Step-by-step procedure to post your project to Publicly accessible Heroku Server

#python #django #linux

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.

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.

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

This adds all the files to git.

This commits all folders to git.

heroku git:remote -a subdomainname

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)

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
