1. At first create account or login in heroku
2. Download heroku-cli from here or visit the website

3. Create a virtual environment:

pip install virtualenv

virtualenv anyname

• After creating virtual environment activate your vitualenv

pip install django gunicorn django-heroku

You can install specific version like pip install django==2.2

• Copy / Transfer your django-project in that virtual environment
• Add your dependencies to requirements.txt by typing in the terminal

pip freeze > requirements.txt

4. Setup your django-project before starting heroku-deployment

• Don't forget to add this in settings.py

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, "static")
]

First, and most importantly, Heroku web applications require a Procfile

• This file is used to explicitly declare your application’s process types and entry points. It is located in the root of your repository

Procfile

web: gunicorn yourprojectname.wsgi:application --log-file -

• 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())

• You can also made these changes in settings.py

# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = False

ALLOWED_HOSTS = ["*", "localhost"]

# Application definition
MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'whitenoise.middleware.WhiteNoiseMiddleware', # --> only add this line
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

5. Final process of heroku-deployment for your django-sqlite application

• Open your terminal / cmd and run the following commands

heroku login

• Now create your heroku-app using this command

heroku create yourappname

• After run this command you can see:

C:\Users\SUPRATIM\Desktop\UselessDjangoApp>heroku create yourappname
Creating app... done, yourappname
https://yourappname.herokuapp.com/ | https://git.heroku.com/yourappname.git

git status
git init
git remote add heroku https://git.heroku.com/yourappname.git
git remote -v

git status
git add .
git status
git commit -m "initial commit by yourname"

• Add runtime.txt in the root folder of your project / repository and write the current python version (used for your project) in the file

python-3.9.4

Caution:

• If you are using django==2.2 then change the version of psycopg2==2.9.x with psycopg2==2.8.6 like this

pip uninstall psycopg2==2.9.x && pip install psycopg2==2.8.6

pip freeze > requirements.txt

• After this check your requirements.txt at-least once

Django==2.2
django-heroku==0.3.1
gunicorn==20.1.0
psycopg2==2.8.6
pytz==2021.3
