  • Open your project folder

  • install pipenv

  • on cmd: pip install pipenv

  • Install git ( check git --version)

  • Install Heroku CLI (Heroku Command Line Interface)

  • Can be installed from 'Getting Started on Heroku with Python' web page.

  • After installing, open cmd and enter 'Heroku login' and enter login credentials same as our Heroku account login.

  • This will log in Heroku, which is a sign that Heroku is properly installed on our computer.

  • Create a virtual environment

  • Virtual environment isolates our project. Anything we install within the virtual environment does not affect the rest

of the computer and vice-versa.

  • on cmd: vitualenv . (to install virtual environment)

  • Activate the virtual environment by running activate.bat files within the scripts folder.

  • Check which version Django, requests you have and install it

  • On cmd: pip install django==2.1.11 (to install Django on our virtual environment)

  • On cmd: pip install requests==2.19.1 (to install requests package on our virtual environment)

  • Run manage.py and then stop it

  • on cmd: python manage.py runserver (this runs our project locally)

  • Now Django Heroku requires Procfile

  • type 'web: gunicorn projectname.wsgi' on Procfile

  • Install gunicorn

  • On cmd: pip install gunicorn

*'gunicorn' is required by Heroku to run our website on the server.

  • Install django-heroku

  • On cmd: pip install django-heroku

  • Add stuff to settings.py 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())

  • pip freeze > requirements.txt

  • Whenever we upload something to Heroku, it goes to requirements.txt file and it installs the requirements on the server.

  • On cmd: pip freeze (this displays the packages needed on the Heroku server.

  • On cmd: pip freeze > requirements.txt (this creates a new file on your project folder which contains all the requirements

that are needed by Heroku to install.

  • To create an app on heroku

  • On cmd: Heroku create subdomainname (choose the name as you wish)

  • This creates the app with the name you give. This can be verified by opening our Heroku account dashboard.

  • git status git commands

  • git init

This creates a .git folder on our project folder that means git is initialized.

  • git status

This shows all the folders that are not added to git.

  • git add -all

This adds all the files to git.

  • git commit -m "commit message"

This commits all folders to git.

  • Now we have to set remote to Heroku using below command.

heroku git:remote -a subdomainname

  • git push heroku master

This command pushes files to Heroku server.

  • Open up the website from subdomainname.herokuapp.com on the browser.

  • Admin panel not working. heroku run bash. Migrations

  • Now create superuser to access admin panel. To create superuser follow below steps:

On cmd: heroku run bash (This will give access to files uploaded on Heroku Server)

bash gives access to files uploaded in Heroku server.

$ls - shows directories inside Linux

$python manage.py migrate (runs migrations)

$python manage.py createsuperuser (To create superuser)

  • Now we can log in to administrator panel using below link

subdomainname.herokuapp.cpm/admin/

  • To update any files on the project (ex: HTML pages) and push changes to Heroku server

On cmd: git status (shows updated or new files added)

git add -all

git commit -m "commit message"

git push heroku master
  • Now your web app is live on Heroku Server
