Install as a gem
gem install elfproef
Or add it to your gemfile
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
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"
