Rails - Oct 2005 - Partials and controllers

Newbie question:

From a _form.rhtml file I have:
<%= render(:partial => ''item'', :collection => @items)
%>

In _item.rhtml I have:
<% @tullt = h(item.body) %>
<%= @itemdb = Group.find(:all,
                         :conditions => "id =
''#{@tullt}''").map {|u| [u.name] }
%>
 <%=     @tullt %

I think it would be better to put this code in a controller for this
partial. I made the following item_controller.rb file for this:

class ItemController < ApplicationController
  def index
    @tullt = h(item.body) 
    @itemdb = Group.find(:all,
                       :conditions => "id =
''#{@tullt}''").map {|u|
		       [u.name] }
  end
end

But this doesn''t work (I guess for som obvious reason, I just
haven''t
the knowledge of).

You use something like this to pass the data reference to the partial...

<%= render(:partial => ''item'', :collection =>
@items), :locals=>{
"item_db" => @item_db } %>

And note you now reference item_db (a local) rather then @item_db.
