Rendering of partials from the controller makes it possible to use the same partial template in both the full-page rendering (by calling it from within the template) and when sub-page updates happen (from the controller action responding to Ajax calls). By default, the current layout is not used. # Renders a collection of the same partial by making each element of @wins available through # the local variable "win" as it builds the complete response render :partial => "win", :collection => @wins E.g From my app: list.rhtml <% if !@contacts.empty? %> <%= render :partial => ''contacts'', :collection => @contacts, :locals => { :hidden => false } %> <% end %> _contacts.html <%= contact.name %> Hope this helps /Joseph -- Posted via http://www.ruby-forum.com/.
I believe that when you send a variable to a partial with the :object
argument, it takes on the name of the partial.
In your example, that would mean the variable would be called
"list_form".
If all else fails, you can use the :locals argument, like so:
render(:partial => "list_form", :locals => { :employee =>
employee })

I have ran into another issue. I am using link_to_remote to update a form via ajax. However I need it to replace the div with a partial. However when pressed it jumps me to a blank screen? no error or anything. -- Posted via http://www.ruby-forum.com/.
