This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

What this is

ClubManager is a sport club management app + public website, built on Django 6.0 (Python 3.14+). As of 2026-07-11 it is designed as a multi-tenant platform (row-based / shared-schema): one deployment serves many clubs, with Club as the tenant root. Every club-owned model carries a club FK (via ClubScopedModel); User is the only global model. This reverses the project's earlier single-club stance — treat older "single-club / no club_id tenancy" notes (in git history or memory) as obsolete.

ARCHITECTURE.md at the repo root is the authoritative model & domain design — the tenancy mechanics, the RBAC design, and per-app model sketches all live there. Consult and update it when adding domain models.

The repo is an early build: authentication and club apps exist (User, Member, Family, FamilyMembership, Club, ClubMembership); the remaining domain apps and the tenancy plumbing (clubmanager/tenancy.py, tenant middleware, ClubScopedModel upgrade) are planned, not yet on disk. Verify against the actual tree before assuming a module exists.

Commands

Dependencies and the virtualenv are managed with uv (pyproject.toml at repo root, uv.lock committed). Run Django/tools through uv run so the project venv is used.

uv sync                              # install deps (incl. dev group) into .venv
uv run python manage.py runserver    # dev server
uv run python manage.py migrate      # apply migrations
uv run python manage.py makemigrations
uv run python manage.py createsuperuser
uv run python manage.py shell

uv run python manage.py test                     # run all tests (Django test runner)
uv run python manage.py test <app>               # one app
uv run python manage.py test <app>.tests.<Case>  # one TestCase
uv run python manage.py test <app>.tests.<Case>.<method>  # one test

uv run ruff check .                  # lint
uv run ruff check --fix .            # lint + autofix
uv run ruff format .                 # format

Configuration

Settings live in a single clubmanager/settings.py and read from the environment via python-decouple (config(...)), with a local .env file for dev. Key vars: DJANGO_SECRET_KEY (required), DJANGO_DEBUG, DJANGO_ALLOWED_HOSTS, DJANGO_CSRF_TRUSTED_ORIGINS, DJANGO_DATABASE_URL, DJANGO_TIME_ZONE.

The database is configured through a single DJANGO_DATABASE_URL (parsed by dj-database-url), defaulting to sqlite:///db.sqlite3 for dev; production is intended to point at PostgreSQL via that URL. Don't hardcode DB settings — go through the env var.

Planned architecture

ARCHITECTURE.md is the source of truth for the model design; this is a summary. The app decomposition (authentication, members, club, teams, events, news, pages, home, formbuilder, shop, search) has grown past the original pyproject.toml isort known-first-party list — add new labels there as apps land. Note the accounts app was split into authentication (global login) + club, and people models (Member, Family) are being moved into a dedicated members app.

Domain notes (drive modeling decisions):

• Multi-tenancy is the cross-cutting rule. Club is the tenant root; club-owned models inherit ClubScopedModel (a club FK). Scope every query to the current tenant (.for_club() / .current()); previously-global uniqueness (slugs, season names, invoice numbers) becomes unique per club. Only User is global. See ARCHITECTURE.md §2.4.
• Season is the central organizing concept, per club. Team rosters, events, and attendance are season-scoped — model them with a FK to a season, not as global state.
• A Member (a person within one club) can play on one or more Teams, each with a position + jersey number (unique within a team), always tied to a specific season.
• RBAC is per-club and service-layer (not django-guardian, not global Django groups): ClubRole rows (MEMBER / EDITOR / TREASURER / BOARD) plus object-scoped roles (coach via StaffAssignment, parent via FamilyMembership), all decisions routed through an access service. Django's own permissions are used only for the platform-admin layer.
• Later modules: formbuilder (admin-defined dynamic forms → normalized answers → reporting) and shop (cart → order → payment → HTML→PDF invoices via WeasyPrint), with season-scoped ClubMembership tracking sign-up + fee status per season.

Conventions

• Ruff config anticipates a Wagtail-style codebase (DJ Django rules; RUF012/RUF005 ignored for framework idioms; line-length = 250). Migrations are excluded from linting — don't hand-edit them to satisfy ruff.
• Settings files are exempt from F403/F405/E501 (star imports allowed) under clubmanager/settings/* — note the config expects a settings package, though the current code is a single settings.py. If you split settings, match that path.
