div>
- ```
+ if (newValue === undefined) {
+ cacheRemove(this.cache, this.propertyName);
+ } else {
+ cacheSet(this.cache, this.propertyName, newValue);
+ }
- This syntax offers the convenience to add a class if a property is `false`:
+ if (triggerObservers) {
+ propertyDidChange(this.context, this.propertyName);
+ }
+ }
+ };
- ```javascript
- // Applies no class when isEnabled is true and class 'disabled' when isEnabled is false
- Ember.View.extend({
- classNameBindings: ['isEnabled::disabled']
- isEnabled: true
- });
- ```
+ /**
+ A computed property whose dependent keys are arrays and which is updated with
+ "one at a time" semantics.
- Will result in view instances with an HTML representation of:

+ */
- ```html

- ```
+ __exports__.ReduceComputedProperty = ReduceComputedProperty;
+ // TODO: default export

- Updates to the the value of a class name binding will result in automatic
- update of the HTML `class` attribute in the view's rendered HTML
- representation. If the value becomes `false` or `undefined` the class name
- will be removed.

- Both `classNames` and `classNameBindings` are concatenated properties. See

+ var recompute = function(propertyName) {

- The HTML attribute section of a view's tag can be set by providing an
- `attributeBindings` property set to an array of property names on the view.
- The return value of these properties will be used as the value of the view's
- HTML associated attribute:
+ reset.call(this, cp, propertyName);
- ```javascript
- AnchorView = Ember.View.extend({
- tagName: 'a',
- attributeBindings: ['href'],
- href: 'http://google.com'
- });
- ```
+ meta.dependentArraysObserver.suspendArrayObservers(function () {
+ forEach(cp._dependentKeys, function (dependentKey) {
+ Ember.assert(
+ 'dependent array ' + dependentKey + ' must be an `Ember.Array`. ' +
+ 'If you are not extending arrays, you will need to wrap native arrays with `Ember.A`',
+ !(isArray(get(this, dependentKey)) && !EmberArray.detect(get(this, dependentKey))));
- Will result in view instances with an HTML representation of:
+ if (!partiallyRecomputeFor(this, dependentKey)) { return; }
- ```html
- <a id="ember1" class="ember-view" href="http://google.com"></a>
- ```
+ var dependentArray = get(this, dependentKey);
+ var previousDependentArray = meta.dependentArrays[dependentKey];
- If the return value of an `attributeBindings` monitored property is a boolean
- the property will follow HTML's pattern of repeating the attribute's name as
- its value:
+ if (dependentArray === previousDependentArray) {
+ // The array may be the same, but our item property keys may have
+ // changed, so we set them up again. We can't easily tell if they've
+ // changed: the array may be the same object, but with different
+ // contents.
+ if (cp._previousItemPropertyKeys[dependentKey]) {
+ delete cp._previousItemPropertyKeys[dependentKey];
+ meta.dependentArraysObserver.setupPropertyObservers(dependentKey, cp._itemPropertyKeys[dependentKey]);
+ }
+ } else {
+ meta.dependentArrays[dependentKey] = dependentArray;
- ```javascript
- MyTextInput = Ember.View.extend({
- tagName: 'input',
- attributeBindings: ['disabled'],
- disabled: true
- });
- ```
+ if (previousDependentArray) {
+ meta.dependentArraysObserver.teardownObservers(previousDependentArray, dependentKey);
+ }
- Will result in view instances with an HTML representation of:
+ if (dependentArray) {
+ meta.dependentArraysObserver.setupObservers(dependentArray, dependentKey);
+ }
+ }
+ }, this);
+ }, this);
- ```html
- <input id="ember1" class="ember-view" disabled="disabled" />
- ```
+ forEach(cp._dependentKeys, function(dependentKey) {
+ if (!partiallyRecomputeFor(this, dependentKey)) { return; }
- `attributeBindings` can refer to computed properties:
+ var dependentArray = get(this, dependentKey);
- ```javascript
- MyTextInput = Ember.View.extend({
- tagName: 'input',
- attributeBindings: ['disabled'],
- disabled: function() {
- if (someLogic) {
- return true;
- } else {
- return false;
+ if (dependentArray) {
+ addItems.call(this, dependentArray, callbacks, cp, propertyName, meta);
}
- }.property()
- });
- ```
-
- Updates to the the property of an attribute binding will result in automatic
- update of the HTML attribute in the view's rendered HTML representation.
+ }, this);
+ };
- `attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html)
- documentation for more information about concatenated properties.
- ## Templates
+ this.func = function (propertyName) {
+ Ember.assert('Computed reduce values require at least one dependent key', cp._dependentKeys);
- The HTML contents of a view's rendered representation are determined by its
- template. Templates can be any function that accepts an optional context
- parameter and returns a string of HTML that will be inserted within the
- view's tag. Most typically in Ember this function will be a compiled
- `Ember.Handlebars` template.
+ recompute.call(this, propertyName);
- ```javascript
- AView = Ember.View.extend({
- template: Ember.Handlebars.compile('I am the template')
- });
- ```
+ return cp._instanceMeta(this, propertyName).getValue();
+ };
+ }
- Will result in view instances with an HTML representation of:
+ ReduceComputedProperty.prototype = o_create(ComputedProperty.prototype);
- ```html
- <div id="ember1" class="ember-view">I am the template</div>
- ```
+ function defaultCallback(computedValue) {
+ return computedValue;
+ }
- Within an Ember application is more common to define a Handlebars templates as
- part of a page:
+ ReduceComputedProperty.prototype._callbacks = function () {
+ if (!this.callbacks) {
+ var options = this.options;
- ```html
- <script type='text/x-handlebars' data-template-name='some-template'>
- Hello
- </script>
- ```
+ this.callbacks = {
+ removedItem: options.removedItem || defaultCallback,
+ addedItem: options.addedItem || defaultCallback,
+ flushedChanges: options.flushedChanges || defaultCallback
+ };
+ }
- And associate it by name using a view's `templateName` property:
+ return this.callbacks;
+ };
- ```javascript
- AView = Ember.View.extend({
- templateName: 'some-template'
- });
- ```
+ ReduceComputedProperty.prototype._hasInstanceMeta = function (context, propertyName) {
+ return !!metaFor(context).cacheMeta[propertyName];
+ };
- If you have nested resources, your Handlebars template will look like this:
+ ReduceComputedProperty.prototype._instanceMeta = function (context, propertyName) {
+ var cacheMeta = metaFor(context).cacheMeta;
+ var meta = cacheMeta[propertyName];
- ```html
- <script type='text/x-handlebars' data-template-name='posts/new'>
- <h1>New Post</h1>
- </script>
- ```
+ if (!meta) {
+ meta = cacheMeta[propertyName] = new ReduceComputedPropertyInstanceMeta(context, propertyName, this.initialValue());
+ meta.dependentArraysObserver = new DependentArraysObserver(this._callbacks(), this, meta, context, propertyName, meta.sugarMeta);
+ }
- And `templateName` property:
+ return meta;
+ };
- ```javascript
- AView = Ember.View.extend({
- templateName: 'posts/new'
- });
- ```
+ ReduceComputedProperty.prototype.initialValue = function () {
+ if (typeof this.options.initialValue === 'function') {
+ return this.options.initialValue();
+ }
+ else {
+ return this.options.initialValue;
+ }
+ };
- Using a value for `templateName` that does not have a Handlebars template
- with a matching `data-template-name` attribute will throw an error.
+ ReduceComputedProperty.prototype.resetValue = function (value) {
+ return this.initialValue();
+ };
- For views classes that may have a template later defined (e.g. as the block
- portion of a `{{view}}` Handlebars helper call in another template or in
- a subclass), you can provide a `defaultTemplate` property set to compiled
- template function. If a template is not later provided for the view instance
- the `defaultTemplate` value will be used:
+ ReduceComputedProperty.prototype.itemPropertyKey = function (dependentArrayKey, itemPropertyKey) {
+ this._itemPropertyKeys[dependentArrayKey] = this._itemPropertyKeys[dependentArrayKey] || [];
+ this._itemPropertyKeys[dependentArrayKey].push(itemPropertyKey);
+ };
- ```javascript
- AView = Ember.View.extend({
- defaultTemplate: Ember.Handlebars.compile('I was the default'),
- template: null,
- templateName: null
- });
- ```
+ ReduceComputedProperty.prototype.clearItemPropertyKeys = function (dependentArrayKey) {
+ if (this._itemPropertyKeys[dependentArrayKey]) {
+ this._previousItemPropertyKeys[dependentArrayKey] = this._itemPropertyKeys[dependentArrayKey];
+ this._itemPropertyKeys[dependentArrayKey] = [];
+ }
+ };
- Will result in instances with an HTML representation of:
+ ReduceComputedProperty.prototype.property = function () {
+ var cp = this;
+ var args = a_slice.call(arguments);
+ var propertyArgs = {};
+ var match, dependentArrayKey, itemPropertyKey;
- ```html
- <div id="ember1" class="ember-view">I was the default</div>
- ```
+ forEach(args, function (dependentKey) {
+ if (doubleEachPropertyPattern.test(dependentKey)) {
+ throw new EmberError('Nested @each properties not supported: ' + dependentKey);
+ } else if (match = eachPropertyPattern.exec(dependentKey)) {
+ dependentArrayKey = match[1];
- If a `template` or `templateName` is provided it will take precedence over
- `defaultTemplate`:
+ var itemPropertyKeyPattern = match[2];
+ var addItemPropertyKey = function (itemPropertyKey) {
+ cp.itemPropertyKey(dependentArrayKey, itemPropertyKey);
+ };
- ```javascript
- AView = Ember.View.extend({
- defaultTemplate: Ember.Handlebars.compile('I was the default')
+ expandProperties(itemPropertyKeyPattern, addItemPropertyKey);
+ propertyArgs[guidFor(dependentArrayKey)] = dependentArrayKey;
+ } else {
+ propertyArgs[guidFor(dependentKey)] = dependentKey;
+ }
});
- aView = AView.create({
- template: Ember.Handlebars.compile('I was the template, not default')
- });
- ```
+ var propertyArgsToArray = [];
+ for (var guid in propertyArgs) {
+ propertyArgsToArray.push(propertyArgs[guid]);
+ }
- Will result in the following HTML representation when rendered:
+ return ComputedProperty.prototype.property.apply(this, propertyArgsToArray);
+ };
- ```html
- <div id="ember1" class="ember-view">I was the template, not default</div>
- ```
+ /**
+ Creates a computed property which operates on dependent arrays and
+ is updated with "one at a time" semantics. When items are added or
+ removed from the dependent array(s) a reduce computed only operates
+ on the change instead of re-evaluating the entire array.
- ## View Context
+ If there are more than one arguments the first arguments are
+ considered to be dependent property keys. The last argument is
+ required to be an options object. The options object can have the
+ following four properties:
- The default context of the compiled template is the view's controller:
+ `initialValue` - A value or function that will be used as the initial
+ value for the computed. If this property is a function the result of calling
+ the function will be used as the initial value. This property is required.
- ```javascript
- AView = Ember.View.extend({
- template: Ember.Handlebars.compile('Hello {{excitedGreeting}}')
- });
+ `initialize` - An optional initialize function. Typically this will be used
+ to set up state on the instanceMeta object.
- aController = Ember.Object.create({
- firstName: 'Barry',
- excitedGreeting: function() {
- return this.get("content.firstName") + "!!!"
- }.property()
- });
+ `removedItem` - A function that is called each time an element is removed
+ from the array.
- aView = AView.create({
- controller: aController,
- });
- ```
+ `addedItem` - A function that is called each time an element is added to
+ the array.
- Will result in an HTML representation of:
- ```html
- <div id="ember1" class="ember-view">Hello Barry!!!</div>
+ The `initialize` function has the following signature:
+
+ ```javascript
+ function(initialValue, changeMeta, instanceMeta)
```
- A context can also be explicitly supplied through the view's `context`
- property. If the view has neither `context` nor `controller` properties, the
- `parentView`'s context will be used.
+ `initialValue` - The value of the `initialValue` property from the
+ options object.
- ## Layouts
+ `changeMeta` - An object which contains meta information about the
+ computed. It contains the following properties:
- Views can have a secondary template that wraps their main template. Like
- primary templates, layouts can be any function that accepts an optional
- context parameter and returns a string of HTML that will be inserted inside
- view's tag. Views whose HTML element is self closing (e.g. `<input />`)
- cannot have a layout and this property will be ignored.
+ - `property` the computed property
+ - `propertyName` the name of the property on the object
- Most typically in Ember a layout will be a compiled `Ember.Handlebars`
- template.
+ `instanceMeta` - An object that can be used to store meta
+ information needed for calculating your computed. For example a
+ unique computed might use this to store the number of times a given
+ element is found in the dependent array.
- A view's layout can be set directly with the `layout` property or reference
- an existing Handlebars template by name with the `layoutName` property.
- A template used as a layout must contain a single use of the Handlebars
- `{{yield}}` helper. The HTML contents of a view's rendered `template` will be
- inserted at this location:
+ The `removedItem` and `addedItem` functions both have the following signature:
```javascript
- AViewWithLayout = Ember.View.extend({
- layout: Ember.Handlebars.compile("<div class='my-decorative-class'>{{yield}}</div>")
- template: Ember.Handlebars.compile("I got wrapped"),
- });
+ function(accumulatedValue, item, changeMeta, instanceMeta)
```
- Will result in view instances with an HTML representation of:
+ `accumulatedValue` - The value returned from the last time
+ `removedItem` or `addedItem` was called or `initialValue`.
- ```html
- <div id="ember1" class="ember-view">
- <div class="my-decorative-class">
- I got wrapped
- </div>
- </div>
- ```
+ `item` - the element added or removed from the array
- See [Ember.Handlebars.helpers.yield](/api/classes/Ember.Handlebars.helpers.html#method_yield)
- for more information.
+ `changeMeta` - An object which contains meta information about the
+ change. It contains the following properties:
- ## Responding to Browser Events
+ - `property` the computed property
+ - `propertyName` the name of the property on the object
+ - `index` the index of the added or removed item
+ - `item` the added or removed item: this is exactly the same as
+ the second arg
+ - `arrayChanged` the array that triggered the change. Can be
+ useful when depending on multiple arrays.
- Views can respond to user-initiated events in one of three ways: method
- implementation, through an event manager, and through `{{action}}` helper use
- in their template or layout.
+ For property changes triggered on an item property change (when
+ depKey is something like `someArray.@each.someProperty`),
+ `changeMeta` will also contain the following property:
- ### Method Implementation
+ - `previousValues` an object whose keys are the properties that changed on
+ the item, and whose values are the item's previous values.
- Views can respond to user-initiated events by implementing a method that
