-
-**Type**: Django 5.2 web app (lab inventory)  
-**Python**: 3.13 | **DB**: SQLite (dev) | **Env**: `.venv/`
-
-## Essential Commands
-
-```bash
-# Activate venv first
-source .venv/bin/activate
-
-# Dev server
-python manage.py runserver              # localhost:8000
-python manage.py runserver 0.0.0.0:8000 # all interfaces
-
-# Database
-python manage.py makemigrations boxes   # after model changes
-python manage.py migrate
-python manage.py showmigrations
-
-# Testing
-python manage.py test                    # all
-python manage.py test boxes              # app only
-python manage.py test boxes.tests.BoxModelTests.test_method  # specific
-
-# Custom commands
-python manage.py create_default_users    # admin/admin123, staff/staff123, viewer/viewer123
-python manage.py clean_orphaned_files --dry-run
-python manage.py clean_orphaned_images --dry-run
-python manage.py collectstatic           # after CSS changes
-```
-
-## Critical Rules
-
-1. **NEVER commit/push without explicit permission** - wait for user to say "commit and push"
-2. Use `get_object_or_404()` not bare `.get()` for model lookups
-3. Run `makemigrations` then `migrate` after any model change
-4. Default users: `admin/admin123` (superuser), `staff/staff123`, `viewer/viewer123`
-
-## Data Model
-
- **BoxType** → Box (1:N, PROTECT)
- **Box** → Thing (1:N, PROTECT) — Box.pk is CharField(max=10)
- **Facet** → Tag (1:N, CASCADE) — Facet.cardinality: single/multiple
- **Thing** ↔ Tag (M2M)
- **Thing** → ThingFile, ThingLink (1:N, CASCADE)
-
-## Deployment (when instructed)
-
-**Full deploy**: bump both versions in `argocd/deployment.yaml` (+0.001), then:
-```bash
-cp data/db.sqlite3 data-loader/preload.sqlite3
-```
-
-**Partial deploy**: bump main container only, skip DB copy.
-
-## Key Directories
-
- `boxes/` — main app (models, views, forms, templates)
- `labhelper/` — project settings, base template
- `argocd/` — Kubernetes manifests for production
- `data-loader/` — init container with preloaded DB
-
-## Gotchas
-
- Template base: `labhelper/templates/base.html`
- App templates: `boxes/templates/boxes/`
- Box ID is CharField (e.g., "A1-001"), not auto-increment
- Views use `conditional_login_required` - bypasses login for IPs in `ALLOWED_CIDR_NETS` env var
- Markdown via `{{ text|render_markdown }}` (sanitized with bleach)
- Third-party: django-mptt, sorl-thumbnail, bleach, markdown

-```
-
-### Production
-
-```bash
-gunicorn labhelper.wsgi:application     # Run with Gunicorn
-```
-
-## Code Style Guidelines
-
-### Python Style
-
- Follow PEP 8 conventions
- Use 4-space indentation (no tabs)
- Maximum line length: 79 characters (PEP 8 standard)
- Use single quotes for strings: `'string'`
- Use double quotes for docstrings: `"""Docstring."""`
-
-### Import Order
-
-Organize imports in this order, with blank lines between groups:
-
-```python
-# 1. Standard library imports
-import os
-import sys
-from pathlib import Path
-
-# 2. Django imports
-from django.db import models
-from django.contrib import admin
-from django.shortcuts import render, redirect
-from django.http import HttpResponse, JsonResponse
-
-# 3. Third-party imports
-import requests
-from markdown import markdown
-
-# 4. Local application imports
-from .models import MyModel
-from .forms import MyForm
-```
-
-### Naming Conventions
-
-| Type | Convention | Example |
-|------|------------|---------|
-| Modules | lowercase_with_underscores | `user_profile.py` |
-| Classes | PascalCase | `UserProfile` |
-| Functions | lowercase_with_underscores | `get_user_data()` |
-| Constants | UPPERCASE_WITH_UNDERSCORES | `MAX_CONNECTIONS` |
-| Variables | lowercase_with_underscores | `user_count` |
-| Django Models | PascalCase (singular) | `Box`, `UserProfile` |
-| Django Apps | lowercase (short) | `boxes`, `users` |
-
-### Django-Specific Conventions
-
-**Models:**
-```python
-from django.db import models
-
-class Box(models.Model):
-    """A storage box in the lab."""
