h2. About

This gem adds a very simple IP address format validator to be used with
ActiveRecord models in Rails 3.0. It supports localized error messages.

h2. Installation

Add the gem to your project's @Gemfile@:

<pre><code>
gem 'ip_address_validator'
</code></pre>

h2. Usage

This gem is an @EachValidator@, and thus is used with the @validates@ method:

<pre><code>
class User < ActiveRecord::Base
  validates :last_login_ip,
			ip_address: true
end
</code></pre>

The localization key is @invalid_ip@, and can be specified in the localized
YAML file like so:

<pre><code>
en:
  activerecord:
	errors:
	  messages:
	    invalid_ip: IP address is invalid.
</code></pre>
