Apologies for such a basic question. I''ve wracked my brain on this a couple days so if anyone takes pity, please help me out. I''ve been looking at STI (Single Table Inheritance) at the Rails Wiki and decided to try it out. I got it working in the model and controllers but can''t figure out how to make a proper view that will take the values and add them into the database. General story: I want a user to be able to classify their friends in a variety of ways and save that as a relationship. Here''s what I have in my model (all code is based on wiki example): def self.factory(type = nil, params = nil) case type when "Family" return Family.new(params) when "Contact" return Contact.new(params) when nil return Friend.new(params) end This is the controller: def new @friend = Friend.factory(params[:friend_type]) end def create @friend = Friend.factory(params[:friend_type], params[:friend]) if @friend.save flash[:notice] = ''Friend was successfully created.'' redirect_to :action => ''list'' else render :action => ''new'' end end I have absolutely no idea how to create a view that will take these values and add them to the database. I tried stuff like: <%= start_form_tag :action => ''create'' %> <%= render :partial => ''form'' %> <%= select (:friend, :create, :friend_type, %w{ Soulmate Family }) %> <%= submit_tag "Create" %> <%= end_form_tag %> The STI wiki says add: <%= hidden_field_tag "person_type", @person[:type] %> but this makes no sense to me. I''ve basically been taking stabs in the dark. It would be nice if someone can point me in the right direction for understanding views as well. Again, my apologies for asking all this basic stuff. Sam
