Install Django

Before you can use Django, you’ll need to install it. Our complete installation guide covers all the possibilities; this guide will get you to a simple, minimal installation that’ll work while you walk through the introduction.

For linux :

pip install django

For Windows :

python -m pip install django

Verify installation

on python terminal we will write

>>> print(django.get_version())2.1

Write your first Django app

Open command prompt to create new django project we should write on terminal the following command :

>> django-admin  startproject firstdemoproject 

now we will move to the folder and create a new app inside project folder

 >>cd firstdemoproject >> django-admin startapp app1

it will create required folders inside the directory structure.

Register your App

â??â??â??â??manage.pyâ??â??â??â??app1â??        settings.pyâ??        urls.pyâ??        wsgi.pyâ??        __init__.pyâ??â??â??â??requirements.txt

find the file with name settings.py and inside that file look for following code :

INSTALLED_APPS = [    'django.contrib.admin',    'django.contrib.auth',    'django.contrib.contenttypes',    'django.contrib.sessions',    'django.contrib.messages',    'django.contrib.staticfiles','app1']

add your app name as the last entry in the file and save and close the file.
A view is a place where we put the "logic" of our application, a webpage is basically a view in django.

Adding code to views.py

from django.shortcuts import renderfrom django.http import request,HttpResponsedef homepage(request):    return HttpResponse("this is first page")

save and close the file.

Adding url to urls.py

from  app1.views import homepageurlpatterns = [    path('admin/', admin.site.urls),    path('homepage/',homepage)]

now to Run the program type the following command at command prompt as folows :

>>python manage.py runserver

while your program is in running state ,open your browser and open url as follows :

http://localhost:8000/homepage

it will display your very first django app.

Woaw!! what a beautiful start !!
