hi Daniel
cool, thanks
in combination, now it looks like this:
class MyModel(models.Model):
created = models.DateTimeField()
modified = models.DateTimeField()
parent = models.ForeignKey('self', related_name='children', null=True,
blank=True)
def save(self, **kwargs):
now = datetime.now()
self.modified = now
if not self.id:
self.created = now
if self.parent:
self.parent.save(**kwargs)
super(MyModel, self).save(**kwargs)
cheers
André
