如何处理ember-data事务错误？

Question

How do I know when a transaction commit fails?

var obj = App.store.findAll(App.Todo).get('firstObject');
var t = App.store.transaction();

t.add(obj);
obj.set('summary','New Summary');
t.commit();
// 403 or 401 is returned from the server (request failed)
a.get('isLoading'); // true
a.get('isError'); // false

Use case: I want a user to see that his action (save object) failed.

Indeed, as of today, ember-data's RESTAdapter does not process errors on commit requests.
