Defined in:
lib/accepts_nested_ids.rb,
lib/accepts_nested_ids/version.rb,
lib/accepts_nested_ids/nested_id_association.rb

Overview

Allows a model to accept nested association IDs as an attribute. Normally these associations would be immediately saved, even if the parent model transaction failed. This class defers saving to after_save, and also provides dirty attribute tracking on the parent model.
