// If you're using an off-the-shelf adapter:

DS.RESTAdapter.map('Links.List', {
  urls: { embedded: 'load' }
});

// Otherwise:

App.MyAdapter = DS.RESTAdapter.extend({
  // ...  
});

App.Store = DS.Store.extend({
  revision: 11, // or latest revision
  adapter: 'App.MyAdapter'
});

App.MyAdapter.map('Links.List', {
  urls: { embedded: 'load' }
});

Note that you should use:

• embedded: 'load' if you are loading the data embedded in the parent, but the child records have their own ID and you want to save them separately
• embedded: 'always' if you are loading the data embedded in the parent, and you also need to save them embedded in the parent. If the child records have no id, this is the only embedded option that can work.
