They determine the next value by calling a function called number(). In your case it would look something like this:

class Cliente(models.Model):

    """This is the client data model, it holds all client information. This

       docstring has to be improved."""

    def number():

        no = Cliente.objects.all().aggregate(Max(order))

        if no == None:

            return 1

        else:

            return no + 1

    clientcode = models.IntegerField(_('Code'), max_length=6, unique=True, \

    default=number)
