Question

当我通过我的Twitter登录按钮进行身份验证时，我收到此浏览器错误

The action 'new' could not be found for RegistrationsController

我创建了一个registrations_controller.rb来根据本指南覆盖某些方法的设计控制器http://www.orhancanceylan.com/rails-twitter-and-facebook-authentications-with-omniauth-and-devise/#comment-1375

很抱歉这些代码很冗长。主要部分位于authentications_controller.rb方法的twitter中，位于方法的else部分中。

当用户没有先前创建的其他第三方登录身份验证且未通过设备登录时，该部分代码将受到管理。因此，必须在代码的该部分中创建认证记录和用户记录。但是我收到了错误。

有一个身份验证表，以便我可以添加其他omniauth策略。

如果不清楚或需要更多信息，请告诉我如何改进这个问题。

Answer 1

我从错误的控制器继承了registrations_controller。

应该是

class RegistrationsController < Devise::RegistrationsController

不是

class RegistrationsController < ApplicationController

小心，伙计=]

设计+ omniauth twitter +认证表
