Rails - Find out where a url-helper points

In rails, when I have a form with a path-helper, for instance create_admin_shop_voucher_path and I want to find out what controller action it points to, I look in routes.rb:

rake routes | grep 'create_admin_shop_voucher'

But how do I do the same for a url-helper, for instance passed_url ?

Lets say you have this route in your RAILS_ROOT/config/routes.rb file

get "passed" => "passed#index", :as => :passed

If you call passed_url

rails will return the whole url. For instance http://localhost:3000/passed

if you call passed_path

rails will return the relative path /passed

*_url helper generates a URL that includes the protocol and host name. The *_path helper generates only the path portion.

So, the its the same route in your RAILS_ROOT/config/routes.rb file

In your case you can call create_admin_shop_voucher_url as well as create_admin_shop_voucher_path.

Mostly you should use the _path flavor. If you need to spec the host or protocol (like for talking to another app or service), then use the _url flavor.

I use _url when i want to pass for instance a subdomain to a link.
