Rails - Apr 2006 - checkboxes for filtered search

I have a page that renders a series of about 20 checkboxes on the  
left hand side with content on the right.  These checkboxes are  
created from a DB and that part is all working well.

What I want to do is have a user click on a checkbox [genres] and  
have the content on the right be filtered based on the checkbox  
ticked.  If a user clicks on more than one checkbox than only those  
stories are shown.

So for example the tables are like this :

*Stories*
id
title
genre_id

------------------

*Genre*
id
description

-------------------

*genre_stories*
stories_id
genre_id


How do I achieve this?  I also want the checkboxes checked after the  
page is refreshed to show the user the current filter applied.


Thanks,

Rob

You''re gonna want "form_remote_tag", the idea is that you
have an
onclick event for the checkbox that uses javascript to submit the form 
data via AJAX.  The AJAX request then updates the right hand side of the 
page.

As for keeping the checkboxes checked, from the action that handles the 
AJAX request, set the session with something like "session[:search] = 
params[:checkboxes]"
