Rails 3 - 過濾器鏈暫停爲：身份驗證呈現或重定向

Question

我仍然在標題中收到「錯誤」消息，不知道如何解決該問題。 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中

#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 
... 

始終時被更新的活性屬性，我會得到的消息 重定向本地主機：3000/ 過濾器鏈停止爲：渲染或重定向認證

我怎樣才能解決這個問題？我試圖搜索谷歌在這裏，所以，但不幸的是，仍然不知道，如何解決它..

Answer 1

我只是與我的用戶之一，得到了該錯誤。

事實證明，用戶有一個字段（我們最近添加了一個長度驗證）與更多的文本比允許的。由於驗證是新的，用戶已經在那裏，這個錯誤一直在顯示。

我發現它時試圖更新其屬性使用「！」使錯誤明確

> User.last.update_attributes!(:email => "someone@domain.com") 

用戶負載（0.3ms的）選擇users。* FROM users ORDER BY users。 id DESC LIMIT 1（0.1毫秒）BEGIN用戶存在（在0.2ms）選擇1 AS一個 FROM users WHERE（users。email = 'someone@domain.com' AND users。id！= 2020）LIMIT 1（0.1毫秒）ROLLBACK 的ActiveRecord :: RecordInvalid：驗證失敗：總結過長 （最大爲650個字符）

因此改變該領域的「摘要」的內容解決它。

Answer 2

當您從before_filter重定向某處時，過濾器鏈會暫停。如果一切正常，可以忽略此消息
