Rails 路由：只有自定義操作的資源

Question

我有一個NotificationsController ，其中我只有操作clear 。

我想通過執行 POST /notifications/clear 來訪問此操作

所以我在我的路由器里寫了這個：

  resources :notifications, :only => [] do
    collection do
      post :clear
    end
  end

有沒有更清潔的方法來實現這一目標？ 我想

  scope :notifications do
    post :clear
  end

會這樣做，但我有一個missing controller錯誤，因為 - 我認為 - 它尋找clear控制器。

Answer 1

如果使用示波器，則應添加一個如下所示的控制器

scope :notifications, :controller => 'notifications' do
  post 'clear'
end

或者只是使用命名空間

namespace :notifications do
  post 'clear'
end

Answer 2

post "notifications/clear" => "notifications#clear"

Answer 3

1. 我嘗試了三種組合：

namespace :notifications do
  put :clear
end

scope :notifications, controller: :notifications do
  put :clear
end

resources :notifications, only: [] do
  collection do
    put :clear
  end
end

rails routes:

notifications_clear   PUT /notifications/clear(.:format)  notifications#clear
clear                 PUT /notifications/clear(.:format)  notifications#clear
clear_notifications   PUT /notifications/clear(.:format)  notifications#clear # I choose this

由於 url 助手clear_notifications_* ，我將選擇第三個組合。

2. 此外，實際上我想將這些路由嵌套在資源中：

resources :users do
  namespace :notifications do
    put :clear
  end

  scope :notifications, controller: :notifications do
    put :clear
  end

  resources :notifications, only: [] do
    collection do
      put :clear
    end
  end
end

rails routes:

user_notifications_clear  PUT /users/:user_id/notifications/clear(.:format)  notifications/users#clear
user_clear                PUT /notifications/users/:user_id/clear(.:format)  notifications#clear
clear_user_notifications  PUT /users/:user_id/notifications/clear(.:format)  notifications#clear

最好只使用resources塊only: [] 。

PS我認為通過命名用戶下的通知控制器更有意義：

resources :users, module: :users do
  resources :notifications, only: [] do
    collection do
      put :clear
    end
  end
end

clear_user_notifications  PUT /users/:user_id/notifications/clear(.:format)  users/notifications#clear
