Yeah, I know it kind of breaks the MVC pattern, but whatever. Its not something you'd want to do all the time, but in the rare instance that you'd like to generate an anchor tag from within a controller, try this:
ActionController.helpers.link_to("Click Me!", awesome_path)
Chances are, whatever you're doing could/should probably be moved into a helper method instead of doing it in the controller, but that's up to you.
