Django Fundamentals

Introduction

Django is a Python-based web framework. It follows the model-view-controller (MVC) architectural pattern. It is designed to help developers build applications quickly and with less code.

Syntax

To create a Django project, run the following command:

django-admin startproject projectname

To create a Django app, run the following command:

python manage.py startapp appname

To start the Django development server, run the following command:

python manage.py runserver

Example

from django.shortcuts import render
from django.http import HttpResponse

def hello(request):
    return HttpResponse("Hello, world!")

Output

When you navigate to http://localhost:8000/hello, you will see "Hello, world!" displayed on the page.

Explanation

This code defines a view function called "hello". When a user navigates to the URL associated with this function, the function responds with an HTTP response that says "Hello, world!".

Use

Use Django views to define the behavior of your application. Views can interact with models and templates to create dynamic and responsive applications.

Important Points

• Views are Python functions that respond to HTTP requests.
• A view function returns an HTTP response.
• Views can interact with models and templates to create dynamic and responsive applications.

Summary

Django views are an essential part of building web applications with Django. They define the behavior of your application and allow you to interact with models and templates to create dynamic and responsive websites. Use views to create custom behavior that can't be achieved with basic HTML and CSS.
