Question

我有一个具有属性的模型用户＆＃34;来宾＆＃34; （布尔）如果user.guest == true或user.guest == nil，我想跳过电子邮件的格式验证，

尝试

VALID_EMAIL_REGEX = /^(\S+)@([a-z0-9-]+)(\.)([a-z]{2,4})(\.?)([a-z]{0,4})+$/i
validates :email, format: { :with => VALID_EMAIL_REGEX } unless :guest?

但现在即使用户有guest == false或guest == nil验证仍在跳过

可能出现什么问题？

另一种常见的验证效果很好：

validates :email, presence: true,
                    uniqueness: { case_sensitive: false } unless :guest?

Answer 1

试试这段代码： -

VALID_EMAIL_REGEX = /^(\S+)@([a-z0-9-]+)(\.)([a-z]{2,4})(\.?)([a-z]{0,4})+$/i
validates :email, presence: true, format: {with: VALID_EMAIL_REGEX},
uniqueness: {case_sensitive: false},  unless: :guest?

如何在我的情况下跳过格式验证？
