Rails 3 and 4 Bank Routing Number validator

This gem is intended to be a minimal application of validations provided in larger libraries (see ActiveMerchant) if a more minimal implementation is intended.

Use this gem as if it was just another ActiveModel validator (because it is)

class MyModel < ActiveRecord
  validates :my_routing_number, :routing_number => true
end

billing_info = MyModel.new(invalid_routing_number_params)
billing_info.valid? => false

Add this line to your application's Gemfile:

gem 'routing_number_validator'

then run:

$ bundle

Then add the following to your model:

validates :my_routing_number, :routing_number => true
