Do not modify the value in your database.

I mean the controller that is being called by your AJAX request. It is entirely possible this in not your Rails app, but I would think it would be. You have to look at your javascript and find the AJAX call, then look at the url in that call to find the route it's seeking, and match that route to the controller. You can find out which routes map to controllers by running `rake routes`.