-    
-    name = models.CharField(max_length=255)
-    created_at = models.DateTimeField(auto_now_add=True)
-    updated_at = models.DateTimeField(auto_now=True)
-
-    class Meta:
-        verbose_name_plural = 'boxes'
-        ordering = ['-created_at']
-
-    def __str__(self):
-        return self.name
-```
-
-**Views:**
-```python
-from django.shortcuts import render, get_object_or_404
-from django.http import Http404
-
-def box_detail(request, box_id):
-    """Display details for a specific box."""
-    box = get_object_or_404(Box, pk=box_id)
-    return render(request, 'boxes/detail.html', {'box': box})
-```
-
-### Error Handling
-
-```python
-# Use specific exceptions
-try:
-    result = some_operation()
-except SpecificError as exc:
-    raise CustomError('Descriptive message') from exc
-
-# Django: Use get_object_or_404 for model lookups
-box = get_object_or_404(Box, pk=box_id)
-
-# Log errors appropriately
-import logging
-logger = logging.getLogger(__name__)
-logger.error('Error message: %s', error_detail)
-```
-
-### Type Hints (Recommended)
-
-```python
-from typing import Optional
-from django.http import HttpRequest, HttpResponse
-
-def get_box(request: HttpRequest, box_id: int) -> HttpResponse:
-    """Retrieve a box by ID."""
-    ...
-```

-
-## Available Django Extensions
-
-The project includes these pre-installed packages:
-
- **django-mptt**: Tree structures (categories, hierarchies)
- **django-mptt-admin**: Admin interface for MPTT models
- **django-admin-sortable2**: Drag-and-drop ordering in admin
- **django-nested-admin**: Nested inline forms in admin
- **django-nested-inline**: Additional nested inline support
- **django-revproxy**: Reverse proxy functionality
-
-## Testing Guidelines
-
- Use `django.test.TestCase` for database tests
- Use `django.test.SimpleTestCase` for tests without database
- Name test files `test_*.py` or `*_tests.py`
- Name test methods `test_*`
- Use descriptive test method names
-
-```python
-from django.test import TestCase
-from .models import Box
-
-class BoxModelTests(TestCase):
-    """Tests for the Box model."""
-
-    def setUp(self):
-        """Set up test fixtures."""
-        self.box = Box.objects.create(name='Test Box')
-
-    def test_box_str_returns_name(self):
-        """Box __str__ should return the box name."""
-        self.assertEqual(str(self.box), 'Test Box')
-```
-
-## Files to Never Commit
-
-Per `.gitignore`:
- `__pycache__/`, `*.pyc` - Python bytecode
- `.venv/` - Virtual environment
- `.env` - Environment variables
- `data/db.sqlite3` - Database file
- `keys/` - Secret keys
-
-## Common Pitfalls
-
-1. **Always activate venv**: `source .venv/bin/activate`
-2. **Run migrations after model changes**: `makemigrations` then `migrate`
-3. **Add new apps to INSTALLED_APPS** in `settings.py`
-4. **Use get_object_or_404** instead of bare `.get()` calls
-5. **Never commit SECRET_KEY** - use environment variables in production
-
-## Deployment Commands
-
-### Prepare a Full Deployment
-
-When instructed to "Prepare a full deployment", perform the following steps:
-
-1. **Bump container versions**: In `argocd/deployment.yaml`, increment the version numbers by 0.001 for both containers:
-   - `labhelper-data-loader` (initContainer)
-   - `labhelper` (main container)
-
-2. **Copy database**: Copy the current development database to the data-loader preload location:
-   ```bash
-   cp data/db.sqlite3 data-loader/preload.sqlite3
-   ```
-
-### Prepare a Partial Deployment
-
-When instructed to "Prepare a partial deployment", perform the following step:
-
-1. **Bump main container version only**: In `argocd/deployment.yaml`, increment the version number by 0.001 for the main container only:
-   - `labhelper` (main container)
-
-Do NOT bump the data-loader version or copy the database.

-# LabHelper
-
-A Django web app for keeping track of what's in the physical storage boxes in a lab
-or workshop. Boxes hold *things*, things are described, pictured, tagged, and linked
-to datasheets and resources, and everything is searchable from one box. Authentication
-is handled by Keycloak (OIDC), and the app is packaged for Kubernetes deployment via
-ArgoCD.
-
-## Features
-
- **Boxes & box types** — define reusable box types (with physical dimensions) and
-  create boxes of those types. Box IDs are human-chosen strings (e.g. `A1-001`), not
-  auto-increment numbers.
- **Things** — items stored in a box, each with a name, Markdown description, picture,
-  file attachments (datasheets, etc.), and hyperlinks.
