Overview

ActiveModel CreditCardExpirationValidator

Validates a card expiration date held in a single attribute as a parseable string (MM/YY, MM/YYYY, MMYY, …).

class Payment
  include ActiveModel::Validations
  attr_accessor :expiration

  validates :expiration, credit_card_expiration: true
end

For forms with separate month + year fields, use the Expiration class directly in a plain validate block (see README).
