Ruby on rails “如何选择路线”；嵌套的；使用“名称空间”或“作用域：模块”/“作用域：路径”的路径？

我使用的是RubyonRails4.2，我希望通过使用

命名空间

或

范围：模块

/

范围：路径

在

资源

块中路由“嵌套”路径

也就是说，我有以下的路线：

resources :users, :only => [:show]

相配

user_path    GET    /users/:id(.:format)    users#show

delete_user_session_path     GET       /users/:user_id/session/delete(.:format)    users/sessions#delete
new_user_session_path        GET       /users/:user_id/session/new(.:format)       users/sessions#new
user_session_path            POST      /users/:user_id/session(.:format)           users/sessions#create
user_session_path            GET       /users/:user_id/session(.:format)           users/sessions#show
                             DELETE    /users/:user_id/session(.:format)           users/sessions#destroy

我想匹配以下路径

users_sessions_path         POST      /users/sessions              users/sessions#create
user_session_path           GET       /users/:id/session           users/sessions#show
delete_user_session_path    GET       /users/:id/session/delete    users/sessions#delete
user_session_path           DELETE    /users/:id/session           users/sessions#destroy

我读了这本书，我试着说

resources :users, :only => [:show] do
  scope :module => :users do
    scope :module => :sessions do 
    # scope :path => :sessions do
    # namespace :sessions do
      ...
    end
  end
end

new_user_session_path        GET       /users/session/new(.:format)       users/sessions#new
user_session_path            POST      /users/session(.:format)           users/sessions#create

但没有一次尝试成功。我该如何陈述路线

在@dgilperez回答后更新

我尝试了以下代码

resources :users, :only => [:show] do
  scope :module => :users do
    resource :session, :only => [:show, :new, :create, :destroy] do
      get :delete, :on => :collection, :to => 'sessions#delete' 
    end
  end
end

相配

user_path    GET    /users/:id(.:format)    users#show

delete_user_session_path     GET       /users/:user_id/session/delete(.:format)    users/sessions#delete
new_user_session_path        GET       /users/:user_id/session/new(.:format)       users/sessions#new
user_session_path            POST      /users/:user_id/session(.:format)           users/sessions#create
user_session_path            GET       /users/:user_id/session(.:format)           users/sessions#show
                             DELETE    /users/:user_id/session(.:format)           users/sessions#destroy

但是我仍然需要映射

new

和

create

操作，而无需传递

：user\u id

参数。也就是说，我想画一些

resources :users, :only => [:show] do
  scope :module => :users do
    scope :module => :sessions do 
    # scope :path => :sessions do
    # namespace :sessions do
      ...
    end
  end
end

new_user_session_path        GET       /users/session/new(.:format)       users/sessions#new
user_session_path            POST      /users/session(.:format)           users/sessions#create

我认为您将它复杂化了：您不需要使用

scope

或

path

来呈现嵌套资源。您只需将其嵌套：

resources :users, :only => [:show] do
  resources :sessions
end

将呈现以下路径：

user_sessions     GET    /users/:user_id/sessions(.:format)            sessions#index
                  POST   /users/:user_id/sessions(.:format)            sessions#create
new_user_session  GET    /users/:user_id/sessions/new(.:format)        sessions#new
edit_user_session GET    /users/:user_id/sessions/:id/edit(.:format)   sessions#edit
user_session      GET    /users/:user_id/sessions/:id(.:format)        sessions#show
                  PATCH  /users/:user_id/sessions/:id(.:format)        sessions#update
                  PUT    /users/:user_id/sessions/:id(.:format)        sessions#update
                  DELETE /users/:user_id/sessions/:id(.:format)        sessions#destroy
user              GET    /users/:id(.:format)                          users#show

这些不是您提到的您需要的路由，但我希望您重新考虑，如果您真的需要这样的路由，使用带名称空间的控制器和自定义名称，例如

delete\u user\u

，或者您更愿意使用更标准的路由。如果你真的需要确切的路线，请告诉我

在OP更新后更新

要使这两条路线丢失，您需要将它们从资源中取出。我会直接这样写：

resources :users, :only => [:show] do
  scope :module => :users do
    resource :session, :only => [:show, :destroy] do
      get :delete, :on => :collection, :to => 'sessions#delete' 
    end
  end
end

get 'users/session/new', to: 'users/sessions#new', as: :new_user_session
post 'users/session', to: 'users/sessions#create'
