DS.Store

DS.Store Class

Extends: Ember.Service

Defined in: addon/-private/system/store.js:140

Module: ember-data

The store contains all of the data for records loaded from the server. It is also responsible for creating instances of DS.Model that wrap the individual data for a record, so that they can be bound to in your Handlebars templates.

Define your application's store like this:

app/services/store.js
import DS from 'ember-data';

export default DS.Store.extend({
});

Most Ember.js applications will only have a single DS.Store that is automatically created by their Ember.Application.

You can retrieve models from the store in several ways. To retrieve a record for a specific id, use DS.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 DS.Adapter.extend({
});

You can learn more about writing a custom adapter by reading the DS.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 DS.RecordArrays such as those returned by store#peekAll(), store#findAll() or store#filter(). 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.
