Now you can validate VAT using the European service called VIES, to ensure it exists. Only require this gem and call validate_as_vat_number on your VAT field, in an Active Record object.
Specify it in your Rails config.
config.gem 'validates_as_vat_number', :source => 'http://gemcutter.org'
Then install it.
class Company < ActiveRecord::Base validates_as_vat_number :vat end
Thanks to sborsje for fixing the instance with valid ISO 3660 but unsupported codes.
Note on Patches/Pull Requests
- Fork the project.
- Make your feature addition or bug fix.
- Add tests for it. This is important so I don't break it in a future version unintentionally.
- Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
- Send me a pull request. Bonus points for topic branches.
