 # Fehlersuche: Geplante Ausleihen werden nicht automatisch aktiviert
 ## 🔍 Mögliche Ursachen
 ### 1. **Termin wurde für falsches Datum erstellt**
 Die meisten Probleme entstehen, weil der Termin für ein **falsches Datum** (z.B. morgen statt heute) erstellt wurde.
 ### 2. **Scheduler läuft nicht**
 Der automatische Scheduler kann deaktiviert sein oder nicht starten.
 ### 3. **Zeitzonen-Problem**
 Die Startzeit kann in einer anderen Zeitzone gespeichert sein als erwartet.
 ---
 ## ✅ SOFORT-FIX: Manuell aktivieren
 Falls du eine geplante Ausleihe sofort aktivieren möchtest, nutze diesen Befehl auf dem Server:
 ```bash
 docker exec inventarsystem-mongodb mongosh --eval "
 db.ausleihungen.updateOne(
  {_id: ObjectId('BOOKING_ID_HIER')},
  {\$set: {Status: 'active', LastUpdated: new Date()}}
 )" Inventarsystem
 ```
 Ersetze `BOOKING_ID_HIER` mit der ID deiner Ausleihe.
 ---
 ## 🔧 DEBUG: Alle geplanten Ausleihen anschauen
 Führe auf deinem Server aus:
 ```bash
 docker exec inventarsystem-mongodb mongosh --eval "
 db.ausleihungen.find({Status: 'planned'}).pretty()
 " Inventarsystem
 ```
 Das zeigt dir:
 - **Start**: Das gespeicherte Startdatum/Uhrzeit
 - **Periode**: Die Schulstunde (falls verwendet)
 - **Erstellungs-Zeit vs. aktuelle Zeit**: Vergleich
 ---
 ## 🎯 PROBLEM 1: Falsches Datum beim Erstellen
 **Symptom**: Start-Zeit ist in der Zukunft (z.B. morgen statt heute)
 **Lösung**: 
 1. In der Kalender-Ansicht das **richtige Datum** auswählen
 2. Die **aktuelle Uhrzeit** für den Beginn nutzen (nicht eine zukünftige Zeit)
 3. Für Schulstunden: Stelle sicher die **heutige Schulstunde** zu wählen
 ---
 ## 🎯 PROBLEM 2: Scheduler läuft nicht
 **Symptom**: Keine Logs über Termin-Aktivierungen
 **Überprüfung**:
 ```bash
 # 1. Container-Logs anschauen
 docker logs inventarsystem-app | grep -i "scheduler\|appointment\|status update"
 # 2. Scheduler ist aktiviert?
 docker exec inventarsystem-app python3 -c "
 import sys
 sys.path.insert(0, '/app/Web')
 import settings as cfg
 print(f'Scheduler aktiviert: {cfg.SCHEDULER_ENABLED}')
 print(f'Scheduler Intervall: {cfg.SCHEDULER_INTERVAL_MIN} Minuten')
 "
 ```
 **Lösung wenn deaktiviert**:
 - In `config.json` ändern:
  ```json
  "scheduler": {
    "enabled": true,
    "interval_minutes": 1
  }
  ```
 - Container neu starten: `docker-compose restart app`
 ---
 ## 🎯 PROBLEM 3: Startzeit als nur-Zeit (kein Datum)
 **Symptom**: Start-Zeit zeigt nur "13:30" ohne Datum
 **Überprüfung**: In der Datenbank nach `{Start: {$type: "string"}}` suchen statt datetime
 **Lösung**: Die Ausleihe muss mit einem vollständigen Datum+Uhrzeit erstellt werden.
 ---
 ## 🚀 AUTOMATISCHE AKTIVIERUNG TESTEN
 Nach dem Fix: Erstelle eine Ausleihe für:
 - **Heute** (das aktuelle Datum)
 - **Schulstunde 7** (13:30-14:15)
 - Startzeitpunkt sollte **jetzt oder in 1 Minute** sein
 Warte 2 Minuten. Der Status sollte von `planned` zu `active` wechseln.
