ok ... first of all TANKS for the help and for the very clear explanation
;-)))
I've resolved (more clear and more coincise !!) with:
*******
def previsione(req, varid=None):
if req.method == 'POST':
myform = nf.models.form_for_model(Prev)(req.POST)
if myform.is_valid():
if varid is not None:
instance = get_object_or_404(Prev, pk=varid)
newforms.models.save_instance(myform, instance)
else:
myform.save()
clean_path=re.sub('/[0-9]+/','',req.path)
return HttpResponseRedirect(clean_path)
else:
....
********
the last thing is that the m2m data are ALWAYS updated with an increment of
the 'id', even if data are unchanged ... but I think I've to "play"
(eventually ;-))) with the 'save()' method ...
tanks again .... my turn next time ... I hope ;-)))
bye ....
