问题
I have a Problem with Nested Resources.
2 Models
User => has_many :stuffs
Stuff => belongs_to :user
routes.rb
map.resources :stuffs
map.resources :users, :has_many => [:stuffs]
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`
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"}
stuff GET /stuffs/:id(.:format) {:action=>"show", :controller=>"stuffs"}
PUT /stuffs/:id(.:format) {:action=>"update", :controller=>"stuffs"}
DELETE /stuffs/:id(.:format) {:action=>"destroy", :controller=>"stuffs"}
user_stuffs GET /users/:user_id/stuffs(.:format) {:action=>"index", :controller=>"stuffs"}
POST /users/:user_id/stuffs(.:format) {:action=>"create", :controller=>"stuffs"}
new_user_stuff GET /users/:user_id/stuffs/new(.:format) {:action=>"new", :controller=>"stuffs"}
edit_user_stuff GET /users/:user_id/stuffs/:id/edit(.:format) {:action=>"edit", :controller=>"stuffs"}
user_stuff GET /users/:user_id/stuffs/:id(.:format) {:action=>"show", :controller=>"stuffs"}
PUT /users/:user_id/stuffs/:id(.:format) {:action=>"update", :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"}

There is no where clause for the corresponding user_id. But how to fix it?
Rails Version 2.3.8
Should work like this => http://guides.rubyonrails.org/routing.html 2.7 Nested Resources
Hope somebody can help
回答1:
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
but should be something along the lines of
@user = User.find(params[:user_id])
@stuffs = @user.stuffs
or something to that effect--basically, you're collecting the user's stuff, not all stuff.
回答2:
Rails controllers will not filter your results by default. As above, since you're probably calling Stuff.all in your StuffsController, it will always return all Stuff objects.
I use inherited_resources for the default behaviour on my sites. It handles these relationships automatically and lets you override it when you want different behaviour:

回答3:
Routes alone don't affect the model. Since the user id is passed in, though, you can do:
User.find(params[:user_id]).stuffs
回答4:
Try this
map.resources :users do |users|
users.resources :stuffs
end
