Set up callback after transaction

Question

I am trying to achieve something that, it seems to me, has a simple answer, but for some reason I cannot find it by reading the source code of ember-data .

I would like to trigger an action after a specific set of changes has been made to the data warehouse. This is my current code:

 var transaction = App.store.transaction(); user = App.get('currentUser'); transaction.add(user); user.set('name', "Michael Jackson"); transaction.commit(); App.navigate('dashboard'); 

My first attempt was to add an observer to this isDirty custom property, but a) it does not look idiomatic and, more importantly, b) I would have to manually remove this observer at the end - which is error prone if some exception occurs between they are not deleted, for example.

Any ideas? How do you do this?

You can use didCreate and didUpdate for the model. I assume you have a user model, so that:

 MyApp.User = DS.Model.extend({ first: DS.attr('string'), page: DS.attr('string'), didUpdate: function() { //Do something }, didCreate: function() { //do something } });
