Package @ember-data/store
The store service contains all of the data for records loaded from the server. It is also responsible for creating instances of Model
that wrap the individual data for a record, so that they can be bound to in your Handlebars templates.
By default, applications will have a single Store
service that is automatically created.
The store can be customized by extending the service in the following manner:
app/services/store.js
import Store from '@ember-data/store'; export default class MyStore extends Store {}
You can retrieve models from the store in several ways. To retrieve a record for a specific id, use the Store
's findRecord()
method:
store.findRecord('person', 123).then(function (person) { });
By default, the store will talk to your backend using a standard REST mechanism. You can customize how the store talks to your backend by specifying a custom adapter:
app/adapters/application.js
import DS from 'ember-data'; export default Adapter.extend({ });
You can learn more about writing a custom adapter by reading the Adapter
documentation.
Store createRecord() vs. push() vs. pushPayload()
The store provides multiple ways to create new record objects. They have some subtle differences in their use which are detailed below:
createRecord is used for creating new records on the client side. This will return a new record in the created.uncommitted
state. In order to persist this record to the backend, you will need to call record.save()
.
push is used to notify Ember Data's store of new or updated records that exist in the backend. This will return a record in the loaded.saved
state. The primary use-case for store#push
is to notify Ember Data about record updates (full or partial) that happen outside of the normal adapter methods (for example SSE or Web Sockets).
pushPayload is a convenience wrapper for store#push
that will deserialize payloads if the Serializer implements a pushPayload
method.
Note: When creating a new record using any of the above methods Ember Data will update RecordArray
s such as those returned by store#peekAll()
or store#findAll()
. This means any data bindings or computed properties that depend on the RecordArray will automatically be synced to include the new or updated record values.
