DS.Store#peekRecord()

Get a record by a given type and ID without triggering a fetch.

This method will synchronously return the record if it is available in the store, otherwise it will return null. A record is available if it has been fetched earlier, or pushed manually into the store.

Note: This is an synchronous method and does not return a promise.

var post = store.peekRecord('post', 1);

post.get('id'); // 1
