National IDs Validator for Ruby on Rails (Active Model)

It provides validators for national identification numbers. Currently the following countries are supported:

Usage

Add to your Gemfile:

gem 'national-ids-validator'

Run:

bundle install

Then add the following to your model:

validates :personal_id_attribute, :national_id => {country: "PL"}

A custom error message can be provided:

validates :personal_id_attribute, :national_id => {country: "PL", message: "is not valid personal number"}

If the nil value should be allowed, it need to be explicitely stated:

validates :personal_id_attribute, :national_id => {country: "PL", allow_nil: true}

Often personal number contains useful data like birth date and/or gender. You may use the following commands to retrieve them:

gender ruby require 'national_ids_validator' NationalIdsValidator.new("12030599592", "NO").gender %returns 0 It will return 0 for man, 1 for woman and nil for invalid number.
