validates_as_vat_number

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.

Install

Specify it in your Rails config.

config.gem 'validates_as_vat_number', :source => 'http://gemcutter.org'

Then install it.

rake gems:install

Example

class Company < ActiveRecord::Base
	validates_as_vat_number :vat
end

Acknowledgements

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.
