What is Django and How does Django work?

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.

In this article, we will look at Django in detail and will try to answer all your questions with regards to this most popular Python Web framework.

Let’s start.

What is Django

Django is a free and open-source web application framework written in Python.

It is maintained by the Django Software Foundation, a non-profit organization started as part of the Python Software Foundation.

Its primary goal is to ease the creation of complex, database-driven websites that don’t require manual coding.

Django was originally developed in the Lawrence Journal-World newspaper offices in 2004 by Adrian Holovaty and Simon Willison.

They wanted to implement a news site with both news articles and associated photographs, while avoiding repetition of content such as captions and photo descriptions.

The framework they developed allowed the News section of the paper’s website to be changed by non-technical staff and editors.

Django’s primary goal is to allow rapid development of database-driven web sites. Django emphasizes reusability and “pluggability” of components, rapid development, and the principle of don’t repeat yourself (DRY).

It allows developers to use HTML or other templating languages to specify the structure of a document, rather than programming each page directly.

It automatically sends an HTTP cookie with every response. The development philosophy is summarized as “Batteries included but swappable.”

Django also provides much support for serving static files, including transparent caching within the web server, file access via HTTP, and even automatic selection of the appropriate type of compression to use for a specific file.

Standardized ways of connecting to different types of databases are provided, including support for popular relational database systems such as MySQL, PostgreSQL, SQLite, Oracle Database and Microsoft SQL Server.

Internal checks ensure that data meets the requirements of the original application programming interface (API).

Django uses PostgreSQL as its “default” database. While the Python language supports almost any database that can be used with Python’s standard DB-API, Django’s use of the high-level abstractions defined by the model/view/controller (MVC) pattern requires a database with certain features. Django supports all major databases.

Django also provides optional integration with various JavaScript libraries such as jQuery and Bootstrap, which allows the developer to easily apply a theme or create a custom template.

There are a range of user interface elements called “widgets” that provide additional functionality, from sliders and tabs to accordion panels and Flash messages.

Django also provides APIs for user authentication and authorization. The Django authentication system supports a number of common mechanisms, such as username and password login, and logins using external sites like Facebook and Twitter.

Django includes with its framework the ability to interact with Web-based forms created by users of the site and allows developers to follow standard practice in working with these forms.

Forms are key to the MVC model used by Django, allowing developers to use form processing in their views and create dynamic web pages on the fly.

Though written in Python, Django was designed specifically for Web development rather than scripting. It focuses on automating as much of the overhead work as possible without adding additional syntactic overhead.

For instance, Django automatically translates incoming requests into the format expected by models, passes them to the appropriate views and returns the resulting responses to the user or developer.
