This gem is wrapper on common_numbers library that validates such numbers as:

• NIP (Polish Tax Identification Number)
• PESEL (Polish ID Number)
• REGON (Polish Company Identification Number)

in the future:

• VIN
• EAN
• IBAN

###Instalation

In your Gemfile add:

gem 'common_numbers_rails'

###Example:

For standalone model use common_numbers library

For ActiveRecord Models:

class Item < ActiveRecord::Base
  validates :nip, :nip => true
  validates :pesel, :pesel => true
  validates :regon, :regon => true
end

You can also use helpers:

class Item < ActiveRecord::Base
  validates_pesel_of :pesel_field
  validates_pesel_of :pesel_field, :message => "Our custom message"
end

###TODO:

• validators for other numbers