 ---
 ## 📊 SCHEDULER STATUS ÜBERPRÜFEN
 ```bash
 # Zeige die letzten 50 Log-Zeilen
 docker logs --tail 50 inventarsystem-app | tail -20
 # Suche nach "Appointment status update"
 docker logs inventarsystem-app 2>/dev/null | grep -i "Appointment status" | tail -5
 ```
 Erwartete Log-Ausgabe:
 ```
 Appointment status update finished: X changed (Y active, Z completed)
 ```
 ---
 ## 🔍 DETAILLIERTE DEBUG-INFOS
 Wenn obiges nicht funktioniert, führe dies aus:
 ```bash
 docker exec inventarsystem-app python3 -c "
 from pymongo import MongoClient
 import datetime
 client = MongoClient('mongodb', 27017)
 db = client['Inventarsystem']
 aus = db['ausleihungen']
 print('=== GEPLANTE AUSLEIHEN ===')
 for b in aus.find({'Status': 'planned'}).limit(3):
    print(f\"Start: {b.get('Start')} | Typ: {type(b.get('Start')).__name__}\")
    print(f\"Periode: {b.get('Period')} | User: {b.get('User')}\")
    print(f\"Jetzt > Start? {datetime.datetime.now() > b.get('Start', datetime.datetime.max)}\")
    print()
 "
 ```
 ---
 ## 💡 EMPFOHLENE EINSTELLUNG FÜR SCHULEN
 In `config.json` verwende diese Werte:
 ```json
 {
  "scheduler": {
    "enabled": true,
    "interval_minutes": 1,
    "backup_interval_hours": 24
  }
 }
 ```
 Dies checkt **jede Minute** ob Termine aktiviert werden sollen - perfekt für Schulstunden.
 ---
 ## Weitere Hilfe?
 Falls das nicht funktioniert:
 1. Schreib mir die **exakte Uhrzeit** wann du die Ausleihe erstellt hast
 2. Und wann sie hätte aktiviert werden sollen
 3. Zeige mir ein Beispiel aus der DB mit `docker exec inventarsystem-mongodb mongosh...`

 ## Tenant Management Operationen (manage-tenant.sh)
 Um einzelne Tenants im Multi-Tenant-Umfeld im laufenden Betrieb und ohne globale Downtime zu verwalten, kann das neue CLI-Skript `manage-tenant.sh` verwendet werden.
 ### 1. Neuen Tenant hinzufügen
 Initialisiert die MongoDB-Datenbankstruktur isoliert für einen neuen Tenant und legt initiale Admin-Zugangsdaten an.
 ```bash
 ./manage-tenant.sh add <tenant_id>
 ```
 ### 2. Bestimmten Tenant neu starten (Soft-Restart)
 Erzwingt sofortigen Logout und einen Cache/Session-Reset für die Nutzer *eines spezifischen* Tenants, ohne andere laufende Instanzen zu beeinträchtigen. Ideal bei Konfigurationsänderungen oder feststeckenden Sessions.
 ```bash
 ./manage-tenant.sh restart-tenant <tenant_id>
 ```
 ### 3. Tenant sicher entfernen
 Löscht die dedizierte MongoDB-Datenbank des gewählten Tenants vollständig (erfordert Bestätigung).
 ```bash
 ./manage-tenant.sh remove <tenant_id>
 ```
 ### 4. Globale Operationen
 ```bash
 # Zeigt alle aktiven isolierten Tenant-Datenbanken an
 ./manage-tenant.sh list
 # Führt einen Zero-Downtime Rolling-Restart aller Application-Container durch
 ./manage-tenant.sh restart-all
 ```

 ## Aktuelle UI- & Funktionsoptimierungen (Release April 2026)
 Neben der Docker-Auslagerung wurden spezifische Caching-, Parsing-, und DOM-Tricks integriert, die das Setup weiter entschlacken:
 * **DOM Array Slicing für Bilder:** Bei großen Beständen (hunderte Artikel) rendert der Client im Listen/Kachel-Modus künftig nur noch das primäre Bild (`slice(0, 1)`), was den DOM-Memory-Footprint drastisch reduziert und das Einfrieren von Browsern verhindert.
