Could somebody point me to some example code? This must be simple, I just can't find any examples. I need a new view (new.rhtml) to include the creation of a child object. I have a table for servers (Servers) and a table for IP Addresses (Ips). Server has_many :ips Ip belongs_to :server In my new.rhtml I want the IP entered to become a record in the Ips table. The Ips table is very simple. It has two rows, id and server_id. Where would I look for example code for new.rhtml and server_controller.rb? Thanks for the help! - Don

Since you need multiple IPs per server, you'll want to work out some way to address that in the view. One way would be with Ajax and/or RJS templates; another would be to let the user enter a comma-separated list of IPs.. yet another would be to ask how many IPs there will be up front, before showing the 'new' template, and build that many form entries via a partial. #server_controller.rb model :server model :ip def new @server = Server.new(params[:server]) @ip = Ip.new(params[:ip]) @server.ips << @ip if request.post? and @server.save flash[:notice] = "All systems Go." redirect_to :action => 'show', :id => @server end end #new.rhtml #I've omitted various useful things like labels, help text, etc. <%= start_form_tag :action => 'new' %> <%= text_field 'server', 'some_property' %> <%= select 'server', 'something_else', some_list_of_options %> <%= text_field 'ip', 'address' %> <%= submit_tag "Create Server" %> <%= end_form_tag %> Every input field value for 'ip' will be available in params[:ip] once this form is posted, and every 'server' input field will be found in params[:server]. Saving the parent object (@server) also saves any unsaved children, so the new Server and Ip objects are both saved in one step.
