Django REST API in 10 Steps with Django and DRF

🚀 FastAPI vs Django — Which One Should You Choose? As I continue exploring backend development, I took some time to understand the practical differences between FastAPI and Django — two powerful Python frameworks widely used in real-world applications. Here’s a simple comparison based on performance, use cases, and development experience: ⚡ FastAPI • High-performance framework designed for building APIs • Supports asynchronous programming (async/await) • Automatic API documentation (Swagger UI) • Ideal for microservices and ML model deployment 👉 Best for: Fast, scalable APIs and real-time applications 🌐 Django • Full-stack framework with built-in features • Includes authentication, admin panel, and ORM • Follows a structured “batteries-included” approach • Highly reliable for large-scale applications 👉 Best for: Complete web applications and enterprise systems ⚖️ Key Differences • Speed: FastAPI is faster, Django is stable and feature-rich • Focus: FastAPI → APIs | Django → Full web apps • Flexibility: FastAPI is lightweight | Django is structured • Development: FastAPI for performance, Django for rapid full-stack development 🧠 My Takeaway Choosing the right framework depends on your use case: ✔ Use FastAPI for performance-driven APIs ✔ Use Django for building complete, scalable applications Learning these differences helped me understand not just the tools, but also when to use them effectively. 10000 Coders Manivardhan Jakka #FastAPI #Django #Python #BackendDevelopment #WebDevelopment #APIs #LearningJourney 🚀

🚀 My Journey from Django to Flask: 5+ Years of Backend Development Lessons After working with both Django and Flask extensively at NIIT Limited and now at Clcoding, I've learned that the "which framework is better" debate misses the point entirely. Here's what 5+ years of real-world Python backend development taught me: WHEN TO USE DJANGO: ✓ Enterprise applications needing rapid development ✓ Projects requiring built-in admin panels and ORM ✓ Large-scale applications with complex data relationships ✓ Teams that benefit from "batteries-included" approach Example: At NIIT Limited, we built a multi-user data processing platform with Django. The built-in admin panel and ORM saved us weeks of development time. WHEN TO USE FLASK: ✓ Microservices and API-first architectures ✓ Projects requiring maximum customization ✓ Lightweight applications with specific requirements ✓ When you want full control over components Example: For a recent automation project at Clcoding, Flask's minimalist approach let us build exactly what we needed without unnecessary overhead. COMMON PITFALLS I'VE ENCOUNTERED: Django: → N+1 query problems (always use select_related and prefetch_related) → Bloated views mixing business logic with presentation → Not leveraging Django's caching framework early enough Flask: → Reinventing the wheel for basic features → Poor project structure as applications grow → Security oversights without Django's built-in protections MY PRACTICAL TIPS: 1. Start with Django if you're building your first production app 2. Learn Flask to understand web frameworks at a deeper level 3. Use Django for MVPs and enterprise apps 4. Choose Flask for APIs, microservices, and cloud-native applications 5. Master one framework deeply before switching The real skill isn't choosing the "right" framework – it's knowing when to use each one based on project requirements, team expertise, and scalability needs.

Day 95 – Django Model Relationships, Admin Integration & Media Handling Today I worked on building dynamic Course and Teacher management in Django by connecting frontend and backend with database-driven content. 🔹 Created a new Course Details page with navigation integration using templates, views, and URL routing. 🔹 Built a Details model with: • Course_name (CharField) • Course_dtls (TextField) Learned the importance of: ✔ null=True ✔ blank=True ✔ max_length ✔ Difference between CharField and TextField 🔹 Performed database migration using: makemigrations migrate 🔹 Registered models in Django Admin for easy backend management. 🔹 Fetched database content dynamically to the frontend using: Details.objects.all() and displayed it with Django template for-loops. 🔹 Created a second model: Teacher Fields included: • Teach_name • Course_name (ForeignKey with Details) • Teach_img (ImageField) This helped me understand: ✔ ForeignKey relationships ✔ on_delete=models.CASCADE ✔ Connecting two models in Django 🔹 Installed Pillow for image handling and configured: MEDIA_ROOT MEDIA_URL Also updated project urls.py for serving media files properly. 🔹 Successfully fetched teacher images from backend to frontend using: {{ i.Teach_img.url }} Today’s learning gave me a strong understanding of Django model relationships, admin panel usage, migrations, and media file management. Step by step, backend development is becoming more practical and exciting! 💻 #Django #Python #WebDevelopment #BackendDevelopment #FullStackDevelopment #DjangoDeveloper #SoftwareDevelopment #PythonDeveloper #DatabaseManagement

