Here’s the canonical way to use a ModelForm to create or update a model instance:
def myview(request, pk=None):
if pk:
instance = get_object_or_404(Subscriber, pk=pk)
else:
instance = None
if request.method == "POST":
form = SubscriberForm(request.POST, instance=instance)
if form.is_valid():
instance = form.save()
# do whatever with instance or just ignore it
return redirect(some return url)
else:
form = SubscriberForm(instance=instance)
context = {"form":form}
return render(request, "path/to/your/template.html", context)
If your view doesn’t look something like it then you’re very probably doing it wrong. Your mention of a tshirt_size = request.POST.get('tshirt_size')
in your view is a sure smell you’re doing it wrong FWIW.
