Re: Changing the primary key of Django models

[Dheerendra Rathor]

Yes you can keep custom primary key. Pass `primary_key=True` in your model
and Django won't create a primary key for that model.

Here are relevant docs:
https://docs.djangoproject.com/en/1.9/ref/models/fields/#django.db.models.Field.primary_key
