Namespace with index action in Rails

I have an admin controller located inside /controllers/admin/admin_controller.rb I also have a pages controller located inside /controllers/admin/pages_controller.rb In my routes.rb file, I have the following:

  map.namespace :admin do |admin|
    admin.resources :pages
  end

When the user goes to localhost:3000/admin, I'd like the user to see a page with a link to /admin/pages (Pages CRUD) and to / (To go back home). Since I am using a namespace, I cannot have an index action for /admin. H开发者_高级运维ow would I get this done and still have my controllers located inside my /controllers/admin folder (rather than using admin as a map.resources component and a has_many association to pages). Please note I am only interested in the show action of admin.

You can have an index action for /admin:

map.namespace :admin do |admin|
  admin.root :controller => "pages"
end
