html response before saving object

Hi Guys, 

I've update my site from django 1.3 to 1.5

The site works fine, except for a view, the template renders before the obj.save() in the view:

def cart(request):

    try:

        cart = Cart.objects.prefetch_related('cartitem_set__product__category').get(id=request.session['cart_id'])

    except (KeyError, Cart.DoesNotExist) as e:

        cart = Cart()

        cart.save()

        request.session['cart_id'] = cart.id

    if 'add' in request.GET:

        try:

            product = Product.objects.get(slug=request.GET['add'], active=True)

            cart_item = CartItem.objects.get(product=product, cart=cart)

        except CartItem.DoesNotExist:

            cart_item = CartItem(product=product, cart=cart)

            cart_item.save()

        except Product.DoesNotExist:

            pass

    response_args = {'cart': cart}

    return render_to_response('products/cart.html', response_args, context_instance=RequestContext(request))

I don't know why this happens

any help? something has changed? now the database save is async?
