Get full rails controller name, including the namespace

Question

I've many controllers in different namespaces. The controller_name method only returns the name of the controller, e.g. 'articles'. Is there any chance to get the full name like 'service/articles' (the articles controller is in the service namespace)?

I want do create a link to the index action of each controller via a globally used partial:

<%= link_to controller.display_name, { :controller => controller.controller_name, :action => "index"} %>

If this partial is rendered in a view in the 'users' namespace, I get an error: users/articles has no route (it should be service/articles).

Answer 1

Have you tried:

controller_path

http://api.rubyonrails.org/classes/AbstractController/Base.html#method-i-controller_path

Answer 2

Instead of linking to the :controller, :action syntax, can you use nested resources

routes.rb

resources :users do
  resources: articles
end

in your view

= link_to 'Articles', user_article_path(current_user)

The user_article will take care of your namespaces for you.
