如何验证 Rails 模型中的两个值不相等? [英] How do I validate that two values do not equal each other in a Rails model?

问题描述

我有一个用户模型，它有一个电子邮件和一个密码字段.为了安全起见，这些可能并不相等.我如何在我的模型中定义它?

I have a User model, which has an email and a password field. For security, these may not be equal to each other. How can I define this in my model?

推荐答案

创建自定义验证:

validate :check_email_and_password

def check_email_and_password
  errors.add(:password, "can't be the same as email") if email == password
end

但请记住，将密码存储为纯文本是个坏主意.您应该将其散列存储.尝试一些身份验证插件，如 authlogic 或 Restful 认证.

But keep in mind that storing password as a plain text is bad idea. You should store it hashed. Try some authentication plugin like authlogic or Restful authentication.
