Learn web development with step-by-step guides
From beginner to advanced — Django, Python, REST APIs, JavaScript, Bootstrap, and more
Turn the Django admin into a real operations console: powerful change lists, query optimization, bulk actions, inline formsets, autocomplete, custom filters and views, dashboards, object-level permissions — and how to secure and speed up the admin in production.
Turn Django into a spatial framework with GeoDjango and PostGIS: geometry fields, SRIDs, spatial lookups, nearest-neighbor distance queries, importing geographic datasets, GiST indexing, and serving maps — plus the coordinate-system pitfalls to avoid.
Move Django file storage off local disk: django-storages with S3-compatible object storage, private files via signed URLs, direct browser uploads with presigned POST, streaming large files, async image pipelines, and CDN + security pitfalls.
When Postgres full-text search isn't enough: integrating Elasticsearch/OpenSearch with Django — modelling documents, keeping the index in sync, tuning relevance with boosts and fuzziness, facets, and zero-downtime reindexing with aliases.
A production guide to Stripe in Django: the object model, Checkout vs PaymentIntents, subscription lifecycles, why webhooks are the source of truth, idempotency keys, and Strong Customer Authentication — without card data touching your server.
Async Django done right: the ASGI model, async views and the async ORM, safely mixing sync and async with sync_to_async, serving under Uvicorn, and the decision of when concurrency actually pays off.
Stop guessing why your app is slow. Profile a live Django process without restarting it using py-spy, trace per-request queries and timings with django-silk, read flame graphs, and turn findings into concrete fixes.
Move from a slow, brittle test suite to a fast, trustworthy one. Master pytest-django fixtures, generate data with factory_boy, find edge cases automatically with property-based testing, and measure real coverage with mutation testing.
Lock down server-to-server and public APIs. Layer per-client rate limiting, verify request integrity with HMAC signatures, defeat replay attacks with nonces and timestamps, and authenticate machines with mutual TLS.
Kill the password. Implement WebAuthn/passkeys in Django end to end — registration and authentication ceremonies, public-key credential storage, the security model that makes passkeys phishing-resistant, and a sane fallback strategy.
Ship to production continuously without big-bang risk. Build a feature-flag layer in Django, roll features out to a percentage of users, run A/B experiments, and add instant kill switches for when something goes wrong.
Decouple your Django services with events instead of synchronous calls. Choose between Redis Streams and Kafka, guarantee delivery with the transactional outbox pattern, and build idempotent consumers that survive retries.
