可确认设计的路由

Question

我已经实现了 Devise Confirmable，它工作正常。当用户第一次注册时：

• 重定向到 localhost:3000/en 的应用程序根目录

• Flash 通知显示“带有确认链接的消息已发送到您的电子邮件地址。请打开链接以激活您的帐户。”

到目前为止一切顺利。

然后我更新了应用程序控制器：

class ApplicationController < ActionController::Base
    before_filter :authenticate_user!
end

然后，新注册的用户会发现自己被重定向到 localhost:3000/en/users/sign_in，并显示令人困惑的消息“您需要先登录或注册才能继续。”

我一直在浏览 Devise how to's，但还没有破解它。解决此问题的最简单方法是什么？

更新

这里是应用控制器的更多细节：

class ApplicationController < ActionController::Base
  protect_from_forgery                                  
  before_filter :authenticate_user!
  before_filter :set_i18n_locale_from_params

  rescue_from CanCan::AccessDenied do |exception|
    flash[:error] = "Access denied!"
    redirect_to root_url
  end

  protected

  def set_i18n_locale_from_params
        ...
  end
end

更新

这是所要求的日志。

在 routes.rb 我有：

root :to => "page#index"

所以发生的事情是 PageController#index 正在重定向用户登录。所以问题归结为如何仅从 :authenticate_user 中排除这个！在应用程序控制器中。

分辨率

感谢jibiel 和this question，答案是：

  class PageController < ApplicationController
    skip_before_filter :authenticate_user!
  end

简单！

Answer 1

before_filter :authenticate_user!, :unless => :devise_controller?

并且devise will handle 自己对其控制器操作进行身份验证。否则，您将覆盖它们，因为它们 预先添加 到您的 before_filter。
