# IsbnValidation

Custom ActiveRecord Validation for International Standard Book Number (ISBN)

fields. Supports both ISBN-10 and ISBN-13. Will guarantee that validated fields

contain valid ISBNs.

Default behaviour is to allow either ISBN-10 or ISBN-13, but this can be

altered by specifying the :with option as shown in the example below.

For more information on ISBN, see http://en.wikipedia.org/wiki/Isbn

## Installation

To use it, add it to your Gemfile:

    gem 'isbn_validation'

The current version of isbn_validation only supports Rails 3+. For Rails 2.x

support, please use v0.1.2.

## Example

    class Book < ActiveRecord::Base

      validates :isbn,   :isbn_format => true

      validates :isbn10, :isbn_format => { :with => :isbn10 }

      validates :isbn13, :isbn_format => { :with => :isbn13 }

    end
