Django – Python’s Popular Web Framework – Guide

Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. Created by a group of skilled developers, This is designed to help developers take applications from concept to completion as quickly as possible. Its “batteries-included” philosophy provides numerous built-in features like authentication, URL routing, template engines, and more, making it one of the most popular frameworks for web development.

Key Features of Django

1. ORM (Object-Relational Mapping):Django’s ORM enables developers to interact with their database, such as PostgreSQL, MySQL, SQLite, and Oracle, using Python code instead of writing complex SQL queries. This abstraction layer simplifies database manipulation and enhances code readability and maintainability.
2. Admin Interface:One of Django’s standout features is its automatically generated admin panel. With minimal configuration, developers can manage the application’s data and content through a user-friendly interface, making backend management efficient and accessible.
3. Security:Django includes built-in protections against many common security threats, such as SQL injection, cross-site scripting (XSS), cross-site request forgery (CSRF), and clickjacking. These features help developers secure their applications without requiring extensive additional coding.
4. Scalability:Django is built to scale, making it suitable for both small and large projects. Its modular architecture and the ability to handle large volumes of traffic and data make it an excellent choice for high-traffic websites and applications.

   content = models.TextField()
   created_at = models.DateTimeField(auto_now_add=True)

2. Migrate Database: Apply the model changes to the database:

   bash

   python manage.py makemigrations
python manage.py migrate

3. Create Views: In your views.py file, define views to handle displaying blog posts:

   python

   from django.shortcuts import render
from .models import Postdef index(request):
   posts = Post.objects.all()
   return render(request, ‘index.html’, {‘posts’: posts})

   python

   from django.urls import path
from . import viewsurlpatterns = [
   path(”, views.index, name=‘index’),
   ]

5. Templates: Create HTML templates to display your blog posts in the templates directory.
