ruby-on-rails - 在 rails 上验证数组 mongoid 和 ruby

Question

我在模型 Invitation 中有一个字段和属性，例如:

field :recipients, :type => Array

我的 Controller 中有一个包含 4 封电子邮件的数组，例如:

@invitation.recipients = ['', '', '', '']

我想在我的模型中验证每个数组的值是否与电子邮件正则表达式相匹配，例如:

validates_format_of :recipients, :with => /^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/u, :message => "is not a valid email address"

如何在 mongoid 中验证数组的正则表达式？

Answer 1

怎么样:

RE = /^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/u
validate :recipients_format
def recipients_format
  unless recipients.all? { |r| r =~ RE }
    errors[:recipients] = "are not all valid email addresses"
  end
end
