设计+ omniauth叽叽喳喳+认证表

Question

当我通过我的按钮Twitter登录身份验证，我得到这个浏览器错误

The action 'new' could not be found for RegistrationsController

我创建了一个registrations_controller.rb来覆盖一些方法的色器件控制器根据本指南http://www.orhancanceylan.com/rails-twitter-and-facebook-authentications-with-omniauth-and-devise/#comment-1375

对不起，代码冗长。主要部分在authentications_controller.rb中的twitter方法中，在该方法的else部分中。

该代码部分管理用户何时没有其他第三方登录认证以前创建和未通过设计登录。因此，必须在代码的该部分中创建认证记录和用户记录。但我收到错误。

有一个认证表，以便我可以添加其他omniauth策略。

如果不清楚，或需要更多信息，请告诉我如何改善问题。

Answer 1

我是继承了错误的控制器registrations_controller。

应该

class RegistrationsController < Devise::RegistrationsController

不

class RegistrationsController < ApplicationController

看出来，人=]
