Updating prod postgresql db with Flask Heroku

Question

I have ran the following command in my dev db:

flask db migrate -m "updated the schema" 
flask db upgrade

Which successfully did the migration and updated the schema. However, when I pushed the commit to heroku the prod schema didn't change. How can I do the same update in heroku prod postgresql?

I tried switching my profile code from:

web: gunicorn run:app --log-file=- 

to:

web: flask db upgrade; gunicorn run:app --log-file=- 

& even adding:

heroku config:set FLASK_APP=run.py

for restarting. However, the prod db schema remains unchanged.

Answer 1

The following commands did the job:

Heroku run bash
flask db migrate
flask db upgrade
