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

### Installation

```ruby
# add this to your Gemfile
gem "credit_card_validation"
```

### and run

```ruby
bundle
```

### Usage

#### With ActiveRecord

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

  # with legacy syntax
  validates_credit_card :card_number

  # with custom message
  validates :card_number, credit_card: { message: "card is not valid?" }
end
```

#### With ActiveModel

```ruby
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.