- matches the event name. A `jQuery.Event` object will be passed as the
- argument to this method.
+ `previousValues` is important Ember coalesces item property changes via
+ Ember.run.once. This means that by the time removedItem gets called, item has
+ the new values, but you may need the previous value (eg for sorting &
+ filtering).
- ```javascript
- AView = Ember.View.extend({
- click: function(event) {
- // will be called when when an instance's
- // rendered element is clicked
- }
- });
- ```
+ `instanceMeta` - An object that can be used to store meta
+ information needed for calculating your computed. For example a
+ unique computed might use this to store the number of times a given
+ element is found in the dependent array.
- ### Event Managers
+ The `removedItem` and `addedItem` functions should return the accumulated
+ value. It is acceptable to not return anything (ie return undefined)
+ to invalidate the computation. This is generally not a good idea for
+ arrayComputed but it's used in eg max and min.
- Views can define an object as their `eventManager` property. This object can
- then implement methods that match the desired event names. Matching events
- that occur on the view's rendered HTML or the rendered HTML of any of its DOM
- descendants will trigger this method. A `jQuery.Event` object will be passed
- as the first argument to the method and an `Ember.View` object as the
- second. The `Ember.View` will be the view whose rendered HTML was interacted
- with. This may be the view with the `eventManager` property or one of its
- descendent views.
+ Note that observers will be fired if either of these functions return a value
+ that differs from the accumulated value. When returning an object that
+ mutates in response to array changes, for example an array that maps
+ everything from some other array (see `Ember.computed.map`), it is usually
+ important that the *same* array be returned to avoid accidentally triggering observers.
+
+ Example
```javascript
- AView = Ember.View.extend({
- eventManager: Ember.Object.create({
- doubleClick: function(event, view) {
- // will be called when when an instance's
- // rendered element or any rendering
- // of this views's descendent
- // elements is clicked
- }
- })
- });
- ```
+ Ember.computed.max = function(dependentKey) {
+ return Ember.reduceComputed(dependentKey, {
+ initialValue: -Infinity,
- An event defined for an event manager takes precedence over events of the
- same name handled through methods on the view.
+ addedItem: function(accumulatedValue, item, changeMeta, instanceMeta) {
+ return Math.max(accumulatedValue, item);
+ },
- ```javascript
- AView = Ember.View.extend({
- mouseEnter: function(event) {
- // will never trigger.
- },
- eventManager: Ember.Object.create({
- mouseEnter: function(event, view) {
- // takes precedence over AView#mouseEnter
+ removedItem: function(accumulatedValue, item, changeMeta, instanceMeta) {
+ if (item < accumulatedValue) {
+ return accumulatedValue;
+ }
}
- })
- });
+ });
+ };
```
- Similarly a view's event manager will take precedence for events of any views
- rendered as a descendent. A method name that matches an event name will not
- be called if the view instance was rendered inside the HTML representation of
- a view that has an `eventManager` property defined that handles events of the
- name. Events not handled by the event manager will still trigger method calls
- on the descendent.
+ Dependent keys may refer to `@this` to observe changes to the object itself,
+ which must be array-like, rather than a property of the object. This is
+ mostly useful for array proxies, to ensure objects are retrieved via
+ `objectAtContent`. This is how you could sort items by properties defined on an item controller.
+
+ Example
```javascript
- OuterView = Ember.View.extend({
- template: Ember.Handlebars.compile("outer {{#view InnerView}}inner{{/view}} outer"),
- eventManager: Ember.Object.create({
- mouseEnter: function(event, view) {
- // view might be instance of either
- // OuterView or InnerView depending on
- // where on the page the user interaction occured
- }
+ App.PeopleController = Ember.ArrayController.extend({
+ itemController: 'person',
+
+ sortedPeople: Ember.computed.sort('@this.@each.reversedName', function(personA, personB) {
+ // `reversedName` isn't defined on Person, but we have access to it via
+ // the item controller App.PersonController. If we'd used
+ // `content.@each.reversedName` above, we would be getting the objects
+ // directly and not have access to `reversedName`.
+ //
+ var reversedNameA = get(personA, 'reversedName');
+ var reversedNameB = get(personB, 'reversedName');
+
+ return Ember.compare(reversedNameA, reversedNameB);
})
});
- InnerView = Ember.View.extend({
- click: function(event) {
- // will be called if rendered inside
- // an OuterView because OuterView's
- // eventManager doesn't handle click events
- },
- mouseEnter: function(event) {
- // will never be called if rendered inside
- // an OuterView.
- }
+ App.PersonController = Ember.ObjectController.extend({
+ reversedName: function() {
+ return reverse(get(this, 'name'));
+ }.property('name')
});
```
- ### Handlebars `{{action}}` Helper
-
- See [Handlebars.helpers.action](/api/classes/Ember.Handlebars.helpers.html#method_action).
-
- ### Event Names
-
- All of the event handling approaches described above respond to the same set
- of events. The names of the built-in events are listed below. (The hash of
- built-in events exists in `Ember.EventDispatcher`.) Additional, custom events
- can be registered by using `Ember.Application.customEvents`.
-
- Touch events:
-
- * `touchStart`
- * `touchMove`
- * `touchEnd`
- * `touchCancel`
-
- Keyboard events
-
- * `keyDown`
- * `keyUp`
- * `keyPress`
-
- Mouse events
-
- * `mouseDown`
- * `mouseUp`
- * `contextMenu`
- * `click`
- * `doubleClick`
- * `mouseMove`
- * `focusIn`
- * `focusOut`
- * `mouseEnter`
- * `mouseLeave`
+ Dependent keys whose values are not arrays are treated as regular
+ dependencies: when they change, the computed property is completely
+ recalculated. It is sometimes useful to have dependent arrays with similar
+ semantics. Dependent keys which end in `.[]` do not use "one at a time"
+ semantics. When an item is added or removed from such a dependency, the
+ computed property is completely recomputed.
- Form events:
+ When the computed property is completely recomputed, the `accumulatedValue`
+ is discarded, it starts with `initialValue` again, and each item is passed
+ to `addedItem` in turn.
- * `submit`
- * `change`
- * `focusIn`
- * `focusOut`
- * `input`
+ Example
- HTML5 drag and drop events:
+ ```javascript
+ Ember.Object.extend({
+ // When `string` is changed, `computed` is completely recomputed.
+ string: 'a string',
- * `dragStart`
- * `drag`
- * `dragEnter`
- * `dragLeave`
- * `dragOver`
- * `dragEnd`
- * `drop`
+ // When an item is added to `array`, `addedItem` is called.
+ array: [],
- ## Handlebars `{{view}}` Helper
+ // When an item is added to `anotherArray`, `computed` is completely
+ // recomputed.
+ anotherArray: [],
- Other `Ember.View` instances can be included as part of a view's template by
- using the `{{view}}` Handlebars helper. See [Ember.Handlebars.helpers.view](/api/classes/Ember.Handlebars.helpers.html#method_view)
- for additional information.

- /**
+ Ember versions prior to 1.7 used `model` as an alias of `content`, but due to

- with a `type` value of either `text` or `checkbox`. If no `type` is provided,
- `text` will be the default value applied. The attributes of `{{input}}`
- match those of the native HTML tag as closely as possible for these two types.
+ This change reduces many caveats with model/content, and also sets a
+ simple ground rule: Never set a controllers content, rather always set
+ it's model and ember will do the right thing.
- ## Use as text field
- An `{{input}}` with no `type` or a `type` of `text` will render an HTML text input.
- The following HTML attributes can be set via the helper:

/**
- `{{textarea}}` inserts a new instance of `<textarea>` tag into the template.
- The attributes of `{{textarea}}` match those of the native HTML tags as
- closely as possible.
+ This mixin defines the common interface implemented by enumerable objects
+ in Ember. Most of these methods follow the standard Array iteration
+ API defined up to JavaScript 1.8 (excluding language-specific features that
+ cannot be emulated in older versions of JavaScript).
- The following HTML attributes can be set:
+ This mixin is applied automatically to the Array class on page load, so you
+ can use any of these methods on simple arrays. If Array already implements
+ one of these methods, the mixin will not override them.
- * `value`
- * `name`
- * `rows`
- * `cols`
- * `placeholder`
- * `disabled`
- * `maxlength`
- * `tabindex`
- * `selectionEnd`
- * `selectionStart`
- * `selectionDirection`
- * `wrap`
- * `readonly`
- * `autofocus`
- * `form`
- * `spellcheck`
- * `required`
+ ## Writing Your Own Enumerable
- When set to a quoted string, these value will be directly applied to the HTML
- element. When left unquoted, these values will be bound to a property on the
- template's current rendering context (most typically a controller instance).
+ To make your own custom class enumerable, you need two items:
- Unbound:
+ 1. You must have a length property. This property should change whenever
+ the number of items in your enumerable object changes. If you use this
+ with an `Ember.Object` subclass, you should be sure to change the length
+ property using `set().`
- ```handlebars
- {{textarea value="Lots of static text that ISN'T bound"}}
- ```
+ 2. You must implement `nextObject().` See documentation.
- Would result in the following HTML:
+ Once you have these two methods implemented, apply the `Ember.Enumerable` mixin
+ to your class and you will be able to enumerate the contents of your object
+ like any other collection.
- ```html
- <textarea class="ember-text-area">
- Lots of static text that ISN'T bound
- </textarea>
- ```
+ ## Using Ember Enumeration with Other Libraries
- Bound:
+ Many other libraries provide some kind of iterator or enumeration like
+ facility. This is often where the most common API conflicts occur.
+ Ember's API is designed to be as friendly as possible with other
+ libraries by implementing only methods that mostly correspond to the
+ JavaScript 1.8 API.
- In the following example, the `writtenWords` property on `App.ApplicationController`
- will be updated live as the user types 'Lots of text that IS bound' into
- the text area of their browser's window.
+ @class Enumerable
+ @namespace Ember
+ @since Ember 0.9
+ */
+ __exports__["default"] = Mixin.create({
- ```javascript
- App.ApplicationController = Ember.Controller.extend({
- writtenWords: "Lots of text that IS bound"
- });
- ```
+ /**
+ Implement this method to make your class enumerable.
- ```handlebars
- {{textarea value=writtenWords}}
- ```
+ This method will be call repeatedly during enumeration. The index value
+ will always begin with 0 and increment monotonically. You don't have to
+ rely on the index value to determine what object to return, but you should
+ always check the value and start from the beginning when you see the
+ requested index is 0.
- Would result in the following HTML:
+ The `previousObject` is the object that was returned from the last call
+ to `nextObject` for the current iteration. This is a useful way to
+ manage iteration if you are tracing a linked list, for example.
- ```html
- <textarea class="ember-text-area">
- Lots of text that IS bound
- </textarea>
- ```
+ Finally the context parameter will always contain a hash you can use as
+ a "scratchpad" to maintain any other state you need in order to iterate
+ properly. The context object is reused and is not reset between
+ iterations so make sure you setup the context with a fresh state whenever
+ the index parameter is 0.
- If you wanted a one way binding between the text area and a div tag
- somewhere else on your screen, you could use `Ember.computed.oneWay`:
+ Generally iterators will continue to call `nextObject` until the index
+ reaches the your current length-1. If you run out of data before this
+ time for some reason, you should simply return undefined.
- ```javascript
- App.ApplicationController = Ember.Controller.extend({
- writtenWords: "Lots of text that IS bound",
- outputWrittenWords: Ember.computed.oneWay("writtenWords")
- });
- ```
+ The default implementation of this method simply looks up the index.
+ This works great on any Array-like objects.
- ```handlebars
- {{textarea value=writtenWords}}
+ @method nextObject
+ @param {Number} index the current index of the iteration
+ @param {Object} previousObject the value returned by the last call to
+ `nextObject`.
+ @param {Object} context a context object you can use to maintain state.
+ @return {Object} the next object in the iteration or undefined
+ */
+ nextObject: required(Function),
- <div>
- {{outputWrittenWords}}
- </div>
- ```
+ /**
+ Helper method returns the first object from a collection. This is usually
+ used by bindings and other parts of the framework to extract a single
+ object if the enumerable contains only one item.
- Would result in the following HTML:
+ If you override this method, you should implement it so that it will
+ always return the same value each time it is called. If your enumerable
+ contains only one object, this method should always return that object.
+ If your enumerable is empty, this method should return `undefined`.
- ```html
- <textarea class="ember-text-area">
- Lots of text that IS bound
- </textarea>
+ ```javascript
+ var arr = ["a", "b", "c"];
+ arr.get('firstObject'); // "a"
- <-- the following div will be updated in real time as you type -->
+ var arr = [];
+ arr.get('firstObject'); // undefined
+ ```
- <div>
- Lots of text that IS bound
- </div>
- ```
+ @property firstObject
+ @return {Object} the object or undefined
+ */
+ firstObject: computed('[]', function() {
+ if (get(this, 'length')===0) return undefined ;
- Finally, this example really shows the power and ease of Ember when two
- properties are bound to eachother via `Ember.computed.alias`. Type into
- either text area box and they'll both stay in sync. Note that
- `Ember.computed.alias` costs more in terms of performance, so only use it when
- your really binding in both directions:
+ // handle generic enumerables
+ var context = popCtx(), ret;
+ ret = this.nextObject(0, null, context);
+ pushCtx(context);
+ return ret;
+ }),
- ```javascript
- App.ApplicationController = Ember.Controller.extend({
- writtenWords: "Lots of text that IS bound",
- twoWayWrittenWords: Ember.computed.alias("writtenWords")
- });
- ```
+ /**
+ Helper method returns the last object from a collection. If your enumerable
+ contains only one object, this method should always return that object.
+ If your enumerable is empty, this method should return `undefined`.
- ```handlebars
- {{textarea value=writtenWords}}
- {{textarea value=twoWayWrittenWords}}
- ```
+ ```javascript
+ var arr = ["a", "b", "c"];
+ arr.get('lastObject'); // "c"
- ```html
- <textarea id="ember1" class="ember-text-area">

+ var arr = [];
+ arr.get('lastObject'); // undefined
+ ```
- <-- both updated in real time -->

