class SoftDeleteManager(models.Manager):
    def get_queryset(self):
        return super().get_queryset().filter(deleted_at__isnull=True)


class SoftDeleteModel(models.Model):
    deleted_at = models.DateTimeField(null=True, blank=True, db_index=True)

    objects = SoftDeleteManager()
    all_objects = models.Manager()  # Access all including deleted

        super().delete()

    def restore(self):
        self.deleted_at = None
