Determine if a path exists as a route in a Rails controller

Question

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

detected_request_for does what I want, but I cannot get it to work in my controller.

In particular, how can I perform a recognized_for_for or something that performs the same task from my controller?

Answer 1

DECISION:

@related_page_path = '/' + @page.path
begin
  ActionController::Routing::Routes.recognize_path(@related_page_path, :method => :get)
rescue
  @related_page_path = nil
end

Answer 2

For Rails 3 Challenge

Rails.application.routes.recognize_path

Instead

ActionController::Routing::Routes.recognize_path

Example:

def path_exists?(path)
  begin
    Rails.application.routes.recognize_path(path)
  rescue
    return false
  end

  true
end