+ @return {Object} the last object or undefined
+ */

+ var len = get(this, 'length');
+ if (len===0) return undefined ;

- ```
+ ```javascript

+ },
- In this case, when the `name` property of the template's context changes,
- the rendered value of the helper will update to reflect this change.
+ // ..........................................................
+ // IMPLEMENT Ember.MutableEnumerable
+ //
- ## Example with options
+ /**
+ Remove all occurances of an object in the array.
- Like normal handlebars helpers, bound helpers have access to the options
- passed into the helper call.

- var count = options.hash.count;
- var a = [];
- while(a.length < count) {
- a.push(value);
- }
- return a.join('');
- });
- ```
+ @method removeObject
+ @param {*} obj object to remove
+ @return {Ember.Array} receiver

+ while(--loc >= 0) {
+ var curObject = this.objectAt(loc);
+ if (curObject === obj) this.removeAt(loc);
+ }
+ return this;
+ },
- This helper could be used in a template as follows:
+ /**
+ Push the object onto the end of the array if it is not already
+ present in the array.
- ```handlebars
- {{repeat text count=3}}
- ```
+ ```javascript
+ var cities = ["Chicago", "Berlin"];

- ```handlebars
- {{repeat text countBinding="numRepeats"}}
- ```
+ /**

- the `numRepeats` property on the context. If that property
- changes, the helper will be re-rendered.
+ /**
+ This mixin defines the API for modifying generic enumerables. These methods
+ can be applied to an object regardless of whether it is ordered or
+ unordered.
- ## Example with extra dependencies
+ Note that an Enumerable can change even if it does not implement this mixin.
+ For example, a MappedEnumerable cannot be directly modified but if its
+ underlying enumerable changes, it will change also.
- The `Ember.Handlebars.registerBoundHelper` method takes a variable length
- third parameter which indicates extra dependencies on the passed in value.
- This allows the handlebars helper to update when these dependencies change.
+ ## Adding Objects
+
+ To add an object to an enumerable, use the `addObject()` method. This
+ method will only add the object to the enumerable if the object is not
+ already present and is of a type supported by the enumerable.
```javascript
- Ember.Handlebars.registerBoundHelper('capitalizeName', function(value) {
- return value.get('name').toUpperCase();
- }, 'name');
+ set.addObject(contact);
```
- ## Example with multiple bound properties
+ ## Removing Objects
- `Ember.Handlebars.registerBoundHelper` supports binding to
- multiple properties, e.g.:
+ To remove an object from an enumerable, use the `removeObject()` method. This
+ will only remove the object if it is present in the enumerable, otherwise
+ this method has no effect.
```javascript
- Ember.Handlebars.registerBoundHelper('concatenate', function() {
- var values = Array.prototype.slice.call(arguments, 0, -1);
- return values.join('||');
- });
+ set.removeObject(contact);
```
- Which allows for template syntax such as `{{concatenate prop1 prop2}}` or
- `{{concatenate prop1 prop2 prop3}}`. If any of the properties change,
- the helpr will re-render. Note that dependency keys cannot be
- using in conjunction with multi-property helpers, since it is ambiguous
- which property the dependent keys would belong to.
-
- ## Use with unbound helper
-
- The `{{unbound}}` helper can be used with bound helper invocations
- to render them in their unbound form, e.g.
-
- ```handlebars
- {{unbound capitalize name}}
- ```
+ ## Implementing In Your Own Code
- In this example, if the name property changes, the helper
- will not re-render.
+ If you are implementing an object and want to support this API, just include
+ this mixin in your class and implement the required methods. In your unit
+ tests, be sure to apply the Ember.MutableEnumerableTests to your object.
- ## Use with blocks not supported

+ models, controllers and views communicate with each other in an Ember
+ application.
- // Run the supplied helper function.
- return fn.apply(currentContext, args);
- };
+ Any object that has this mixin applied can be used in observer
+ operations. That includes `Ember.Object` and most objects you will
+ interact with as you write your Ember application.
- view.appendChild(bindView);
+ Note that you will not generally apply this mixin to classes yourself,
+ but you will use the features provided by this module frequently, so it
+ is important to understand how to use it.
- // Assemble list of watched properties that'll re-render this helper.
- for (boundOption in boundOptions) {
- if (boundOptions.hasOwnProperty(boundOption)) {
- watchedProperties.push(normalizePath(currentContext, boundOptions[boundOption], data));

- // Observe each property.
- for (loc = 0, len = watchedProperties.length; loc < len; ++loc) {
- property = watchedProperties[loc];
- view.registerObserver(property.root, property.path, bindView, bindView.rerender);
- }
+ Because of Ember's support for bindings and observers, you will always
+ access properties using the get method, and set properties using the
+ set method. This allows the observing objects to be notified and
+ computed properties to be handled properly.
- if (types[0] !== 'ID' || normalizedProperties.length === 0) {
- return;
- }
+ More documentation about `get` and `set` are below.
- // Add dependent key observers to the first param
- var normalized = normalizedProperties[0],
- pathRoot = normalized.root,
- path = normalized.path;
+ ## Observing Property Changes
- if(!isEmpty(path)) {
- prefixPathForDependentKeys = path + '.';
- }
- for (var i=0, l=dependentKeys.length; i<l; i++) {
- view.registerObserver(pathRoot, prefixPathForDependentKeys + dependentKeys[i], bindView, bindView.rerender);
- }
- }
+ You typically observe property changes simply by adding the `observes`
+ call to the end of your method declarations in classes that you write.
+ For example:
- helper._rawFunction = fn;
- return helper;
- };
+ ```javascript
+ Ember.Object.extend({
+ valueObserver: function() {
+ // Executes whenever the "value" property changes
+ }.observes('value')
+ });
+ ```
- /**
- Renders the unbound form of an otherwise bound helper function.

+ is actually built into the `Ember.Object` class on top of two methods
+ defined in this mixin: `addObserver` and `removeObserver`. You can use
+ these two methods to add and remove observers yourself if you need to

+ Computed properties are methods defined with the `property` modifier

+ Likewise, if you try to call `get` on a property whose value is
+ `undefined`, the `unknownProperty()` method will be called on the object.
+ If this method returns any value other than `undefined`, it will be returned
+ instead. This allows you to implement "virtual" properties that are
+ not defined upfront.

+ ### Unknown Properties
- output = handlebarsGetEscaped(currentContext, property, options);
+ If you try to set a value on a key that is undefined in the target
+ object, then the `setUnknownProperty()` handler will be called instead. This
+ gives you an opportunity to implement complex "virtual" properties that
+ are not predefined on the object. If `setUnknownProperty()` returns

- data.buffer.push(output);

- );
+ ### Property Observers
- bindView._parentView = view;
- view.appendChild(bindView);
+ In addition to changing the property, `set()` will also register a property
+ change with the object. Unless you have placed this call inside of a
+ `beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers
+ (i.e. observer methods declared on the same object), will be called
+ immediately. Any "remote" observers (i.e. observer methods declared on
+ another object) will be placed in a queue and called at a later time in a
+ coalesced manner.
- observer = function() {

- output = handlebarsGetEscaped(currentContext, property, options);

- function shouldDisplayIfHelperContent(result) {
- var truthy = result && get(result, 'isTruthy');
- if (typeof truthy === 'boolean') { return truthy; }

- normalized, propertyValue, result;
+ ### Observer Methods
- normalized = normalizePath(context, property, data);
- propertyValue = handlebarsGet(context, property, fn);
+ Observer methods you pass should generally have the following signature if
+ you do not pass a `context` parameter:
- if (!shouldDisplayIfHelperContent(propertyValue)) {
- template = inverse;
- }
+ ```javascript
+ fooDidChange: function(sender, key, value, rev) { };
+ ```
- template(context, { data: data });
- }
+ The sender is the object that changed. The key is the property that
+ changes. The value property is currently reserved and unused. The rev
+ is the last property revision of the object when it changed, which you can
+ use to detect if the key value has really changed or not.
- /**
- Use the `{{with}}` helper when you want to scope context. Take the following code as an example:
+ If you pass a `context` parameter, the context will be passed before the
+ revision like so:
- ```handlebars
- <h5>{{user.name}}</h5>
+ ```javascript
+ fooDidChange: function(sender, key, value, context, rev) { };
+ ```
- <div class="role">
- <h6>{{user.role.label}}</h6>
- <span class="role-id">{{user.role.id}}</span>
+ Usually you will not need the value, context or revision parameters at
+ the end. In this case, it is common to write observer methods that take
+ only a sender and key value as parameters or, if you aren't interested in
+ any of these values, to write an observer that has no parameters at all.
- <p class="role-desc">{{user.role.description}}</p>
- </div>
- ```
+ @method addObserver
+ @param {String} key The key to observer
+ @param {Object} target The target object to invoke
+ @param {String|Function} method The method to invoke.
+ */
+ addObserver: function(key, target, method) {
+ addObserver(this, key, target, method);
+ },
- `{{with}}` can be our best friend in these cases,
- instead of writing `user.role.*` over and over, we use `{{#with user.role}}`.
- Now the context within the `{{#with}} .. {{/with}}` block is `user.role` so you can do the following:
+ /**
+ Remove an observer you have previously registered on this object. Pass
+ the same key, target, and method you passed to `addObserver()` and your
+ target will no longer receive notifications.
- ```handlebars
- <h5>{{user.name}}</h5>
+ @method removeObserver
+ @param {String} key The key to observer
+ @param {Object} target The target object to invoke
+ @param {String|Function} method The method to invoke.

- ### `as` operator
+ /**
+ Retrieves the value of a property, or a default value in the case that the

- default scope or to reference from another `{{with}}` block.

- the first part of the property path, `foo`. Instead, use `{{#with foo.bar as baz}}`.

- `bind-attr` allows you to create a binding between DOM element attributes and

- <img {{bind-attr src="imageUrl" alt="imageTitle"}}>
+ ```javascript
+ controller.get('isPending') //=> false
+ controller.get('isSettled') //=> true
+ controller.get('isRejected') //=> false
+ controller.get('isFulfilled') //=> true
```
- The above handlebars template will fill the `<img>`'s `src` attribute will
- the value of the property referenced with `"imageUrl"` and its `alt`
- attribute with the value of the property referenced with `"imageTitle"`.
-
- If the rendering context of this template is the following object:
+ As the controller is an ObjectController, and the json now its content,
+ all the json properties will be available directly from the controller.
```javascript
+ // Assuming the following json:
{
- imageUrl: 'http://lolcats.info/haz-a-funny',
- imageTitle: 'A humorous image of a cat'
+ firstName: 'Stefan',
+ lastName: 'Penner'
}
- ```
-
- The resulting HTML output will be:
- ```html
- <img src="http://lolcats.info/haz-a-funny" alt="A humorous image of a cat">
+ // both properties will accessible on the controller
+ controller.get('firstName') //=> 'Stefan'
+ controller.get('lastName') //=> 'Penner'
```
- `bind-attr` cannot redeclare existing DOM element attributes. The use of `src`
- in the following `bind-attr` example will be ignored and the hard coded value
- of `src="/failwhale.gif"` will take precedence:
+ If the controller is backing a template, the attributes are
+ bindable from within that template
```handlebars
- <img src="/failwhale.gif" {{bind-attr src="imageUrl" alt="imageTitle"}}>
+ {{#if isPending}}
+ loading...

+ `Ember.SortableMixin` provides a standard interface for array proxies
+ to specify a sort order and maintain this sorting when objects are added,
+ removed, or updated without changing the implicit order of their underlying
+ modelarray:
+
+ ```javascript
+ songs = [
+ {trackNumber: 4, title: 'Ob-La-Di, Ob-La-Da'},
+ {trackNumber: 2, title: 'Back in the U.S.S.R.'},
+ {trackNumber: 3, title: 'Glass Onion'},

+
+ songsController.addObject({trackNumber: 1, title: 'Dear Prudence'});
+ songsController.get('firstObject'); // {trackNumber: 1, title: 'Dear Prudence'}
```
- Results in the following rendered output:
+ If you add or remove the properties to sort by or change the sort direction the model
+ sort order will be automatically updated.
- ```html
- <img class="class-name-to-always-apply">
+ ```javascript

- hard-coded value – can be combined in a single declaration:

