Determine if path exists as route in Rails controller

Question

I want to know if an arbitrary path can be mapped to a route

recognized_request_for accomplishes what I want, but I can't get it to work in my controller.

Specifically, how can I execute recognized_request_for or something that accomplishes the same task from my controller?

Answer 1

For Rails 3 the call is

Rails.application.routes.recognize_path

Instead of

ActionController::Routing::Routes.recognize_path

Example:

def path_exists?(path)
  Rails.application.routes.recognize_path(path)
  true
rescue ActionController::RoutingError
  false
end