 * **Auto-Ingestion von Excel-Filtern:** Der Excel-Importer prüft nun dynamisch neue `categories/filter`, die noch nicht in der Datenbank existieren, und speichert sie direkt in die MongoDB `filter_presets`-Kollektion (Zero-Config für Administratoren).
 * **Responsive UI Synchronisierung:** Die Standardansicht (`main.html`) der Smartphones wurde CSS-technisch exakt an das skalierungsfähigere Profil der Admin-Mobile-Ansicht (`main_admin.html`) angeglichen.

 ## Schul-Konfiguration pro Tenant
 Die Datei `config.json` unterstützt jetzt einen `tenants`-Block. Damit kann jede Schule eigene Modul-Schalter bekommen, ohne dass das ganze System global umgestellt werden muss.
 ```json
 {
    "tenants": {
        "schule1": {
            "modules": {
                "library": { "enabled": true },
                "student_cards": { "enabled": false }

                "library": { "enabled": false }
            }
        }
    }
 }
 ```
 Wenn ein Request über Subdomain oder `X-Tenant-ID` aufgelöst wird, liest die App diese Werte automatisch aus und blendet die Bibliothek bzw. andere Module nur für diesen Tenant ein oder aus.

 # Multi-Tenant Python Management API
 This document explains how the multi-tenant architecture isolates data within Python, what the return values are, and how developers can build internal administrative scripts using native Python instead of the Docker CLI. 
 ## 1. Architectural Concept
 In the system, each "tenant" is essentially a dedicated MongoDB database identified by a dynamically generated string based on a subdomain or header (`inventar_<tenant_id>`). 
 App containers share a connection pool using `pymongo.MongoClient`, and requests are routed to specific databases dynamically based on the current Flask `g.tenant_context`.
 All MongoDB administrative tasks (creating tenants, restarting apps, fetching lists) are done via standard MongoDB Python drivers because the core multi-tenancy happens at the **database level**.
 ## 2. Managing Tenants via Python
 If you want to perform multi-tenant administrative operations without traversing through `manage-tenant.sh`, you can execute native Python scripts connecting to the system's `MongoClient`.
 ### Basic Connection Boilerplate
 Whenever automating an administrative task in Python, you simply need to connect to MongoDB using the properties defined in `settings.py`.
 ```python
 import sys
 import os
 # Append Web folder so we can access configuration
 sys.path.insert(0, '/app/Web')
 import settings
 from pymongo import MongoClient
 # Establish connection pooling
 client = MongoClient(settings.MONGODB_HOST, int(settings.MONGODB_PORT))
 ```
 ### A. Adding a New Tenant (Database Initialization)
 A new tenant database isn’t provisioned until the first actual data insert happens. We trigger this manually by creating an `admin` user for them.
 **Operation:**
 ```python
 def create_tenant(tenant_id, admin_password="hashed_password_here"):
    db_name = f"{settings.MONGODB_DB}_{tenant_id}"
    db = client[db_name]
    # MongoDB creates the DB automatically on first insert
    result = db.users.insert_one({
        'username': 'admin',
        'password': admin_password,
        'role': 'admin'
    })
    return result.inserted_id # Returns the BSON ObjectId of the new user
 ```
 ### B. List Active Tenants
 To find out how many isolated tenants have active databases, you query the raw `MongoClient` for all databases and search for your configured MongoDB prefix (default: `inventar_`).
 **Operation:**
 ```python
 def list_tenants():
    prefix = f"{settings.MONGODB_DB}_"
    # Returns a Python list of string database names
    all_dbs = client.list_database_names() 
    # Filter and strip the prefix to return just the tenant_ids
    active_tenants = [d.replace(prefix, "") for d in all_dbs if d.startswith(prefix)]
    return active_tenants # e.g., ['schule1', 'schule2', 'test']
 ```
 ### C. Soft-Restarting a Tenant (Invalidating Sessions)
 "Restarting" a single tenant means signing out all of their users and forcing an application refresh. Because Session data is coupled to the tenant database, dropping their `sessions` collection achieves an instant sign-out.
