Rails - Jul 2005 - Remove an item from a list with ajax

I''ve been following along with rails and ajax and have been getting on
ok, until now.
I have a list of items, each has a link_to_remote call to a destroy action. 
My problem is that when this is called it renders the entire page in
the div that should have been updated. So I took out my call to
redirect_to (:action => "new"), but now it complains that the
template
for the action ''destroy'' does not exist.
I''ve tried render(:layout => false) both with and without the
redirect
and this causes errors or makes no difference.

Could anybody enlighten me to what must be quite simple.

My ajax call:

<%= link_to_remote "Destroy",
      :update => ''list'',
      :complete => "new
Effect.Fade(''#{element.id}'')",
      :url => {:action => "destroy", :id => image.id} %>


My destroy action:

def destroy
	Image.find(params[:id]).destroy
	redirect_to (:action => ''new'')
end

Many Thanks

Kieran

Two things:

1. If you are destroying something, and using Effect.Fade, you don''t
need
the :update param in your call. Just let javascript fade it out.
2. I''m guessing that your app is getting upset because you are trying
to
return an entire page.

try this:

def destroy
Image.find(params[:id]).destroy
end
