My website works fine on localhost, but not on Heroku (it just crashes)

TurtleBuster69 · August 2, 2020, 7:32am

I read through the logs and found this confusing error.

django.core.exceptions.ImproperlyConfigured: Requested setting LOGGING_CONFIG, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

This is a bit weird because this is what my wsgy.py contains:

import os

from django.core.wsgi import get_wsgi_application

application = get_wsgi_application()

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'PersonalWebsite.settings')

I looked it up on DuckDuckGo already, and tried answers/solutions from StackOverflow and some random websites, but it still doesn’t work ;-;

It’s really weird because this works fine when I open it on localhost, but not on my Heroku app website thing.

It works fine on your localhost because django is configured to automatically identify your wsgi or asgi.py file when runserver is executed.

When deploying to a service like Heroku, AWS, or Digital Ocean, you need to tell the service where that file is so it can constantly run your software. Do you know what service Heroku is using in the background? Nginx, maybe?

It does look as if you are missing the Procfile for your Heroku deployment. I recommend you look at this doc: https://devcenter.heroku.com/articles/django-app-configuration

Turns out I accidentally screwed up my wsgi file. I made a new project and compared it with my current project, and then I found a solution!
I changed my code from this:

application = get_wsgi_application()

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'PersonalWebsite.settings')

to this:

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'PersonalWebsite.settings')

application = get_wsgi_application()

That’ll do it! Now, if this same issue occurs in the future, you know the resolution
