ActiveCart is a Shopping Cart framework, it's not a fullyfledged cart, so you will need to do some stuff to get it to work.
The cart system has a storage engine, which means you aren't bound to a particular database. So far, there is a an ActiveModel storage engine, called acts_as_cart, but the gem isn't just for Rails, by writing other engines, you could target any datastore.
gem install active_cart
require 'rubygems' require 'active_cart' @cart = ActiveCart::Cart.setup(MyStorageEngine.new) do |t| t << ShippingOrderTotal.new t << GstOrderTotal.new end
In this example the ShippingOrderTotal and GstOrderTotal have been created by the developer and follow the OrderTotal interface.
