heroku - Django Deployment - No web processes

Question

I created an application using Django 3.1.5 and for some reason, it does not deploy correctly. I will share what I did and have it.

I have set up my Procfile and I have my requirements.txt, I did the deployment as I told on the website, but I am still getting an error.

computer setting image and Procfile

On my settings.py I have this:

# on the top of the file
import django_heroku

# on the bottom of the file
STATIC_URL = '/static/'

STATIC_ROOT = os.path.join(BASE_DIR, 'static')
STATIC_DIRS = [
    os.path.join(BASE_DIR, 'todo/static')
]

LOGIN_URL = '/login'

# Activate Django-Heroku.
django_heroku.settings(locals())

Procfile

web: gunicorn todowoo.wsgi

After I finish the deployment I get this error

Application error An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. heroku logs --tail for details

Here are the details:

I tried to run heroku ps:scale web=1 and I got this:

Scaling dynos... !
 !    Couldn't find that process type (web).

Any idea how to solve this? Thank you.

Answer 1

I have encountered a similar situation very recently. I followed these commands to successfully deploy django app into heroku

• First make sure you have requirements.txt and Procfile

• In Procfile, the contents were like this

• web: python manage.py runserver 0.0.0.0:$PORT

• And run python manage.py collectstatic just to make sure no errors from collectstatic

• Then these commands in cmd

• heroku login

• Then login from browser

• git init

• heroku git:remote -a app_name

• git add .

• git commit -am "first commit"

• git push heroku main

• heroku run python manage.py migrate

• heroku open
