Why would django fail with server 500 only when Debug=False AND db is set to production database on Heroku?

Question

When we run $ python manage.py runserver --settings=project.settings.local there are 4 different possible combinations:

1. Debug=True && DB=l

Answer 1

What you should be doing here is this:

• Open up your Heroku logs by running $ heroku logs --tail in one terminal window.
• In another terminal window run $ heroku ps:restart to restart your dynos.

Watch the logs, and see the actual traceback. This will tell you exactly what's going on. Based on your configuration it could be a number of issues.
