Trouble in Rails 3 Adding Restful Routes to Namespaced Resources

I am trying to add a route to a controller that has been set as a resource开发者_Python百科 in the 'admin' namespace like this:

namespace :admin do
  resources :books do
    collection do
      post :process_new
    end
  end
end

I have added an action int the Admin::BooksController for process_new, but whenever I try to access this action using the url: .../admin/books/process_new I get the following error:

Couldn't find Book with ID=process_new

It looks like it's routing to the show action and trying to use process_new as the id. Can someone shed some light on what I may be doing wrong?

**Edit: I changed my redirects to use the helper functions and it seems to be working.

Add get :process_new to your resources :books routes:

namespace :admin do
  resources :books do
    collection do
      get :process_new
      post :process_new
    end
  end
end
