Django: child models with the same properties, but different attributes on those properties

I have two models in my database that, if I don't do anything "creative" will look something like this:

class AbstractModel(models.Model):

    uuid = models.UUIDField(default=uuid.uuid4)

    class Meta:
        abstract = True


class ModelA(AbstractModel):
    name = models.CharField(max_length=128)


class ModelB(AbstractModel):
    name = models.CharField(max_length=128, blank=True, null=True)

The only real difference between ModelA and ModelB is that I want ModelA's name property to be non-nullable, but writing it like this, especially when you consider that I've got about 10 different fields to write in much the same situation, feels very not-DRY. Surely, there's a better/smarter way?

Note that this isn't about validation, so moving the blank-checking up into a form isn't going to solve the problem. I want the database column to be NOT NULL for ModelA and NULL for ModelB.
