Derek,
I tried that and now I get the following error:
AttributeError at /rugs/cart/1/4/
'Choice' object has no attribute 'value'
/////////////
Here is my view
def showcart(request, style_id, choice_id):
s = Style.objects.get(id=style_id)
c = Choice.objects.get(id=choice_id)
#x = c.size, " ", c.price
cart = request.session.get('cart', [])
cart.append({'style': s, 'choice': c})
request.session['cart'] = cart
pr = 0
for a in cart:
pr = pr + a['choice'].value
return render_to_response('show_test.html', {'mychoice': cart, 'p':
pr})
/////////
