Error when cancelling an edit on friend

[DrSayre]

I keep getting an error on page 79. This is how I have my friends edit route:

import Ember from 'ember';

export default Ember.Route.extend({
    resetController(controller, isExiting) {
    if (isExiting) {
      var model = this.get('model');
      model.rollback();
    }
  }
});

When I try to cancel an edit on a friend, I get this error:

Error while processing route: friends.show.index (2)
"model.rollback is not a function. (In 'model.rollback()', 'model.rollback' is undefined)"

Has anybody else had this problem?

Just ran into this as well. There are actually two issues here. One in your code, one in the book. In your code, you have:
var model = this.get('model');
That should be
var model = controller.get('model');

The other issue is that either ember-data's api has changed slightly or the book just has the wrong method name. Rather than
model.rollback()
It should be
model.rollbackAtributes();

Hopefully you've already figured that out since you asked this a few months ago, but figured I'd post for any others that run into this problem.

Hey Brendon, when did you download the book?

This should be fixed in the current version and the repo is now
