Django website deploying to heroku. Application error

Question

I'm trying to deploy my django website to heroku but I get an Application Error shown on the webpage. Looking at my logs using heroku logs --tail (what it tells me to do on webpage), I recieve an error

2019-07-27T06:14:34.046386+00:00 heroku[router]: at=error code=H14 desc="No web processes running" method=GET path="/" host=prremia.herokuapp.com request_id=20cd473d-50c2-43b6-892e-ce8f8981229d fwd="49.36.8.33" dyno= connect= service= status=503 bytes= protocol=https

I followed the instructions from Django's docs.

Django 2.2.3
Python 3.7.3
Heroku-18

@BidhanMajhi When trying to scale using heroku ps:scale web=1 I get an error saying that they couldn't find the web process type. Procfile includes web: gunicorn prremia.wsgi — 12944qwerty

Go to your heroku dashboard, then in dashboard go to resources and check, if you have dynos. — Bidhan Majhi

@BidhanMajhi It tells me that I haven't made a Procfile but as I said above, I do, and I made sure to push it onto heroku. — 12944qwerty

Change your Procfile to web: gunicorn prremia.wsgi --log-file - And make sure you commit it. — Bidhan Majhi

Make sure your put your Procfile at the root of project along with manage.py. Also make sure you pushed the code from your project root. Bind port dynamically in your Procfile. Here's an example:-

web: gunicorn --bind 0.0.0.0:$PORT prremia.wsgi

$PORT is an environment variable. You must do scaling too.

Note: Make sure your project name exactly matches with <project_name>.wsgi in your Procfile.

I have made sure to push my Procfile and I did scale, but I how would I set this all up. (I mean the IP and $PORT)

MD. Khairul Basar Over a year ago

Just put the content in your Procfile as I've mentioned.

So, 0.0.0.0.$PORT is the website?? Wut? I'm really confused

Google and read some basic stuff about ip address and you'll find out. For now try to build again putting those content in your Procfile.

Hmm, still not working. But I did find something interesting... The error also says no module named 'prremia'

Some time silly mistake is there when some one create Procfile as text file so use the given command in your cmd to generate Prockfile:-

echo "web: python app.py" > Procfile

// I hope my answer help you.
