Learn DJANGO with Real Code Examples

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.

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

Project: container for all settings and apps

App: modular component of a project
