#url_for(controller, method_name, args = {}) ⇒ Object

Given a controller and methods (and optionally arguments) this generates a the route to get there. If there are named params, its tries to fill them in with the args passed. Failing that, it uses params already in the URL (so that on if the current request is /posts/:post_id (/posts/32), and you call url_for on a routes that is /posts/:post_id/comments, params is automagically filled in with 32. If you want to link to a different posts comment, simply pass :post_id in the args parameter.
