How to deploy Python Django project to heroku?

Deploy python django project from local to heroku

for macOS intallation:

brew install heroku 

→ connect to your heroku account with your email and your password

heroku login

→ to create heroku-app

heroku create <your-app-name>

need to web WSGI HTTP Server so we can install gunicorn in the django project file

pip install gunicorn

→ need to add this file in the django project file because of heroku define this file as configuration

Procfile(in this file define a applications path)

web: gunicorn <your wsgi.py directory>.wsgi — log-file -

to deploy the app, all required libraries is been writing in requirements.txt that are used by django-project:

pip freeze > requirement.txt

runtime.txt → python-3.9.5 (look supported python version to heroku-django)

You can find explanation as video with Turkish language:

→ in project directory with bash

git init
git add .
git commit -m “<your messages>”
git push heroku master

→ connect to remote heroku.git repo

heroku git:remote -a <project_name>

→ if you have static file at your project

pip install django-heroku

**Be sure to add “django-heroku” to your requirements.txt file as well.

Add the following import statement to the top of settings.py:

import django_heroku

Then add the following to the bottom of settings.py:

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

Configuring Django Apps for Heroku

in settings.py:
