Creating a virtual environment

We need to create a virtual env for our app to run in: More Here Run this command in whatever folder you want to create your venv folder

python -m venv ./venv

Activate the virtualenv

# Mac/Linux
source ./venv/bin/activate

# Windows
venv\Scripts\activate.bat - May need to add full path (c:\users\....venv\Scripts\activate.bat)

Escape from venv

deactivate

Check packages installed in that venv

pip freeze

Install Django

pip install django

Create your project

django-admin startproject PROJECTNAME

Run Server (http://127.0.0.1:8000) CTRL+C to stop

python manage.py runserver

Create an app

python manage.py start app APPNAME

Create migrations

python manage.py makemigrations

Run migration

python manage.py migrate

Collect Static Files

python manage.py collectstatic

i think it should be: python manage.py startapp APPNAME and the create venv command should be using python3 for python version 3: python3 -m venv ./venv

if u have only python3 installed u can write python only python3 is basically needed to be written for machines running python 2.x and python 3.x

This is all great but I highly recommend using pipenv for handling your virtual environment. great tool.❤️

who installed python 3 we should replace python to python3

If you don't want to you python2 (or not inside a virtual env), you can change you bashrc file making a alias so python = python 3. This works for linux based systems.

Place this into ~/.bashrc or ~/.bash_aliases file
alias python=python3
After adding the above in the file, run source ~/.bashrc or source ~/.bash_aliases.

It's actually python only. On windows python on CLI works as python but on Mac and Linux it is installed as python3.

So i tried to learn django today, and my PC has latest version of python and django (3.2.3) and when i have typed the "django-admin startproject (My project name) it is showing an error even though my file path is also in a proper order. Can any one help me with this.

• pip freeze
• pip freeze > requirements.txt
• pip install -r requirements.txt

Working from the console with Python:

python manage.py shell

Create new object

from APPNAME.models import CLASSNAME

CLASSNAME.objects.create(key_1 = value_1, key_2 = value_2, key_n = value_n)

Can you do one for python 3?
