Step 1. Create a Procfile in your project root and add the following line.

    web: gunicorn your_project_name.wsgi

Step 2. Go to the command line and install psycopg2, gunicorn, django-heroku and create requirements.txt

    pip install psycopg2
    # And NOW… you’ll be able to install django-heroku 
    pip install gunicorn
    pip install django-heroku
    pip freeze > requirements.txt

Step 3. In your app/settings.py

    import django_heroku 

    # Then all the way at the bottom of the file
    # ... 

    django_heroku.settings(locals()) 

Step 4. push it to heroku

    # login to your heroku
    heroku login

    # create new app if one doesn't yet exist
    heroku create

    # create a new postgres database for your app
    heroku addons:create heroku-postgresql:hobby-dev

    # migrate your database to the heroku app
    heroku run python manage.py migrate

    # before you do this, make sure to add your SECRET_KEY to your env variables in your heroku app settings
    git add .
    git commit -m "deploy to heroku "
    git push heroku master
