# Credit Card Validation

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
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
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.
