Class RecordReference
Extends: | Reference |
---|---|
Defined in: | ../store/addon/-private/system/references/record.ts:13 |
Module: | @ember-data/store |
id String
Module: | @ember-data/store |
---|
Defined in ../store/addon/-private/system/references/record.ts:34
- returns
- String
- The id of the record.
The id
of the record that this reference refers to.
Together, the type
and id
properties form a composite key for the identity map.
Example
let userRef = store.getReference('user', 1); userRef.id(); // '1'
identifier String
Module: | @ember-data/store |
---|
Defined in ../store/addon/-private/system/references/record.ts:55
- returns
- String
- The identifier of the record.
The identifier
of the record that this reference refers to.
Together, the type
and id
properties form a composite key for the identity map.
Example
let userRef = store.getReference('user', 1); userRef.identifier(); // '1'
link String
Module: | @ember-data/store |
---|
Inherited from Reference ../store/addon/-private/system/references/reference.ts:109
- returns
- String
- The link Ember Data will use to fetch or reload this belongs-to relationship.
The link Ember Data will use to fetch or reload this belongs-to relationship.
Example
// models/blog.js import Model, { belongsTo } from '@ember-data/model'; export default Model.extend({ user: belongsTo({ async: true }) }); let blog = store.push({ data: { type: 'blog', id: 1, relationships: { user: { links: { related: '/articles/1/author' } } } } }); let userRef = blog.belongsTo('user'); // get the identifier of the reference if (userRef.remoteType() === "link") { let link = userRef.link(); }
load Promise<record>
Module: | @ember-data/store |
---|
Defined in ../store/addon/-private/system/references/record.ts:166
- returns
- Promise<record>
- the record for this RecordReference
Triggers a fetch for the backing entity based on its remoteType
(see remoteType
definitions per reference type).
Example
let userRef = store.getReference('user', 1); // load user (via store.find) userRef.load().then(...)
meta Object
Module: | @ember-data/store |
---|
Inherited from Reference ../store/addon/-private/system/references/reference.ts:165
- returns
- Object
- The meta information for the belongs-to relationship.
The meta data for the belongs-to relationship.
Example
// models/blog.js import Model, { belongsTo } from '@ember-data/model'; export default Model.extend({ user: belongsTo({ async: true }) }); let blog = store.push({ data: { type: 'blog', id: 1, relationships: { user: { links: { related: { href: '/articles/1/author' }, meta: { lastUpdated: 1458014400000 } } } } } }); let userRef = blog.belongsTo('user'); userRef.meta() // { lastUpdated: 1458014400000 }
push (objectOrPromise)
Module: | @ember-data/store |
---|
Defined in ../store/addon/-private/system/references/record.ts:96
- objectOrPromise
- a JSON:API ResourceDocument or a promise resolving to one
- returns
- a promise for the value (record or relationship)
This API allows you to provide a reference with new data. The simplest usage of this API is similar to store.push
: you provide a normalized hash of data and the object represented by the reference will update.
If you pass a promise to push
, Ember Data will not ask the adapter for the data if another attempt to fetch it is made in the interim. When the promise resolves, the underlying object is updated with the new data, and the promise returned by this function is resolved with that object.
For example, recordReference.push(promise)
will be resolved with a record.
Example
let userRef = store.getReference('user', 1); // provide data for reference userRef.push({ data: { id: "1", type: "user", attributes: { username: "@user" } } }).then(function(user) { userRef.value() === user; });
reload Promise<record>
Module: | @ember-data/store |
---|
Defined in ../store/addon/-private/system/references/record.ts:189
- returns
- Promise<record>
- the record for this RecordReference
Reloads the record if it is already loaded. If the record is not loaded it will load the record via store.findRecord
Example
let userRef = store.getReference('user', 1); // or trigger a reload userRef.reload().then(...)
remoteType String
Module: | @ember-data/store |
---|
Defined in ../store/addon/-private/system/references/record.ts:76
- returns
- String
- 'identity'
How the reference will be looked up when it is loaded. Currently this always returns identity
to signify that a record will be loaded by its type
and id
.
Example
const userRef = store.getReference('user', 1); userRef.remoteType(); // 'identity'
value Model
Module: | @ember-data/store |
---|
Defined in ../store/addon/-private/system/references/record.ts:140
- returns
- Model
- the record for this RecordReference
If the entity referred to by the reference is already loaded, it is present as reference.value
. Otherwise the value returned by this function is null
.
Example
let userRef = store.getReference('user', 1); userRef.value(); // user
