I’ve tried searching the list for this but I’m not really sure what
Rails would call it. Basically what I’m wanting to do is to help
against users changing the URL string, or to help users with expired
bookmarks from the previous version of the site. When a method
doesn’t exist or an action on a method rather then showing “Routing
Error” or “Unknown Action” I want to be able to either forward that to
the 404 error page or just redirect it to my home controller’s index
action. How would one go about doing this?