I have been learning Django for just one month. And I already found something that genuinely shocked me something no other backend framework I have touched actually does. Django ships with a built-in Admin panel. Not a template. Not a third-party library you install separately. It is literally baked into Django by default. You register your model and Django builds you a working dashboard search, filters, pagination, permissions all of it. @admin.register(Product) class ProductAdmin(admin.ModelAdmin):   list_display = ['name', 'price', 'category']   search_fields = ['name']   list_filter  = ['category'] That is it. Five lines. And you have a fully working admin interface your client can log into right now. I came from React and Next.js. On the frontend, something like this would take days routing, auth, tables, filters, state management. Django just… gives it to you. Now here is the part that really got me thinking. Django Admin was built in 2005. The web was completely different back then. But the people who built it made a decision give developers a complete, working back-office system by default, not as an optional add-on. Twenty years later, that same decision is what makes Django one of the best frameworks to connect with AI right now. Because you already have the interface. You already have the data layer. You just plug an AI model in and suddenly your admin panel can summarize records, flag unusual entries, or generate content automatically without building a separate tool from scratch. I am one month into Django and I already feel like I skipped three months of backend work. If you are a frontend developer thinking about learning backend honestly, start with Django. The learning curve is real but what it gives you in return is worth it. #Django #Python #AI #LearningInPublic #FullStackDeveloper #WebDevelopment #BackendDevelopment

🚀 Django Learning Journey – Project Update Recently, I built an Inventory Management System using Django 📦 Here’s what I implemented: ✔ Add, Update & Delete Products (CRUD Operations) ✔ Stock Management & Tracking ✔ Organized Models & Database Design ✔ Django Admin Customization ✔ Clean UI using HTML, CSS & Bootstrap This project helped me understand how real-world systems handle data management and business logic — especially how backend systems track and update inventory efficiently. One key takeaway: 👉 Building CRUD-based systems is the foundation of most real-world applications. 💻 Check out the project here: https://lnkd.in/dyiD3w7d Next step: I’m continuing to strengthen my backend skills and moving deeper into Django REST Framework (DRF) to build scalable APIs. I’m sharing my journey to stay consistent and connect with other developers. #Django #BackendDevelopment #Python #WebDevelopment #LearningInPublic #Projects

Excited to share something I’ve been working on! I’ve officially published my first Django utility package on PyPI: django-migration-testgen (v0.1.0). As a developer, I’ve always felt that Django migrations are powerful but often under-tested. In real-world projects, especially in large teams and production systems, migrations can silently break things if not properly validated. That’s where this tool comes in. What does it do? It automatically scans your Django apps and generates ready-to-use test files for your migration files, allowing you to confidently verify schema changes, both forward and backward. Why I built this: - Writing migration tests manually is repetitive and often skipped - Migration issues can break production deployments - CI pipelines should validate schema evolution, not just code Key Features: - Auto-discovers all migration files across apps - Generates structured test files per migration - Uses Django’s MigrationExecutor for real execution testing - Supports forward and rollback testing - Dry-run, force overwrite, and custom output directory support - Easy integration into CI/CD pipelines Install & try it: ```bash pip install django-migration-testgen ``` Then just run: ```bash python manage.py generate_migration_tests ``` My goal with this project is simple: make migration testing effortless, scalable, and reliable for Django developers. This is just v0.1.0, and I’m planning to improve it further with smarter test generation, better customization, performance optimizations, and community feedback. If you’re working with Django, I’d love for you to try it out and share your thoughts.

