Django's `from_queryset`: The Fix for Manager Relations
Discover why Django remains a top Python web framework in 2025. Our guide covers its 'batteries-included' philosophy, key features, and when to choose it.

Ever wondered how massive, data-heavy websites like Instagram or Pinterest are built and maintained? While there are many pieces to that puzzle, a big one is the web framework they're built on. In the world of Python, one name has consistently stood out for its power and pragmatism: Django.
But in a landscape flooded with new tools and technologies, is Django still relevant? The short answer is a resounding yes. Let's dive into what Django is, why its philosophy is so powerful, and whether it’s the right choice for your next project.
What Exactly Is Django?
Django describes itself as "the web framework for perfectionists with deadlines." That’s not just clever marketing; it’s a mission statement. At its core, Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. It follows the Model-View-Template (MVT) architectural pattern.
Instead of making you build everything from scratch, Django provides a comprehensive toolkit to handle the common (and often tedious) parts of web development. This lets you focus on what makes your application unique, rather than reinventing the wheel.
The "Batteries-Included" Philosophy: What It Really Means
You'll hear the phrase "batteries-included" a lot when people talk about Django. But what does that mean in practice? It means Django comes with almost everything you need to build a full-featured web application, right out of the box.
Think of it like buying a new gadget. A microframework like Flask might give you the core device and a power cord, letting you choose your own screen, keyboard, and software. Django gives you the whole package, fully assembled and ready to go. This includes:
- An ORM: A powerful way to interact with your database using Python code instead of raw SQL.
- An Admin Interface: A production-ready admin panel that's automatically generated from your data models.
- Authentication: A robust system for handling user accounts, permissions, and sessions.
- A Templating Engine: A designer-friendly language for creating dynamic HTML.
- Form Handling: A framework for generating, validating, and processing forms securely.
- Security Features: Built-in protection against common threats like Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), and SQL injection.
Django's Core Strengths You Can't Ignore
Django’s philosophy translates into tangible benefits that developers love. Here are a few of its killer features.
The Object-Relational Mapper (ORM)
If you've ever written complex SQL queries, you'll appreciate the beauty of Django's ORM. It lets you define your database tables as Python classes (called Models). Then, you can query your data using simple, intuitive Python code.
For example, to get all blog posts by a specific author, you'd write:
from myapp.models import Post
# Find all posts written by 'Alejandro'
posts = Post.objects.filter(author__name='Alejandro')This is not only easier to write and read, but it also makes your code more portable across different database systems (like PostgreSQL, MySQL, and SQLite).
The Legendary Admin Panel
This is arguably Django's most famous feature. With just a few lines of code, Django can generate a complete, secure, and customizable administrative interface for managing your site's content. For a new project, this means you have a functional back-office to create, update, and delete data from day one. It’s an incredible time-saver for content-driven sites, e-commerce platforms, and internal tools.
Security by Default
The web can be a dangerous place, but Django has your back. The framework's creators have built security into its very foundation. Django automatically handles many common security vulnerabilities that developers might otherwise overlook. By providing tools that prevent CSRF, XSS, and SQL injection, Django helps you build safer applications by default, letting you sleep a little better at night.
Proven Scalability
Some might think a framework with so much built-in could be slow or rigid. Django proves them wrong. Its component-based architecture allows you to scale different parts of your application independently. Don't take our word for it—some of the world's highest-traffic websites, including Instagram, Pinterest, Disqus, and the Washington Post, use Django to serve millions of users every day.
Django vs. Flask: A Head-to-Head Look
No discussion of Django is complete without mentioning its popular counterpart, Flask. They represent two different philosophies in web development. Here’s a quick breakdown:
| Feature | Django | Flask |
|---|---|---|
| Philosophy | Batteries-Included (Convention over Configuration) | Microframework (Minimalist and Extensible) |
| Out of the Box | ORM, Admin, Auth, Forms, Templating Engine | Routing, Debugger, and a WSGI server |
| Structure | Opinionated and structured; enforces a clear project layout. | Unopinionated; gives the developer complete freedom. |
| Learning Curve | Steeper, as you need to learn Django's way of doing things. | Gentler, as you can start small and add components as needed. |
| Best For | Complex, data-driven applications, CMS, e-commerce, social networks. | APIs, microservices, small-to-medium websites, or when you need full control. |
The bottom line: Neither is universally "better." Django is your go-to for building large, feature-rich applications quickly and securely. Flask is ideal when you want flexibility, a smaller footprint, or are building something more specialized like a simple API.
When Should You Choose Django?
With its robust feature set, Django shines in specific scenarios. You should strongly consider Django if your project involves:
- Complex, database-driven functionality: Think e-commerce sites, content management systems (CMS), or booking platforms.
- A need for a user-friendly admin interface: If you need to manage content, users, or products, Django's admin is a lifesaver.
- A tight deadline: The batteries-included approach lets you build and launch features incredibly fast.
- Security and scalability as top priorities: Django's built-in protections and proven track record make it a reliable choice for applications that need to be secure and grow over time.
Final Thoughts: Why Django Endures
In an industry that chases the new and shiny, Django’s endurance is a testament to its design. It strikes a rare balance between rapid development and long-term maintainability. By providing a structured, secure, and scalable foundation, it empowers developers to focus on building great products rather than getting bogged down in boilerplate code.
So, is Django still the king? For building robust, full-featured web applications with Python, it remains an unparalleled choice. It’s not just a framework; it’s a productivity machine built on years of best practices. If that sounds like what you need, it's time to give Django a try.
