I'd like to set some attributes to some default values before the
model is created. Here's what I have so far:
slots_available = models.IntegerField(blank=True)
position = models.IntegerField(blank=True)
def save(self):
if slots_availalbe == None:
slots_available =
StorageUnitType.objects.get(pk=parent).total_slots
if position == None:
position = 1
super(StorageUnit, self).save()
Is this the best way of doing this? Is there a way I can specify that
this code should run only when a model is first saved? I read
something about using listeners for some post and pre save signals,
but wasn't able to find any documentation on it.
TIA
