How to define a nested resources for polymorphic models with different namespace?

I am struggling with defining a route in routes.rb to work with nested resources while having a polymorphic association and models with different namespaces.

There are two controllers (I show important lines only):

/app/controllers/project/profile/likes_controller.rb

module Project
 module Profile
  class LikesController < Project::ApplicationController
   def toggle
    ...
   end
  end
 end
end

/app/controllers/project/place/profile/profiles_controller.rb

module Project
 module Place
  module Profile
   class ProfilesController < Project::ApplicationController
   ...
   end
  end
 end
end

... and two models, the first having a polymorphic association called likeable:

/app/models/project/profile/like.rb

module Project
 module Profile
  class Like < ActiveRecord::Base
   ...
   belongs_to :likeable, :polymorphic => true
   ...
  end
 end
end

... and the second model being a likeable:

/app/models/project/place/base.rb

module Project
 module Place
  class Base < ActiveRecord::Base

   has_many :likes, :as => :likeable, :class_name => "Project::Profile::Like", :dependent => :destroy

  end
 end
end

... and this is my route definition as is:

routes.rb

...
scope :module => "project" do

 scope :module => "place" do
  resources :places do
    collection do
      scope :module => "profile" do
        resources :profiles do
            resources :likes
        end
      end
    end
  end
 end

 scope :module => "profile" do
  resources :likes do
   collection do
    post :toggle
   end
  end
 end

end 
...

As we can see, resource likes is a nested resource of resource places.

What I want to achieve?

I want to have a path to the nested resource place/likes, which should point to:

{:action=>"toggle", :controller=>"project/profile/likes"}

and keep the id of the likeable, place_id in this case.

I tried the following:

<%= button_to t(:user_likes), ([likeable, likeable.likes.new]), :action => 'toggle', ... %>

but this results in the following path:

project_place_profile_basis_project_profile_likes_path

which is not correct. The correct path would be project_profile_likes_path.

The following routes are available (rake routes):

profile_likes POST /places/profiles/:profile_id/likes(.:format) {:action=>"index", :controller=>"porject/place/profile/likes"}

and

toggle_likes POST /likes/toggle(.:format) 开发者_如何学C {:action=>"toggle", :controller=>"project/profile/likes"}

Has anyone an idea how to get the path to the controller => project/profile/likes and action => toggle?