- **Faceted tagging** — organise things by facets (e.g. *Category*, *Priority*). Each
-  facet is single- or multi-valued and has its own colour. Tags belong to a facet.
- **Search** — live AJAX search across names, descriptions, tags, files, and links.
-  Supports `Facet:Value` queries (e.g. `Category:Resistors`).
- **Resources view** — a flat list of every file and link across all things.
- **"Fix me" view** — find things missing a tag for a given facet and bulk-tag them.
- **Bulk add** — add many things to a box at once via a formset.
- **SSO** — Keycloak/OIDC login with automatic Django group and `is_staff` mapping.
-
-## Tech stack
-
-| Area | Choice |
-|------|--------|
-| Framework | Django 5.2 (Python 3.13/3.14) |
-| Database | SQLite (file-backed, persisted on a PVC in production) |
-| Auth | `mozilla-django-oidc` against Keycloak |
-| Static files | WhiteNoise (compressed manifest storage) |
-| Images | Pillow + `sorl-thumbnail` |
-| Markdown | `markdown` rendered then sanitised with `bleach` |
-| Tree data | `django-mptt` (facet/type hierarchies) |
-| WSGI server | Gunicorn (3 workers) |
-| Deployment | Docker image → Gitea registry → ArgoCD → Kubernetes (Traefik ingress) |
-
-## Data model
-
-```
-BoxType ──1:N──> Box ──1:N──> Thing ──M:N──> Tag <──1:N── Facet
-                                 │
-                                 ├──1:N──> ThingFile
-                                 └──1:N──> ThingLink
-```
-
- `BoxType → Box` and `Box → Thing` use `PROTECT` (you can't delete a box type still
-  in use, or a box that still holds things).
- `Facet → Tag` and `Thing → ThingFile`/`ThingLink` use `CASCADE`.
- `Box.id` is a `CharField(max_length=10)` primary key.
- `Facet.cardinality` is `single` (0..1 tag per thing) or `multiple` (0..n).
-
-## Local development
-
-```bash
-# 1. Activate the virtualenv
-source .venv/bin/activate
-
-# 2. Apply migrations (SQLite DB lives at data/db.sqlite3)
-python manage.py migrate
-
-# 3. Run the dev server
-python manage.py runserver              # http://localhost:8000
-python manage.py runserver 0.0.0.0:8000 # all interfaces
-```
-
-For local development you'll typically want `DEBUG=True` (the default) and to reach
-the app from an IP inside `ALLOWED_CIDR_NETS`, which bypasses the login requirement
-(see [Authentication](#authentication)). Otherwise you need a working Keycloak realm
-configured through the environment variables below.
-
-### Common commands
-
-```bash
-# Database
-python manage.py makemigrations boxes   # after editing boxes/models.py
-python manage.py migrate
-python manage.py showmigrations
-
-# Tests
-python manage.py test                   # everything
-python manage.py test boxes             # the boxes app only
-
-# Static files (after CSS changes)
-python manage.py collectstatic
-
-# Custom management commands
-python manage.py list_things            # print all things with box IDs
-python manage.py clean_orphaned_files --dry-run    # remove unreferenced files
-python manage.py clean_orphaned_images --dry-run   # remove unreferenced images
-```
-
-## Configuration
-
-All configuration is read from environment variables (see `labhelper/settings.py`).
-Sensible defaults exist for local development; production values come from the
-Kubernetes ConfigMap (`argocd/configmap.yaml`) and Secret.
-
-| Variable | Purpose | Default |
-|----------|---------|---------|
-| `DJANGO_SECRET_KEY` | Django secret key | dev key (do **not** use in prod) |
-| `DEBUG` | Debug mode | `True` |
-| `ALLOWED_HOSTS` | Comma-separated allowed hosts | `*` |
-| `ALLOWED_CIDR_NETS` | CIDR ranges that skip login | `10.0.0.0/16,192.168.0.0/16` |
-| `CSRF_TRUSTED_ORIGINS` | Trusted origins for CSRF | prod URL + `127.0.0.1:8000` |
-| `STATIC_URL` / `MEDIA_URL` | Static/media URL prefixes | `/static/` / `/media/` |
-| `TIME_ZONE`, `LANGUAGE_CODE`, `USE_I18N`, `USE_TZ` | Localisation | UTC / en-us / True |
-| `LOGIN_URL` | Where unauthenticated users go | `oidc_authentication_init` |
-| `LOGIN_REDIRECT_URL` / `LOGOUT_REDIRECT_URL` | Post-auth redirects | `index` / `login` |
-| `OIDC_OP_BASE_URL` | Keycloak realm URL (endpoints derived from it) | — |
-| `OIDC_RP_CLIENT_ID` / `OIDC_RP_CLIENT_SECRET` | OIDC client credentials | — |
-| `GUNICORN_OPTS` | Extra gunicorn flags | — |
-
-`OIDC_OP_BASE_URL` should be the realm URL, e.g.
