我已经完成了 railstutorial 的第 6 章，但是在我添加&后，我的所有用户模型规范都开始失败，并出现以下错误：passwordpassword_confirmation

用户模型可以在这里找到现在，我已经将源代码与原始模型进行了比较，但似乎我遗漏了一些东西。不要它是什么

谁能告诉我为什么会出现这个错误？

has_secure_password如果您还没有这样做， 只需添加到用户模型文件中。

class User < ActiveRecord::Base
 attr_accessible :email, :name, :password, :password_confirmation
 has_secure_password
 # ..
end

添加：

attr_accessor :password, :password_confirmation

然后，本教程将使您将摘要保存在password_digest

我只是有同样的问题。我在 Cloud9 上做这个。

我注意到我的测试也没有全部运行。

刷新我的文件树解决了这两个问题。

我不需要将 :password 或 :password_confirmation 直接放在模型中（或者根本不需要从教程中进行任何编码更改。

我最终花了几个小时，找不到任何答案。我的问题最终出现在小写线上：

before_save { self.email = email.downcase }

他指定你可以用我做的不同方式来做这条线。见下文。

https://www.railstutorial.org/book/_single-page#sec-creating_and_authenticating_a_user

在代码清单 6.31 中，我们可以将赋值写成 self.email = self.email.downcase（其中 self 指代当前用户），但在 User 模型中，右侧的 self 关键字是可选的：self.email = email.downcase

不要这样做。它每次都给我错误消息，直到我恢复 before_save { self.email = email.downcase }

并删除： self.email = self.email.downcase

我是一个菜鸟，所以不完全确定为什么这会有所作为，但确实如此。

它正在产生这些错误，因为第一个before {}块试图添加 User 模型未指定的两个属性 -password和password_confirmation.

因为这个before {}块在每次测试之前运行（这就是重点），所以每次测试都会出错并且它们都失败了。这并不是说测试本身失败了，而是ActiveRecord不知道如何处理这些属性，并且在每个测试真正运行之前都会产生错误：

ActiveRecord::UnknownAttributeError:
unknown attribute: password

正如codeneko的回答所说，只需在教程中前进并放入has_secure_password用户模型文件即可解决此问题。这告诉ActiveRecord接受password和password confirmation属性，所有测试都将通过。

不幸的是，教程会立即告诉您注释掉，has_secure_password因此在教程让您取消注释之前，使用潜水的答案作为替代可能不是一个坏主意。

我认为 attr_accessor :password, :password_confirmation为用户模型添加的公认答案是错误的。因为如果has_secure_password虚拟地创建这些属性，这意味着它出于某种原因（安全性）这样做。因此，解决方案可能是在您创建用户测试对象的任何地方调用 BCrypt：

require 'bcrypt'

    @user = User.new(name: 'test', password: BCrypt::Password.create("my password"), password_confirmation: 'my password')

我在这篇文章中写道：

Rails - 未知属性密码

如果我错了，请纠正我。
