Add db_index on the added_on model field to improve sorting/filtering and make a migration.

class BaseModel(models.Model):
        id = models.BigAutoField(primary_key=True, db_index=True)

        added_on = models.DateTimeField()

        def __str__(self):
            return str(self.id)

        class Meta:
            abstract = True
            ordering = ('-added_on',)

Hello @tsantor,

The decision to add indexes is left to the developer's discretion. Some may choose to include partitioning or multi-column indexes. Please feel free to add indexes manually based on your specific requirements.
