You should check the guide to understand the routing: http://guides.rubyonrails.org/routing.html#controller-namespaces-and-routing

I think this question is very similar to:

Rails Controller Namespace

And as shortage:

Rails will detect the namespace automagically by the folder. So you don't need to append it to the name:

This blog post explains it so well:

Let's say we have an Invoice class and each invoice can have multiple invoice items:

class Invoice < ActiveRecord::Base
  has_many :items
end

class Item < ActiveRecord::Base
  belongs_to :invoice
end

Clearly Invoice is a composition of Items and an Item cannot live without a containing Invoice. Other classes will probably interact with Invoice and not with Item. So let's get Item out of the way by nesting it into the Invoice namespace. This involves renaming the class to Invoice::Item and moving the source file to app/models/invoice/item.rb:

 class Invoice::Item < ActiveRecord::Base
   belongs_to :invoice
 end

Same is applied to controllers and views.
