How to undo changes to a model?

Question

Is it possible to revert the model to a clean state? I mean undo all the changes to its properties and mark the state as being clean?

Ember-Data now has an awesome implementation of this. They utilize the transaction class to manage the changes to your objects, which imo is the right place for this. To rollback changes on a model:

Obtain the Model

// if PostController is a ArrayController or ArrayProxy
p = App.PostController.objectAt(0);

Get the object's associated transaction instance and call it's rollback() method.
```
p.get("transaction").rollback();
```

From Ember 2.0 this is the way to go (once you have got your model object 'model'):

model.rollbackAttributes();

See https://guides.emberjs.com/v2.0.0/models/creating-updating-and-deleting-records/

So, right now ember doesn't save original model's properties at all? – Dziamid Apr 03 '12 at 09:31

UPDATE: works with ember version <= 1.13
