【问题描述】：

我刚开始学习 Ruby on Rails，并在一个具有以下设置的简单网站上工作：

  resources :categories do
    resources :products
  end

  resources :products do
    resources :features
  end

但是我不想将 url 暴露给products_controller

/products(.:format)                                  products#index
/products(.:format)                                  products#create
/products/new(.:format)                              products#new
/products/:id/edit(.:format)                         products#edit
/products/:id(.:format)                              products#show
/products/:id(.:format)                              products#update
/products/:id(.:format)                              products#update
/products/:id(.:format)                              products#destroy

我只需要如下所示的路线

/products/:product_id/features(.:format)             features#index
/products/:product_id/features(.:format)             features#create
/products/:product_id/features/new(.:format)         features#new
/features/:id/edit(.:format)                         features#edit
/features/:id(.:format)                              features#show
/features/:id(.:format)                              features#update
/features/:id(.:format)                              features#update
/features/:id(.:format)                              features#destroy

我知道上面的路由可以通过标记shallow: true 来完成，但是它仍然会暴露给products_controller 的restful 路径，还有这个问题吗？

【解决方案1】：

您可以使用 only 或 except 将其限制为您想要的操作。仅与空数组一起使用应该会删除路由。

  resources :categories do
    resources :products
  end

  resources :products, only: [] do
    resources :features
  end

所以现在如果我耙路线

 category_products GET    /categories/:category_id/products(.:format)                                  products#index
                                       POST   /categories/:category_id/products(.:format)                                  products#create
                  new_category_product GET    /categories/:category_id/products/new(.:format)                              products#new
                 edit_category_product GET    /categories/:category_id/products/:id/edit(.:format)                         products#edit
                      category_product GET    /categories/:category_id/products/:id(.:format)                              products#show
                                       PATCH  /categories/:category_id/products/:id(.:format)                              products#update
                                       PUT    /categories/:category_id/products/:id(.:format)                              products#update
                                       DELETE /categories/:category_id/products/:id(.:format)                              products#destroy
                            categories GET    /categories(.:format)                                                        categories#index
                                       POST   /categories(.:format)                                                        categories#create
                          new_category GET    /categories/new(.:format)                                                    categories#new
                         edit_category GET    /categories/:id/edit(.:format)                                               categories#edit
                              category GET    /categories/:id(.:format)                                                    categories#show
                                       PATCH  /categories/:id(.:format)                                                    categories#update
                                       PUT    /categories/:id(.:format)                                                    categories#update
                                       DELETE /categories/:id(.:format)                                                    categories#destroy
                      product_features GET    /products/:product_id/features(.:format)                                     features#index

                                       PUT    /products/:product_id/features/:id(.:format)                                 features#update
                                       DELETE /products/:product_id/features/:id(.:format)                                 features#destroy

谢谢你成功了！我认为可能有一些特殊的属性可以设置来获得我需要的东西，但我想这是唯一的方法！
据我所知，这是我过去的做法。如果有什么特别的方法我很想知道。
