Valabn

Valabn (read valaban) is a simple Australian Business Number (ABN) validator.

Installation

Add this line to your application's Gemfile:

gem 'valabn'

And then execute:

$ bundle

Or install it yourself as:

$ gem install valabn

Usage

If you just need to check the format of the ABN, just use:

Valabn::Utils.validate_format(number) #=> Boolean

In order to lookup real ABN, you'll need to get a GUID (https://abr.business.gov.au/RegisterAgreement.aspx). Once you've got one initialize the gem like this:

require 'valabn'

Valabn::Lookup.configure do |config|
  config.guid = APP_GUID # Your assigned GUID
  config.cache_host = 'localhost' # (optional) The host of the redis server
  config.cache_port = '6379' # (optional) The port of the redis server
end

cache_host and cache_port are optional configuration attributes in order to keep a cache on a redis database. The current cache configuration lives up to two hours.

After that, you invoke

Valabn::Lookup.validate(abn) #=> Hash

number = Valabn.new(abn)
number.exists? #=> Boolean
number.exists?(details: true) #=> Hash or false

TODO:

  • Allow custom expiration time on the cache.
  • Integrate with Activerecord/ActiveModel as validator.
  • Add specs

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
