Question

我遇到嵌套资源问题。

2型号

User => has_many :stuffs

Stuff => belongs_to :user

的routes.rb

map.resources :stuffs

map.resources :users, :has_many => [:stuffs]

当我调用/ users / 1 / stuffs时，它会向我显示相应用户的Stuff。但是当我打电话给/ users / 2 / stuffs时我也得到了这个。它应该返回0“Stuffs”但它不起作用。

MySQL Query from Server
SELECT * FROM `stuffs`

rake routes

stuffs GET    /stuffs(.:format)                         {:action=>"index", :controller=>"stuffs"}
                POST   /stuffs(.:format)                         {:action=>"create", :controller=>"stuffs"}
      new_stuff GET    /stuffs/new(.:format)                     {:action=>"new", :controller=>"stuffs"}
     edit_stuff GET    /stuffs/:id/edit(.:format)                {:action=>"edit", :controller=>"stuffs"}

                DELETE /users/:user_id/stuffs/:id(.:format)      {:action=>"destroy", :controller=>"stuffs"}
          users GET    /users(.:format)                          {:action=>"index", :controller=>"users"}
                POST   /users(.:format)                          {:action=>"create", :controller=>"users"}
       new_user GET    /users/new(.:format)                      {:action=>"new", :controller=>"users"}
      edit_user GET    /users/:id/edit(.:format)                 {:action=>"edit", :controller=>"users"}
           user GET    /users/:id(.:format)                      {:action=>"show", :controller=>"users"}
                PUT    /users/:id(.:format)                      {:action=>"update", :controller=>"users"}
                DELETE /users/:id(.:format)                      {:action=>"destroy", :controller=>"users"}
           root        /                                         {:action=>"index", :controller=>"users"}

对应的user_id没有where子句。但是如何解决呢？

希望有人可以提供帮助

Answer 1

在你的Stuffs控制器的索引方法中，你是如何收集你的东西的？如果您使用脚手架来创建控制器，它将默认为

@stuffs = Stuff.all

但应该是

的内容

@user = User.find(params[:user_id])
@stuffs = @user.stuffs

或其他相似的东西 - 基本上，你收集用户的东西，而不是所有的东西。

Answer 2

默认情况下，Rails控制器不会过滤您的结果。如上所述，由于您可能在StuffsController中调用Stuff.all，因此它将始终返回所有Stuff对象。

我使用inherited_resources作为我网站上的默认行为。它会自动处理这些关系，并允许您在需要不同的行为时覆盖它们：

Answer 3

单独的路线不会影响模型。但是，由于传入了用户ID，您可以执行以下操作：

User.find(params[:user_id]).stuffs

Answer 4

试试这个

map.resources :users do |users|
  users.resources :stuffs
end
