authenticate_user！在用户控制器中不起作用 < 设计：：注册控制器

Question

class UsersController < Devise::RegistrationsController
  before_action :authenticate_user! #not working
  # before_action :only_signed_in_user works
  def show
  end
end

only_signed_in_user在哪里

module HeartFillerHelper
  def only_signed_in_user
    unless current_user
      flash[:notice] = 'Devi essere loggato per avere accesso a tale funzione'
      redirect_to root_path
    end
  end
end

问题是我在执行authenticate_user!时没有收到任何错误，我的意思是show的操作被处理得好像没有before_action，这样就会得到经典的nilClass错误@info

这是怎么回事？

您已经从 Devise：：RegistrationsController 继承了 UsersController。

'before_action :authenticate_user!' #does not execute for devise controllers. 

您需要传递"force"属性才能执行。请尝试以下操作：

before_filter ->{ authenticate_user!( force: true ) }
