I have a model:

class MyModel(models.Model):
    name = [...]
    surname = [...]
    symbol = models.CharField(unique=True)
    [...]

And I want to automatic generate some data in symbol field when user click “new” in admin panel. For example:

def generate_symbol():
    last_symbol = MyModel.objects.all().order_by('symbol')[0]
    return "%d" % (last_symbol + 1)

How to do it?

    Override ModelAdmin.get_form(), and use a dynamic initial value.
