我一直关注 Michael Hartl 的http://ruby.railstutorial.org直到第 6.3.2 章，在那里我停留在密码和确认。（http://ruby.railstutorial.org/chapters/modeling-users#sec:adding_a_secure_password）
在阅读了以下说明后，我根据我的理解将“attr_assessor :password, :password_confirmation”添加到了 User.rb 中：
“如图 6.1 中的模型所示，我们希望用户确认他们的密码，这是网络上的一种常见做法，旨在最大程度地减少拼写错误。我们可以在控制器层强制执行此操作，但将其放入模型中并使用是常规做法Active Record 强制约束。方法是在 User 模型中添加 password 和 password_confirmation 属性，然后要求这两个属性匹配才能将记录保存到数据库中。与我们目前看到的其他属性不同，密码属性将是虚拟的——它们只会暂时存在于内存中，不会持久化到数据库中。”
添加后，我在 user_spec.rb 上的 bundle exec guard 上出现 11 次失败：
password: "foobar", password_confirmation: "foobar" to @User.new in models/user_spec.rb
类似于 db:development.sqlite3 中不存在的“虚拟”属性（密码、密码确认）。这就是我试图做的没有成功的事情。我什至尝试了所有可能的方法，例如在 user.rb 中使用 @User 的哈希
我在这里做错了什么？
