[tlug] [ruby on rails]: sending back HTTP status codes with XHR

[Mattia Dongili <malattia@example.com>]

Hi,

so it looks like I'm in the process of learning some RoR.
And obviously I'm facing problems from time to time, one of which is:

using the link_to_remote helper there's that nice feature that allows
you to update different DOM objects depending on the outcome of the
server response, so 

  link_to_remote h(truncate(message_item.subject, 60)),
       :url => { :action => "read_message", :uid => message_item.uid .... },
       :update => { :success => "content", :failure => "error" },
       :loading => 'loading_show()',
       :loaded => 'loading_hide()'

Nice, but how the hell I'm supposed to send back an HTTP 500?
I tried overriding the rescue_action in the controller (which I supposed
would automagically return 5xx codes) to no avail.

Hints?
