Rails - May 2006 - Redirect whole page from AJAX action that updates a div

Hi,

I am calling an action via AJAX to update a div. The action needs to 
redirect the page in under certain circumstances. However, if I just use 
"redirect_to" in the action then of course what happens is that the
page
I want to redirect to replaces only the div, not the entire page, and I 
get messy nested layouts.

Is there a way around this? Can I redirect the entire document from an 
action that is called via AJAX to update a div?

Thanks for any help!

I''m assuming you''re using link_to_remote in which case you
need to pass
into that method a callback javascript function.  Take a look at 
http://api.rubyonrails.org/classes/ActionView/Helpers/PrototypeHelper.html#M000412.
You probably need to do something like the following:

link_to_remote ''My Link,
    :url => { :action => "action" },
    404 => "alert(''Not found...? Wrong
URL...?'')",
    :failure => "window.location = request"

then when a redirect (302) is sent the failure handler will be hit.  You 
probably want more error and bounds checking though.

I''m pretty sure this is clost to right and would write more but I need 
to run.

You can also conditionally render an .rhtml file that contains a script 
block something like:

<script>
  document.location.href = "...";
</script>

PrototypeHelper will by default try to evaluate scripts in returned 
blocks.