 **Operation:**
 ```python
 def restart_tenant(tenant_id):
    db_name = f"{settings.MONGODB_DB}_{tenant_id}"
    db = client[db_name]
    # Drops the collection. All active user cookies immediately become invalid.
    result = db.sessions.drop() 
    return result # Returns None. Raises PyMongoError if connection fails.
 ```
 ### D. Removing a Tenant Completely (Wipe Data)
 If a tenant is removed from the service or their lease expires, you can permanently obliterate their data container footprint.
 **Operation:**
 ```python
 def remove_tenant(tenant_id):
    db_name = f"{settings.MONGODB_DB}_{tenant_id}"
    # Erases the isolated database. Can't be undone.
    client.drop_database(db_name) 
    return True # Returns True. Raises PyMongoError if connection fails.
 ```
 ## 3. Resolving Context Inside Flask (app.py)
 If you are building custom application endpoints inside `Web/app.py`, you shouldn't use the direct MongoDB `client` manually. Instead, you rely on the built-in Flask context manager (`Web/tenant.py`) to give you the correct isolated scope.
 ### The `get_tenant_db()` function
 Every route must use `get_tenant_db(client)` to ensure users can only ever access their own school/domain's database.
 ```python
 from pymongo import MongoClient
 import settings
 from tenant import get_tenant_db
 # Example Route
@app.route('/api/items')
 def get_items():
    # 1. Establish/reuse pooling connection
    client = MongoClient(settings.MONGODB_HOST, settings.MONGODB_PORT)
    # 2. Get the dynamically routed DB for THIS user 
    # (Based on Nginx Subdomain or X-Tenant-Id header)
    db = get_tenant_db(client) 
    # 3. Runs query solely on `inventar_schule1.items`
    items = list(db.items.find())
    return items # List of BSON Dictionaries
 ```
 **What it returns internally:**
 The `get_tenant_db` function queries `g.tenant_context` inside Flask, calculates the database name from the subdomain, and returns a live `pymongo.database.Database` object. 
 This ensures that scaling is extremely cheap on resources because 1 Application Container connects to 100 separate Tenant Databases using just 1 shared `MongoClient` pool.

 - **PDF/A-Kompatibilität** (30+ Jahre Lesbarkeit)
 - **Deutsche Behörden** (Bundesarchiv Standard)
 - **Rechtssicherheit** (gerichtlich verwertbar)
 ## Technische Architektur
 ### Klassenliste
 #### `DIN5008AuditPDF`
 Hauptklasse für PDF-Generierung
 **Constructor:**
 ```python
 DIN5008AuditPDF(school_info=None, export_type='official')
 ```
 **Parameter:**
 - `school_info` (dict): Schulinformationen (optional)
 - `export_type` (str): 'quick' oder 'official'
 **Methoden:**
 - `generate_quick_check(verify_result, event_counts, audit_rows)` → PDF bytes
 - `generate_official_report(verify_result, event_counts, audit_rows)` → PDF bytes
 **Interne Methoden:**
 - `_add_header()` - Briefkopf
 - `_add_title()` - Titel
 - `_add_audit_summary()` - Zusammenfassung
 - `_add_events_table()` - Ereignistabelle
 - `_add_mismatches()` - Fehler-Sektion
 - `_add_signature_block()` - Unterschriftsfeld

 generate_audit_pdf(
    verify_result,      # dict - Verifikationsergebnis
    event_counts,       # list - Ereignistypen
    audit_rows,         # list - Audit-Einträge
    export_type='official',  # str
    school_info=None    # dict
 ) → bytes
 ```
 **Rückgabewert**: PDF als Bytes (bereit zum Download)
 ### Code-Integration in app.py
 #### Helper-Funktion

 # Multi-Tenant Migration Checklist
 ## Automated Steps Completed
 - [x] Backup created
 - [x] Tenant modules verified
 - [x] Docker files prepared
 - [x] app.py imports prepared
 - [x] requirements.txt updated
 ## Manual Steps Required
 ### 1. Update app.py Configuration (5 min)
 Add after `app = Flask(...)`:
 ```python
 # Multi-Tenant Configuration
 if os.getenv('INVENTAR_SESSION_BACKEND') == 'redis':
    try:
        app.session_interface = create_redis_session_interface(app)
        app.logger.info("Redis session backend enabled")
    except Exception as e:
        app.logger.warning(f"Redis session backend failed: {e}")
 ```
 ### 2. Add Health Check Endpoint (5 min)
 Add this route:
 ```python
@app.route('/health')
 def health_check():
    try:
        mongo = MongoClient(cfg.MONGODB_HOST, cfg.MONGODB_PORT)
        mongo.admin.command('ping')
        return {'status': 'healthy'}, 200
    except Exception as e:
        return {'status': 'unhealthy'}, 503
 ```
 ### 3. Update Database Access (10-30 min)
 Change existing routes to use:
 ```python
@require_tenant
 def your_route():
    db = get_tenant_db(MongoClient(...))
