validates_iban_format_of

Rails IBAN validator based on iban-tools gem

Installation

Add it to your Gemfile:

gem 'validates_iban_format_of'

Usage

In ActiveRecord model

# I18n locales are loaded automatically.

class BankAccount < ActiveRecord::Base
  validates_iban_format_of :iban, message_for_invalid: 'is not incorrect', message_for_missing: 'is blank'

  # OR
  # validates :iban, iban_format: { message_for_invalid: 'is not incorrect', message_for_missing: 'is blank' }
end

In your model spec using RSpec:

require "validates_iban_format_of/rspec_matcher"

describe Person do
  it { should validate_iban_format_of(:iban).with_message('is not looking good') }
end

Options

:message_for_invalid
   String. A custom error message when the iban is invalid (default is: "is invalid")

:message_for_missing
   String. A custom error message when the iban is missing (default is: "is missing")

:optional
   Boolean. Flag to turn off valdiation for blank/nil case

:generate_message
  Boolean. Return the I18n key of the error message instead of the error message itself (default is false)
