Romanian Validators

Validators for:

Cod Numeric Personal (CNP)
Cod de identificare fiscală (CIF) and
IBAN (only Romanian format as published by Romanian National Bank).
BIC

Extracted from openapi.ro, business APIs for Romanian developers.
Includes ActiveModel validators.

Installation

Include it in your Gemfile. If you just want the validation, without ActiveModel, use:

gem 'romanianvalidators'

If you want ActiveModel integration, use instead:

gem 'romanianvalidators', require: 'romanian_validators/active_model'

Has no other dependency (other than ActiveModel if you require it).

Tested with MRI 1.9.3, 2.0, 2.1, 2.3, REE, Rubinius and JRuby (see .travis.yml)

Usage

Without ActiveModel, just call the valid? method on the corresponding module

    > RomanianValidators::Cif.valid?(13548146)
    => true
    > RomanianValidators::Iban.valid?(123)
    => false

With ActiveModel, include it in your model

    include RomanianValidators::ActiveModel::Validations

then use like this:

    validates :my_attribute, cif: true

Example:

    class User
      include ActiveModel::Model
      include RomanianValidators::ActiveModel::Validations
      attr_accessor :cnp, :company_cif
      validates :cnp, cnp: { message: 'This is not a valid CNP' }
      validates :company_cif, cif: true
    end
    > u = User.new(cnp: 123, company_cif: 123)
    => #<User:0x007fbf7f959b38 @cnp=123, @company_cif=123>
    > u.valid?
    => false
    > u.errors
    => #<ActiveModel::Errors:0x007fbf80958548 @base=#<User:0x007fbf7f959b38 @cnp=123, @company_cif=123, @validation_context=nil, @errors=#<ActiveModel::Errors:0x007fbf80958548 ...>>, @messages={:cnp=>["This is not a valid CNP"], :company_cif=>["is invalid"]}, @details={:cnp=>[{:error=>"This is not a valid CNP"}], :company_cif=>[{:error=>:invalid}]}>

For CIFs, a (lazy) enumerator is provided. This enumerator is significantly
more efficient than iterating over a range of numbers and filtering valid CIFs, because
it generates the control digit from cif % 10 directly.

Example:

> RomanianValidators::Cif.enumerator(1).take(10).to_a
=> [19, 27, 35, 43, 51, 60, 78, 86, 94, 108]
> RomanianValidators::Cif.enumerator(1_000_000, :down).take(10).to_a
=> [999993, 999985, 999977, 999969, 999950, 999942, 999934, 999926, 999918, 999900]

Upgrading

If upgrading from 0.1.x, note that the ActiveModel validations are now in a separate module so you need to add
include RomanianValidators::Validations in your models. Additionaly you need to add a require in your Gemfile (again, only if using ActiveModel):

  gem 'romanianvalidators', require: 'romanianvalidators/active_model'

Changelog

0.2.0

moved validations from ActiveModel::Validations to RomanianValidators::Validations.
This module must be manually required in models.
added a lazy enumerator that generates valid CIFs: RomanianValidators::Cif.enumerator(start, direction = :up)
