Q: Python Django Docker - Unknown server host 'db' error when trying to make a super user

I am trying to use the command python manage.py createsuperuser and docker exec -it veganetwork-db-1 python manage.py createsuperuser to add myself as a superuser to my microservices project, however when I try to run both of these commands I get Unknown server host 'db' in my Windows Powershell, here is the entire error:

django.db.utils.OperationalError: (2005, "Unknown server host 'db' (11001)")
I have tried some other methods in some other posts like creating a class named Command in my manage.py script to create the superuser: Create django super user in a docker container without inputting password, using docker-compose run django python manage.py createsuperuser rather than the regular docker command which is docker exec -it veganetwork-db-1 python manage.py createsuperuser: https://github.com/vchaptsev/cookiecutter-django-vue/issues/25, and finally trying to change the depends_on variable inside my docker-compose.yml file and restarting the docker container itself: django.db.utils.OperationalError: (2005, "Unknown MySQL server host 'db' (-2)"). I have tried all of these solutions but they have all failed.
here is my docker-compose file as well as my dockerfile:

What exactly am I doing wrong here, thank you!

django.db.utils.DatabaseError with Django and Djongo

I keep running into the django.db.utils.DatabaseError error with trying to migrate the database changes in a Django project.

I am stumped on how to solve this issue. I have tried sqlparse==0.2.4 as suggested here but it did not work for me.
Deleted everything in the migrations folder and started from scratch. The same error pops up but now it is even longer.
I understand there is a not implemented error but not sure how to fix it.
The models.py:
from djongo import models
class User(models.Model):
age = models.FloatField()
height = models.FloatField()
waist = models.FloatField()
weight = models.FloatField()
