Class DS.RESTAdapter

coalesceFindRequests

Defined in addon/adapters/rest.js:351

By default the RESTAdapter will send each find request coming from a store.find or from accessing a relationship separately to the server. If your server supports passing ids as a query string, you can set coalesceFindRequests to true to coalesce all find requests within a single runloop.

For example, if you have an initial payload of:

{
  post: {
    id: 1,
    comments: [1, 2]
  }
}

By default calling post.get('comments') will trigger the following requests(assuming the comments haven't been loaded before):

GET /comments/1
GET /comments/2

If you set coalesceFindRequests to true it will instead trigger the following request:

GET /comments?ids[]=1&ids[]=2

Setting coalesceFindRequests to true also works for store.find requests and belongsTo relationships accessed within the same runloop. If you set coalesceFindRequests: true

store.findRecord('comment', 1);
store.findRecord('comment', 2);

will also send a request to: GET /comments?ids[]=1&ids[]=2

Note: Requests coalescing rely on URL building strategy. So if you override buildURL in your app groupRecordsForFindMany more likely should be overridden as well in order for coalescing to work.

defaultSerializer

Inherited from DS.Adapter addon/adapter.js:65

If you would like your adapter to use a custom serializer you can set the defaultSerializer property to be the name of the custom serializer.

Note the defaultSerializer serializer has a lower priority than a model specific serializer (i.e. PostSerializer) or the application serializer.

import DS from 'ember-data';

export default DS.Adapter.extend({
  defaultSerializer: 'django'
});

headers

Defined in addon/adapters/rest.js:435

Some APIs require HTTP headers, e.g. to provide an API key. Arbitrary headers can be set as key/value pairs on the RESTAdapter's headers object and Ember Data will send them along with each ajax request. For dynamic headers see headers customization.

import DS from 'ember-data';

export default DS.RESTAdapter.extend({
  headers: {
    'API_KEY': 'secret key',
    'ANOTHER_HEADER': 'Some header value'
  }
});

host

Defined in addon/adapters/rest.js:418

An adapter can target other hosts by setting the host property.

import DS from 'ember-data';

export default DS.RESTAdapter.extend({
  host: 'https://api.example.com'
});

Requests for the Post model would now target https://api.example.com/post/.

namespace

Defined in addon/adapters/rest.js:400

Endpoint paths can be prefixed with a namespace by setting the namespace property on the adapter:

import DS from 'ember-data';

export default DS.RESTAdapter.extend({
  namespace: 'api/1'
});

Requests for the Post model would now target /api/1/post/.
