我仍然收到标题中的“错误”消息，但不知道如何解决。 在 ApplicationController 中，

class ApplicationController < ActionController::Base
   protect_from_forgery
   before_filter :mailer_set_url_options
   helper_method :current_user_session, :current_user

   def mailer_set_url_options
     ActionMailer::Base.default_url_options[:host] = request.host_with_port
   end

   private
      def current_user_session
        logger.debug "ApplicationController::current_user_session"
        return @current_user_session if defined?(@current_user_session)
        @current_user_session = UserSession.find
      end

      def current_user
        logger.debug "ApplicationController::current_user"
        return @current_user if defined?(@current_user)
        @current_user = current_user_session && current_user_session.user
      end

      def authentication
        logger.debug "ApplicationController::authentication"
        unless current_user
          store_location
          flash[:warning] = "You must be logged out to access this page"
          redirect_to root_url
          return false
        end
      end

      def store_location
        session[:return_to] = request.url
      end
end

在routes.rb

  #match 'set_activity_account/:id/:value' => 'users#account_activity', :as => :set_activity_account -- this doesn't work as well..
  resources :users do
    member do
      get :action_a, :action_b
    end
    collection do
      get 'account_activity'
    end
  end

和UsersController

class UsersController < ApplicationController
  before_filter :authentication, only: [:index, :edit, :update, :destroy, :action_a, :action_b]
  #skip_before_filter :authentication, :only => [:account_activity] didn't help as well

  def account_activity
    unless current_user.nil?
      puts 'A'
      if params[:user_id] && params[:status]
        puts 'B'
        User.find(params[:user_id]).update_attributes(:active => params[:status])
        flash[:notice] = 'Activity was successfully changed.'
      end
    end
    redirect_to :back
  end
...

总是在更新 active 属性时，我会收到消息 重定向 localhost:3000/ 过滤器链停止为:身份验证呈现或重定向

编辑: 添加日志文件的输出:

我该如何解决这个问题？我试过在谷歌上搜索 SO，但不幸的是仍然不知道如何解决它..

最佳答案

当您从 before_filter 重定向到某处时，过滤器链会停止。如果一切正常，您可以忽略此消息

关于ruby-on-rails - Rails 3 - 过滤器链暂停为 :authentication rendered or redirected，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12631278/
