Explain

Django provides a full-stack web framework with batteries-included philosophy.

It uses Python and emphasizes reusability, rapid development, and security.

Supports ORM for database management, templating for HTML, and routing for URL mapping.

Includes built-in authentication, admin interface, and form handling.

Widely used for building web applications from simple sites to complex enterprise apps.

Core Features

Models for database tables and relationships

Views for request handling

Templates for dynamic HTML rendering

Forms for input validation and processing

Signals and middleware for extensibility

Basic Concepts Overview

Project: container for all settings and apps

App: modular component of a project

Model: database table representation

View: logic to process requests

Template: HTML rendering layer

Project Structure

project_name/ - project root and settings

app_name/ - app-specific models, views, templates

manage.py - CLI utility

templates/ - HTML templates

static/ - CSS, JS, images

Building Workflow

Create Django project and apps

Define models and migrate database

Write views and connect URLs

Create templates and static files

Test and run server locally

Difficulty Use Cases

Beginner: static site or blog

Intermediate: CRUD application with database

Advanced: REST API with Django REST Framework

Expert: Multi-app enterprise project

Architect: Scalable SaaS or e-commerce backend

Comparisons

Django vs Flask: Django is full-stack, Flask is lightweight

Django vs FastAPI: Django is synchronous and batteries-included, FastAPI is async and lightweight

Django vs Rails: Python vs Ruby, similar batteries-included philosophy

Django vs Express.js: Python backend vs Node.js backend

Django vs NestJS: Python full-stack vs Node.js modular TypeScript framework
