+ ``` + + 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") + }); + ``` + + ```handlebars + {{textarea value=writtenWords}} + {{textarea value=twoWayWrittenWords}} + ``` + + ```html + + + <-- both updated in real time --> + + + ``` + + ## Actions + + The helper can send multiple actions based on user events. + + The action property defines the action which is send when + the user presses the return key. + + ```handlebars + {{input action="submit"}} + ``` + + The helper allows some user events to send actions. + + * `enter` + * `insert-newline` + * `escape-press` + * `focus-in` + * `focus-out` + * `key-press` + + For example, if you desire an action to be sent when the input is blurred, + you only need to setup the action name to the event name property. + + ```handlebars + {{textarea focus-in="alertMessage"}} + ``` + + See more about [Text Support Actions](/api/classes/Ember.TextArea.html) + + ## Extension + + Internally, `{{textarea}}` creates an instance of `Ember.TextArea`, passing + arguments from the helper to `Ember.TextArea`'s `create` method.

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: + + ```handlebars + {{#view tagName="span" class="a-custom-class"}} + hello. + {{/view}} + ``` + + Results in the following HTML structure: + + ```html +
+ + hello. + +
+ ``` + + ### Supplying a different view class + + `{{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}} + ``` + + The first argument can also be a relative path accessible from the current + context. + + ```javascript + 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}}') + }); + + MyApp.OuterView.create().appendTo('body'); + ``` + + Will result in the following HTML: + + ```html +
+
+ hi +
+
+ ``` + + ### Blockless use + + 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.

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"): + + ``` + valueBinding: "MyApp.someController.title" + ``` + + 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. + + ## One Way Bindings + + 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: + + ``` + bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles") + ``` + + 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`. + + 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. + + 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). + + ## Adding Bindings Manually + + 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. + + 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. + + 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: + + ```javascript + binding = Ember.Binding.from("valueBinding").to("value"); + ``` + + 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: + + ```javascript + binding.connect(this); + ``` + + 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. + + This also allows you to bind between objects using the paths you declare in + `from` and `to`: + + ```javascript + // Example 1 + binding = Ember.Binding.from("App.someObject.value").to("value"); + binding.connect(this); + + // Example 2 + binding = Ember.Binding.from("parentView.value").to("App.someObject.value"); + binding.connect(this); + ``` + + Now that the binding is connected, it will observe both the from and to side + and relay changes. + + 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): + + ```javascript + Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value"); + ``` + + Both of these code fragments have the same effect as doing the most friendly + form of binding creation like so: + + ```javascript + MyApp.anotherObject = Ember.Object.create({ + valueBinding: "MyApp.someController.value", + + // OTHER CODE FOR THIS OBJECT... + }); + ``` + + Ember's built in binding creation method makes it easy to automatically + create bindings for you.

    + click me +
    + ``` + + And application code + + ```javascript + App.ApplicationController = Ember.Controller.extend({ + actions: { + anActionName: function() { + } + } + }); + ``` + + Will result in the following rendered HTML + + ```html +

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: + + ```handlebars +
    + + +
    + ``` + + To disable bubbling, pass `bubbles=false` to the helper: + + ```handlebars + + ``` + + If you need the default handler to trigger you should either register your + own event handler, or use event methods on your view class. See [Ember.View](/api/classes/Ember.View.html) + 'Responding to Browser Events' for more information. + + ### Specifying DOM event type + + 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: + + ```handlebars +
    + click me +
    + ``` + + See `Ember.View` 'Responding to Browser Events' for a list of + acceptable DOM event names. + + ### Specifying whitelisted modifier keys + + 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 +
    + click me +
