#user_with_name ⇒ Object

Overrides the user method created by the polymorphic belongs_to user association. If the association is absent, defaults to the user_name string column. This allows VestalVersions::Version#user to either return an ActiveRecord::Base object or a string, depending on what is sent to the user_with_name= method.
