DS.Model#isLoaded

If this property is true the record is in the loaded state. A record enters this state when its data is populated. Most of a record's lifecycle is spent inside substates of the loaded state.

Example

var record = store.createRecord('model');
record.get('isLoaded'); // true

store.findRecord('model', 1).then(function(model) {
  model.get('isLoaded'); // true
});
