This gem provides basic postcode validation functionality which can be used in any application

The specific validation that we perform goes beyond simple regex matching, to determine if the postcode actually exists.

To do this it uses PCAPredict.com's Capture+ API. By leveraging this service we are able to provide validation against country's postcode that they support.

It also comes with out of the box plugins for:

• Solidus

Add this line to your application's Gemfile:

gem 'postcode_validation'

And then execute:

$ bundle

Or install it yourself as:

$ gem install postcode_validation

This gem relies on ENV['POSTCODE_ANYWHERE_KEY'] being set to a valid PCAPredict service key for Capture+.

One of the easiest ways to do this is to use the dotenv gem for this in your host application.

require 'postcode_validation'
require 'postcode_validation/plugins/solidus'
Spree::Order.include(PostcodeValidation::SpreeOrderPostcodeValid)

NB: Error reporting currently only works with a Tagged Logger

require 'postcode_validation'
use_case = PostcodeValidation::UseCase::ValidateAddress.new(
  address_match_gateway: PostcodeValidation::Gateway::PCAPotentialAddressMatch.new
)

valid = use_case.execute(postcode: 'SE10SW', country: 'GB')[:valid?]

> valid
true

Country must be a valid 2-letter ISO country code. Postcode is the postcode under test.

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.
