Rails - Jul 2011 - Render a "new" form in another view

Hi!

I have a list where you can add items, where Items are nested inside Lists.

So, now I want to render my form partial to create new items in the Lists 
show view. I want to be able to add items to the list without leaving the 
list through a link.

My _form partial looks like this
<%= semantic_form_for [@item.list, @item] do |f| %> 
  <%= f.inputs "Item" do %> 
    <%= f.input :title %> 
    <%= f.input :amount %> 
    <%= f.input :unit %> 
  <% end %> 
   <%= f.buttons %> 
<% end %>

I have tried to just do  <%= render ''items/form'' %>
which doesn''t work. I
guess I have to send populate the @item variable when rendering the 
template.
Also, I''m not sure how the form will know this is a new action and not
an
edit.

It will know because the @item won''t have an ID -- @item.new_record?  
will return true.
