設計+ omniauth嘰嘰喳喳+認證表

Question

當我通過我的按鈕Twitter登錄身份驗證，我得到這個瀏覽器錯誤

The action 'new' could not be found for RegistrationsController

我創建了一個registrations_controller.rb來覆蓋一些方法的色器件控制器根據本指南http://www.orhancanceylan.com/rails-twitter-and-facebook-authentications-with-omniauth-and-devise/#comment-1375

對不起，代碼冗長。主要部分在authentications_controller.rb中的twitter方法中，在該方法的else部分中。

該代碼部分管理用戶何時沒有其他第三方登錄認證以前創建和未通過設計登錄。因此，必須在代碼的該部分中創建認證記錄和用戶記錄。但我收到錯誤。

有一個認證表，以便我可以添加其他omniauth策略。

如果不清楚，或需要更多信息，請告訴我如何改善問題。

的routes.rb

我是繼承了錯誤的控制器registrations_controller。

應該

class RegistrationsController < Devise::RegistrationsController

不

class RegistrationsController < ApplicationController

看出來，人=]
