Question

我已经完成了Chapter 6 of railstutorial，但在我添加了password & password_confirmation之后不久，我的所有User model specs都开始失败，并出现以下错误：

用户模型现在可以在here找到了，我已经将源代码和原版进行了比较，但似乎遗漏了一些东西。不知道它是什么

谁能告诉我为什么会出现这个错误？

Answer 1

添加：

attr_accessor :password, :password_confirmation

然后，本教程将使您在password_digest中保存摘要

Answer 2

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

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

Answer 3

我也有同样的问题。我是在Cloud9上做这个的。

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直接放入模型中(或者根本不需要从教程中进行任何代码更改。
