Hi all,
I have a class with a many2many field:
class Previsione(models.Model):
nave = models.CharField(maxlength=50)
data_manovra = models.DateField()
h_inizio = models.TimeField()
rims = models.ManyToManyField(Rim)
into the views.py I use this code to save the submitted data:
....
if req.method == 'POST':
myform = nf.models.form_for_model(Previsione)(req.POST)
if myform.is_valid():
dati = myform.save(commit=False)
if varid is not None:
dati.id=varid
dati.save()
dati.rims = req.POST.getlist('rims')
return HttpResponseRedirect('.')
else:
....
but when I update the data the old rims are deleted and the new inserted ... is
possible to UPDATE the rims data ? cioe', is possible to leave unchanged the
rims data if are the same ?
tanks in advance ...
