Thanks Frederick, but I still do not understand what's going on here. I changed this line to belongs_to :contact_type .. The result is the same.
Controller was generated as standart scaffold. def create @contact = Contact.new(params[:contact].merge(:user => current_user)) respond_to do |format| if(@contact.save) ... Contact can't be blank Do you know when this validation should appear? > > Your problem may lie here - the type attribute (if present) is used for > single table inheritance. Obviously this is adding a type method rather than > an attribute but I would definitely try changing that association name. > -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
