Object-relational mapper
Define your data models entirely in Python. You get a rich, dynamic database-access API for free — but you can still write SQL if needed.
Automatic admin interface
Save yourself the tedious work of creating interfaces for people to add and update content. Django does that automatically, and it’s production-ready.
Elegant URL design
Design pretty, cruft-free URLs with no framework-specific limitations. Be as flexible as you like.
Template system
Use Django’s powerful, extensible and designer-friendly template language to separate design, content and Python code.
Cache system
Hook into memcached or other cache frameworks for super performance — caching is as granular as you need.
Internationalization
Django has full support for multi-language applications, letting you specify translation strings and providing hooks for language-specific functionality.
