Container Number Validator

This gem allows you to easily validate container number fields to be valid container numbers.

It validates Container Number according to ISO_6346

NYKU5824120

Also supports format where checkdigit is seperated with a dash like this

NYKU582412-0

Add this line to your application's Gemfile:

gem 'container_number_validator'

And then execute:

$ bundle

Or install it yourself as:

$ gem install container_number_validator

ContainerNumberValidator.validate('NYKU582412-0')
#=> true

ContainerNumberValidator.validate('NYKU582412-3')
#=> false

You can use ContainerNumberValidator with any ActiveModel class, including ActiveRecord models:

class Container < ActiveRecord::Base
  validates :container_no, container_number: true
end

• When no container number is present (or set to nil), all container numbers are considered INVALID.

• Make 10 checksum result configurable
