What does it mean through your application only? As opposed to changed with direct access to the database?

If that is the case then it is trivial - do not distribute the database password to anyone. If you need to give access to other applications create separate users/roles for such purpose.

As for django - it provides another layer of security, as described here and you can extend it if it does not fit your bill.
