How can I guess the action name from url in Rails?

Question

For example, I have a url generated by something_pathor methods something_url. I need to know the action name from this URL.

Answer 1

The Rails routing system works in two ways: it recognizes and creates URLs. You need a recognition method, as shown in the following example:

ActionController::Routing::Routes.recognize_path('/mycontroller/myaction', :method => :get)

Assuming the URL was generated with something_pathor something_url, it returns:

{ :action => 'myaction', :controller => 'mycontroller' }

From which you can extract part of the action.

Answer 2

. rake routes / , . HTTP-, .

Answer 3

If you are in view mode, you can use

• action_nameto access the processing action
• controller_nameto access the processing controller

Answer 4

In Rails 3:

Rails.application.routes.recognize_path("http://example.ltd/registrants")
=> => {:action=>"index", :controller=>"registrants"}

If you are in the engine, events

Events::Engine.routes.recognize_path("/registrants")
=> {:action=>"index", :controller=>"events/registrants"}
