Question

I’ve checked for the usual spelling mistakes or files in the wrong place. Undoubtedly it will be something simple – but I just can’t see it. What am I missing?

controllers/admin/top_10_pages_controller.rb

class Admin::Top10PagesController < Admin::AdminController

end

models/top_10_page.rb

class Top10Page < ActiveRecord::Base

end

routes.rb

namespace :admin do
  resources :top_10_pages
end

rake routes

admin_top_10_pages     GET    /admin/top_10_pages           admin/top_10_pages#index                      
                       POST   /admin/top_10_pages           admin/top_10_pages#create                            
new_admin_top_10_page  GET    /admin/top_10_pages/new       admin/top_10_pages#new                      
edit_admin_top_10_page GET    /admin/top_10_pages/:id/edit  admin/top_10_pages#edit                     
admin_top_10_page      GET    /admin/top_10_pages/:id       admin/top_10_pages#show                   
                       PUT    /admin/top_10_pages/:id       admin/top_10_pages#update                 
                       DELETE /admin/top_10_pages/:id       admin/top_10_pages#destroy

Bob – I think this is an issue with the name of the controller file itself.

When I run "Top10PagesController".underscore in the console I get "top10_pages_controller" rather than "top_10_pages_controller"

Looks like rails is looking for the wrong controller file. Try changing the controller name to top10_pages_controller.rb and see if that works?