    + ``` + + This way the `{{action}}` will fire when clicking with the alt key pressed down. + + Alternatively, supply "any" to the `allowedKeys` option to accept any combination of modifier keys. + + ```handlebars +
    + click me with any key pressed +
    + ``` + + ### Specifying a Target + + There are several possible target objects for `{{action}}` helpers: + + 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. + + 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 }} +
    + click me +
    + ``` + + ```javascript + App.ApplicationView = Ember.View.extend({ + actions: { + anActionName: function(){} + } + }); + + ``` + + ### Additional Parameters + + You may specify additional parameters to the `{{action}}` helper. These + parameters are passed along as the arguments to the JavaScript function + implementing the action. + + ```handlebars + {{#each person in people}} +
    + click me +
    + {{/each}} + ``` + + Clicking "click me" will trigger the `edit` method on the current controller + with the value of `person` as a parameter. + + @method action + @for Ember.Handlebars.helpers + @param {String} actionName + @param {Object} [context]* + @param {Hash} options + */ + function actionHelper(actionName) { + var length = arguments.length;

This can + be overridden for a single use of `{{link-to}}` by supplying + a `tagName` option: + + ```handlebars + {{#link-to 'photoGallery' tagName="li"}} + Great Hamster Photos + {{/link-to}} + ``` + + ```html +
  • + Great Hamster Photos +
    • + ``` + + To override this option for your entire application, see + "Overriding Application-wide Defaults". + + ### Disabling the `link-to` helper + By default `{{link-to}}` is enabled. + any passed value to `disabled` helper property will disable the `link-to` helper. + + static use: the `disabled` option: + + ```handlebars + {{#link-to 'photoGallery' disabled=true}} + Great Hamster Photos + {{/link-to}} + ``` + + dynamic use: the `disabledWhen` option: + + ```handlebars + {{#link-to 'photoGallery' disabledWhen=controller.someProperty}} + Great Hamster Photos + {{/link-to}} + ``` + + 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`. + + ```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; + }) + }); + ``` + + see "Overriding Application-wide Defaults" for more. + + ### 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}}`: + + ```handlebars + {{#link-to 'photoGallery.recent'}} + Great Hamster Photos from the last week + {{/link-to}} + ``` + + will result in + + ```html +     + Great Hamster Photos + + ``` + + The CSS class name used for active classes can be customized + for a single use of `{{link-to}}` by passing an `activeClass` + option: + + ```handlebars + {{#link-to 'photoGallery.recent' activeClass="current-url"}} + Great Hamster Photos from the last week + {{/link-to}} + ``` + + ```html + + Great Hamster Photos + + ``` + + To override this option for your entire application, see + "Overriding Application-wide Defaults". + + ### 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.Router.map(function() { + this.resource("photoGallery", {path: "hamster-photos/:photo_id"}); + }); + ``` + + ```handlebars + {{#link-to 'photoGallery' aPhoto}} + {{aPhoto.title}} + {{/link-to}} + ``` + + ```html + + Tomster + + ``` + + ### 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: + + ```handlebars + {{#link-to 'photoGallery.comment' aPhoto comment}} + {{comment.body}} + {{/link-to}} + ``` + + ```html + + A+++ would snuggle again. + + ``` + + ### 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: + + ```javascript + App.Router.map(function() { + this.resource("photoGallery", {path: "hamster-photos/:photo_id"}); + }); + ``` + + ```handlebars + {{#link-to 'photoGallery' aPhotoId}} + {{aPhoto.title}} + {{/link-to}} + ``` + + ```html + + Tomster + + ``` + + 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: + + ```handlebars + {{#link-to 'photoGallery' aPhotoId preventDefault=false}} + {{aPhotoId.title}} + {{/link-to}} + ``` + + ### 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: + + ```handlebars + {{#link-to aPhoto tagName='li' title='Following this link will change your life' classNames='pic sweet'}} + Uh-mazing! + {{/link-to}} + ``` + + 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`. + + ### Overriding Application-wide Defaults + ``{{link-to}}`` creates an instance of Ember.LinkView + for rendering.

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 + Ember.computed.max = function(dependentKey) { + return Ember.reduceComputed(dependentKey, { + initialValue: -Infinity, + + addedItem: function(accumulatedValue, item, changeMeta, instanceMeta) { + return Math.max(accumulatedValue, item); + }, + + removedItem: function(accumulatedValue, item, changeMeta, instanceMeta) { + if (item < accumulatedValue) { + return accumulatedValue; + } + } + }); + }; + ``` + + 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 + 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.

