Why Django Framework?
First, let’s understand how Django came into existence

❑ Django is a Python web framework
❑ A framework provides a structure and common methods to make the life of a web application
developer much easier for building flexible, scalable and maintainable web applications

➢ A Python web framework is a code library that provide
tools and libraries to simplify common web development
operations.

What is Django?

What is Django?
Django is a high-level and has a MVC-
MVT styled architecture.
Django web framework is written on
quick and powerful Python language.
Django has a open-source collection of
libraries for building a fully functioning
web application.

Django MVC-MVT Pattern

Django MVC-MVT Pattern
➢ MVC is slightly different from MVT as Django itself takes care of the Controller part.
➢ It leaves the template which is a HTML file mixed with Django Template Language (DTL).
Model View Template

Model View Controller
The developer provides the Model, the view and the template then just maps it to a URL
and Django does the magic to serve it to the user.

Hands on
Now, let’s create a basic Web App

Installation
Go to the link:
https://www.djangoproject.
com/download/
1
2 Install the latest
version of Django

Create a Project
$ django-admin startproject firstproject
Open the terminal and navigate to the folder where the project is to be created.
Firstproject/
manage.py
firstproject/
__init__.py
settings.py
urls.py
wsgi.py
This will create a "myproject" folder with the following structure:
1

Project Structure
“firstproject” folder is just your project container or
directory. You can rename it to anything you like.
firstproject/
firstproject
__init__.py
settings.py
urls.py
wsgi.py
manage.py

Project Structure
This folder is the actual python package of your project
which contains some default files.
firstproject/
firstproject
__init__.py
settings.py
urls.py
wsgi.py
manage.py

Project Structure
It is an empty file that tells python that this folder
should be treated as package.
firstproject/
firstproject
__init__.py
settings.py
urls.py
wsgi.py
manage.py

Project Structure
This contains the settings or the configurations of the
project.
firstproject/
firstproject
__init__.py
settings.py
urls.py
wsgi.py
manage.py

Project Structure
This file contains all the links of your project and the
function to call.
firstproject/
firstproject
__init__.py
settings.py
urls.py
wsgi.py
manage.py

Project Structure
It is an entry point for WSGI-compatible web services to
serve your project.
firstproject/
firstproject
__init__.py
settings.py
urls.py
wsgi.py
manage.py

Project Structure
It is a command line utility that lets you interact with the
Django project.
firstproject/
firstproject
__init__.py
settings.py
urls.py
wsgi.py
manage.py

Your First Web App
Congratulations! We have successful created a basic
Web App.

Components of Django
Now, let’s understand the components/ building blocks of Django

ORM
URLs and Views
Templates
Forms
Authentication
Admin
Internationalization
Security
ORM stands for Object-relational Mapper.
Deﬁne your data models. You get a rich, dynamic
database-access API for free but you can still write
SQL if needed.
from django.db import models
Class employees(models.Model):
firstname = models.CharField(max_length=10)
Lastname = models.CharField(max_length=10)
def _str_(self):
return self.firstname

URLs and Views
ORM
Templates
Forms
Authentication
Admin
Security
Like a table of contents for your app, it contains a
simple mapping between URL patterns and your
views.
from Django.shortcuts import
render
def index(request):
return HttpResponse
(<h2> Hey! Welcome to Django
tutorial</h2>)
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^$', views.index, name='index'),
]
URL
Mapping views and URL

Templates
ORM
URLs and Views
Forms
Authentication
Admin
Security
Templates are designed to feel comfortable and
for those who work with HTML, like designers and
front-end developers.
TEMPLATE_DIRS = (
'<workspace>/django_project/templates/',
)

Forms
ORM
URLs and Views
Templates
Authentication
Admin
Security
Django provides a powerful form library that handles
rendering forms as HTML, validating user-submitted
data, and converting that data to native Python types.

Authentication
ORM
URLs and Views
Templates
Forms
Admin
Security
It handles user accounts, groups, permissions and
cookie-based user sessions.
from django.contrib.auth.decorators import login_required
from django.shortcuts import render
@login_required
def my_protected_view(request):
return render(request, 'protected.html', {'current_user':
request.user})

Admin
ORM
URLs and Views
Templates
Forms
Authentication
Security
It is the most powerful part that reads metadata in
your models to provide a powerful and
production-ready interface that can be used to
manage content on your site.

ORM

Django offers full support for translating text into
different languages, plus locale-specific
formatting of dates, times, numbers and time
zones.
