ruby-on-rails - Problem with Nested Resources

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"}
                DELETE /users/:id(.:format)                      {:action=>"destroy", :controller=>"users"}
           root        /                                         {:action=>"index", :controller=>"users"}

gem list

actionmailer (2.3.8)
actionpack (2.3.8)
activerecord (2.3.8)
activeresource (2.3.8)
activesupport (2.3.8)
arel (2.0.6)
authlogic (2.1.6)
builder (2.1.2)
cgi_multipart_eof_fix (2.5.0)
gem_plugin (0.2.3)
i18n (0.5.0)
mongrel (1.1.5 x86-mingw32)
mysql (2.8.1 x86-mingw32)
paperclip (2.3.7)
rack (1.1.0)
rails (2.3.8)
rake (0.8.7)
tzinfo (0.3.23)

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

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:

Try this 

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

Routes alone don't affect the model. Since the user id is passed in, though, you can do:

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

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.