This allows the observing objects to be notified and + computed properties to be handled properly. + + More documentation about `get` and `set` are below. + + ## Observing Property Changes + + 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: + + ```javascript + Ember.Object.extend({ + valueObserver: function() { + // Executes whenever the "value" property changes + }.observes('value') + }); + ``` + + 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`.

This is useful for those times when you need to + implement a property that is composed of one or more member + properties. + + ### Unknown Properties + + 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.

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. + + All Sets are observable via the Enumerable Observer API - which works + on any enumerable object including both Sets and Arrays. + + ## Creating a Set + + 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. + + 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()`. + + ```javascript + // creates a new empty set + var foundNames = new Ember.Set(); + + // creates a set with four names in it. + var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P + + // creates a copy of the names set. + var namesCopy = new Ember.Set(names); + + // same as above. + var anotherNamesCopy = names.copy(); + ``` + + ## Adding/Removing Objects + + 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. + + 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. + + NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do + so will be ignored. + + 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. + + ## Testing for an Object + + To test for an object's presence in a set you simply call + `Ember.Set#contains()`. + + ## 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.

Views whose HTML element is self closing (e.g. ``) + cannot have a layout and this property will be ignored. + + Most typically in Ember a layout will be a compiled `Ember.Handlebars` + template. + + 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: + + ```javascript + AViewWithLayout = Ember.View.extend({ + layout: Ember.Handlebars.compile("
    {{yield}}
    "), + template: Ember.Handlebars.compile("I got wrapped") + }); + ``` + + Will result in view instances with an HTML representation of: + + ```html +
    +
    + I got wrapped +
    +
    + ``` + + See [Ember.Handlebars.helpers.yield](/api/classes/Ember.Handlebars.helpers.html#method_yield) + for more information. + + ## Responding to Browser Events + + 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. + + ### Method Implementation + + 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. + + ```javascript + AView = Ember.View.extend({ + click: function(event) { + // will be called when when an instance's + // rendered element is clicked + } + }); + ``` + + ### Event Managers + + 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. + + ```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 + } + }) + }); + ``` + + An event defined for an event manager takes precedence over events of the + same name handled through methods on the view. + + ```javascript + AView = Ember.View.extend({ + mouseEnter: function(event) { + // will never trigger. + }, + eventManager: Ember.Object.create({ + mouseEnter: function(event, view) { + // takes precedence over AView#mouseEnter + } + }) + }); + ``` + + 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. + + ```javascript + var App = Ember.Application.create(); + App.OuterView = Ember.View.extend({ + template: Ember.Handlebars.compile("outer {{#view 'inner'}}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.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. + } + }); + ``` + + ### 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` + + Form events: + + * `submit` + * `change` + * `focusIn` + * `focusOut` + * `input` + + HTML5 drag and drop events: + + * `dragStart` + * `drag` + * `dragEnter` + * `dragLeave` + * `dragOver` + * `dragEnd` + * `drop` + + ## Handlebars `{{view}}` Helper + + Other `Ember.View` instances can be included as part of a view's template by + using the `{{view}}` Handlebars helper.

For example, in response to a `GET` request for + `/posts/1`, the JSON should look like this: + + ```js + { + "post": { + "id": 1, + "title": "I'm Running to Reform the W3C's Tag", + "author": "Yehuda Katz" + } + } + ``` + + Similarly, in response to a `GET` request for `/posts`, the JSON should + look like this: + + ```js + { + "posts": [ + { + "id": 1, + "title": "I'm Running to Reform the W3C's Tag", + "author": "Yehuda Katz" + }, + { + "id": 2, + "title": "Rails is omakase", + "author": "D2H" + } + ] + } + ``` + + ### Conventional Names + + Attribute names in your JSON payload should be the camelCased versions of + the attributes in your Ember.js models. + + For example, if you have a `Person` model: + + ```js + App.Person = DS.Model.extend({ + firstName: DS.attr('string'), + lastName: DS.attr('string'), + occupation: DS.attr('string') + }); + ``` + + The JSON returned should look like this: + + ```js + { + "person": { + "id": 5, + "firstName": "Barack", + "lastName": "Obama", + "occupation": "President" + } + } + ``` + + ## Customization + + ### Endpoint path customization + + Endpoint paths can be prefixed with a `namespace` by setting the namespace + property on the adapter: + + ```js + DS.RESTAdapter.reopen({ + namespace: 'api/1' + }); + ``` + Requests for `App.Person` would now target `/api/1/people/1`. + + ### Host customization + + An adapter can target other hosts by setting the `host` property. + + ```js + DS.RESTAdapter.reopen({ + host: 'https://api.example.com' + }); + ``` + + ### Headers customization + + Some APIs require HTTP headers, e.g. to provide an API key.

