== ActiveCart

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.

== Installation gem install active_cart

== Usage

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.

For information about the API and interfase, checkout the documentation: http://rdoc.info/projects/madpilot/active_cart

== 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[0] => #<ActiveCart::Items::MemoryItem:0xb7a63170 @price=10, @name="Test Item", @quantity=2, @id=1> c.total => 20
