Re: [Webware-discuss] Shopping Cart App

[Aaron Held]

An easy way is to make the cart a list. def AddItem(item)     cart = self.session().value('cart',[])     cart.append(item)     self.session.setValue('cart',cart) def DelItem(item)     cart = self.session().value('cart',[])     try:           cart.remove(item)     except   ValueError:        print "Item Removed"     self.session.setValue('cart',cart) A better implementation would be an external module where you would pass in a user or session object and get back a cart object.

I’m working on the prototype of an online catalog (just presentation, no order processing) implemented in Webware. We’re at the point where we would like to let visitors select products and later review their list, but I’m at a loss as to how to persist that information. (Naivety on my part regarding web apps.)   Any leads would be appreciated.     Tom Dennehy Bloomfield Hills MI USA   -- -Aaron http://www.MetroNY.com/ "I don't know what's wrong with my television set.
