While testing in the wild I spotted a few problems with it:
* it didn't work for camel case names.
* it was sometimes setting loaded data too late - it needed to use find
and then save data on the record. Instead it should save data in
special array saved on store, indexed by clientId
* there is already method to get attributes in ember-data, it just
doesn't work with Travis.Foo.get('attributes'), it needs
Ember.get(Travis.Foo, 'attributes') - it makes implementation much
shorter
