Question

我在routes.rb中指定了一些嵌套资源

resources :installation, except: %i[index edit update show] do
     resources :configuration, shallow: true, except: %i[index show] 
end

生成以下路线：

installation_configuration_index POST   /installation/:installation_id/configuration(.:format)     configuration#create
  new_installation_configuration GET    /installation/:installation_id/configuration/new(.:format) configuration#new
              edit_configuration GET    /configuration/:id/edit(.:format)                          configuration#edit
                   configuration PATCH  /configuration/:id(.:format)                               configuration#update
                                 PUT    /configuration/:id(.:format)                               configuration#update
                                 DELETE /configuration/:id(.:format)                               configuration#destroy
              installation_index POST   /installation(.:format)                                    installation#create
                new_installation GET    /installation/new(.:format)                                installation#new
                    installation DELETE /installation/:id(.:format)                                installation#destroy

我现在想向配置中添加一些其他操作，例如enable，disable

resources :installation, except: %i[index edit update show] do
  resources :configuration, shallow: true, except: %i[index show] do
    post :enable
    post :disable
  end
end

其中添加了以下内容：

 configuration_enable POST   /configuration/:configuration_id/enable(.:format)          configuration#enable
 configuration_disable POST   /configuration/:configuration_id/disable(.:format)         configuration#disable

这很好，除了这些新操作使用参数:configuration_id而不是:id之外。这使使用before_actions来检查整个控制器的参数有效性有点烦人。

我想得出类似以下内容的内容：

 configuration_enable POST   /configuration/:id/enable(.:format)          configuration#enable
 configuration_disable POST   /configuration/:id/disable(.:format)         configuration#disable

我已经搜索并找到了使用param: :id或key: id之类的东西，但都没有达到预期的效果。可行但有点混乱的是像这样分别添加新路由：

post 'configuration/:id/enable', action: 'enable', as: 'configuration/enable', to: 'configuration#enable'
post 'configuration/:id/disable', action: 'disable', as: 'configuration/disable', to: 'configuration#disable'
resources :installation, except: %i[index edit update show] do
  resources :configuration, shallow: true, except: %i[index show]
end

在使用嵌套资源的同时，有没有更干净的方法来完成相同的事情？

Answer 1

尝试这个

resources :installation, except: %i[index edit update show] do
  resources :configuration, shallow: true, except: %i[index show] do
    post :enable, :on => :member
    post :disable, :on => :member
  end
end

或这个

resources :installation, except: %i[index edit update show] do
  resources :configuration, shallow: true, except: %i[index show] do
    member do
      post :enable
      post :disable
    end
  end
end

我确定它可以在导轨4/5上使用，但不确定在导轨3上可以使用。编辑：选中，它应该可以工作。

指定其他资源操作的参数名称
