DS.Model#hasDirtyAttributes

If this property is true the record is in the dirty state. The record has local changes that have not yet been saved by the adapter. This includes records that have been created (but not yet saved) or deleted.

Example

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

store.findRecord('model', 1).then(function(model) {
  model.get('hasDirtyAttributes'); // false
  model.set('foo', 'some value');
  model.get('hasDirtyAttributes'); // true
});
