rails路由嵌套资源

Question

我有下一个资源

 resources :countries do
    resources :cities
 end    

 resources :cities do
    resources :streets
 end

它会产生下一条路线

GET    /countries/:country_id/cities(.:format)                          cities#index
POST   /countries/:country_id/cities(.:format)                          cities#create
new_country_city GET    /countries/:country_id/cities/new(.:format)                      cities#new
edit_country_city GET    /countries/:country_id/cities/:id/edit(.:format)                 cities#edit
GET    /countries/:country_id/cities/:id(.:format)                      cities#show
PUT    /countries/:country_id/cities/:id(.:format)                      cities#update
DELETE /countries/:country_id/cities/:id(.:format)                      cities#destroy


......
cities GET    /cities(.:format)                                                cities#index
POST   /cities(.:format)                                                cities#create
new_city GET    /cities/new(.:format)                                            cities#new
edit_city GET    /cities/:id/edit(.:format)                                       cities#edit
city GET    /cities/:id(.:format)                                            cities#show
PUT    /cities/:id(.:format)                                            cities#update
DELETE /cities/:id(.:format)                                            cities#destroy

我不希望访问城市可以没有国家ID但我也不想使用3级嵌套资源,所以我可以改变下一个路线

 resources :countries do
        resources :cities
     end    

     resources :cities, :except => [:index, :destroy, :edit, :show, :create, :new, :update] do
        resources :streets
     end

是否有某种快捷方式禁用所有操作而不是写入所有默认操作:除了选项????

resources :cities, :only => [] do
    ...
end
