Where can I find materials on the Django ORM?

Question

Django

Hello.
And do not tell me where you can find material on the work of ORM Django and PostgreSQL? Interested in optimizing queries to the database through the Django ORM and the features of the Django and PostgreSQL ORM.
However, the Django documentation doesn't have much to say about this. Have more detailed information?

Answer 1

However, the Django documentation doesn't have much to say about this.

Are you sure you read the documentation?
Here:
https://docs.djangoproject.com/en/1.10/ref/models/...
https://docs.djangoproject.com/en/1.10/topics/db/o...
https://docs .djangoproject.com/es/1.10/ref/models/...
https://docs.djangoproject.com/es/1.10/ref/models/...
written as much as you will not find anywhere else.

Answer 2

https://docs.djangoproject.com/en/1.10/ref/contrib...
But Django doesn't seem to be able to do specific indexes.
