However, new records that have a dependency on other new - records need to wait for their parent record to be saved and assigned an - ID. In that case, the child record will continue to live in the - transaction until its parent is saved, at which time the transaction will - attempt to commit again. - - For this reason, you should not re-use transactions once you have committed - them.

For instance, if a record is newly created and has - not yet been sent to the adapter to be saved, it would be in the - `created.uncommitted` state. If a record has had local modifications - made to it that are in the process of being saved, the record would be - in the `updated.inFlight` state. (These state paths will be explained - in more detail below.) - - Events are sent by the record or its store to the record's state manager. - How the state manager reacts to these events is dependent on which state - it is in. In some states, certain events will be invalid and will cause - an exception to be raised. - - States are hierarchical. For example, a record can be in the - `deleted.start` state, then transition into the `deleted.inFlight` state. - If a child state does not implement an event handler, the state manager - will attempt to invoke the event on all parent states until the root state is - reached. The state hierarchy of a record is described in terms of a path - string. You can determine a record's current state by getting its manager's - current state path: - - record.get('stateManager.currentPath'); - //=> "created.uncommitted" - - The `DS.Model` states are themselves stateless. What we mean is that, - though each instance of a record also has a unique instance of a - `DS.StateManager`, 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 state - manager points to this global, immutable shared instance. How does a - state know which record it should be acting on? We pass a reference to - the current state manager as the first parameter to every method invoked - on a state. - - The state manager 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. If you need access to the record being acted on, you can - retrieve the state manager's `record` property. For example, if you had - an event handler `myEvent`: - - myEvent: function(manager) { - var record = manager.get('record'); - record.doSomething(); - } - - For more information about state managers in general, see the Ember.js - documentation on `Ember.StateManager`. - - ### Events, Flags, and Transitions - - A state may implement zero or more events, flags, or transitions. - - #### Events - - Events are named functions that are invoked when sent to a record. The - state manager 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: - - aState: DS.State.create({ - myEvent: function(manager, param) { - console.log("Received myEvent with "+param); - } - }) - - To trigger this event: - - 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 state manager'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 - * start <-- currentState - * inFlight - * updated - * inFlight - - If we are currently in the `start` 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: - - var statePath = record.get('stateManager.currentPath'); - if (statePath === 'created.inFlight') { - doSomething(); - } - - You can say: - - 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. - - #### Transitions - - Transitions are like event handlers but are called automatically upon - entering or exiting a state.

While most - applications will use `DS.JSONSerializer`, which reads and writes JSON, the - serializer architecture allows your adapter to transmit things like XML, - strings, or custom binary data. - - Typically, your application's `DS.Adapter` is responsible for both creating a - serializer as well as calling the appropriate methods when it needs to - materialize data or serialize a record. - - The serializer API is designed as a series of layered hooks that you can - override to customize any of the individual steps of serialization and - deserialization. - - The hooks are organized by the three responsibilities of the serializer: - - 1. Determining naming conventions - 2. Serializing records into a serialized form - 3. Deserializing records from a serialized form - - Because Ember Data lazily materializes records, the deserialization - step, and therefore the hooks you implement, are split into two phases: - - 1. Extraction, where the serialized forms for multiple records are - extracted from a single payload. The IDs of each record are also - extracted for indexing. - 2. Materialization, where a newly-created record has its attributes - and relationships initialized based on the serialized form loaded - by the adapter. - - Additionally, a serializer can convert values from their JavaScript - versions into their serialized versions via a declarative API. - - ## Naming Conventions - - One of the most common uses of the serializer is to map attribute names - from the serialized form to your `DS.Model`. For example, in your model, - you may have an attribute called `firstName`: - - ```javascript - App.Person = DS.Model.extend({ - firstName: DS.attr('string') - }); - ``` - - However, because the web API your adapter is communicating with is - legacy, it calls this attribute `FIRST_NAME`. - - You can determine the attribute name used in the serialized form - by implementing `keyForAttributeName`: - - ```javascript - keyForAttributeName: function(type, name) { - return name.underscore.toUpperCase(); - } - ``` - - If your attribute names are not predictable, you can re-map them - one-by-one using the adapter's `map` API: - - ```javascript - App.Adapter.map('App.Person', { - firstName: { key: '*API_USER_FIRST_NAME*' } - }); - ``` - - This API will also work for relationships and primary keys. For - example: - - ```javascript - App.Adapter.map('App.Person', { - primaryKey: '_id' - }); - ``` - - ## Serialization - - During the serialization process, a record or records are converted - from Ember.js objects into their serialized form. - - These methods are designed in layers, like a delicious 7-layer - cake (but with fewer layers). - - The main entry point for serialization is the `serialize` - method, which takes the record and options. - - The `serialize` method is responsible for: - - * turning the record's attributes (`DS.attr`) into - attributes on the JSON object. - * optionally adding the record's ID onto the hash - * adding relationships (`DS.hasMany` and `DS.belongsTo`) - to the JSON object. - - Depending on the backend, the serializer can choose - whether to include the `hasMany` or `belongsTo` - relationships on the JSON hash. - - For very custom serialization, you can implement your - own `serialize` method. In general, however, you will want - to override the hooks described below. - - ### Adding the ID - - The default `serialize` will optionally call your serializer's - `addId` method with the JSON hash it is creating, the - record's type, and the record's ID. The `serialize` method - will not call `addId` if the record's ID is undefined. - - Your adapter must specifically request ID inclusion by - passing `{ includeId: true }` as an option to `serialize`. - - NOTE: You may not want to include the ID when updating an - existing record, because your server will likely disallow - changing an ID after it is created, and the PUT request - itself will include the record's identification. - - By default, `addId` will: - - 1. Get the primary key name for the record by calling - the serializer's `primaryKey` with the record's type. - Unless you override the `primaryKey` method, this - will be `'id'`. - 2. Assign the record's ID to the primary key in the - JSON hash being built. - - If your backend expects a JSON object with the primary - key at the root, you can just override the `primaryKey` - method on your serializer subclass. - - Otherwise, you can override the `addId` method for - more specialized handling. - - ### Adding Attributes - - By default, the serializer's `serialize` method will call - `addAttributes` with the JSON object it is creating - and the record to serialize. - - The `addAttributes` method will then call `addAttribute` - in turn, with the JSON object, the record to serialize, - the attribute's name and its type. - - Finally, the `addAttribute` method will serialize the - attribute: - - 1. It will call `keyForAttributeName` to determine - the key to use in the JSON hash. - 2. It will get the value from the record. - 3. It will call `serializeValue` with the attribute's - value and attribute type to convert it into a - JSON-compatible value. For example, it will convert a - Date into a String. - - If your backend expects a JSON object with attributes as - keys at the root, you can just override the `serializeValue` - and `keyForAttributeName` methods in your serializer - subclass and let the base class do the heavy lifting. - - If you need something more specialized, you can probably - override `addAttribute` and let the default `addAttributes` - handle the nitty gritty. - - ### Adding Relationships - - By default, `serialize` will call your serializer's - `addRelationships` method with the JSON object that is - being built and the record being serialized. The default - implementation of this method is to loop over all of the - relationships defined on your record type and: - - * If the relationship is a `DS.hasMany` relationship, - call `addHasMany` with the JSON object, the record - and a description of the relationship. - * If the relationship is a `DS.belongsTo` relationship, - call `addBelongsTo` with the JSON object, the record - and a description of the relationship. - - The relationship description has the following keys: - - * `type`: the class of the associated information (the - first parameter to `DS.hasMany` or `DS.belongsTo`) - * `kind`: either `hasMany` or `belongsTo` - - The relationship description may get additional - information in the future if more capabilities or - relationship types are added. However, it will - remain backwards-compatible, so the mere existence - of new features should not break existing adapters. -*/ -DS.Serializer = Ember.Object.extend({ - init: function() { - this.mappings = Ember.Map.create(); - this.configurations = Ember.Map.create(); - this.globalConfigurations = {}; - }, - - extract: mustImplement('extract'), - extractMany: mustImplement('extractMany'), - - extractRecordRepresentation: function(loader, type, json, shouldSideload) { - var mapping = this.mappingForType(type); - var embeddedData, prematerialized = {}, reference; - - if (shouldSideload) { - reference = loader.sideload(type, json); - } else { - reference = loader.load(type, json); - } - - this.eachEmbeddedHasMany(type, function(name, relationship) { - var embeddedData = json[this.keyFor(relationship)]; - if (!isNone(embeddedData)) { - this.extractEmbeddedHasMany(loader, relationship, embeddedData, reference, prematerialized); - } - }, this); - - this.eachEmbeddedBelongsTo(type, function(name, relationship) { - var embeddedData = json[this.keyFor(relationship)]; - if (!isNone(embeddedData)) { - this.extractEmbeddedBelongsTo(loader, relationship, embeddedData, reference, prematerialized); - } - }, this); - - loader.prematerialize(reference, prematerialized); - - return reference; - }, - - extractEmbeddedHasMany: function(loader, relationship, array, parent, prematerialized) { - var references = map.call(array, function(item) { - if (!item) { return; } - - var reference = this.extractRecordRepresentation(loader, relationship.type, item, true); - - // If the embedded record should also be saved back when serializing the parent, - // make sure we set its parent since it will not have an ID. - var embeddedType = this.embeddedType(parent.type, relationship.key); - if (embeddedType === 'always') { - reference.parent = parent; - } - - return reference; - }, this); - - prematerialized[relationship.key] = references; - }, - - extractEmbeddedBelongsTo: function(loader, relationship, data, parent, prematerialized) { - var reference = this.extractRecordRepresentation(loader, relationship.type, data, true); - prematerialized[relationship.key] = reference; - - // If the embedded record should also be saved back when serializing the parent, - // make sure we set its parent since it will not have an ID. - var embeddedType = this.embeddedType(parent.type, relationship.key); - if (embeddedType === 'always') { - reference.parent = parent; - } - }, - - //....................... - //.
