Django
Django is a high-level, free and open-source web framework written in the Python programming language that facilitates the rapid development of complex, database-driven websites through its emphasis on clean, pragmatic design and the "Don't Repeat Yourself" (DRY) principle.[1][2] Developed initially in 2003 by Adrian Holovaty and Simon Willison while working at the Lawrence Journal-World newspaper in Kansas, it evolved from internal tools used to build news applications under tight deadlines, prioritizing reusability, security, and scalability.[1] The framework was publicly released in July 2005 and is now maintained by the Django Software Foundation, an independent non-profit organization dedicated to its advancement.[1][3] Django employs a Model-Template-View (MTV) architectural pattern—a variant of the traditional Model-View-Controller (MVC)—where models manage data and database interactions, templates handle presentation logic, and views orchestrate the application's response to requests.[1] This structure, combined with its "batteries-included" philosophy, provides built-in components for common web development tasks such as URL routing, authentication, administration interfaces, and object-relational mapping (ORM), enabling developers to focus on application logic rather than boilerplate code.[2] Its design supports scalability, powering high-traffic sites including Instagram and Pinterest, while incorporating security features to mitigate common vulnerabilities like SQL injection and cross-site scripting.[1] Since its inception, Django has become one of the most influential frameworks in the Python ecosystem, with regular releases—such as version 5.1 in 2024—introducing enhancements in performance, async support, and internationalization, reflecting its adaptation to modern web demands without compromising core principles of developer productivity. Its enduring popularity stems from empirical success in production environments and a community-driven evolution that favors pragmatic solutions over experimental trends, though it has occasionally drawn critique for its opinionated approach in comparisons to lighter alternatives.[1]Technology
Web framework
Django is a high-level, open-source web framework written in Python, designed to enable rapid development of complex, database-driven websites with clean, pragmatic code.[2] It follows a "batteries-included" philosophy, bundling reusable components such as an object-relational mapper (ORM), authentication system, admin interface, and form handling to minimize boilerplate and accelerate prototyping.[4] This approach prioritizes developer productivity while enforcing scalable structure, making it suitable for applications ranging from small prototypes to large-scale sites like those of The Washington Post and Instagram.[5] The framework originated in 2003 as an internal tool at the Lawrence Journal-World newspaper in Lawrence, Kansas, where developers Adrian Holovaty and Simon Willison created it to efficiently build feature-rich web applications under newsroom deadlines.[5] Named after Belgian jazz guitarist Django Reinhardt, it transitioned to open-source status with its first public release in July 2005, marking the initial commit to a public repository on July 13 of that year.[6] By version 1.0 in September 2008, Django had stabilized core APIs, and as of October 2025, the latest stable release is version 5.1, supporting Python 3.10 through 3.13. Django's architecture adheres to the Model-Template-View (MTV) pattern, a variant of Model-View-Controller (MVC) that separates concerns for maintainability: models define data structures and interact with the database via the ORM; views process HTTP requests, execute business logic, and return responses; templates handle dynamic HTML rendering without embedding logic. The framework's URLconf system maps requests to views declaratively, while middleware enables pluggable request/response processing, such as for sessions or security. Key components include:- ORM: Abstracts database operations into Python classes, supporting multiple backends like PostgreSQL, MySQL, and SQLite without raw SQL for most tasks.
- Admin interface: Auto-generates CRUD interfaces for models, customizable for non-technical users.
- Forms and validation: Handles user input securely, integrating with models for data integrity.
- Security features: Built-in protections against SQL injection, cross-site scripting (XSS), cross-site request forgery (CSRF), and clickjacking.
