use*_*805 3 email validation ruby-on-rails blacklist
我目前正在尝试使用一些东西来验证电子邮件属性:
我陷入了第四步,我真的不知道如何实现它,这个步骤的主要部分是排除可抛出的邮件提供者.
我现在这个:
validates :email, :presence => true,
:format => { :with => email_regex },
:uniqueness => { :case_sensitive => false },
:exclude => Not working when I put a regex here

我的问题不是正则表达式,而是如何排除与排除正则表达式的电子邮件匹配.
你能帮帮我吗?
亲切的,罗布.
如果您使用devise进行用户身份验证,则可以取消注释devise.rb中的代码
# Email regex used to validate email formats. It simply asserts that
# one (and only one) @ exists in the given string. This is mainly
# to give user feedback and not to assert the e-mail validity.
# config.email_regexp = /\A[^@]+@[^@]+\z/

否则我觉得你可以这样写
在模型中
validates :email, uniqueness: true
validate :email_regex
def email_regex
if email.present? and not email.match(/\A[^@]+@[^@]+\z/)
errors.add :email, "This is not a valid email format"
end
end

格式验证器有一个无选项(至少在rails 4和3.2中),所以......
validates :email, :presence => true,
:format => { :with => email_regex},
:uniqueness => { :case_sensitive => false }
validates :email, :format => {:without => some_regex}
