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.

Sample using the contrived Memory demo classes in irb
>> require 'rubygems' => true >> require 'active_cart' => true >> include ActiveCart => Object >> c = Cart.new(ActiveCart::StorageEngines::Memory.new) => #<ActiveCart::Cart:0xb7a697a0 @order_total_calculators=, @storage_engine=> >> c.add_to_cart(ActiveCart::Items::MemoryItem.new(1, "Test Item", 10)) => nil >> c.add_to_cart(ActiveCart::Items::MemoryItem.new(1, "Test Item", 10)) => nil >> c => #<ActiveCart::Items::MemoryItem:0xb7a63170 @price=10, @name="Test Item", @quantity=2, @id=1> >> c.total => 20
