ruby-on-rails - 嵌套资源问题 [英] ruby-on-rails - Problem with Nested Resources

问题描述

我在使用嵌套资源时遇到问题.

I have a Problem with Nested Resources.

2 个模型

User => has_many :stuffs

Stuff => belongs_to :user

routes.rb

map.resources :stuffs

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

当我调用/users/1/stuffs 时，它会为我显示相应用户的 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.

When i call /users/1/stuffs it presents me the Stuff for the corresponding User. but i got this also when i call /users/2/stuffs. It should return 0 "Stuffs" but it dont work.

MySQL Query from Server
SELECT * FROM `stuffs`

推荐答案

在你的 Stuffs 控制器的 index 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，它将默认为类似

In your Stuffs controller's index method, how are you collecting your stuffs? If you used a scaffold to create the controller it will default to something like

@stuffs = Stuff.all

但应该类似于

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

或者类似的东西——基本上，你收集的是用户的东西，而不是所有的东西.

or something to that effect--basically, you're collecting the user's stuff, not all stuff.
