SQLite Database not connected in Django Heroku - django

Question

So i was trying to deploy my project to Heroku and i followed this steps : https://www.codementor.io/#jamesezechukwu/how-to-deploy-django-app-on-heroku-dtsee04d4
. The build was successfull and i was able to run the server : https://pcbuildingparts.herokuapp.com/
but the database doesn't seem to connect beacause the items from database doesn't show at all and i tried to login in my admin site with my superuser account before deploying, but it doesn't let me in.
This is my settings.py

Answer 1

Is there a specific reason as to why you want to use SQLite on Heroku? A great option would be to use the postgress addon and use SQLite for local development and testing.
See how to connect to postgres in Django: postgres
You can also use the django-heroku package to easily configure your django app.
