Class DS.RecordReference

An RecordReference is a low-level API that allows users and addon author to perform meta-operations on a record.

Show:

Module: ember-data
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

1

3
let userRef = store.getReference('user', 1);

userRef.id(); // '1'
Module: ember-data
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

1
2
3
4
let userRef = store.getReference('user', 1);

// load user (via store.find)
userRef.load().then(...)
Module: ember-data
objectOrPromise
Promise|Object
returns
RSVP.Promise<record> 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.

 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;
 });
Module: ember-data
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

4
let userRef = store.getReference('user', 1);

// or trigger a reload
userRef.reload().then(...)
Module: ember-data
returns
String
'identity'

How the reference will be looked up when it is loaded: Currently this always return identity to signifying that a record will be loaded by the type and id.

Example

1

3
const userRef = store.getReference('user', 1);

userRef.remoteType(); // 'identity'
Module: ember-data
returns
DS.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

1

3
 let userRef = store.getReference('user', 1);

 userRef.value(); // user
