Avoid common Django mistakes — QuerySet evaluation, N+1 queries, migration conflicts, and ORM traps.
Avoid common Django mistakes — QuerySet evaluation, N+1 queries, migration conflicts, and ORM traps.
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.

QuerySets are lazy — iterating twice hits DB twice, use list() to cache select_related for FK/O2O, prefetch_related for M2M — or N+1 queries update() skips save() — no signals fire, no auto_now update F() for atomic updates — F('count') + 1 avoids race conditions get() raises DoesNotExist or MultipleObjectsReturned — use filter().first() for safe DEBUG=False requires ALLOWED_HOSTS — 400 Bad Request without it Forms need {% csrf_token %} — or 403 Forbidden on POST auto_now can't be overridden — use default=timezone.now if need manual set exclude(field=None) excludes NULL — use filter(field__isnull=True) for NULL Circular imports in models — use string reference: ForeignKey('app.Model') transaction.atomic() doesn't catch exceptions — errors still propagate sync_to_async for ORM in async views — ORM is sync-only
Long-tail utilities that do not fit the current primary taxonomy cleanly.
