isik
Everyday Python utilities, and a set of Django and Django REST Framework building blocks: base models with history tracking, per-host feedback and tag models attached without hand-written migrations, scoped permissions, serializer and viewset mixins, and HTTP exceptions you can raise from anywhere.
Install
pip install isik # isik.common only - no dependencies
pip install isik[django] # isik.django.apps, isik.django.http_exceptions
pip install isik[drf] # isik.django.drf - brings the django extra with it
pip install isik[celery] # isik.django.celery - brings the django extra with it
pip install isik[all] # everything, sentry/tiptap/templated_fields included
Requires Python 3.11+. The django and drf extras assume PostgreSQL: BaseModel's timestamps
and history tracking run on database triggers
(django-pgtrigger,
django-pghistory), so add pgtrigger and
pghistory to INSTALLED_APPS. Bring your own database driver (psycopg or psycopg2); isik doesn't
choose one for you.
Documentation
The full index is docs/INDEX.md.
- isik.common - caching, concurrency, error handling, functional helpers, typed settings from environment variables
- isik.django.apps -
BaseModel, history tracking, and thevotes()/comments()/notes()/bookmarks()/tags()makers - Idempotency keys -
Idempotency-Keyon DRF views: a retry replays the first response instead of doing the work twice - isik.django.drf - permissions
(
guarding,django_permission, ...), request policies on any view, serializer and viewset mixins, filters, pagination - isik.django.celery - a task base whose history rows name whoever caused the task, not nobody
- isik.django.http_exceptions - raise an HTTP status directly instead of threading responses back up the call stack
- isik.sentry - Sentry-reporting exception suppression
- Translations - every user-facing string is translatable, through Django's catalogs or stdlib gettext
Plain Python, and worth knowing about in a Django project
A Django project's imports all start with isik.django, so isik.common.utils is easy to never
see. It needs no Django and these come up in Django code constantly:
first_of(iterable, default=None, pred=None)/not_none- the first item, or the first one matching a predicate, without anext(...)and aStopIterationto handle.with_attrs(**attrs)- set attributes on a function as a decorator (short_description,booleanon an admin method).returns(value)/raises(exception)/noop/identity- small callables for defaults and hooks.Exemption- an opt-out that names the rule it skips and says why, held to a minimum length and listed by rule (manage.py exemptions):NoHelpText(reason="why").TransformExceptions/SuppressAndRun- turn one exception into another, or run something when one is swallowed.
See isik.common for all of it.
