Re: set model field some value before add

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)

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)

I'd like to set Structure.ordering and Structure.level with special
values, based on something.

Is there way to provide Structure.before_add(self) method? I need this
method to be called every time after saving model data.
