Class RecordReference

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'

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'

The link Ember Data will use to fetch or reload this belongs-to relationship. By default it uses only the "related" resource linkage.

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();
 }

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(...)

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 }

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;
 });

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(...)

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'

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
