ember-rollback-relationships

ember install ember-rollback-relationships

Adds behaviour to DS.Model so belongsTo and hasMany relationships can also be rolled back.

Notes
---

Don't forget to call model.rollbackAttributes() yourself if required.

Calling this._super(); is mandatory if you are using any of the following Events:
- ready
- didCreate
- didLoad
- didUpdate

Many-to-many relationships are not supported!
