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!
