This is a Spree extension that wraps the popular active_shipping plugin.

To install this extension, place these two lines inside your application's Gemfile:

gem 'active_shipping', :git => "git://github.com/Shopify/active_shipping"
gem 'spree_active_shipping', :git => "git://github.com/spree/spree_active_shipping"

You will need a UPS developer account to get rate quotes (even in development and test mode.) The UPS calculators also require that you set the following configuration properties. You will also need a USPS account to use USPS rate quote system. Note: acquiring the USPS developer account is easy but has a confusion activation step. Look for related sicussion in ActiveShipping's original discussion group as well as carefully read your USPS confirmation email.

Spree::ActiveShipping::Config[:origin_country]
Spree::ActiveShipping::Config[:origin_city]
Spree::ActiveShipping::Config[:origin_state]
Spree::ActiveShipping::Config[:origin_zip]
Spree::ActiveShipping::Config[:ups_login]
Spree::ActiveShipping::Config[:ups_password]
Spree::ActiveShipping::Config[:ups_key]
Spree::ActiveShipping::Config[:usps_login]

It will soon be possible to set these properties through a new admin configuration screen (even sooner if someone else writes the patch!)

Spree::ActiveShipping::Config[:handling_fee]

This property allows you to set a global handling fee that will be added to all calculated shipping rates. Specify the number of cents, not dollars.

For products lacking defined weights, there is a fallback value you're invited to set:

Spree::ActiveShipping::Config[:default_weight]

If you'd like to set your shipping configuration as part of a migration you could add something like this to your site extension.

class AddUpsConfiguration < ActiveRecord::Migration
  def self.up
    Spree::ActiveShipping::Config.set(:ups_login => "dpbrowning")
    Spree::ActiveShipping::Config.set(:ups_password => "doublewide")
    Spree::ActiveShipping::Config.set(:ups_key => "5B8DDE509EFDA5D6")
    Spree::ActiveShipping::Config.set(:usps_login => "13658997AOE2568XOE")
  end

  def self.down
  end
end

gem 'spree_active_shipping'

#only required until gem 0.9.13 is released
