map.namespace :admin do |admin|
    # Directs /admin/products/* to Admin:roductsController (app/controllers/admin/products_controller.rb)
    admin.resources :types
    admin.namespace :types do |types|
      types.resources :products,:collection => {:list => :get}
      types.namespace :products do |products|
        products.resource :infos
      end
    end
end

怎么不能实现多级嵌套吗?

复制内容到剪贴板

代码:

  map.resources :types do |type|
    type.resources :products do |product|
      product.resources :infos
    end
  end

这样看看 行么?
