Class DS.HasManyReference
Defined in: | addon/-private/system/references/has-many.js:11 |
---|---|
Module: | ember-data |
ids Array
Module: | ember-data |
---|
Defined in addon/-private/system/references/has-many.js:117
- returns
- Array
- The ids in this has-many relationship
ids()
returns an array of the record ids in this relationship.
Example
app/models/post.js
export default DS.Model.extend({ comments: DS.hasMany({ async: true }) });
let post = store.push({ data: { type: 'post', id: 1, relationships: { comments: { data: [{ type: 'comment', id: 1 }] } } } }); let commentsRef = post.hasMany('comments'); commentsRef.ids(); // ['1']
link String
Module: | ember-data |
---|
Defined in addon/-private/system/references/has-many.js:78
- returns
- String
- The link Ember Data will use to fetch or reload this has-many relationship.
The link Ember Data will use to fetch or reload this has-many relationship.
Example
app/models/post.js
export default DS.Model.extend({ comments: DS.hasMany({ async: true }) });
let post = store.push({ data: { type: 'post', id: 1, relationships: { comments: { links: { related: '/posts/1/comments' } } } } }); let commentsRef = post.hasMany('comments'); commentsRef.link(); // '/posts/1/comments'
load Promise
Module: | ember-data |
---|
Defined in addon/-private/system/references/has-many.js:359
- returns
- Promise
- a promise that resolves with the ManyArray in this has-many relationship.
Loads the relationship if it is not already loaded. If the relationship is already loaded this method does not trigger a new load.
Example
app/models/post.js
export default DS.Model.extend({ comments: DS.hasMany({ async: true }) });
let post = store.push({ data: { type: 'post', id: 1, relationships: { comments: { data: [{ type: 'comment', id: 1 }] } } } }); let commentsRef = post.hasMany('comments'); commentsRef.load().then(function(comments) { //... });
meta Object
Module: | ember-data |
---|
Defined in addon/-private/system/references/has-many.js:157
- returns
- Object
- The meta information for the has-many relationship.
The meta data for the has-many relationship.
Example
app/models/post.js
export default DS.Model.extend({ comments: DS.hasMany({ async: true }) });
let post = store.push({ data: { type: 'post', id: 1, relationships: { comments: { links: { related: { href: '/posts/1/comments', meta: { count: 10 } } } } } } }); let commentsRef = post.hasMany('comments'); commentsRef.meta(); // { count: 10 }
push (objectOrPromise) DS.ManyArray
Module: | ember-data |
---|
Defined in addon/-private/system/references/has-many.js:200
- objectOrPromise
- Array|Promise
- a promise that resolves to a JSONAPI document object describing the new value of this relationship.
- returns
- DS.ManyArray
push
can be used to update the data in the relationship and Ember Data will treat the new data as the canonical value of this relationship on the backend.
Example
app/models/post.js
export default DS.Model.extend({ comments: DS.hasMany({ async: true }) });
let post = store.push({ data: { type: 'post', id: 1, relationships: { comments: { data: [{ type: 'comment', id: 1 }] } } } }); let commentsRef = post.hasMany('comments'); commentsRef.ids(); // ['1'] commentsRef.push([ [{ type: 'comment', id: 2 }], [{ type: 'comment', id: 3 }], ]) commentsRef.ids(); // ['2', '3']
reload Promise
Module: | ember-data |
---|
Defined in addon/-private/system/references/has-many.js:404
- returns
- Promise
- a promise that resolves with the ManyArray in this has-many relationship.
Reloads this has-many relationship.
Example
app/models/post.js
export default DS.Model.extend({ comments: DS.hasMany({ async: true }) });
let post = store.push({ data: { type: 'post', id: 1, relationships: { comments: { data: [{ type: 'comment', id: 1 }] } } } }); let commentsRef = post.hasMany('comments'); commentsRef.reload().then(function(comments) { //... });
remoteType String
Module: | ember-data |
---|
Defined in addon/-private/system/references/has-many.js:31
- returns
- String
- The name of the remote type. This should either be "link" or "ids"
This returns a string that represents how the reference will be looked up when it is loaded. If the relationship has a link it will use the "link" otherwise it defaults to "id".
Example
app/models/post.js
export default DS.Model.extend({ comments: DS.hasMany({ async: true }) });
let post = store.push({ data: { type: 'post', id: 1, relationships: { comments: { data: [{ type: 'comment', id: 1 }] } } } }); let commentsRef = post.hasMany('comments'); // get the identifier of the reference if (commentsRef.remoteType() === "ids") { let ids = commentsRef.ids(); } else if (commentsRef.remoteType() === "link") { let link = commentsRef.link(); }
value DS.ManyArray
Module: | ember-data |
---|
Defined in addon/-private/system/references/has-many.js:313
- returns
- DS.ManyArray
value()
synchronously returns the current value of the has-many relationship. Unlike record.get('relationshipName')
, calling value()
on a reference does not trigger a fetch if the async relationship is not yet loaded. If the relationship is not loaded it will always return null
.
Example
app/models/post.js
export default DS.Model.extend({ comments: DS.hasMany({ async: true }) });
let post = store.push({ data: { type: 'post', id: 1, relationships: { comments: { data: [{ type: 'comment', id: 1 }] } } } }); let commentsRef = post.hasMany('comments'); post.get('comments').then(function(comments) { commentsRef.value() === comments })
