轨路由嵌套资源

Question

我旁边资源

resources :countries do 
    resources :cities 
end  

resources :cities do 
    resources :streets 
end 

它生成下一路线

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 

我不想进入城市可以没有国家ID也是我不想用3水平嵌套的资源，所以我可以改变路线如下

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写下所有默认操作：除选项????

Answer 1

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

Answer 2

你可以按照这个路线

 
    resources :topics do 
    resources :solutions 
    end 

    resources :solutions, only: [] do 
    resources :reviews, except: [:show, :index] 
    end
