Vat-Id validator

A validator for VAT-ID based on ActiveModel::EachValidator.

Add this line to your application's Gemfile:

gem 'vat_id_validator'

And then execute:

$ bundle

Or install it yourself as:

$ gem install vat_id_validator

Your model must respond to #errors with an instance of ActiveModel::Errors. Then include ActiveModel::Validations:

class FinancialSettings
  extend ActiveModel::Naming
  include ActiveModel::Validations

  attr_reader :errors
  attr_accessor :tax_number

  def initialize
    @errors = ActiveModel::Errors.new(self)
  end

  validates :tax_number, :vat_id => true

  # ...
end
