django-filter provides declarative filtering for DRF viewsets. I define a FilterSet class with fields to filter on. The DjangoFilterBackend integrates seamlessly with DRF. I use CharFilter, NumberFilter, DateFilter etc. for different field types. Look

API versioning via middleware provides clean URL routing. I extract version from Accept header or URL prefix and set it on the request object. Views can check request.api_version to return appropriate responses. For breaking changes, I maintain separa

For batch operations, Stimulus can manage the UI state (select all, indeterminate checkbox) while Turbo submits a regular form. This keeps the server in charge of authorization and the UI simple.

The clean() method validates model instances before saving. I raise ValidationError for invalid data. This runs on form submission and can be called explicitly with full_clean(). I validate cross-field constraints that can't be expressed as field vali

JSONField stores structured data without creating separate tables. I use it for settings, metadata, or varying attributes. Django provides database-level JSON operations via lookups like __contains, __has_key. For PostgreSQL, I get native JSON operato

Copying code is a core interaction in a snippets app, and it needs to work reliably across browsers. The modern API is navigator.clipboard.writeText, but it requires HTTPS and permissions in some contexts. I try it first, and if it fails I fall back t

When I want ‘real time’ updates without the operational overhead of WebSockets, I reach for Server-Sent Events (SSE). It’s just streaming HTTP, so it behaves well behind proxies and is easy to reason about. I set the right headers (Content-Type: text/

Bulk operations reduce database round-trips dramatically. I use bulk_create() for inserting many objects at once, bulk_update() for updates, and update() for queryset-level updates. These bypass save() methods and signals for speed. For large datasets

When downstream systems degrade, jobs pile up and amplify outages. Add a simple “queue depth guard” so non-critical jobs skip or reschedule instead of making the backlog worse.

The first time a CSV import OOM’d a production process, I stopped trusting ‘just read it into memory’. Now I stream the upload to disk (or S3), stream-parse rows, and batch inserts into the DB. The win is that memory usage stays flat, even when the fi

When forms live inside a Turbo Frame (modal or inline edit), validation needs to feel immediate without a full-page refresh. I render the form inside a frame with an ID like post_form. On submit, create/update returns status: :unprocessable_entity and

When replacing DOM chunks, morphing reduces flicker and preserves focus/selection. If you enable morphing, prefer server-rendered HTML that’s stable and keyed. It’s a subtle but meaningful quality improvement.
