Hi Mario,
Thanks so much - I updated my view as below and it is now working as
expected!
Regards,
Leslie
if form.is_valid():
new_item = form.save(commit=False)
new_item.client = orderClient
new_item.orderdate = datetime.now()
new_item.orderIP = remote_ip
new_item.status = "Not_Paid"
new_item.save()
form.save_m2m()
ordernumber = new_item.pk
for opt in request.POST.getlist('srvoptions'):
theopt = srvoptions.objects.get(pk=opt)
new_item.srvopts.add(theopt.id)
