Ya, I am not doing an ajax call because it is not really needed. I can
possibly have new equipment and that would require more maintenance to tell
the ajax call where to go for that piece of eqpt. The way I am doing would
just require an array entry and a controller action. Anyway, I got it to
work by doing this in the view:
$('shelfcards').innerHTML = (<%= render :partial => 'turin2000' %>);
