Django Heroku no module named 'my app name'

问题

I'm trying to deploy my first Django app to Heroku. I was able to migrate the database and create a superuser, but now I'm stuck on this:

I developed my application using some tutorials that use mysite in my settings. But now my Heroku app is named whispering-shelf-25150.

What is the relation between those names? For example, should I change every occurence of mysite in settings.py to whispering-shelf-25150?

In my wsgi file I have:

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "whispering-shelf-25150.settings.settings")

The name of your Heroku app is irrelevant. There is no relationship between it and your Python module names.

The name of your settings module must match what's in your project folder, and the name of the top-level folder doesn't matter.

For example, if your directory tree looks like

• project/ ← ignore this
  • mysite/ ← include this
    • settings.py ← include this
  • some_app/
    • ...

your settings module is mysite.settings.

Use this guide it always works, plus there's some unique approach to deploying to heroku. https://www.codingforentrepreneurs.com/blog/go-live-with-django-project-and-heroku/