/**
- `{{collection}}` is a `Ember.Handlebars` helper for adding instances of
- `Ember.CollectionView` to a template. See [Ember.CollectionView](/api/classes/Ember.CollectionView.html)
- for additional information on how a `CollectionView` functions.
-
- `{{collection}}`'s primary use is as a block helper with a `contentBinding`
- option pointing towards an `Ember.Array`-compatible object. An `Ember.View`
- instance will be created for each item in its `content` property. Each view
- will have its own `content` property set to the appropriate item in the
- collection.
-
- The provided block will be applied as the template for each item's view.
-
- Given an empty `<body>` the following template:
-
- ```handlebars
- {{#collection contentBinding="App.items"}}
- Hi {{view.content.name}}
- {{/collection}}
- ```
+ `Ember.TargetActionSupport` is a mixin that can be included in a class
+ to add a `triggerAction` method with semantics similar to the Handlebars
+ `{{action}}` helper. In normal Ember usage, the `{{action}}` helper is
+ usually the best choice. This mixin is most often useful when you are
+ doing more complex event handling in View objects.
- And the following application code
+ See also `Ember.ViewTargetActionSupport`, which has
+ view-aware defaults for target and actionContext.
- ```javascript
- App = Ember.Application.create()
- App.items = [
- Ember.Object.create({name: 'Dave'}),
- Ember.Object.create({name: 'Mary'}),
- Ember.Object.create({name: 'Sara'})
- ]
- ```
+ @class TargetActionSupport
+ @namespace Ember
+ @extends Ember.Mixin
+ */
+ var TargetActionSupport = Mixin.create({
+ target: null,
+ action: null,
+ actionContext: null,
- Will result in the HTML structure below
+ targetObject: computed(function() {
+ var target = get(this, 'target');
- ```html
- <div class="ember-view">
- <div class="ember-view">Hi Dave</div>
- <div class="ember-view">Hi Mary</div>
- <div class="ember-view">Hi Sara</div>
- </div>
- ```
+ if (typeOf(target) === "string") {
+ var value = get(this, target);
+ if (value === undefined) { value = get(Ember.lookup, target); }
+ return value;
+ } else {
+ return target;
+ }
+ }).property('target'),
- ### Blockless use in a collection
+ actionContextObject: computed(function() {
+ var actionContext = get(this, 'actionContext');
- If you provide an `itemViewClass` option that has its own `template` you can
- omit the block.
+ if (typeOf(actionContext) === "string") {
+ var value = get(this, actionContext);
+ if (value === undefined) { value = get(Ember.lookup, actionContext); }
+ return value;
+ } else {
+ return actionContext;
+ }
+ }).property('actionContext'),
- The following template:
+ /**
+ Send an `action` with an `actionContext` to a `target`. The action, actionContext
+ and target will be retrieved from properties of the object. For example:
- ```handlebars
- {{collection contentBinding="App.items" itemViewClass="App.AnItemView"}}
+ ```javascript
+ App.SaveButtonView = Ember.View.extend(Ember.TargetActionSupport, {
+ target: Ember.computed.alias('controller'),
+ action: 'save',
+ actionContext: Ember.computed.alias('context'),
+ click: function() {
+ this.triggerAction(); // Sends the `save` action, along with the current context
+ // to the current controller
+ }
+ });
```
- And application code
+ The `target`, `action`, and `actionContext` can be provided as properties of
+ an optional object argument to `triggerAction` as well.
```javascript
- App = Ember.Application.create();
- App.items = [
- Ember.Object.create({name: 'Dave'}),
- Ember.Object.create({name: 'Mary'}),
- Ember.Object.create({name: 'Sara'})
- ];
-
- App.AnItemView = Ember.View.extend({
- template: Ember.Handlebars.compile("Greetings {{view.content.name}}")
+ App.SaveButtonView = Ember.View.extend(Ember.TargetActionSupport, {
+ click: function() {
+ this.triggerAction({
+ action: 'save',
+ target: this.get('controller'),
+ actionContext: this.get('context')
+ }); // Sends the `save` action, along with the current context
+ // to the current controller
+ }
});
```
- Will result in the HTML structure below
+ The `actionContext` defaults to the object you are mixing `TargetActionSupport` into.
+ But `target` and `action` must be specified either as properties or with the argument
+ to `triggerAction`, or a combination:
- ```html
- <div class="ember-view">
- <div class="ember-view">Greetings Dave</div>
- <div class="ember-view">Greetings Mary</div>
- <div class="ember-view">Greetings Sara</div>
- </div>
+ ```javascript
+ App.SaveButtonView = Ember.View.extend(Ember.TargetActionSupport, {
+ target: Ember.computed.alias('controller'),
+ click: function() {
+ this.triggerAction({
+ action: 'save'
+ }); // Sends the `save` action, along with a reference to `this`,
+ // to the current controller
+ }
+ });
```
- ### Specifying a CollectionView subclass
-
- By default the `{{collection}}` helper will create an instance of
- `Ember.CollectionView`. You can supply a `Ember.CollectionView` subclass to
- the helper by passing it as the first argument:
-
- ```handlebars
- {{#collection App.MyCustomCollectionClass contentBinding="App.items"}}
- Hi {{view.content.name}}
- {{/collection}}
- ```
+ @method triggerAction
+ @param opts {Hash} (optional, with the optional keys action, target and/or actionContext)
+ @return {Boolean} true if the action was sent successfully and did not return false
+ */
+ triggerAction: function(opts) {
+ opts = opts || {};
+ var action = opts.action || get(this, 'action');
+ var target = opts.target || get(this, 'targetObject');
+ var actionContext = opts.actionContext;
- ### Forwarded `item.*`-named Options
+ function args(options, actionName) {
+ var ret = [];
+ if (actionName) { ret.push(actionName); }
- As with the `{{view}}`, helper options passed to the `{{collection}}` will be
- set on the resulting `Ember.CollectionView` as properties. Additionally,
- options prefixed with `item` will be applied to the views rendered for each
- item (note the camelcasing):
+ return ret.concat(options);
+ }
- ```handlebars
- {{#collection contentBinding="App.items"
- itemTagName="p"
- itemClassNames="greeting"}}
- Howdy {{view.content.name}}
- {{/collection}}
- ```
+ if (typeof actionContext === 'undefined') {
+ actionContext = get(this, 'actionContextObject') || this;
+ }
- Will result in the following HTML structure:
+ if (target && action) {
+ var ret;
- ```html
- <div class="ember-view">
- <p class="ember-view greeting">Howdy Dave</p>
- <p class="ember-view greeting">Howdy Mary</p>
- <p class="ember-view greeting">Howdy Sara</p>
- </div>
- ```
+ if (target.send) {
+ ret = target.send.apply(target, args(actionContext, action));
+ } else {
+ Ember.assert("The action '" + action + "' did not exist on " + target, typeof target[action] === 'function');
+ ret = target[action].apply(target, args(actionContext));
+ }

- ```
- ### Specifying a View class for items
- If you provide an `itemViewClass` option that references a view class
- with its own `template` you can omit the block.
+ var undefinedDescriptor = {
+ configurable: true,
+ writable: true,
+ enumerable: false,
+ value: undefined
+ };
- The following template:
+ var nullDescriptor = {
+ configurable: true,
+ writable: true,
+ enumerable: false,
+ value: null
+ };
- ```handlebars
- {{#view App.MyView }}
- {{each view.items itemViewClass="App.AnItemView"}}
- {{/view}}
- ```
+ function makeCtor() {
- And application code
+ // Note: avoid accessing any properties on the object since it makes the
+ // method a lot faster. This is glue code so we want it to be as fast as
+ // possible.
- ```javascript
- App = Ember.Application.create({
- MyView: Ember.View.extend({
- items: [
- Ember.Object.create({name: 'Dave'}),
- Ember.Object.create({name: 'Mary'}),
- Ember.Object.create({name: 'Sara'})
- ]
- })
- });
+ var wasApplied = false;
+ var initMixins, initProperties;
- App.AnItemView = Ember.View.extend({
- template: Ember.Handlebars.compile("Greetings {{name}}")
- });
- ```
+ var Class = function() {
+ if (!wasApplied) {
+ Class.proto(); // prepare prototype...
+ }
+ o_defineProperty(this, GUID_KEY, nullDescriptor);
+ o_defineProperty(this, '__nextSuper', undefinedDescriptor);
+ var m = meta(this);
+ var proto = m.proto;
+ m.proto = this;
+ if (initMixins) {
+ // capture locally so we can clear the closed over variable
+ var mixins = initMixins;
+ initMixins = null;
+ apply(this, this.reopen, mixins);
+ }
+ if (initProperties) {
+ // capture locally so we can clear the closed over variable
+ var props = initProperties;
+ initProperties = null;
- Will result in the HTML structure below
+ var concatenatedProperties = this.concatenatedProperties;
- ```html
- <div class="ember-view">
- <div class="ember-view">Greetings Dave</div>
- <div class="ember-view">Greetings Mary</div>
- <div class="ember-view">Greetings Sara</div>
- </div>
- ```
+ for (var i = 0, l = props.length; i < l; i++) {
+ var properties = props[i];
- If an `itemViewClass` is defined on the helper, and therefore the helper is not
- being used as a block, an `emptyViewClass` can also be provided optionally.
- The `emptyViewClass` will match the behavior of the `{{else}}` condition
- described above. That is, the `emptyViewClass` will render if the collection
- is empty.
+ Ember.assert("Ember.Object.create no longer supports mixing in other definitions, use createWithMixins instead.", !(properties instanceof Mixin));
- ### Representing each item with a Controller.
- By default the controller lookup within an `{{#each}}` block will be
- the controller of the template where the `{{#each}}` was used. If each
- item needs to be presented by a custom controller you can provide a
- `itemController` option which references a controller by lookup name.
- Each item in the loop will be wrapped in an instance of this controller
- and the item itself will be set to the `content` property of that controller.
+ if (typeof properties !== 'object' && properties !== undefined) {
+ throw new EmberError("Ember.Object.create only accepts objects.");
+ }
- This is useful in cases where properties of model objects need transformation
- or synthesis for display:
+ if (!properties) { continue; }
- ```javascript
- App.DeveloperController = Ember.ObjectController.extend({
- isAvailableForHire: function() {
- return !this.get('content.isEmployed') && this.get('content.isSeekingWork');
- }.property('isEmployed', 'isSeekingWork')
- })
- ```
+ var keyNames = keys(properties);
- ```handlebars
- {{#each person in developers itemController="developer"}}
- {{person.name}} {{#if person.isAvailableForHire}}Hire me!{{/if}}
- {{/each}}
- ```
+ for (var j = 0, ll = keyNames.length; j < ll; j++) {
+ var keyName = keyNames[j];
+ if (!properties.hasOwnProperty(keyName)) { continue; }
- Each itemController will receive a reference to the current controller as
- a `parentController` property.
+ var value = properties[keyName];
- ### (Experimental) Grouped Each
+ if (IS_BINDING.test(keyName)) {
+ var bindings = m.bindings;
+ if (!bindings) {
+ bindings = m.bindings = {};
+ } else if (!m.hasOwnProperty('bindings')) {
+ bindings = m.bindings = o_create(m.bindings);
+ }
+ bindings[keyName] = value;
+ }
- When used in conjunction with the experimental [group helper](https://github.com/emberjs/group-helper),
- you can inform Handlebars to re-render an entire group of items instead of
- re-rendering them one at a time (in the event that they are changed en masse
- or an item is added/removed).
+ var desc = m.descs[keyName];
- ```handlebars
- {{#group}}
- {{#each people}}
- {{firstName}} {{lastName}}
- {{/each}}
- {{/group}}
- ```
+ Ember.assert("Ember.Object.create no longer supports defining computed properties. Define computed properties using extend() or reopen() before calling create().", !(value instanceof ComputedProperty));
+ Ember.assert("Ember.Object.create no longer supports defining methods that call _super.", !(typeof value === 'function' && value.toString().indexOf('._super') !== -1));
+ Ember.assert("`actions` must be provided at extend time, not at create " +
+ "time, when Ember.ActionHandler is used (i.e. views, " +
+ "controllers & routes).", !((keyName === 'actions') && ActionHandler.detect(this)));
- This can be faster than the normal way that Handlebars re-renders items
- in some cases.
+ if (concatenatedProperties && indexOf(concatenatedProperties, keyName) >= 0) {
+ var baseValue = this[keyName];
- If for some reason you have a group with more than one `#each`, you can make
- one of the collections be updated in normal (non-grouped) fashion by setting
- the option `groupedRows=true` (counter-intuitive, I know).
+ if (baseValue) {
+ if ('function' === typeof baseValue.concat) {
+ value = baseValue.concat(value);
+ } else {
+ value = makeArray(baseValue).concat(value);
+ }
+ } else {
+ value = makeArray(value);
+ }
+ }
- For example,
+ if (desc) {
+ desc.set(this, keyName, value);
+ } else {
+ if (typeof this.setUnknownProperty === 'function' && !(keyName in this)) {
+ this.setUnknownProperty(keyName, value);
+ } else {
+
+ if (hasPropertyAccessors) {

- Take note that `"welcome"` is a string and not an object

- /**

+ classNames: ['baz']
+ })
+ view.get('someNonConcatenatedProperty'); // ['baz']
+ view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
+ ```

- ```handlebars
- {{foo}}
- {{partial "nav"}}
- ```
+ ```javascript
+ var view = App.FooBarView.create({
+ classNames: 'baz'
+ })
+ view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
+ ```
- The above example template will render a template named
- "_nav", which has the same context as the parent template
- it's rendered into, so if the "_nav" template also referenced
- `{{foo}}`, it would print the same thing as the `{{foo}}`
- in the above example.
+ Using the `concatenatedProperties` property, we can tell to Ember that mix
+ the content of the properties.
- If a "_nav" template isn't found, the `partial` helper will
- fall back to a template named "nav".
+ In `Ember.View` the `classNameBindings` and `attributeBindings` properties
+ are also concatenated, in addition to `classNames`.
- ## Bound template names
+ This feature is available for you to use throughout the Ember object model,
+ although typical app developers are likely to use it infrequently. Since
+ it changes expectations about behavior of properties, you should properly
+ document its usage in each individual concatenated property (to not
+ mislead your users to think they can override the property in a subclass).
- The parameter supplied to `partial` can also be a path
- to a property containing a template name, e.g.:

- ```html

+ while(obj) {

+ /**
+ In some cases, you may want to annotate computed properties with additional
+ metadata about how they function or what values they operate on. For
+ example, computed property functions may close over variables that are then
+ no longer available for introspection.
- The HTML `class` attribute can be set on the `{{view}}`'s resulting element
- with the `class` or `classNameBindings` options. The `class` option will
- directly set the CSS `class` attribute and will not be passed to
- `Ember.View.create`. `classNameBindings` will be passed to `create` and use
- `Ember.View`'s class name binding functionality:
+ You can pass a hash of these values to a computed property like this:

- ```
+ ```javascript

+ var personId = this.get('personId');

- <span id="ember2" class="ember-view a-custom-class">
- hello.
- </span>
- </div>
- ```
+ ```javascript
+ MyClass.metaForProperty('person');
+ ```
- ### Supplying a different view class
+ This will return the original hash that was passed to `meta()`.

