Ruby on rails RubyonRails+；中的默认方法无法使缓存片段过期；设计

我在Rails中使用Desive作为身份验证解决方案，我有一个缓存片段：最近的用户

我希望这个片段在新用户注册、更改或删除时过期，因此我将我的（手动创建的）users_controller.rb放入

class UsersController < ApplicationController
    cache_sweeper :user_sweeper, :only => [:create, :update, :destroy]
...

class Users::RegistrationsController < Devise::RegistrationsController
  cache_sweeper :user_sweeper, :only => [:create, :update, :destroy]    
end

class ApplicationController < ActionController::Base
    cache_sweeper :user_sweeper, :only => [:create, :update, :destroy]
...

class UsersController[：创建，：更新，：销毁]
...

但我的片段不会在新创建或更改时过期

我的用户_清扫器包含基本处方

class UserSweeper < ActionController::Caching::Sweeper
observe User

def after_save(user)
   expire_cache(user)
end

def after_destroy(user)
  expire_cache(user)
end

private
  def expire_cache(user)
    expire_fragment :recent_users
  end
end

class UserSweeper

我做错了什么？

问题解决了

我遵循了以下步骤，一切正常：

$ mkdir app/controllers/users
$ touch app/controllers/users/registrations_controller.rb

在注册中\u controller.rb

class UsersController < ApplicationController
    cache_sweeper :user_sweeper, :only => [:create, :update, :destroy]
...

class Users::RegistrationsController < Devise::RegistrationsController
  cache_sweeper :user_sweeper, :only => [:create, :update, :destroy]    
end

class ApplicationController < ActionController::Base
    cache_sweeper :user_sweeper, :only => [:create, :update, :destroy]
...

类用户：：注册控制器<设计：：注册控制器
缓存\u清理器：用户\u清理器，：only=>[：创建，：更新，：销毁]
结束

问题是Desive中的注册是一个单独的控制器。

问题是，DeVICE中的注册是一个单独的控制器。

将其放在applications\u controller.rb中

class UsersController < ApplicationController
    cache_sweeper :user_sweeper, :only => [:create, :update, :destroy]
...

class Users::RegistrationsController < Devise::RegistrationsController
  cache_sweeper :user_sweeper, :only => [:create, :update, :destroy]    
end

class ApplicationController < ActionController::Base
    cache_sweeper :user_sweeper, :only => [:create, :update, :destroy]
...

class ApplicationController[：创建，：更新，：销毁]
...

将其放入应用程序\u controller.rb

class UsersController < ApplicationController
    cache_sweeper :user_sweeper, :only => [:create, :update, :destroy]
...

class Users::RegistrationsController < Devise::RegistrationsController
  cache_sweeper :user_sweeper, :only => [:create, :update, :destroy]    
end

class ApplicationController < ActionController::Base
    cache_sweeper :user_sweeper, :only => [:create, :update, :destroy]
...

class ApplicationController[：创建，：更新，：销毁]
...
