Handling strange Rails URLs

Came across an interesting situation where my Rails application was going to be receiving URLs with characters like (dash) and . (period or dot). Something like this:

http://example.com/my_controller/action-with-odd.characters

Ruby doesn’t allow dashes or periods in identifiers, so this was going to cause a problem with method naming. I couldn’t figure out how to handle this from the web and so I dove into the source and found that when the action method doesn’t exist Rails calls a catch all method called perform_action. Adding my logic to this method worked well. Looks something like this:

def perform_action
  ...
end