- /**
- `{{yield}}` denotes an area of a template that will be rendered inside
- of another template. It has two main uses:
-
- ### Use with `layout`
- When used in a Handlebars template that is assigned to an `Ember.View`
- instance's `layout` property Ember will render the layout template first,
- inserting the view's own rendered output at the `{{yield}}` location.
-
- An empty `<body>` and the following application code:
-
- ```javascript
- AView = Ember.View.extend({
- classNames: ['a-view-with-layout'],
- layout: Ember.Handlebars.compile('<div class="wrapper">{{yield}}</div>'),
- template: Ember.Handlebars.compile('<span>I am wrapped</span>')
- });
-
- aView = AView.create();
- aView.appendTo('body');
- ```
-
- Will result in the following HTML output:
-
- ```html
- <body>
- <div class='ember-view a-view-with-layout'>
- <div class="wrapper">
- <span>I am wrapped</span>
- </div>
- </div>
- </body>
- ```
+ var EachArray = EmberObject.extend(EmberArray, {
- The `yield` helper cannot be used outside of a template assigned to an
- `Ember.View`'s `layout` property and will throw an error if attempted.
+ init: function(content, keyName, owner) {
+ this._super();
+ this._keyName = keyName;
+ this._owner = owner;
+ this._content = content;
+ },
- ```javascript
- BView = Ember.View.extend({
- classNames: ['a-view-with-layout'],
- template: Ember.Handlebars.compile('{{yield}}')
- });
+ objectAt: function(idx) {
+ var item = this._content.objectAt(idx);
+ return item && get(item, this._keyName);
+ },
- bView = BView.create();
- bView.appendTo('body');
+ length: computed(function() {
+ var content = this._content;
+ return content ? get(content, 'length') : 0;
+ })
- // throws
- // Uncaught Error: assertion failed:
- // You called yield in a template that was not a layout
- ```
+ });
- ### Use with Ember.Component
- When designing components `{{yield}}` is used to denote where, inside the component's
- template, an optional block passed to the component should render:
+ var IS_OBSERVER = /^.+:(before|change)$/;
- ```handlebars
- <!-- application.hbs -->
- {{#labeled-textfield value=someProperty}}
- First name:
- {{/labeled-textfield}}
- ```
+ function addObserverForContentKey(content, keyName, proxy, idx, loc) {
+ var objects = proxy._objects;
+ var guid;
+ if (!objects) objects = proxy._objects = {};
- ```handlebars
- <!-- components/labeled-textfield.hbs -->
- <label>
- {{yield}} {{input value=value}}
- </label>
- ```
+ while(--loc>=idx) {
+ var item = content.objectAt(loc);
+ if (item) {
+ Ember.assert('When using @each to observe the array ' + content + ', the array must return an object', typeOf(item) === 'instance' || typeOf(item) === 'object');
+ addBeforeObserver(item, keyName, proxy, 'contentKeyWillChange');
+ addObserver(item, keyName, proxy, 'contentKeyDidChange');
- Result:
+ // keep track of the index each item was found at so we can map
+ // it back when the obj changes.
+ guid = guidFor(item);
+ if (!objects[guid]) objects[guid] = [];
+ objects[guid].push(loc);

+ An unordered collection of objects.
- var Metamorph = requireModule('metamorph');
+ A Set works a bit like an array except that its items are not ordered. You
+ can create a set to efficiently test for membership for an object. You can
+ also iterate through a set just like an array, even accessing objects by
+ index, however there is no guarantee as to their order.
- function notifyMutationListeners() {
- run.once(View, 'notifyMutationListeners');
- }
+ All Sets are observable via the Enumerable Observer API - which works
+ on any enumerable object including both Sets and Arrays.
- // DOMManager should just abstract dom manipulation between jquery and metamorph
- var DOMManager = {
- remove: function(view) {
- view.morph.remove();
- notifyMutationListeners();
- },
+ ## Creating a Set
- prepend: function(view, html) {
- view.morph.prepend(html);
- notifyMutationListeners();
- },
+ You can create a set like you would most objects using
+ `new Ember.Set()`. Most new sets you create will be empty, but you can
+ also initialize the set with some content by passing an array or other
+ enumerable of objects to the constructor.
- after: function(view, html) {
- view.morph.after(html);
- notifyMutationListeners();
- },
+ Finally, you can pass in an existing set and the set will be copied. You
+ can also create a copy of a set by calling `Ember.Set#copy()`.
- html: function(view, html) {
- view.morph.html(html);
- notifyMutationListeners();
- },
+ ```javascript
+ // creates a new empty set
+ var foundNames = new Ember.Set();
- // This is messed up.
- replace: function(view) {
- var morph = view.morph;
+ // creates a set with four names in it.
+ var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P
- view.transitionTo('preRender');
+ // creates a copy of the names set.
+ var namesCopy = new Ember.Set(names);
- run.schedule('render', this, function renderMetamorphView() {
- if (view.isDestroying) { return; }
+ // same as above.
+ var anotherNamesCopy = names.copy();
+ ```
- view.clearRenderedChildren();
- var buffer = view.renderToBuffer();
+ ## Adding/Removing Objects
- view.invokeRecursively(function(view) {
- view.propertyWillChange('element');
- });
- view.triggerRecursively('willInsertElement');
+ You generally add or remove objects from a set using `add()` or
+ `remove()`. You can add any type of object including primitives such as
+ numbers, strings, and booleans.
- morph.replaceWith(buffer.string());
- view.transitionTo('inDOM');
+ Unlike arrays, objects can only exist one time in a set. If you call `add()`
+ on a set with the same object multiple times, the object will only be added
+ once. Likewise, calling `remove()` with the same object multiple times will
+ remove the object the first time and have no effect on future calls until
+ you add the object to the set again.
- view.invokeRecursively(function(view) {
- view.propertyDidChange('element');
- });
- view.triggerRecursively('didInsertElement');
+ NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do
+ so will be ignored.
- notifyMutationListeners();
- });
- },
+ In addition to add/remove you can also call `push()`/`pop()`. Push behaves
+ just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary
+ object, remove it and return it. This is a good way to use a set as a job
+ queue when you don't care which order the jobs are executed in.
- empty: function(view) {
- view.morph.html("");
- notifyMutationListeners();
- }
- };
+ ## Testing for an Object
- // The `morph` and `outerHTML` properties are internal only
- // and not observable.
+ To test for an object's presence in a set you simply call
+ `Ember.Set#contains()`.
- /**
- @class _Metamorph
+ ## Observing changes
+
+ When using `Ember.Set`, you can observe the `"[]"` property to be
+ alerted whenever the content changes. You can also add an enumerable
+ observer to the set to be notified of specific objects that are added and
+ removed from the set. See [Ember.Enumerable](/api/classes/Ember.Enumerable.html)
+ for more information on enumerables.
+
+ This is often unhelpful. If you are filtering sets of objects, for instance,
+ it is very inefficient to re-filter all of the items each time the set
+ changes. It would be better if you could just adjust the filtered set based
+ on what was changed on the original set. The same issue applies to merging
+ sets, as well.
+
+ ## Other Methods
+
+ `Ember.Set` primary implements other mixin APIs. For a complete reference
+ on the methods you will use with `Ember.Set`, please consult these mixins.
+ The most useful ones will be `Ember.Enumerable` and
+ `Ember.MutableEnumerable` which implement most of the common iterator
+ methods you are used to on Array.
+
+ Note that you can also use the `Ember.Copyable` and `Ember.Freezable`
+ APIs on `Ember.Set` as well. Once a set is frozen it can no longer be
+ modified. The benefit of this is that when you call `frozenCopy()` on it,
+ Ember will avoid making copies of the set. This allows you to write
+ code that can know with certainty when the underlying set data will or
+ will not be modified.

+ than, `Ember.TrackedArray`. It is useful for keeping track of the indexes of
+ items within a filtered array.
- There are several possible target objects for `{{action}}` helpers:
+ @class SubArray
+ @namespace Ember
+ */
+ function SubArray (length) {
+ if (arguments.length < 1) { length = 0; }
- In a typical Ember application, where views are managed through use of the

- to the current route, and then up the route hierarchy.
+ if (length > 0) {
+ this._operations = [new Operation(RETAIN, length)];
+ } else {
+ this._operations = [];
+ }
+ }
- Alternatively, a `target` option can be provided to the helper to change
- which object will receive the method call. This option must be a path
- to an object, accessible in the current context:
- ```handlebars
- {{! the application template }}
- <div {{action "anActionName" target=view}}>
- click me
- </div>
- ```

- ### Disabling the `link-to` helper
- By default `{{link-to}}` is enabled.
- any passed value to `disabled` helper property will disable the `link-to` helper.
+ /**

+ *
+ * Example:
+ *

+ *
+ * ```javascript

+ */
+ helper('findWithAssert', findWithAssert);
- dynamic use: the `disabledWhen` option:
+ /**
+ Causes the run loop to process any pending events. This is used to ensure that
+ any async operations from other helpers (or your assertions) have been processed.
- ```handlebars
- {{#link-to 'photoGallery' disabledWhen=controller.someProperty}}
- Great Hamster Photos
- {{/link-to}}
- ```
+ This is most often used as the return value for the helper functions (see 'click',
+ 'fillIn','visit',etc).
- any passed value to `disabled` will disable it except `undefined`.
- to ensure that only `true` disable the `link-to` helper you can
- override the global behaviour of `Ember.LinkView`.
+ Example:
```javascript
- Ember.LinkView.reopen({
- disabled: Ember.computed(function(key, value) {
- if (value !== undefined) {
- this.set('_isDisabled', value === true);
- }
- return value === true ? get(this, 'disabledClass') : false;
- })
+ Ember.Test.registerAsyncHelper('loginUser', function(app, username, password) {
+ visit('secured/path/here')
+ .fillIn('#username', username)
+ .fillIn('#password', username)
+ .click('.submit')
+
+ return app.testHelpers.wait();
});
- ```
- see "Overriding Application-wide Defaults" for more.
+ @method wait
+ @param {Object} value The value to be returned.
+ @return {RSVP.Promise}
+ */
+ asyncHelper('wait', wait);
+ asyncHelper('andThen', andThen);
- ### Handling `href`
- `{{link-to}}` will use your application's Router to
- fill the element's `href` property with a url that
- matches the path to the supplied `routeName` for your
- routers's configured `Location` scheme, which defaults
- to Ember.HashLocation.
- ### Handling current route
- `{{link-to}}` will apply a CSS class name of 'active'
- when the application's current route matches
- the supplied routeName. For example, if the application's
- current route is 'photoGallery.recent' the following
- use of `{{link-to}}`:
+ /**
+ Returns the currently active route name.
- ```handlebars
- {{#link-to 'photoGallery.recent'}}
- Great Hamster Photos from the last week
- {{/link-to}}
- ```
+ Example:
- will result in
+ ```javascript
+ function validateRouteName(){
+ equal(currentRouteName(), 'some.path', "correct route was transitioned into.");
+ }
- ```html
- <a href="/hamster-photos/this-week" class="active">
- Great Hamster Photos
- </a>
- ```
+ visit('/some/path').then(validateRouteName)
+ ```
- The CSS class name used for active classes can be customized
- for a single use of `{{link-to}}` by passing an `activeClass`
- option:
+ @method currentRouteName
+ @return {Object} The name of the currently active route.
+ @since 1.5.0
+ */
+ helper('currentRouteName', currentRouteName);
- ```handlebars
- {{#link-to 'photoGallery.recent' activeClass="current-url"}}
- Great Hamster Photos from the last week
- {{/link-to}}
- ```
+ /**
+ Returns the current path.
- ```html
- <a href="/hamster-photos/this-week" class="current-url">
- Great Hamster Photos

- To override this option for your entire application, see
- "Overriding Application-wide Defaults".
+ ```javascript
+ function validateURL(){
+ equal(currentPath(), 'some.path.index', "correct path was transitioned into.");
+ }
- ### Supplying a model
- An optional model argument can be used for routes whose
- paths contain dynamic segments. This argument will become
- the model context of the linked route:
+ click('#some-link-id').then(validateURL);
+ ```
- ```javascript
- App.Router.map(function() {
- this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
- });
- ```
+ @method currentPath
+ @return {Object} The currently active path.
+ @since 1.5.0
+ */

- {{/link-to}}
- ```
+ /**
+ Returns the current URL.
- ```html
- <a href="/hamster-photos/42">
- Tomster
- </a>
- ```
+ Example:
- ### Supplying multiple models
- For deep-linking to route paths that contain multiple
- dynamic segments, multiple model arguments can be used.
- As the router transitions through the route path, each
- supplied model argument will become the context for the
- route with the dynamic segments:
+ ```javascript
+ function validateURL(){
+ equal(currentURL(), '/some/path', "correct URL was transitioned into.");
+ }
- ```javascript
- App.Router.map(function() {
- this.resource("photoGallery", {path: "hamster-photos/:photo_id"}, function() {
- this.route("comment", {path: "comments/:comment_id"});
- });
- });
- ```
- This argument will become the model context of the linked route:
+ click('#some-link-id').then(validateURL);
+ ```
- ```handlebars
- {{#link-to 'photoGallery.comment' aPhoto comment}}
- {{comment.body}}
- {{/link-to}}
- ```
+ @method currentURL
+ @return {Object} The currently active URL.
+ @since 1.5.0
+ */
+ helper('currentURL', currentURL);
- ```html
- <a href="/hamster-photos/42/comment/718">
- A+++ would snuggle again.
- </a>
- ```
+ /**
+ Triggers the given DOM event on the element identified by the provided selector.
- ### Supplying an explicit dynamic segment value
- If you don't have a model object available to pass to `{{link-to}}`,
- an optional string or integer argument can be passed for routes whose
- paths contain dynamic segments. This argument will become the value
- of the dynamic segment:
+ Example:
```javascript
- App.Router.map(function() {
- this.resource("photoGallery", {path: "hamster-photos/:photo_id"});
- });
+ triggerEvent('#some-elem-id', 'blur');
```
- ```handlebars
- {{#link-to 'photoGallery' aPhotoId}}
- {{aPhoto.title}}
- {{/link-to}}
- ```
+ This is actually used internally by the `keyEvent` helper like so:
- ```html
- <a href="/hamster-photos/42">
- Tomster
- </a>
+ ```javascript
+ triggerEvent('#some-elem-id', 'keypress', { keyCode: 13 });
```
- When transitioning into the linked route, the `model` hook will
- be triggered with parameters including this passed identifier.
-
- ### Allowing Default Action
-
- By default the `{{link-to}}` helper prevents the default browser action
- by calling `preventDefault()` as this sort of action bubbling is normally
- handled internally and we do not want to take the browser to a new URL (for
- example).
-
- If you need to override this behavior specify `preventDefault=false` in
- your template:
+ @method triggerEvent
+ @param {String} selector jQuery selector for finding element on the DOM
+ @param {String} [context] jQuery selector that will limit the selector
+ argument to find only within the context's children
+ @param {String} type The event type to be triggered.
+ @param {Object} [options] The options to be passed to jQuery.Event.
+ @return {RSVP.Promise}
+ @since 1.5.0
+ */
+ asyncHelper('triggerEvent', triggerEvent);

- {{aPhotoId.title}}

- ```
+ var name = 'deferReadiness in `testing` mode';
- ### Overriding attributes
- You can override any given property of the Ember.LinkView
- that is generated by the `{{link-to}}` helper by passing
- key/value pairs, like so:
+ onLoad('Ember.Application', function(Application) {
+ if (!Application.initializers[name]) {

- ```handlebars
- {{#link-to aPhoto tagName='li' title='Following this link will change your life' classNames='pic sweet'}}

- See [Ember.LinkView](/api/classes/Ember.LinkView.html) for a
- complete list of overrideable properties. Be sure to also
- check out inherited properties of `LinkView`.
+ var Test, requests;
- ### Overriding Application-wide Defaults
- ``{{link-to}}`` creates an instance of Ember.LinkView
- for rendering. To override options for your entire
- application, reopen Ember.LinkView and supply the
- desired values:
+ function incrementAjaxPendingRequests(_, xhr){
+ requests.push(xhr);
+ Test.pendingAjaxRequests = requests.length;
+ }
- ``` javascript
- Ember.LinkView.reopen({
- activeClass: "is-active",

+ for (var i=0;i<requests.length;i++) {
+ if (xhr === requests[i]) {
+ requests.splice(i, 1);
+ }
+ }
+ Test.pendingAjaxRequests = requests.length;
+ }
- It is also possible to override the default event in
- this manner:
+ /**

