Django is a powerful web framework that is widely used by developers for building web applications. It is written in Python and follows the Model-View-Template (MVT) architectural pattern. In this article, we will explore the basics of Django and its features.
About Django Web Framework
Django is a python web framework that helps developers to build web applications quickly and easily. If you already know python, this can be a good framework to learn in order to create fully functioning websites in a fairly simple way.
Django was created by Adrian Holovaty and Simon Willison in 2003 while working on a news website called the Lawrence Journal-World. They wanted to build a framework that would enable them to build complex web applications quickly and efficiently. They released the framework as an open-source project in 2005, and it has since become one of the most popular web frameworks in the world.
Django provides a bunch of tools and configurations that help you automate the repetitive aspects of web development (such as authentication, database connections and security).
It is free, open source and encourages rapid development. The point is for you to take your idea and develop it as soon as possible using the tools that are already provided without having to re-invent the wheel.
Also Django is really focused on security, which makes it great for developers who are just starting out and might not have a comprehensive idea about assuring security in their web applications.
Django is also highly scalable and is used by many massive organisations such as Instagram, NASA, Udemy and many more. If these massive companies use Django, you can be rest assured that it would be a scalable and reliable choice for your web application.
Features of Django Web Framework
Django has many features that make it a popular choice for building web applications. Some of its key features include:
- Object-relational mapping (ORM): Django’s ORM allows you to interact with databases using Python objects. This eliminates the need for writing complex SQL queries and makes it easier to work with databases.
- URL routing: Django’s URL routing maps URLs to specific views or functions in their application making it easy to build complex web applications with multiple pages and features.
- Template engine: Django’s template engine helps you to create dynamic HTML pages using Python code making it easy to build web applications that are both flexible and dynamic.
- Built-in admin interface: Django comes with a built-in admin interface. This way you can check, add, delete or update your web application’s from the web interface without having to build custom administration interfaces.
- Security features: Django comes with built-in security features such as cross-site scripting (XSS) protection, SQL injection protection, and password management.
How does the Django Web Framework work?
Django follows the Model-View-Template (MVT) architectural pattern. This pattern separates the application logic into three main components: models, views, and controllers.
- Model: The models component of Django is responsible for defining the application’s data models. This includes defining the structure of the database tables, as well as any constraints or relationships between tables.
- View: The View handles the user interface logic and controls the flow of data between the Model and the Template. It receives requests from the user, retrieves data from the Model, and returns a response to the user.
- Template: The Template defines how the data is presented to the user. It uses the data provided by the View to generate HTML pages, which are then sent to the user.
Conclusion
Django is a powerful web framework that makes it easy to build web applications quickly and efficiently.
Its features, such as ORM, URL routing, and template engine, allow you to focus on building the business logic of their application instead of dealing with low-level details. The built-in admin interface and security features make it a popular choice for building complex web applications.
All in all, if you’re a Python developer looking to build web applications, Django is definitely worth considering.
