How do you use ActionDispatch::Routing::RouteSet recognize_path?

I want to get the current path for the view.

I tried <div id="<%= ActionDispatch::Routing::RouteSet::recognize_path %>"> but got "undefined method `recognize_path' for ActionDispatch::Routing::RouteSet:Class".

Thanks!

回答1:

Path of the Request:

request.path

Path of the file:

__FILE__

回答2:

You can do this

Rails.application.routes.recognize_path "/your/path"

It works in rails 3.1.0.rc4
