# Credit Card Validation

This gem adds the capability of validating credit cards to ActiveRecord and ActiveModel (Rails 3+) and Ruby 1.9.2+.

### Installation
    # add this to your Gemfile
    gem "credit_card_validation"

    # and run
    bundle

### Usage

#### With ActiveRecord
    class Order < ActiveRecord::Base
      # standard validation
      validates :card_number, credit_card: true

      # with legacy syntax
      validates_credit_card :card_number
    end

#### With ActiveModel
    class Order
      include ActiveModel::Validations

      attr_accessor :card_number

      validates :card_number, credit_card: true
    end

#### I18n

The default error message `is not a valid credit card`.
You can pass the `message: "my custom error"` option to your validation to define your own, custom message.
