Orderitem_set.all() возвращает пустой запрос

def cart(request, *args, **kwargs):

    if request.user.is_authenticated:
        customer = request.user.customer
        order, created = Order.objects.get_or_create(customer=customer,complete=False)
        items = order.orderitem_set.all()
        print(items)
    else:
        items = []
    
    return render(request, 'product_pages/cart.html', {'items': items})

все хорошо до значения этого элемента, потому что элементы возвращают пустой запрос. И это сообщение возвращается в терминал.
