Ruby on rails ArgumentError，创建操作中的参数数错误（3对1）

我使用omniauth gem允许用户注册/登录我的rails应用程序

这是我档案的一部分

gem 'omniauth'
gem 'omniauth-twitter'
gem 'twitter'

Omniauth=is v1.1.4， Omniauth twtter为v0.0.16， Omniauth oauth是v1.0.1， 推特是4.6.2

我遇到了一个类似的错误，因此我尝试卸载Omniauth并将其降级到版本“~>0.2.6”，但我收到了以下消息：

捆绑包当前已将omniauth锁定在1.1.4。 omniauth版本是问题的原因还是其他原因

我试图修复的错误消息是，当我尝试使用Twitter登录时

ArgumentError in AuthenticationsController#create
wrong number of arguments (3 for 1)

app/helpers/sessions_helper.rb:4:in `sign_in'

class UsersController

您已经定义了sign\u in\u和\u redirect以只接受一个参数，但您正在传入两个参数

因此，控制器中的

登录和重定向（：user，authentication.user）

应该变成

登录和重定向（authentication.user）

但有两件事值得注意：

• 您的sign\u-in\u和\u-redirect方法实际上并没有让用户登录，它只是重定向用户
• 如果您使用的是Deviate，那么您将有一个已使用以下签名定义了该名称的方法：

  sign\u in\u和\u redirect（resource\u或\u scope，*args）

  。我建议您要么使用他们的方法（如果您在OmniAuth中使用Deviate），要么将您的方法命名为其他名称，以避免冲突和混淆

---

[实际上，我的分析可能有点不准确，因为堆栈跟踪指向您的sign\u-in方法，而不是sign\u-in\u和\u-redirect-堆栈跟踪中的行号对于您共享的代码是否准确，或者您是否删除了一些代码？]

错误消息很清楚。您正在尝试传递3个参数，而它期望传递一个参数。如何修复此问题？我已经在这一步上停留了一段时间，因此任何帮助都会得到赞赏。嘿，帕特，我注意到，通过将控制器中的代码更改为

sign\u in\u和\u redirect（authentication.user）

会使参数消失，并将用户路由到主页（未登录）。你知道为什么他们的账户没有被创建吗？它以前是工作的，所以不确定它们不会被创造出什么变化？或者只是没有登录？它们将再次被创建，但现在我收到以下错误消息：

undefined method user'for nil:NilClass

。这来自authentications\u控制器中def create内的“登录”（authentication.user）行。方法“user”应该在哪里正确定义？我不确定-你能更新你问题中的代码文件以匹配它们的当前状态吗？我在最后一步。。。我正在尝试实际登录用户。你是对的，它只是重定向他们。如果我没有使用Deviate，那么应该如何定义

登录和重定向

，以及在何处？这真的会帮我很多，所以请让我知道
