Currently Learning & Building with Django REST Framework I am currently working on building REST APIs using Django REST Framework as part of my learning journey in backend development. How API works with Django: • Client (browser/mobile) sends a request • API acts as a middle layer and forwards the request • Django backend processes the request using models • Data is fetched from the database • API converts the data into JSON format • JSON response is sent back to the client This helped me understand how APIs act as a bridge between frontend and backend in real-world applications. Sharing a simple visual (3D diagram) to explain the API flow in Django. #Django #RESTAPI #Python #BackendDevelopment #LearningJourney #WebDevelopment

Django vs. FastAPI: Which Python framework should you choose for your next project? The Python web landscape is no longer a one-horse race. While Django has long been the 'batteries-included' gold standard for perfectionists with deadlines, FastAPI has rapidly become the go-to for high-performance, asynchronous APIs. Django provides a structured, monolithic environment with a built-in ORM and Admin interface, perfect for rapid full-stack development. FastAPI, built on Starlette and Pydantic, offers raw speed and automatic documentation that rivals Node.js and Go. Are you building a complex enterprise application or a high-concurrency microservice? The choice defines your entire architecture and developer experience.

Most Django middleware is written with one method. Django actually offers five. Here's what Django does: 1. Django doesn't call middleware as a single function. It calls specific hooks at specific moments in the request lifecycle. 2. Each hook with a different purpose, different data available and different consequences for what gets returned. a. process_request(request): - Fires after the request object is built - before URL resolution. - The view hasn't been identified yet. Return a response here and URL resolution never happens, view never runs. - Use for: blanket request rejection, IP blocking, early authentication checks. b. process_view(request, view_func, view_args, view_kwargs): - Fires after URL resolution - the view function is now known, but not yet called. - Full access to the view function itself and its arguments. Return a response here and view never executes, but process_response still runs on the way out. - Use for: view-specific logic, caching c. process_response(request, response): - Fires after the view returns - always, regardless of what happened upstream. - Must always return a response, returning None here raises an exception. - Use for: modifying headers, injecting content, logging response metadata. d. process_exception(request, exception): - Fires only when the view raises an unhandled exception.  - Return a response and exception is handled, process_response runs normally. - Return None and exception propagates to the next middleware's process_exception. Knowing which hook to use is the difference between middleware that works and middleware that works until it doesn't. Have you ever had a middleware silently break something downstream? #Python #Django #BackendDevelopment #SoftwareEngineering

💡Django tip Fix Race Conditions in Django: #python #django #sql #api Every high-traffic store, ticketing platform, or booking system has this silent killer: two users hit "Buy" at the same millisecond, both see stock = 1, both complete — now you've sold something you don't have. select_for_update() locks the row at the database level so only one transaction wins. Important notes on the code 1 nowait=True — fails immediately under contention instead of silently queuing, giving the API a fast, explicit error response 2 save(update_fields=['stock']) — writes only the changed column, not the entire row 3 Custom exceptions (OutOfStockError, InsufficientQuantityError) — clean separation between "no stock at all" vs "not enough stock" 4 Logic extracted into a services.py layer — keeps views thin and the purchase logic fully testable in isolation OutOfStockError Triggered when stock == 0 — the product has absolutely nothing left. No amount of reducing quantity will help. InsufficientQuantityError Triggered when stock > 0 but less than what the user requested — there's some stock, just not enough for this order. #tip #tips #tipoftheday