- Using `HashLocation` results in URLs with a `#` (hash sign) separating the

+ };
- The `willTransition` action is fired at the beginning of any

- redirecting `transitionTo`, since `willTransition` doesn't
- fire when there is already a transition underway. If you want

- ### `error`
+ var a_slice = Array.prototype.slice;
- When attempting to transition into a route, any of the hooks
- may return a promise that rejects, at which point an `error`
- action will be fired on the partially-entered routes, allowing
- for per-route error handling logic, or shared error handling
- logic defined on a parent route.
+ /**
+ @module ember
+ @submodule ember-views
+ */
- Here is an example of an error handler that will be invoked
- for rejected promises from the various hooks on the route,
- as well as any unhandled errors from child routes:
+ /**
+ An `Ember.Component` is a view that is completely
+ isolated. Property access in its templates go
+ to the view object and actions are targeted at
+ the view object. There is no access to the
+ surrounding context or outer controller; all
+ contextual information must be passed in.
- ```js
- App.AdminRoute = Ember.Route.extend({
- beforeModel: function() {
- return Ember.RSVP.reject("bad things!");
- },
+ The easiest way to create an `Ember.Component` is via
+ a template. If you name a template
+ `components/my-foo`, you will be able to use
+ `{{my-foo}}` in other templates, which will make
+ an instance of the isolated component.
- actions: {
- error: function(error, transition) {
- // Assuming we got here due to the error in `beforeModel`,
- // we can expect that error === "bad things!",
- // but a promise model rejecting would also
- // call this hook, as would any errors encountered
- // in `afterModel`.
+ ```handlebars
+ {{app-profile person=currentUser}}
+ ```
- // The `error` hook is also provided the failed
- // `transition`, which can be stored and later
- // `.retry()`d if desired.
+ ```handlebars
+ <!-- app-profile template -->
+ <h1>{{person.title}}</h1>
+ <img {{bind-attr src=person.avatar}}>
+ <p class='signature'>{{person.signature}}</p>
+ ```
- this.transitionTo('login');
- }
- }
- });
- ```
+ You can use `yield` inside a template to
+ include the **contents** of any block attached to
+ the component. The block will be executed in the
+ context of the surrounding context or outer controller:
- `error` actions that bubble up all the way to `ApplicationRoute`
- will fire a default error handler that logs the error. You can
- specify your own global default error handler by overriding the
- `error` handler on `ApplicationRoute`:
+ ```handlebars
+ {{#app-profile person=currentUser}}
+ <p>Admin mode</p>
+ {{! Executed in the controller's context. }}
+ {{/app-profile}}
+ ```
- ```js
- App.ApplicationRoute = Ember.Route.extend({
- actions: {
- error: function(error, transition) {
- this.controllerFor('banner').displayError(error.message);
- }
- }
- });
- ```
+ ```handlebars
+ <!-- app-profile template -->
+ <h1>{{person.title}}</h1>
+ {{! Executed in the components context. }}
+ {{yield}} {{! block contents }}
+ ```
- @property actions
- @type Hash
- @default null
- */

+ If you want to customize the component, in order to

- Simple Transition Example
```javascript

- this.route("fourOhFour", { path: "*:"});
- });
-
- App.IndexRoute = Ember.Route.extend({

+ if (this.get('isPlaying')) {
+ this.sendAction('play');
+ } else {
+ this.sendAction('stop');
}
}
});
```
- Transition to a nested route
+ When used inside a template these component actions are configured to
+ trigger actions in the outer application context:
- ```javascript
- App.Router.map(function() {
- this.resource('articles', { path: '/articles' }, function() {
- this.route('new');
- });
- });
+ ```handlebars
+ {{! application.hbs }}
+ {{play-button play="musicStarted" stop="musicStopped"}}
+ ```
- App.IndexRoute = Ember.Route.extend({
+ When the component receives a browser `click` event it translate this
+ interaction into application-specific semantics ("play" or "stop") and
+ triggers the specified action name on the controller for the template
+ where the component is used:
+
+
+ ```javascript
+ App.ApplicationController = Ember.Controller.extend({
actions: {
- transitionToNewArticle: function() {
- this.transitionTo('articles.new');
+ musicStarted: function(){
+ // called when the play button is clicked
+ // and the music started playing
+ },
+ musicStopped: function(){
+ // called when the play button is clicked
+ // and the music stopped playing
}
}
});
```
- Multiple Models Example
+ If no action name is passed to `sendAction` a default name of "action"
+ is assumed.
```javascript
- App.Router.map(function() {
- this.route("index");
- this.resource('breakfast', {path:':breakfastId'}, function(){

- });

- /**
- This hook is the first of the route entry validation hooks
- called when an attempt is made to transition into a route
- or one of its children. It is called before `model` and
- `afterModel`, and is appropriate for cases when:
+ ## Setting Initial Child Views
- 1) A decision can be made to redirect elsewhere without
- needing to resolve the model first.
- 2) Any async operations need to occur first before the
- model is attempted to be resolved.
+ The initial array of child views can be set in one of two ways. You can
+ provide a `childViews` property at creation time that contains instance of
+ `Ember.View`:
- This hook is provided the current `transition` attempt
- as a parameter, which can be used to `.abort()` the transition,
- save it for a later `.retry()`, or retrieve values set
- on it from a previous hook. You can also just call
- `this.transitionTo` to another route to implicitly
- abort the `transition`.
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ childViews: [Ember.View.create(), Ember.View.create()]
+ });
+ ```
- You can return a promise from this hook to pause the
- transition until the promise resolves (or rejects). This could
- be useful, for instance, for retrieving async code from
- the server that is required to enter a route.
+ You can also provide a list of property names whose values are instances of
+ `Ember.View`:
- ```js
- App.PostRoute = Ember.Route.extend({
- beforeModel: function(transition) {
- if (!App.Post) {
- return Ember.$.getScript('/models/post.js');
- }
- }
- });
- ```
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ childViews: ['aView', 'bView', 'cView'],
+ aView: Ember.View.create(),
+ bView: Ember.View.create(),
+ cView: Ember.View.create()
+ });
+ ```
- If `App.Post` doesn't exist in the above example,
- `beforeModel` will use jQuery's `getScript`, which
- returns a promise that resolves after the server has
- successfully retrieved and executed the code from the
- server. Note that if an error were to occur, it would
- be passed to the `error` hook on `Ember.Route`, but
- it's also possible to handle errors specific to
- `beforeModel` right from within the hook (to distinguish
- from the shared error handling behavior of the `error`
- hook):
+ The two strategies can be combined:
- ```js
- App.PostRoute = Ember.Route.extend({
- beforeModel: function(transition) {
- if (!App.Post) {
- var self = this;
- return Ember.$.getScript('post.js').then(null, function(e) {
- self.transitionTo('help');
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ childViews: ['aView', Ember.View.create()],
+ aView: Ember.View.create()
+ });
+ ```
- // Note that the above transitionTo will implicitly
- // halt the transition. If you were to return
- // nothing from this promise reject handler,
- // according to promise semantics, that would
- // convert the reject into a resolve and the
- // transition would continue. To propagate the
- // error so that it'd be handled by the `error`
- // hook, you would have to either
- return Ember.RSVP.reject(e);
- });
- }
- }
- });
- ```
+ Each child view's rendering will be inserted into the container's rendered
+ HTML in the same order as its position in the `childViews` property.
- @method beforeModel
- @param {Transition} transition
- @param {Object} queryParams the active query params for this route
- @return {Promise} if the value returned from this hook is
- a promise, the transition will pause until the transition
- resolves. Otherwise, non-promise return values are not

- /**
- This hook is called after this route's model has resolved.
- It follows identical async/promise semantics to `beforeModel`
- but is provided the route's resolved model in addition to
- the `transition`, and is therefore suited to performing
- logic that can only take place after the model has already
- resolved.

- of transition-pausing semantics when a promise is returned
- from this hook.
+ Given an empty `<body>` the following code
- @method afterModel
- @param {Object} resolvedModel the value returned from `model`,
- or its resolved value if it was a promise
- @param {Transition} transition
- @param {Object} queryParams the active query params for this handler
- @return {Promise} if the value returned from this hook is

- resolves. Otherwise, non-promise return values are not
- utilized in any way.

- `redirect` and `afterModel` behave very similarly and are
- called almost at the same time, but they have an important
- distinction in the case that, from one of these hooks, a
- redirect into a child route of this route occurs: redirects
- from `afterModel` essentially invalidate the current attempt
- to enter this route, and will result in this route's `beforeModel`,
- `model`, and `afterModel` hooks being fired again within
- the new, redirecting transition. Redirects that occur within
- the `redirect` hook, on the other hand, will _not_ cause
- these hooks to be fired again the second time around; in
- other words, by the time the `redirect` hook has been called,
- both the resolved model and attempted entry into this route
- are considered to be fully validated.

+ Given an empty `<body>` the following code
- By default, if your route has a dynamic segment ending in `_id`:
+ ```javascript
+ aContainer = Ember.ContainerView.create({
+ classNames: ['the-container'],
+ childViews: ['aView', 'bView'],
+ aView: Ember.View.create({
+ template: Ember.Handlebars.compile("A")
+ }),
+ bView: Ember.View.create({
+ template: Ember.Handlebars.compile("B")
+ })
+ });
- * The model class is determined from the segment (`post_id`'s
- class is `App.Post`)
- * The find method is called on the model class with the value of
- the dynamic segment.
+ aContainer.appendTo('body');
+ ```
- Note that for routes with dynamic segments, this hook is only
- executed when entered via the URL. If the route is entered
- through a transition (e.g. when using the `link-to` Handlebars
- helper), then a model context is already provided and this hook
- is not called. Routes without dynamic segments will always
- execute the model hook.
+ Results in the HTML
- This hook follows the asynchronous/promise semantics
- described in the documentation for `beforeModel`. In particular,
- if a promise returned from `model` fails, the error will be
- handled by the `error` hook on `Ember.Route`.
+ ```html
+ <div class="ember-view the-container">
+ <div class="ember-view">A</div>
+ <div class="ember-view">B</div>
+ </div>
+ ```
- Example
+ Adding a view
- ```js
- App.PostRoute = Ember.Route.extend({
- model: function(params) {
- return App.Post.find(params.post_id);
- }
- });
- ```
+ ```javascript
+ AnotherViewClass = Ember.View.extend({
+ template: Ember.Handlebars.compile("Another view")
+ });
- @method model
- @param {Object} params the parameters extracted from the URL
- @param {Transition} transition
- @param {Object} queryParams the query params for this route
- @return {Object|Promise} the model for this route. If
- a promise is returned, the transition will pause until
- the promise resolves, and the resolved value of the promise
- will be used as the model for this route.

- If you implement the `setupController` hook in your Route, it will

- `_super`:

+ forEach(views, function(view) {
+ set(view, '_parentView', parentView);
- ```js
- App.PhotosRoute = Ember.Route.extend({

- return App.Photo.find();
- },
+ if (!view.container && parentView) {
+ set(view, 'container', parentView.container);

- // Call _super for default behavior

- // Implement your custom setup after
- this.controllerFor('application').set('showingPhotos', true);
+ if (!get(view, 'templateData')) {
+ set(view, 'templateData', templateData);
}
});
- ```
-
- This means that your template will get a proxy for the model as its
- context, and you can act as though the model itself was the context.
-
- The provided controller will be one resolved based on the name
- of this route.
-
- If no explicit controller is defined, Ember will automatically create
- an appropriate controller for the model.
+ },
- * if the model is an `Ember.Array` (including record arrays from Ember
- Data), the controller is an `Ember.ArrayController`.
- * otherwise, the controller is an `Ember.ObjectController`.
+ currentView: null,
- As an example, consider the router:
+ _currentViewWillChange: beforeObserver('currentView', function() {

- _lookupActiveView: function(templateName) {
- var active = this._activeViews[templateName];
- return active && active[0];
- },
+ If the return value of an `attributeBindings` monitored property is a boolean

+ its value:
- _connectActiveView: function(templateName, view) {
- var existing = this._activeViews[templateName];
+ ```javascript
+ MyTextInput = Ember.View.extend({
+ tagName: 'input',

