I wouldn’t use a model. You can store the values directly in the session. Considering that you can store everything in the session you can store the items in a dictionary do something like.
def view_cart(request):
cart = request.session.get('cart', {})
# rest of the view
def add_to_cart(request, item_id, quantity):
cart = request.session.get('cart', {})
cart[item_id] = quantity
request.session['cart'] = cart
# rest of the view
