    <p>I'm building an application in which i need to add rows to tables from multiple other models.</p> <p>This is what i have so far (sorry for the sloppy code, first project with ruby/rails). I do realize that I am still missing some key elements to the code for this to function properly, I would just like to make sure I am going about this the right way first. I will also be moving the form to a partial once i get everything working correctly.</p> <pre><code># app/views/ticketbuilder/show.html.erb &lt;ul&gt; &lt;% @event.sections.each do |s| %&gt; &lt;li&gt;&lt;%= s.name %&gt;&lt;/li&gt; &lt;ul&gt; &lt;% s.locations.each do |l| %&gt; &lt;li&gt;&lt;%= l.name %&gt;&lt;/li&gt; &lt;% end %&gt; &lt;/ul&gt; &lt;% end %&gt; &lt;li&gt; &lt;%= form_for([:event, :ticketbuilder], :url =&gt; event_ticketbuilder_url) do |s| %&gt; &lt;%= s.text_field(:section) %&gt; &lt;%= submit_tag("Add Section") %&gt; &lt;%= s.hidden_field(:event_id, @event.id) %&gt; &lt;% end %&gt; &lt;/li&gt; &lt;/ul&gt; # routes.rb resources :event do resources :ticketbuilder end # ticketbuilder_controller.rb class TicketbuilderController &lt; ApplicationController def show @event = Event.find(params[:event_id]) end def new @section = Section.new respond_to do |format| format.html # new.html.erb format.xml { render :xml =&gt; @event } end end end # error message undefined method `model_name' for Symbol:Class </code></pre> <p>The problem I am having is sending the form to the ticketbuilder controller. What I'm trying to accomplish is to have a list of seating sections with child elements for locations. I would like to be able to add new sections and locations directly on the list page.</p> <p>Any suggestions would be greatly appreciated.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