What that means is + that, the hierarchical states that each of *those* points to is a + shared data structure. For performance reasons, instead of each + record getting its own copy of the hierarchy of states, each record + points to this global, immutable shared instance. How does a state + know which record it should be acting on? We pass the record + instance into the state's event handlers as the first argument. + + The record passed as the first parameter is where you should stash + state about the record if needed; you should never store data on the state + object itself. + + ### Events and Flags + + A state may implement zero or more events and flags. + + #### Events + + Events are named functions that are invoked when sent to a record. The + record will first look for a method with the given name on the + current state. If no method is found, it will search the current + state's parent, and then its grandparent, and so on until reaching + the top of the hierarchy. If the root is reached without an event + handler being found, an exception will be raised. This can be very + helpful when debugging new features. + + Here's an example implementation of a state with a `myEvent` event handler: + + ```javascript + aState: DS.State.create({ + myEvent: function(manager, param) { + console.log("Received myEvent with", param); + } + }) + ``` + + To trigger this event: + + ```javascript + record.send('myEvent', 'foo'); + //=> "Received myEvent with foo" + ``` + + Note that an optional parameter can be sent to a record's `send()` method, + which will be passed as the second parameter to the event handler. + + Events should transition to a different state if appropriate. This can be + done by calling the record's `transitionTo()` method with a path to the + desired state. The state manager will attempt to resolve the state path + relative to the current state. If no state is found at that path, it will + attempt to resolve it relative to the current state's parent, and then its + parent, and so on until the root is reached. For example, imagine a hierarchy + like this: + + * created + * uncommitted <-- currentState + * inFlight + * updated + * inFlight + + If we are currently in the `uncommitted` state, calling + `transitionTo('inFlight')` would transition to the `created.inFlight` state, + while calling `transitionTo('updated.inFlight')` would transition to + the `updated.inFlight` state. + + Remember that *only events* should ever cause a state transition. You should + never call `transitionTo()` from outside a state's event handler. If you are + tempted to do so, create a new event and send that to the state manager. + + #### Flags + + Flags are Boolean values that can be used to introspect a record's current + state in a more user-friendly way than examining its state path. For example, + instead of doing this: + + ```javascript + var statePath = record.get('stateManager.currentPath'); + if (statePath === 'created.inFlight') { + doSomething(); + } + ``` + + You can say: + + ```javascript + if (record.get('isNew') && record.get('isSaving')) { + doSomething(); + } + ``` + + If your state does not set a value for a given flag, the value will + be inherited from its parent (or the first place in the state hierarchy + where it is defined). + + The current set of flags are defined below. If you want to add a new flag, + in addition to the area below, you will also need to declare it in the + `DS.Model` class. + + + * [isEmpty](DS.Model.html#property_isEmpty) + * [isLoading](DS.Model.html#property_isLoading) + * [isLoaded](DS.Model.html#property_isLoaded) + * [isDirty](DS.Model.html#property_isDirty) + * [isSaving](DS.Model.html#property_isSaving) + * [isDeleted](DS.Model.html#property_isDeleted) + * [isNew](DS.Model.html#property_isNew) + * [isValid](DS.Model.html#property_isValid) + + @namespace DS + @class RootState + */ + + function didSetProperty(record, context) { + if (context.value === context.originalValue) { + delete record._attributes[context.name]; + record.send('propertyWasReset', context.name); + } else if (context.value !== context.oldValue) { + record.send('becomeDirty'); + } + + record.updateRecordArraysLater(); + } + + // Implementation notes: + // + // Each state has a boolean value for all of the following flags: + // + // * isLoaded: The record has a populated `data` property.
