Couldn't find WSGI module deploying Heroku

Question

Trying to deploy my app with this tutorial. Have a ModuleNotFoundError: No module named 'radio.wsgi' message.

2019-08-21T08:08:21.409841+00:00 app[web.1]: __import__(module)
2019-08-21T08:08:21.409849+00:00 app[web.1]: ModuleNotFoundError: No module named 'radio.wsgi'
2019-08-21T08:08:21.409960+00:00 app[web.1]: [2019-08-21 08:08:21 +0000] [10] [INFO] Worker exiting (pid: 10)
2019-08-21T08:08:21.441211+00:00 app[web.1]: [2019-08-21 08:08:21 +0000] [4] [INFO] Shutting down: Master

In some other questions people recomends python manage.py run_gunicorn but I have Unknown command: 'run_gunicorn'

Procfile:

web: gunicorn radio.wsgi --log-file -

wsgi.py

import os
from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'radio.settings')
application = get_wsgi_application()

In only those files WSGI is mentioned.

How about mv Procfile radio/? – Vershen

If you look at the tutorial source code, you'll see that Procfile, runtime.txt and requirements.txt are all at the same level as manage.py which is the root of your project repository. – Jollify

@WaketZheng, nope. "No web processes running" – Straley

@dirkgroten, how can I restruct project like this? Цhen I initialized the player application it automatically placed here – Straley

What is "when I initialised the player application"? requirements.txt, runtime.txt, README.md... are all files you added manually in the wrong directory. Just move all these files inside your top radio directory. Actually, you probably did it wrong when initialising your git repository. radio should be the repository not the directory containing radio. – Jollify

On Heroku, the Procfile must be in the project root. You could move the contents of radio into the root directory (e.g. so manage.py is alongside Procfile), or you can add the radio directory to the Python Path. – Iden

@WaketZheng moving Procfile won't work, because Procfile must be in the project root. – Iden

Answer 1

Heroku expects Procfile to be in the project root. It is easiest to deploy a Django app if manage.py is in the project root as well. For example, if your project layout was:

├── db.sqlite3
├── manage.py
├── player
├── radio
│   ├── __init__.py
│   ├── __pycache__
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
├── setup.py
├── static
├── README.md
├── .gitignore
├── requirements.txt
├── runtime.txt
└── Procfile

then you can run:

web: gunicorn radio.wsgi

In your case, your Django project is in the radio directoy. If you don't want to change the project layout, then you need to add radio to the python path so that python imports work:

web: gunicorn --pythonpath radio radio.wsgi

Answer 2

After login from terminal using heroku login by downloading Heroku CLI, you can deploy on heroku using git by following:

git init
git add .
heroku create <app_name> --region <region_name>
git commit -am "SOME MESSAGE"
heroku config:set DEBUG_COLLECTSTATIC=1
heroku ps:scale web=1    // (optional)
git push heroku master

The ideal project structure shuold be like this...

   radio
   ├── db.sqlite3
   ├── manage.py
   ├── player
   ├── radio
   │   ├── __init__.py
   │   ├── settings.py
   │   ├── urls.py
   │   └── wsgi.py
   ├── setup.py
   ├── static
   ├── README.md
   ├── requirements.txt
   ├── runtime.txt
   └── Procfile
