I'd recommend creating an attr_accessor for :primary on your Title model. In your form you could do something like: f.object.roles.each do |role| f.radio_button :primary, :role.id f.label :primary
which should have the desired behavior. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
