heroku postgres psycopg2.errors.UndefinedTable

Would anyone have any tips for deploying heroku django app with the hobby free postgres version that heroku provides? This error below in the traceback almost seems similar when I was testing locally if I didnt do a python manage.py migrate in the django build process.

Also new to django, heroku, and postgress to so tips greatly help. These are my steps using the heroku pipeline to deploy:

git push heroku master
heroku ps:scale web=1
heroku open

This is the trace back through heroku logs when I try to view the webpage:

UPDATE, as mentioned beautifully in the first comment, did you do the tutorial? I missed this when deploying to heroku the database section heroku run python manage.py migrate. Do the whole tutorial make sure it runs locally prior !
