HowTo create a DS.Model from ember-data, handling server-side validation errors
# If we save a record using ember-data's RESTadapter, and it fails, Rails
# returns the validation errors of the model as JSON hash:
#
# {"errors":{"name":["may not be blank"]}}
#
# This patches the RESTadapter to add these errors to the invalid record. It
# can be removed when the following Pull Request was merged into ember-data:
# https://github.com/emberjs/data/pull/376
DS.RESTAdapter.reopen
