ip_address_validator

Simple IP validator for Rails 3+

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.

Add the gem to your project's Gemfile:

gem "ip_address_validator"

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

class User < ActiveRecord::Base
  validates :last_login_ip,
            ip_address: true
end

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

en:
  activerecord:
	errors:
	  messages:
	    invalid_ip: IP address is invalid.
