Django is an open source web framework written in Python that follows a model-view-presenter scheme. It was originally developed to manage the Lawrence Journal-World news site and was released in July 2005 under a BSD license . It is named after the jazz guitarist Django Reinhardt .

Some versions receive longer support and are offered as LTS . From version 2.0, the versioning is applied to SemVer .

philosophy

Django is the Python equivalent of Ruby on Rails in many ways . For example, Django also focuses on adhering to the DRY principle .

In contrast to this, Django does not rely on an implicit, but on the explicit configuration of an application. This is reflected, for example, in the URL configuration, which is made explicitly with regular expressions and thus creates a mapping of a URL to a Python function. Other web frameworks often take the route of implicit URL mapping via directories and function names.

features

Model template view in Django

Screen view of the optional admin interface, which also manages users

• Integrated object-relational mapping for the database systems MySQL , Oracle , PostgreSQL and SQLite
• Connection to other database systems (e.g. Db2 and Microsoft SQL Server ) via third-party backends
• automatically generated administration interface suitable for production
• flexible URL configuration with regular expressions
• extensive template language with inheritance support
• Internationalization support
• Cross-site scripting protection
• further modules that can be used as required:
  • built-in caching
  • Authentication system
  • Comment system
  • Search engine sitemaps creation
  • Support of the simplified markup languages Textile , Markdown and ReStructuredText
  • Tools for creating RSS and Atom feeds
  • Module for geographic information systems

Almost every feature of Django can be easily extended without changing the framework's original source code . For example, self-created modules can be loaded within templates in order to expand the scope of the template language. Django also allows you to create reusable applications that can be combined with one another as required.

Django runs on the Apache web server with mod wsgi or another WSGI compatible web server. It is also possible to run Django as FastCGI . Django also contains its own web server designed and tailored for the development.

Django Software Foundation
