Elfproef

• Validate international IBAN account numbers
• Validate Dutch BSN (Social Security) numbers (8 or 9 digits)
• Validates Dutch bank account numbers (9 or 10 digits)
• Allow for 1-7 digit ING bank account numbers
• Validate Dutch payment reference numbers (betalingskenmerken)

Install as a gem

gem install elfproef

Or add it to your gemfile

gem 'elfproef'

and run

bundle install

As of elfproef-0.2.0 you need ruby-1.9.3 or up, ruby-2.0.0 is preferred.

If your project is stuck at <= ruby-1.9.2, use the latest elfproef-0.1.x release.

gem 'elfproef', '0.1.4'

Using the BsnValidator:

class User < ActiveRecord::Base
  validates :bsn_number, bsn: true
end

Using the BankAccountValidator:

class User < ActiveRecord::Base
  validates :account_number, bank_account: true
end

Using the PaymentReferenceValidator:

class User < ActiveRecord::Base
  validates :reference, payment_reference: true
end

You can also use these validators without ActiveRecord by including ActiveModel::Validations:

class AwesomeDutchPerson
  include ActiveModel::Validations
  validates :bsn, bsn: true
end

Add the following to your locale file:

en:
  activemodel:
    errors:
      models:
        YOUR_MODEL:
          attributes:
            ATTRIBUTE:
              invalid_bank_account: "is not a valid bank account number"
              invalid_bsn: "is not a valid BSN"
              invalid_payment_reference: "is not a valid payment reference"

Please post them to Github Issues.