    # Use db as usual
 ```
 ### 4. Setup DNS (5 min)
 Create wildcard DNS record:
 ```
 *.example.com IN A your-server-ip
 ```
 ### 5. Create SSL Certificate (10 min)
 ```bash
 # Let's Encrypt (recommended)
 sudo certbot certonly --manual --preferred-challenges dns \
    -d "*.example.com" -d "example.com"
 # Copy to certs folder
 cp /etc/letsencrypt/live/example.com/fullchain.pem certs/inventarsystem.crt
 cp /etc/letsencrypt/live/example.com/privkey.pem certs/inventarsystem.key
 ```
 ### 6. Deploy Multi-Tenant
 ```bash
 # Install dependencies
 pip install -r requirements.txt
 # Start Multi-Tenant deployment
 docker-compose -f docker-compose-multitenant.yml up -d
 # Test
 curl https://test.example.com/health
 ```
 ### 7. Verify (5 min)
 ```bash
 # Check logs
 docker-compose logs app
 # Verify each tenant
 curl https://schule1.example.com/debug/tenant
 curl https://schule2.example.com/debug/tenant
 # Cache stats
 curl https://schule1.example.com/debug/cache-stats
 ```
 ## Rollback Plan
 If something goes wrong:
 1. Stop Multi-Tenant deployment
   ```bash
   docker-compose -f docker-compose-multitenant.yml down
   ```
 2. Restore from backup
   ```bash
   cp .migration-backup-*/app.py Web/app.py
   cp .migration-backup-*/settings.py Web/settings.py
   ```
 3. Restart original deployment
   ```bash
   docker-compose up -d
   ```
 ## Performance Expectations
 - Memory per instance: 100-150MB (was 200MB)
 - Response time: -30% (Redis caching)
 - Max concurrent users: 3x increase
 - Database load: -70% (query caching)
 ## Support
 - Check logs: `docker-compose -f docker-compose-multitenant.yml logs -f app`
 - Debug tenant: `curl https://your-tenant.com/debug/tenant`
 - See MULTITENANT_DEPLOYMENT.md for detailed guide

 Options:
  --source <path>         Backup source path.
                          Supported:
                          - old folder with CSV files
                          - old Inventarsystem-*.tar.gz backup
                          - new mongodb-*.archive.gz backup
                          - folder containing mongodb-*.archive.gz
  --date <value>          Resolve source from known backup locations.
                          - YYYY-MM-DD: checks backups/YYYY-MM-DD and /var/backups/Inventarsystem-YYYY-MM-DD(.tar.gz)
                          - latest: newest from local/system backup roots
  --drop-database         Drop target DB before import (recommended for full restore)
  --restart-services      Restart stack after restore
  --list                  List detected backup candidates
  --help                  Show this help
 Notes:
  - Always restores into current DB name: $DB_NAME
  - Supports both legacy CSV and new archive backups
  - Normalizes collection names to current structure (users, items, ausleihungen, filter_presets, settings)