-`https://sso.example.com/realms/homelab`. The individual OIDC endpoints
-(auth, token, userinfo, JWKS, logout) are derived from it automatically but can each
-be overridden with their own `OIDC_OP_*_ENDPOINT` variable.
-
-## Authentication
-
-Login is handled by Keycloak through `mozilla-django-oidc`. Two access paths exist:
-
-1. **OIDC login** — the normal path. `KeycloakOIDCBackend`
-   (`labhelper/auth_backend.py`) syncs the user's name, `is_staff` flag, and Django
-   group membership from Keycloak group claims on every login. The mapping:
-
-   | Keycloak group | Django group | `is_staff` |
-   |----------------|--------------|-----------|
-   | `LabHelper Administrators` | `LabHelper Administrators` | yes |
-   | `LabHelper Staff` | `LabHelper Staff` | no |
-   | `LabHelper Viewers` | `LabHelper Viewers` | no |
-
-2. **Trusted networks** — every view is wrapped in
-   `conditional_login_required` (`boxes/decorators.py`), which **skips** authentication
-   entirely for clients whose IP falls within `ALLOWED_CIDR_NETS`. This is what lets
-   the app run open on a trusted LAN while still requiring SSO from outside.
-
-The `ModelBackend` is retained as a fallback so the Django admin
-(`/admin/`) remains reachable for emergency access.
-
-See `Keycloak-installation.md` for notes on setting up the realm, client, and groups.
-
-## Deployment
-
-The app ships as two container images to a Gitea registry
-(`git.baumann.gr/adebaumann/…`) and is reconciled onto Kubernetes by ArgoCD from the
-manifests in `argocd/`:
-
- **`web`** — the Django app (built from the root `Dockerfile`, served by gunicorn).
- **`loader`** — an init container (`data-loader/`) that seeds the SQLite database from
-  a preloaded copy on first boot, then preserves any existing DB on the PVC.
-
-Images are **not** built on every push. The Gitea Actions workflow
-(`.gitea/workflows/build-containers-on-demand.yml`) triggers only when
-`argocd/deployment.yaml`, the `Dockerfile`, or `data-loader/**` change, reads the exact
-image tag out of the deployment manifest, and builds + pushes only if that tag isn't
-already in the registry. So **deploying = bumping the image tag** in the manifest.
-
-Two helper scripts prepare a release:
-
-```bash
-# Full deploy: bump BOTH image versions (+0.001) and snapshot the DB into the loader
-./scripts/full_deploy.sh
-
-# Partial deploy: bump only the main web container (no DB snapshot)
-./scripts/partial_deploy.sh
-```
-
-After running a script, commit and push the changed manifests — Gitea Actions builds
-the images and ArgoCD rolls them out.
-
-### Kubernetes resources (`argocd/`)
-
-| File | Resource |
-|------|----------|
-| `deployment.yaml` | Deployment (web + loader init container) and Service |
-| `ingress.yaml` | Traefik Ingress for `labhelper.adebaumann.com` |
-| `configmap.yaml` | Non-secret environment configuration |
-| `001_pvc.yaml` | PersistentVolumeClaim for the SQLite DB and media |
-| `nfs-pv.yaml` | NFS-backed PersistentVolume |
-
-Secrets (`DJANGO_SECRET_KEY`, `oidc-client-secret`) are supplied via a Kubernetes
-Secret; see `k8s-templates/secret.yaml` and `scripts/deploy_secret.sh`. Liveness and
-readiness probes hit the `/health/` endpoint.

-## Notes & gotchas
-
- Templates live in `labhelper/templates/` (base) and `boxes/templates/boxes/` (app).
- Descriptions are Markdown, rendered via a `render_markdown` filter and sanitised with
-  `bleach` — don't trust raw HTML from descriptions.
- Media files are served by Django in all environments (WhiteNoise handles static).
- Uploaded pictures are renamed to `things/<thing-id>-<slug>.<ext>` after the thing gets
-  a primary key (see `Thing.save`).
- Deleting a thing also deletes its picture and attached files from disk.