+ ```
- this._activeViews[templateName] = [view, disconnect];

+ ```
- if ('string' === typeof location && this.container) {
- var resolvedLocation = this.container.lookup('location:' + location);
+ Updates to the the property of an attribute binding will result in automatic
+ update of the HTML attribute in the view's rendered HTML representation.
- if ('undefined' !== typeof resolvedLocation) {
- location = set(this, 'location', resolvedLocation);
- } else {
- // Allow for deprecated registration of custom location API's
- var options = {implementation: location};
+ `attributeBindings` is a concatenated property. See [Ember.Object](/api/classes/Ember.Object.html)
+ documentation for more information about concatenated properties.
- location = set(this, 'location', EmberLocation.create(options));
- }
- }
+ ## Templates
+
+ The HTML contents of a view's rendered representation are determined by its
+ template. Templates can be any function that accepts an optional context
+ parameter and returns a string of HTML that will be inserted within the
+ view's tag. Most typically in Ember this function will be a compiled
+ `Ember.Handlebars` template.
+
+ ```javascript
+ AView = Ember.View.extend({
+ template: Ember.Handlebars.compile('I am the template')
+ });
+ ```
- if (typeof rootURL === 'string') {
- location.rootURL = rootURL;
- }
+ Will result in view instances with an HTML representation of:
- // ensure that initState is called AFTER the rootURL is set on
- // the location instance
- if (typeof location.initState === 'function') { location.initState(); }
- },
+ ```html
+ <div id="ember1" class="ember-view">I am the template</div>
+ ```
- _getHandlerFunction: function() {
- var seen = {}, container = this.container,
- DefaultRoute = container.lookupFactory('route:basic'),
- self = this;
+ Within an Ember application is more common to define a Handlebars templates as
+ part of a page:
- return function(name) {
- var routeName = 'route:' + name,
- handler = container.lookup(routeName);
+ ```html
+ <script type='text/x-handlebars' data-template-name='some-template'>
+ Hello
+ </script>
+ ```
- if (seen[name]) { return handler; }
+ And associate it by name using a view's `templateName` property:
- seen[name] = true;
+ ```javascript
+ AView = Ember.View.extend({
+ templateName: 'some-template'
+ });
+ ```
- if (!handler) {
- container.register(routeName, DefaultRoute.extend());
- handler = container.lookup(routeName);
+ If you have nested resources, your Handlebars template will look like this:
- if (get(self, 'namespace.LOG_ACTIVE_GENERATION')) {
- Ember.Logger.info("generated -> " + routeName, { fullName: routeName });
- }
- }
+ ```html
+ <script type='text/x-handlebars' data-template-name='posts/new'>
+ <h1>New Post</h1>
+ </script>
+ ```
- handler.routeName = name;
- return handler;
- };
- },
+ And `templateName` property:
- _setupRouter: function(router, location) {
- var lastURL, emberRouter = this;
+ ```javascript
+ AView = Ember.View.extend({
+ templateName: 'posts/new'
+ });
+ ```
- router.getHandler = this._getHandlerFunction();
+ Using a value for `templateName` that does not have a Handlebars template
+ with a matching `data-template-name` attribute will throw an error.
- var doUpdateURL = function() {
- location.setURL(lastURL);
- };
+ For views classes that may have a template later defined (e.g. as the block
+ portion of a `{{view}}` Handlebars helper call in another template or in
+ a subclass), you can provide a `defaultTemplate` property set to compiled
+ template function. If a template is not later provided for the view instance
+ the `defaultTemplate` value will be used:
- router.updateURL = function(path) {
- lastURL = path;
- run.once(doUpdateURL);
- };
+ ```javascript
+ AView = Ember.View.extend({
+ defaultTemplate: Ember.Handlebars.compile('I was the default'),
+ template: null,
+ templateName: null
+ });
+ ```
- if (location.replaceURL) {
- var doReplaceURL = function() {
- location.replaceURL(lastURL);
- };
+ Will result in instances with an HTML representation of:
- router.replaceURL = function(path) {
- lastURL = path;
- run.once(doReplaceURL);
- };
- }
+ ```html
+ <div id="ember1" class="ember-view">I was the default</div>
+ ```
- router.didTransition = function(infos) {
- emberRouter.didTransition(infos);
- };
- },
+ If a `template` or `templateName` is provided it will take precedence over
+ `defaultTemplate`:
- _doTransition: function(method, args) {
- // Normalize blank route to root URL.
- args = slice.call(args);
- args[0] = args[0] || '/';
+ ```javascript
+ AView = Ember.View.extend({
+ defaultTemplate: Ember.Handlebars.compile('I was the default')
+ });
- var name = args[0], self = this,
- isQueryParamsOnly = false, queryParams;
+ aView = AView.create({
+ template: Ember.Handlebars.compile('I was the template, not default')
+ });
+ ```
- if (Ember.FEATURES.isEnabled("query-params-new")) {
+ Will result in the following HTML representation when rendered:
- var possibleQueryParamArg = args[args.length - 1];
- if (possibleQueryParamArg && possibleQueryParamArg.hasOwnProperty('queryParams')) {
- if (args.length === 1) {
- isQueryParamsOnly = true;
- name = null;
- }
- queryParams = args[args.length - 1].queryParams;
- }
- }
+ ```html
+ <div id="ember1" class="ember-view">I was the template, not default</div>
+ ```
- if (!isQueryParamsOnly && name.charAt(0) !== '/') {
- Ember.assert("The route " + name + " was not found", this.router.hasRoute(name));
- }
+ ## View Context
- if (queryParams) {
- // router.js expects queryParams to be passed in in
- // their final serialized form, so we need to translate.
+ The default context of the compiled template is the view's controller:
- if (!name) {
- // Need to determine destination route name.
- var handlerInfos = this.router.activeTransition ?
- this.router.activeTransition.state.handlerInfos :
- this.router.state.handlerInfos;
- name = handlerInfos[handlerInfos.length - 1].name;
- args.unshift(name);
- }
+ ```javascript
+ AView = Ember.View.extend({
+ template: Ember.Handlebars.compile('Hello {{excitedGreeting}}')
+ });
- var qpCache = this._queryParamsFor(name), qps = qpCache.qps;
+ aController = Ember.Object.create({
+ firstName: 'Barry',
+ excitedGreeting: function() {
+ return this.get("content.firstName") + "!!!"
+ }.property()
+ });
- var finalParams = {};
- for (var key in queryParams) {
- if (!queryParams.hasOwnProperty(key)) { continue; }
- var inputValue = queryParams[key],
- qp = qpCache.map[key];
+ aView = AView.create({
+ controller: aController
+ });
+ ```
- if (!qp) {
- throw new EmberError("Unrecognized query param " + key + " provided as transition argument");
- }
- finalParams[qp.urlKey] = qp.route.serializeQueryParam(inputValue, qp.urlKey, qp.type);
- }
+ Will result in an HTML representation of:
- // Perform any necessary serialization.
- args[args.length-1].queryParams = finalParams;
- }
+ ```html
+ <div id="ember1" class="ember-view">Hello Barry!!!</div>
+ ```
- var transitionPromise = this.router[method].apply(this.router, args);
+ A context can also be explicitly supplied through the view's `context`
+ property. If the view has neither `context` nor `controller` properties, the
+ `parentView`'s context will be used.
- transitionPromise.then(null, function(error) {
- if (error && error.name === "UnrecognizedURLError") {
- Ember.assert("The URL '" + error.message + "' did not match any routes in your application");
- }
- }, 'Ember: Check for Router unrecognized URL error');
+ ## Layouts
- // We want to return the configurable promise object
- // so that callers of this function can use `.method()` on it,
- // which obviously doesn't exist for normal RSVP promises.
- return transitionPromise;
- },
+ Views can have a secondary template that wraps their main template. Like
+ primary templates, layouts can be any function that accepts an optional
+ context parameter and returns a string of HTML that will be inserted inside
+ view's tag. Views whose HTML element is self closing (e.g. `<input />`)
+ cannot have a layout and this property will be ignored.
- _queryParamsFor: function(leafRouteName) {
- if (this._qpCache[leafRouteName]) {
- return this._qpCache[leafRouteName];
- }
+ Most typically in Ember a layout will be a compiled `Ember.Handlebars`
+ template.
- var map = {}, qps = [], qpCache = this._qpCache[leafRouteName] = {
- map: map,
- qps: qps
- };
+ A view's layout can be set directly with the `layout` property or reference
+ an existing Handlebars template by name with the `layoutName` property.
- var routerjs = this.router,
- recogHandlerInfos = routerjs.recognizer.handlersFor(leafRouteName);
+ A template used as a layout must contain a single use of the Handlebars
+ `{{yield}}` helper. The HTML contents of a view's rendered `template` will be
+ inserted at this location:
- for (var i = 0, len = recogHandlerInfos.length; i < len; ++i) {
- var recogHandler = recogHandlerInfos[i],
- route = routerjs.getHandler(recogHandler.handler),
- qpMeta = get(route, '_qp');
+ ```javascript
+ AViewWithLayout = Ember.View.extend({
+ layout: Ember.Handlebars.compile("<div class='my-decorative-class'>{{yield}}</div>"),
+ template: Ember.Handlebars.compile("I got wrapped")
+ });
+ ```
- if (!qpMeta) { continue; }
+ Will result in view instances with an HTML representation of:
- merge(map, qpMeta.map);
- qps.push.apply(qps, qpMeta.qps);
- }
+ ```html
+ <div id="ember1" class="ember-view">

+ as the first argument to the method and an `Ember.View` object as the
+ second. The `Ember.View` will be the view whose rendered HTML was interacted
+ with. This may be the view with the `eventManager` property or one of its

+ runSharedModelHook: function(payload, hookName, args) {
+ this.log(payload, "calling " + hookName + " hook");
- Each Ember app has one and only one `Ember.Application` object. In fact, the
- very first thing you should do in your application is create the instance:
+ if (this.queryParams) {
+ args.push(this.queryParams);
+ }
+ args.push(payload);
- ```javascript
- window.App = Ember.Application.create();
- ```
+ var result = applyHook(this.handler, hookName, args);
- Typically, the application object is the only global variable. All other
- classes in your app should be properties on the `Ember.Application` instance,
- which highlights its first role: a global namespace.
+ if (result && result.isTransition) {
+ result = null;
+ }
- For example, if you define a view class, it might look like this:
+ return Promise.resolve(result, this.promiseLabel("Resolve value returned from one of the model hooks"));
+ },
- ```javascript
- App.MyView = Ember.View.extend();
- ```
+ // overridden by subclasses
+ getModel: null,
- By default, calling `Ember.Application.create()` will automatically initialize
- your application by calling the `Ember.Application.initialize()` method. If
- you need to delay initialization, you can call your app's `deferReadiness()`
- method. When you are ready for your app to be initialized, call its
- `advanceReadiness()` method.
+ checkForAbort: function(shouldContinue, promiseValue) {
+ return Promise.resolve(shouldContinue(), this.promiseLabel("Check for abort")).then(function() {
+ // We don't care about shouldContinue's resolve value;
+ // pass along the original value passed to this fn.
+ return promiseValue;
+ }, null, this.promiseLabel("Ignore fulfillment value and continue"));
+ },
- You can define a `ready` method on the `Ember.Application` instance, which
- will be run by Ember when the application is initialized.
+ stashResolvedModel: function(payload, resolvedModel) {
+ payload.resolvedModels = payload.resolvedModels || {};
+ payload.resolvedModels[this.name] = resolvedModel;
+ },
- Because `Ember.Application` inherits from `Ember.Namespace`, any classes
- you create will have useful string representations when calling `toString()`.
- See the `Ember.Namespace` documentation for more information.
+ becomeResolved: function(payload, resolvedContext) {
+ var params = this.serialize(resolvedContext);
- While you can think of your `Ember.Application` as a container that holds the
- other classes in your application, there are several other responsibilities
- going on under-the-hood that you may want to understand.
+ if (payload) {
+ this.stashResolvedModel(payload, resolvedContext);
+ payload.params = payload.params || {};
+ payload.params[this.name] = params;
+ }
- ### Event Delegation
+ return this.factory('resolved', {
+ context: resolvedContext,
+ name: this.name,
+ handler: this.handler,
+ params: params
+ });
+ },
- Ember uses a technique called _event delegation_. This allows the framework
- to set up a global, shared event listener instead of requiring each view to
- do it manually. For example, instead of each view registering its own
- `mousedown` listener on its associated element, Ember sets up a `mousedown`
- listener on the `body`.
+ shouldSupercede: function(other) {
+ // Prefer this newer handlerInfo over `other` if:
+ // 1) The other one doesn't exist
+ // 2) The names don't match
+ // 3) This handler has a context that doesn't match
+ // the other one (or the other one doesn't have one).
+ // 4) This handler has parameters that don't match the other.
+ if (!other) { return true; }
- If a `mousedown` event occurs, Ember will look at the target of the event and
- start walking up the DOM node tree, finding corresponding views and invoking
- their `mouseDown` method as it goes.
+ var contextsMatch = (other.context === this.context);
+ return other.name !== this.name ||
+ (this.hasOwnProperty('context') && !contextsMatch) ||
+ (this.hasOwnProperty('params') && !paramsMatch(this.params, other.params));
+ }
+ };
- `Ember.Application` has a number of default events that it listens for, as
- well as a mapping from lowercase events to camel-cased view method names. For
- example, the `keypress` event causes the `keyPress` method on the view to be
- called, the `dblclick` event causes `doubleClick` to be called, and so on.
+ function paramsMatch(a, b) {
+ if ((!a) ^ (!b)) {
+ // Only one is null.
+ return false;
+ }
- If there is a bubbling browser event that Ember does not listen for by
- default, you can specify custom events and their corresponding view method
- names by setting the application's `customEvents` property:
+ if (!a) {
+ // Both must be null.
+ return true;
+ }
- ```javascript
- App = Ember.Application.create({
- customEvents: {
- // add support for the paste event
- paste: "paste"
+ // Note: this assumes that both params have the same
+ // number of keys, but since we're comparing the
+ // same handlers, they should.
+ for (var k in a) {
+ if (a.hasOwnProperty(k) && a[k] !== b[k]) {
+ return false;
}
- });
- ```
+ }
+ return true;
+ }
- By default, the application sets up these event listeners on the document
- body. However, in cases where you are embedding an Ember application inside
- an existing page, you may want it to set up the listeners on an element
- inside the body.

+ });

+ "use strict";
+ var ResolvedHandlerInfo = __dependency1__["default"];
+ var UnresolvedHandlerInfoByObject = __dependency2__["default"];
+ var UnresolvedHandlerInfoByParam = __dependency3__["default"];
- For example, if only events inside a DOM element with the ID of `ember-app`
- should be delegated, set your application's `rootElement` property:
+ handlerInfoFactory.klasses = {
+ resolved: ResolvedHandlerInfo,
+ param: UnresolvedHandlerInfoByParam,
+ object: UnresolvedHandlerInfoByObject
+ };
- ```javascript
- window.App = Ember.Application.create({
- rootElement: '#ember-app'
- });
- ```
+ function handlerInfoFactory(name, props) {
+ var Ctor = handlerInfoFactory.klasses[name],
+ handlerInfo = new Ctor(props || {});
+ handlerInfo.factory = handlerInfoFactory;
+ return handlerInfo;
+ }
- The `rootElement` can be either a DOM element or a jQuery-compatible selector
- string. Note that *views appended to the DOM outside the root element will
- not receive events.* If you specify a custom root element, make sure you only
- append views inside it!

