This extension provides Zones based on ZIP code ranges to the Spree e-Commerce framework. It was written for Spree 0.10.2, but might work with other versions as well.
To install, first grab the extension using Git:
script/extension install git://github.com/wapcaplet/spree-zip-code-zone.git
Then migrate your database to add the necessary tables:
rake db:migrate
ZIP code ranges can be edited from the Administration / Configuration interface; then a Zone may be defined with one or more ZIP code ranges as members.
Once you've defined your zones, you can configure them for taxation or shipping like you would with a state- or country-based zone.
This extension creates one new model, ZipCodeRange, which stores a starting
and ending ZIP code. The design of this model is based on the State model,
with slight changes to the comparison and to_s methods.
There is an Admin::ZipCodeRangesController that thinly wraps the administrative
views for creating, updating, and/or deleting ZIP code ranges.
The zip_code_zone_extension.rb contains overrides to the Zone and
Admin::ZonesController classes in order to support the ZipCodeRange model
as a zoneable type. Two admin/zones view partials are also overridden, as is the
public/javascripts/zone.js script responsible for showing and hiding the zonable
fields.
