在我的情况下如何跳过格式验证? [英] how to skip format validation in my case?

问题描述

我有一个属性为guest"(布尔值)的模型用户如果 user.guest == true 或 user.guest == nil，我想跳过电子邮件的格式验证，

I have a model User with an attribute "guest" (BOOLEAN) I want to skip format validation on email if user.guest == true or user.guest == nil,

尝试过

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?

但现在即使用户有来宾 == false 或来宾 == nil 验证仍在跳过

but now even when user have guest == false or guest == nil validation is still skipping

可能有什么问题?

另一个常见的验证效果很好:

another common validation works good:

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

推荐答案

试试这个代码:-

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?
