SpanishVatValidators

I've adapted the code from the ValidateSpanishVAT plugin from https://github.com/lleirborras/ValidateSpanishVAT to be distributed as a gem for ease of use with Rails >= 3.2.

Also added I18n support for error messages, which you can change by adding this to your locale yml:

es:
  errors:
    messages:
      not_valid_spanish_vat: El número de identificación fiscal no es válido
      not_valid_spanish_id: El NIF/NIE no es válido
      not_valid_nif: El NIF no es válido
      not_valid_cif: El CIF no es válido
      not_valid_nie: El NIE no es válido

Installation

Add this line to your application's Gemfile:

gem 'spanish_vat_validators'

And then execute:

$ bundle

Or install it yourself as:

$ gem install spanish_vat_validators

Usage

Just use any of the following validators.

# A person id
class Spaniard < ActiveRecord::Base
  validates :dni, :valid_nif => true
end

# A company id
class Company < ActiveRecord::Base
  validates :cif, :valid_cif => true
end

# A foreigner id
class Alien < ActiveRecord::Base
  validates :nie, :valid_nie => true
end

# Any person id
class Person < ActiveRecord::Base
  validates :any_id, :valid_spanish_id => true
end

# Any kind of id is valid
class SpanishSubject < ActiveRecord::Base
  validates :nif, :valid_spanish_vat => true
end

You can override the error message using the message option.

class Person < ActiveRecord::Base
  validates :dni, valid_nif: { message: 'invalid' }
end
