Question

我要重写Devise：RegistrationController，我需要添加一个before filter身份验证功能，该功能在我的应用程序的BaseController中如何在filter之前添加该功能。我在扩展Devise：RegistrationsController且无法扩展basecontroller时遇到了这个问题

Answer 1

创建关注点，然后在两个控制器中都包含该关注点：

## app/controllers/concerns/concern_with_the_method_i_want.rb

module ConcernWithTheMethodIWant
  def method
    return 'This is the method'
  end
end

class BaseController < ApplicationController
  include ConcernWIthTheMethodIWant
end

class RegistrationController < Devise::RegistrationController
  include ConcernWithTheMethodIWant
end

这将使您能够做到：

BaseController.new.method
=> 'This is the method'

Devise:RegistrationController.new.method
=> 'This is the method'

在我已经扩展了Devise：registrationsController的类中从basecontroller的过滤器之前添加
