I think the best way is to override the Model's save method:
class Structure(models.Model):
parent
= models.ForeignKey('site.Structure',blank=True,null=True,default=0)
title = models.CharField(max_length=128,verbose_name=u'Заголовок')
url = models.CharField(max_length=48,verbose_name=u'URL')
ordering = models.IntegerField(blank=True,editable=False,default=1)
level = models.SmallIntegerField(blank=True,editable=False,default=1)
def save(self, *args, **kwargs):
if not self.id:
# If the primary key is not defined, this is a new insertion
self.ordering = 42 # set magic values
self.level = 99
super(Structure, self).save(*args, **args)
