EmberJS-Persisting Records

Quiz

Persisting Records

The Ember.js Records data are persisted on a per-instance basis. The DS.Model takes the save() on any instance to make a network request.

store.createRecord('route', {
   //declare properties
   route.save();
});

In the above code, route.save() helps to records the data.
