I've done some more testing with these two functions. It seems that
when the function 'deletecart' is accessed the line 'del
request.seesion['cart'][0]' is working. It's deleting the first
element in request.session['cart']. Because I get directly returned
to my showcart function and the first element is gone. However, it's
gone only temporarily. When I try to delete the first element again
nothing happens. For some reason the first element that I deleted
first is somehow still there behind the scenes. When I go to a new
page and then back to showcart the first element that i thought I
deleted is still there.
Here are my views
def showcart(request, style_id, choice_id):
s = Style.objects.get(id=style_id)
c = Choice.objects.get(id=choice_id)
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'].price.name
return render_to_response('show_test.html', {'mychoice': cart, 'p':
pr})
def deletecart(request):
del request.session['cart'][0]
pr = 1000
return render_to_response('show_test.html', {'mychoice':
request.session['cart'], 'p': pr})
////////////////////////
If I move the line 'del request.session['cart'][0] up into my showcart
function right after 'request.session['cart'] = cart' then it works
fine. However, I don't want to add a product to the cart and then
delete the first item in the cart. It's just weird how that line 'del
request.session['cart'][0]' works fine in the showcart function but
doesn't work right in the deletecart function.
Thanks for any help.
