My approach tends to be: just as you have pairings of new/create,
edit/update , you also need a pairing of delete/destroy.

So: in your routes, you add a :member route:

map.resources :forums, :member => {:delete => :get}

and your delete controller simply renders an "are you sure?" form. That form:

<% form_for :message, :html => { :method => :delete }, :url =>
forum_path(@forum) do |f| -%>
<p class="submit"><%= submit_tag "Delete forum" %></p>
<% end -%>

You still end up calling forums#destroy with a DELETE HTTP method, you
just have an interstitial delete view first.

It always annoys me that rails doesn't generate a "delete" view to
pair with "destroy"; to my mind, this is the only right way to do it.
Once this is in place, making it happen automagically via js is easy.
