The example code you provided will create a on the first iteration of
the loop and tag every 4th iteration of the loop. This cycle will
continue resulting in a table with 4 columns of data. Example:
results = [ 1, 2, 3, 4, 5, 6, 7, 8 ]

I feel you, figuring out such errors for the first time can be infinitely
frustrating.
I believe that the form is sending you product id numbers as strings, or 1 as
‘1’.
If the product_id = ‘1’ then product_id is not None.
However, you have defined product_id in the model for Product as an in

Sweet, looks like your code is working!
You’re still seeing the ‘2’ and that the type of product_id is a string because

def update(request):
product_id = request.POST.get("product_id")
if product_id is not None :
print(product_id)
product_id = int(product_id)

cart_obj, new_obj = Cart.objects.get(user=request.user)

cart_obj.products.remove(product_obj)
added = False

cart_obj, new_obj = Cart.objects.new_or_get(request)
There is no .new_or_get method in the Django QuerySet API:
