错误:重定向太多

我正在使用devise并尝试下一个:

class ApplicationController < ActionController::Base
   protect_from_forgery
   before_filter :is_worker

   def is_worker
     if user_signed_in?
        @email = current_user.email
        if @email && Worker.find_by_email(@email).nil?
          redirect_to '/tasksadmins'
        else
           redirect_to '/workers'
        end
     else
         redirect_to '/users/sign_in'
     end
   end
end

当我尝试进入网站时:localhost:3000/tasksadmins,我得到了:

Oops! It was not possible to show this website

The website at http://localhost:3000/tasksadmins seems to be unavailable. The precise error was:

Too many redirects

It could be temporarily switched off or moved to a new address. Don't forget to check that your internet connection is working correctly.

我该如何解决?

2 个答案:

答案 0 :(得分:7)

before_filter适用于每个请求。这就是为什么它一次又一次地重定向。

您可能只希望过滤特定操作:

before_filter :is_worker, only: :index

另一个解决方案是检查#is_worker中是否需要重定向:

redirect_to '/workers' unless request.fullpath == '/workers'

修改

另一种方法是跳过重定向目标操作的前置过滤器。例如:

class WorkersController < ApplicationController

  skip_before_filter :is_worker, only: :index

  # …

end

答案 1 :(得分:0)

就我而言:

users_controller.rb

  before_action :logged_in?, only: :new

  def new
    @user = User.new
    render layout: "session"
  end

application_controller.rb

def logged_in?
    redirect_to users_new_url unless current_user.present?
end

当我尝试重定向到“用户/新”页面时,发生了相同的错误。 这仅仅是因为我试图重定向到'users / new'页面,并且“ def logging_in?” 也正在重定向到同一页面。

然后,我更改了 application_controller.rb 代码,如下所示:

def logged_in?
    redirect_to root_url unless current_user.blank?
end

错误已解决。
