what do you mean with "saving a web form" ?? saving the form and NOT
the save method on instance ??
I use :
***
myform = nf.models.form_for_model(Previsione)(req.POST)
if myform.is_valid():
dati = myform.save(commit=False)
***
to change eventually the 'id' value for the insert/update
***
if varid is not None:
dati.id=varid
***

I create a web form to insert/update the Previsione data ... my urls.py:
urlpatterns = patterns('modulistica.savona.views',
(r'^index/$', 'index'),
(r'^Previsione/$', 'previsione'),
(r'^Previsione/(?P<varid>\d+)/$', 'previsione'),
)
when I get the 'Previsione/' URL I go to insert the data ... when I get
the 'Previsione/10/' URL I go to update the data of the Previsione(pk=10).
****************************
the previsione function :
def previsione(req, varid=None):
if req.method == 'POST':
myform = nf.models.form_for_model(Previsione)(req.POST)
if myform.is_valid():
dati = myform.save(commit=False)
salva_rims = True
list_rims = req.POST.getlist('rims')
if varid is not None:
dati.id=varid
clean_path=re.sub('/[0-9]+/','',req.path)
else:
clean_path = req.path
# controlla se ci sono stati cambiamenti
# nel campo m2m
#
old_rims=list(dati.rims.all())
new_rims=Rim.objects.in_bulk(list_rims).values()
old_rims.sort()
new_rims.sort()
if old_rims == new_rims:
salva_rims = False
dati.save()
if salva_rims == True:
dati.rims = list_rims
return HttpResponseRedirect(clean_path)
else:
# method GET
#
if varid is None:
myform = nf.models.form_for_model(Previsione)()
else:
instance = get_object_or_404(Previsione, pk=varid)
myform = nf.models.form_for_instance(instance)()
return render_to_response('create_form.html', \
{ 'titolo': 'Archivio Previsioni',
'form': myform.as_table() })
tanks for the help ;-))) and sorry for my english !!