- To learn more about the advantages of event delegation and the Ember view
- layer, and a list of the event listeners that are setup by default, visit the
- [Ember View Layer guide](http://emberjs.com/guides/understanding-ember/the-view-layer/#toc_event-delegation).
+ var ResolvedHandlerInfo = subclass(HandlerInfo, {
+ resolve: function(shouldContinue, payload) {
+ // A ResolvedHandlerInfo just resolved with itself.
+ if (payload && payload.resolvedModels) {
+ payload.resolvedModels[this.name] = this.context;
+ }
+ return Promise.resolve(this, this.promiseLabel("Resolve"));
+ },
- ### Initializers
+ getUnresolved: function() {
+ return this.factory('param', {
+ name: this.name,
+ handler: this.handler,
+ params: this.params
+ });
+ },
- Libraries on top of Ember can add initializers, like so:
+ isResolved: true
+ });
- ```javascript
- Ember.Application.initializer({
- name: 'api-adapter',
+ __exports__["default"] = ResolvedHandlerInfo;
+ });
+enifed("router/handler-info/unresolved-handler-info-by-object",
+ ["../handler-info","router/utils","rsvp/promise","exports"],
+ function(__dependency1__, __dependency2__, __dependency3__, __exports__) {
+ "use strict";
+ var HandlerInfo = __dependency1__["default"];
+ var merge = __dependency2__.merge;
+ var subclass = __dependency2__.subclass;
+ var promiseLabel = __dependency2__.promiseLabel;
+ var isParam = __dependency2__.isParam;
+ var Promise = __dependency3__["default"];
- initialize: function(container, application) {
- application.register('api-adapter:main', ApiAdapter);
- }
- });
- ```
+ var UnresolvedHandlerInfoByObject = subclass(HandlerInfo, {
+ getModel: function(payload) {
+ this.log(payload, this.name + ": resolving provided model");
+ return Promise.resolve(this.context);
+ },
- Initializers provide an opportunity to access the container, which
- organizes the different components of an Ember application. Additionally
- they provide a chance to access the instantiated application. Beyond
- being used for libraries, initializers are also a great way to organize
- dependency injection or setup in your own application.
+ initialize: function(props) {
+ this.names = props.names || [];
+ this.context = props.context;
+ },
- ### Routing
+ /**
+ @private
- In addition to creating your application's router, `Ember.Application` is
- also responsible for telling the router when to start routing. Transitions
- between routes can be logged with the `LOG_TRANSITIONS` flag, and more
- detailed intra-transition logging can be logged with
- the `LOG_TRANSITIONS_INTERNAL` flag:
+ Serializes a handler using its custom `serialize` method or
+ by a default that looks up the expected property name from
+ the dynamic segment.
- ```javascript
- window.App = Ember.Application.create({
- LOG_TRANSITIONS: true, // basic logging of successful transitions
- LOG_TRANSITIONS_INTERNAL: true // detailed logging of all routing steps
- });
- ```
+ @param {Object} model the model to be serialized for this handler
+ */
+ serialize: function(_model) {
+ var model = _model || this.context,
+ names = this.names,
+ handler = this.handler;
- By default, the router will begin trying to translate the current URL into
- application state once the browser emits the `DOMContentReady` event. If you
- need to defer routing, you can call the application's `deferReadiness()`
- method. Once routing can begin, call the `advanceReadiness()` method.
+ var object = {};
+ if (isParam(model)) {
+ object[names[0]] = model;
+ return object;
+ }
- If there is any setup required before routing begins, you can implement a
- `ready()` method on your app that will be invoked immediately before routing
- begins.
- ```
+ // Use custom serialize if it exists.
+ if (handler.serialize) {
+ return handler.serialize(model, names);
+ }
- @class Application
- @namespace Ember
- @extends Ember.Namespace

+ } else {

- When Ember instantiates a controller, view, or other framework component
- it can attach a dependency to that component. This is often used to
- provide services to a set of framework components.

- An example of providing a session object to all controllers:
+ var targetHandler = targetHandlerInfos[targetHandlerInfos.length - 1].name;
+ var recogHandlers = this.recognizer.handlersFor(targetHandler);
- ```javascript
- var App = Ember.Application.create(),
- Session = Ember.Object.extend({ isAuthenticated: false });
+ var index = 0;
+ for (len = recogHandlers.length; index < len; ++index) {
+ handlerInfo = targetHandlerInfos[index];
+ if (handlerInfo.name === handlerName) { break; }
+ }
- // A factory must be registered before it can be injected
- App.register('session:main', Session);
+ if (index === recogHandlers.length) {
+ // The provided route name isn't even in the route hierarchy.
+ return false;
+ }
- // Inject 'session:main' onto all factories of the type 'controller'
- // with the name 'session'
- App.inject('controller', 'session', 'session:main');
+ var state = new TransitionState();
+ state.handlerInfos = targetHandlerInfos.slice(0, index + 1);
+ recogHandlers = recogHandlers.slice(0, index + 1);
- App.IndexController = Ember.Controller.extend({
- isLoggedIn: Ember.computed.alias('session.isAuthenticated')
+ var intent = new NamedTransitionIntent({
+ name: targetHandler,
+ contexts: contexts
});
- ```
- Injections can also be performed on specific factories.
+ var newState = intent.applyToHandlers(state, recogHandlers, this.getHandler, targetHandler, true, true);
- ```javascript
- App.inject(<full_name or type>, <property name>, <full_name>)
- App.inject('route', 'source', 'source:main')

- ```

- It is important to note that injections can only be performed on
- classes that are instantiated by Ember itself. Instantiating a class
- directly (via `create` or `new`) bypasses the dependency injection
- system.
+ // Get a hash of QPs that will still be active on new route
+ var activeQPsOnNewHandler = {};
+ merge(activeQPsOnNewHandler, queryParams);
- Ember-Data instantiates its models in a unique manner, and consequently
- injections onto models (or all models) will not work as expected. Injections
- on models can be enabled by setting `Ember.MODEL_FACTORY_INJECTIONS`
- to `true`.

+ 1. Triggers the `*model` callbacks on the

+ 2. Triggers the `enter` callback on the same
+ 3. Triggers the `setup` callback on the same
+ 2. A direct transition to `newPost`
+ 1. Triggers the `exit` callback on `showPost`
+ 2. Triggers the `enter` callback on `newPost`
+ 3. Triggers the `setup` callback on `newPost`
+ 3. A direct transition to `about` with a specified
+ context object
+ 1. Triggers the `exit` callback on `newPost`

+ 2. Triggers the `serialize` callback on `about`
+ 3. Triggers the `enter` callback on `about`

- /**
- The DefaultResolver defines the default lookup rules to resolve
- container lookups before consulting the container for registered
- items:
+ function notifyExistingHandlers(router, newState, newTransition) {
+ var oldHandlers = router.state.handlerInfos,
+ changing = [],
+ leavingIndex = null,
+ leaving, leavingChecker, i, oldHandlerLen, oldHandler, newHandler;
- * templates are looked up on `Ember.TEMPLATES`
- * other names are looked up on the application after converting
- the name. For example, `controller:post` looks up
- `App.PostController` by default.
- * there are some nuances (see examples below)
+ oldHandlerLen = oldHandlers.length;
+ for (i = 0; i < oldHandlerLen; i++) {
+ oldHandler = oldHandlers[i];
+ newHandler = newState.handlerInfos[i];
- ### How Resolving Works
+ if (!newHandler || oldHandler.name !== newHandler.name) {
+ leavingIndex = i;
+ break;
+ }
- The container calls this object's `resolve` method with the
- `fullName` argument.
+ if (!newHandler.isResolved) {
+ changing.push(oldHandler);
+ }
+ }
- It first parses the fullName into an object using `parseName`.
+ if (leavingIndex !== null) {
+ leaving = oldHandlers.slice(leavingIndex, oldHandlerLen);
+ leavingChecker = function(name) {
+ for (var h = 0, len = leaving.length; h < len; h++) {
+ if (leaving[h].name === name) {
+ return true;
+ }
+ }
+ return false;
+ };
- Then it checks for the presence of a type-specific instance
- method of the form `resolve[Type]` and calls it if it exists.
- For example if it was resolving 'template:post', it would call
- the `resolveTemplate` method.
+ router._triggerWillLeave(leaving, newTransition, leavingChecker);
+ }
- Its last resort is to call the `resolveOther` method.
+ if (changing.length > 0) {
+ router._triggerWillChangeContext(changing, newTransition);
+ }
- The methods of this object are designed to be easy to override
- in a subclass. For example, you could enhance how a template
- is resolved like so:
+ trigger(router, oldHandlers, true, ['willTransition', newTransition]);
+ }
- ```javascript
- App = Ember.Application.create({
- Resolver: Ember.DefaultResolver.extend({
- resolveTemplate: function(parsedName) {
- var resolvedTemplate = this._super(parsedName);
- if (resolvedTemplate) { return resolvedTemplate; }
- return Ember.TEMPLATES['not_found'];
- }
- })
- });
- ```

+ });
+enifed("router/transition-intent",
+ ["./utils","exports"],

+ "use strict";

- This class implements the methods defined by Ember.Test.Adapter for the
- QUnit testing framework.
+ `RSVP.allSettled` is similar to `RSVP.all`, but instead of implementing
+ a fail-fast method, it waits until all the promises have returned and
+ shows you all the results. This is useful if you want to handle multiple
+ promises' failure states together as a set.
- @class QUnitAdapter
- @namespace Ember.Test
- @extends Ember.Test.Adapter
+ Returns a promise that is fulfilled when all the given promises have been
+ settled. The return promise is fulfilled with an array of the states of
+ the promises passed into the `promises` array argument.
+
+ Each state object will either indicate fulfillment or rejection, and
+ provide the corresponding value or reason. The states will take one of
+ the following formats:
+
+ ```javascript
+ { state: 'fulfilled', value: value }
+ or
+ { state: 'rejected', reason: reason }
+ ```
+
+ Example:
+
+ ```javascript
+ var promise1 = RSVP.Promise.resolve(1);
+ var promise2 = RSVP.Promise.reject(new Error('2'));
+ var promise3 = RSVP.Promise.reject(new Error('3'));
+ var promises = [ promise1, promise2, promise3 ];
+
+ RSVP.allSettled(promises).then(function(array){
+ // array == [
+ // { state: 'fulfilled', value: 1 },
+ // { state: 'rejected', reason: Error },
+ // { state: 'rejected', reason: Error }
+ // ]
+ // Note that for the second item, reason.message will be '2', and for the
+ // third item, reason.message will be '3'.
+ }, function(error) {
+ // Not run. (This block would only be called if allSettled had failed,
+ // for instance if passed an incorrect argument type.)
+ });
+ ```
+
+ @method allSettled
+ @static
+ @for RSVP
+ @param {Array} promises
+ @param {String} label - optional string that describes the promise.

+ `RSVP.denodeify` takes a 'node-style' function and returns a function that
+ will return an `RSVP.Promise`. You can use `denodeify` in Node.js or the
+ browser when you'd prefer to use promises over using callbacks. For example,
+ `denodeify` transforms the following:
- this.resolver = parent && parent.resolver || function() {};
+ ```javascript
+ var fs = require('fs');
- this.registry = new InheritingDict(parent && parent.registry);
- this.cache = new InheritingDict(parent && parent.cache);
- this.factoryCache = new InheritingDict(parent && parent.factoryCache);
- this.resolveCache = new InheritingDict(parent && parent.resolveCache);
- this.typeInjections = new InheritingDict(parent && parent.typeInjections);
- this.injections = {};
+ fs.readFile('myfile.txt', function(err, data){
+ if (err) return handleError(err);
+ handleData(data);
+ });
+ ```
- this.factoryTypeInjections = new InheritingDict(parent && parent.factoryTypeInjections);
- this.factoryInjections = {};
+ into:
- this._options = new InheritingDict(parent && parent._options);
- this._typeOptions = new InheritingDict(parent && parent._typeOptions);
- }
+ ```javascript
+ var fs = require('fs');
+ var readFile = RSVP.denodeify(fs.readFile);
- Container.prototype = {
+ readFile('myfile.txt').then(handleData, handleError);
+ ```
- /**
- @property parent
- @type Container
- @default null
- */
- parent: null,
+ If the node function has multiple success parameters, then `denodeify`
+ just returns the first one:
- /**
- @property children
- @type Array
- @default []
- */
- children: null,
+ ```javascript
+ var request = RSVP.denodeify(require('request'));
- /**
- @property resolver
- @type function
- */
- resolver: null,
+ request('http://example.com').then(function(res) {
+ // ...
+ });
+ ```
- /**
- @property registry
- @type InheritingDict
- */
- registry: null,
+ However, if you need all success parameters, setting `denodeify`'s
+ second parameter to `true` causes it to return all success parameters
+ as an array:
- /**
- @property cache
- @type InheritingDict
- */
- cache: null,
+ ```javascript
+ var request = RSVP.denodeify(require('request'), true);
- /**
- @property typeInjections
- @type InheritingDict
- */
- typeInjections: null,
+ request('http://example.com').then(function(result) {
+ // result[0] -> res
+ // result[1] -> body
+ });
+ ```
- /**
- @property injections
- @type Object
- @default {}
- */
- injections: null,
+ Or if you pass it an array with names it returns the parameters as a hash:
- /**
- @private
+ ```javascript
+ var request = RSVP.denodeify(require('request'), ['res', 'body']);
- @property _options
- @type InheritingDict
- @default null
- */
- _options: null,
+ request('http://example.com').then(function(result) {
+ // result.res
+ // result.body
+ });
+ ```
- /**
- @private
+ Sometimes you need to retain the `this`:
- @property _typeOptions
- @type InheritingDict
- */
- _typeOptions: null,
+ ```javascript
+ var app = require('express')();
+ var render = RSVP.denodeify(app.render.bind(app));
+ ```
- /**
- Returns a new child of the current container. These children are configured
- to correctly inherit from the current container.
+ The denodified function inherits from the original function. It works in all
+ environments, except IE 10 and below. Consequently all properties of the original
+ function are available to you. However, any properties you change on the
+ denodeified function won't be changed on the original function. Example:
- @method child
- @return {Container}
- */
- child: function() {
- var container = new Container(this);
- this.children.push(container);
- return container;
- },

+ cookieJar = request.jar(); // <- Inheritance is used here
- /**
- Sets a key-value pair on the current container. If a parent container,
- has the same key, once set on a child, the parent and child will diverge
- as expected.
+ request('http://example.com', {jar: cookieJar}).then(function(res) {
+ // cookieJar.cookies holds now the cookies returned by example.com
+ });
+ ```
- @method set
- @param {Object} object
- @param {String} key
- @param {any} value
- */
- set: function(object, key, value) {
- object[key] = value;
- },
+ Using `denodeify` makes it easier to compose asynchronous operations instead
+ of using callbacks. For example, instead of:
- /**
- Registers a factory for later injection.
+ ```javascript
+ var fs = require('fs');
- Example:
+ fs.readFile('myfile.txt', function(err, data){

- ```javascript

- /**
- A hook that can be used to describe how the resolver will

+ - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
+ - `thenable` is an object or function that defines a `then` method.
+ - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
+ - `exception` is a value that is thrown using the throw statement.
+ - `reason` is a value that indicates why a promise was rejected.
+ - `settled` the final resting state of a promise, fulfilled or rejected.
- For example, the default Ember `.describe` returns the full
- class name (including namespace) where Ember's resolver expects
- to find the `fullName`.
+ A promise can be in one of three states: pending, fulfilled, or rejected.
- @method describe

+ Promises that are fulfilled have a fulfillment value and are in the fulfilled
+ state. Promises that are rejected have a rejection reason and are in the
+ rejected state. A fulfillment value is never a thenable.
- /**
- A hook to enable custom fullName normalization behaviour
+ Promises can also be said to *resolve* a value. If this value is also a
+ promise, then the original promise's settled state will match the value's
+ settled state. So a promise that *resolves* a promise that rejects will
+ itself reject, and a promise that *resolves* a promise that fulfills will
+ itself fulfill.

- If singletons are not wanted an optional flag can be provided at lookup.
