requirements:

Django==3.0.5
djangorestframework==3.12.2
djongo==1.3.3
pymongo==3.11.2

Answer 1

Maybe you can share some more code and help out with providing what you already have.

A few things which can already be checked:

1. Did you install al the requirements?

pip install -r requirements.txt [OR]
pip install Django==3.0.5 djangorestframework==3.12.2 djongo==1.3.3 pymongo==3.11.2

2. Did you import the neccesary modules?

from djongo import DjongoManager

This may not include all necesarry imports. Check the documentation or post the code that you already have.

3. Check the super part. It looks like the script doesn't know what to do with getattr. Maybe there is a typo in your super part or you didn't program it to handle it.
