我在具有电子邮件字段的Rails应用程序中有一个User模型。是否有默认验证可确保电子邮件格式正确？如果没有，我将如何验证该字段？

最佳答案

添加您的gemfile:

gem 'validates_email_format_of'

并在您的模型中:

validates :email, email_format: { message: "doesn't look like an email address" }

或者，如果您不想使用gem，请使用正则表达式:

validates_format_of :email, :with => /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i