If you're starting backend development, you've probably heard about Django. But why do so many developers choose it? At first, I thought it was just another framework. But after spending time with it, I realized Django is more than that it’s a complete ecosystem for building real-world applications. Here’s why 👇 1️⃣ Batteries included Django comes with almost everything built-in: Authentication Admin panel ORM Security features You don’t waste time choosing libraries or setting up basic things. You focus on building. 2️⃣ Fast development Django is designed for speed. From idea → to working product, the process is much faster. That’s why it’s widely used for: Startups MVPs Rapid prototyping Less setup. More building. 3️⃣ Security Security is not optional in backend. Django handles many common vulnerabilities out of the box: ✔ SQL Injection ✔ CSRF attacks ✔ XSS This reduces risks, especially for beginners. 4️⃣ Scalability Many people think Django is only for small projects. That’s not true. Platforms like Instagram used Django at scale. With proper architecture, Django can handle high traffic and complex systems. 5️⃣ Clean and structured One thing I personally like: Django forces you to follow a structured approach. Apps Models Views Templates It may feel strict at first but later you realize it helps you write better code. 6️⃣ Strong community Django has been around for years. That means: ✔ Tons of documentation ✔ Large community support ✔ Ready-to-use packages Whenever you're stuck solutions exist. 💡 My takeaway: Django is not the easiest at the beginning. But it teaches you how real backend systems are built. Not just writing endpoints, but thinking in terms of architecture. If you're serious about backend development, Django is definitely worth learning. Not because it's “popular” but because it builds strong fundamentals.

🚀 Django Backend: All Crucial Concepts & Features You Should Know If you're diving into backend development, Django is one of the most powerful frameworks built on Python. Here’s a clean breakdown of everything that actually matters 👇 🔹 Core Architecture (MVT) Django follows the Model-View-Template pattern: • Model → Database structure & data handling • View → Business logic & request/response handling • Template → Frontend rendering (HTML + dynamic data) 🔹 URL Routing Maps user requests to specific views using urls.py — clean and scalable routing system. 🔹 ORM (Object Relational Mapping) No need for raw SQL. Interact with databases using Python: • Query, filter, update seamlessly • Database-agnostic (SQLite, PostgreSQL, MySQL) 🔹 Authentication & Authorization Built-in system for: • User login/logout • Password hashing • Permissions & roles 🔹 Admin Panel (Game Changer) Auto-generated admin dashboard to manage data without writing extra code. 🔹 Forms Handling Secure form processing with validation, CSRF protection, and clean data handling. 🔹 Middleware Hooks into request/response cycle: • Authentication • Logging • Security layers 🔹 REST API Development With Django REST Framework: • Build scalable APIs • Serialization & validation • Token/JWT authentication 🔹 Security Features 🔐 Django protects against: • SQL Injection • XSS (Cross-Site Scripting) • CSRF attacks • Clickjacking 🔹 Scalability & Performance • Works with caching (Redis, Memcached) • Supports asynchronous views • Easy integration with cloud & containers 🔹 File Handling Upload & manage media files (images, PDFs, etc.) easily. 🔹 Signals Trigger actions automatically (e.g., after saving a model). 🔹 Session & Cookies Maintain user state across requests. 💡 Why Django? ✔ Rapid development ✔ Clean & maintainable code ✔ Batteries-included framework ✔ Trusted by companies like Instagram & Pinterest 🔥 Whether you're building a startup product, REST API, or full-stack app — Django gives you everything out of the box. #Django #BackendDevelopment #Python #WebDevelopment #SoftwareEngineering #FullStack #APIs

Understanding Django concepts with practical usage is really a worth try. Once you started working on a Django web app project, you will definitely face most of these concepts. I suggest to work on projects, you might be getting lots of bugs and errors. Even though once you solve it and progress ahead. You found happiness and satisfaction. That's the best way of learning something new.
