Hello I''ve a "User" model. A user, belongs to a state model. I''ve the following in the user form: [code] <%= f.select(:state_id, State.find(:all).map {|c| [c.name, c.id]},{:prompt => "Select a canton"}, {:onchange => "#{remote_function(:url => {:action => "update_municipals"}, :with => "''name=''+value")}"}) %> [/code] However when I add a user, it''s "state_id" is null, but if rename state_id to "state", the id number of the state is saved correctly.
