## Multi-Tenant Plugin
|
|
|
|
Verwendet `@payloadcms/plugin-multi-tenant` für Mandantenfähigkeit.
|
|
|
|
**Aktuelle Tenants:**
|
|
| ID | Name | Slug |
|
|
|----|------|------|
|
|
| 1 | porwoll.de | porwoll |
|
|
| 4 | Complex Care Solutions GmbH | c2s |
|
|
| 5 | Gunshin | gunshin |
|
|
|
|
**User-Tenant-Zuweisung:** Tabelle `users_tenants`
|
|
|
|
## Wichtige Befehle
|
|
|
|
```bash
|
|
# Entwicklung
|
|
pnpm dev
|
|
|
|
# Production Build
|
|
pnpm build
|
|
|
|
# Migrationen
|
|
pnpm payload migrate:create
|
|
pnpm payload migrate
|
|
|
|
# ImportMap nach Plugin-Änderungen
|
|
pnpm payload generate:importmap
|
|
|
|
# PM2
|
|
pm2 status
|
|
pm2 logs payload
|
|
pm2 restart payload
|
|
|
|
# Datenbank prüfen
|
|
PGPASSWORD=Finden55 psql -h 10.10.181.101 -U payload -d payload_db
|
|
```
|
|
|
|
## Workflow nach Code-Änderungen
|
|
|
|
1. Code ändern
|
|
2. `pnpm build`
|
|
3. `pm2 restart payload`
|
|
4. Testen unter https://pl.c2sgmbh.de/admin
|
|
|
|
## Bekannte Besonderheiten
|
|
|
|
- **ES Modules:** package.json hat `"type": "module"`, daher PM2 Config als `.cjs`
|
|
- **Plugin ImportMap:** Nach Plugin-Änderungen `pnpm payload generate:importmap` ausführen
|
|
- **User-Tenant-Zuweisung:** Neue User müssen manuell Tenants zugewiesen bekommen
|
|
|
|
## Build-Konfiguration
|
|
|
|
Der Build ist für speichereffizientes Kompilieren optimiert:
|
|
|
|
- `package.json`: `--max-old-space-size=2048` (2GB Heap-Limit)
|
|
- `next.config.mjs`: `experimental.cpus: 1`, `workerThreads: false`
|
|
|
|
**WICHTIG:** Der Server hat nur 4GB RAM ohne Swap. Bei laufendem VS Code Server muss der Build mit reduziertem Memory ausgeführt werden:
|
|
|
|
```bash
|
|
pm2 stop payload # Speicher freigeben
|
|
NODE_OPTIONS="--no-deprecation --max-old-space-size=1024" ./node_modules/.bin/next build
|
|
pm2 start payload
|
|
```
|
|
|
|
Ohne PM2-Stop und mit VS Code wird der Build vom OOM Killer beendet (Exit code 137).
|
|
|
|
## Mehrsprachigkeit (i18n)
|
|
|
|
Das System unterstützt Deutsch (default) und Englisch:
|
|
|
|
- **Admin UI:** `@payloadcms/translations` für DE/EN
|
|
- **Content:** Localization mit Fallback auf Deutsch
|
|
- **Datenbank:** 36 `_locales` Tabellen für lokalisierte Felder
|
|
- **API:** `?locale=de` oder `?locale=en` Parameter
|
|
- **Frontend:** Routing über `/[locale]/...`
|
|
|
|
```bash
|
|
# Locales in der Datenbank prüfen
|
|
PGPASSWORD=Finden55 psql -h 10.10.181.101 -U payload -d payload_db -c "\dt *_locales"
|
|
```
|
|
|
|
## URLs
|
|
|
|
- **Admin Panel:** https://pl.c2sgmbh.de/admin
|
|
- **API:** https://pl.c2sgmbh.de/api
|
|
- **E-Mail API:** https://pl.c2sgmbh.de/api/send-email (POST, Auth erforderlich)
|
|
|
|
## E-Mail-System
|
|
|
|
Multi-Tenant E-Mail-System mit tenant-spezifischer SMTP-Konfiguration:
|
|
|
|
**Architektur:**
|
|
- Globaler SMTP als Fallback (via .env)
|
|
- Tenant-spezifische SMTP in Tenants Collection
|
|
- Transporter-Caching mit automatischer Invalidierung
|
|
- EmailLogs Collection für Audit-Trail
|
|
|
|
**Tenant E-Mail-Konfiguration:**
|
|
```
|
|
Tenants → email → fromAddress, fromName, replyTo
|
|
→ email → useCustomSmtp (Checkbox)
|
|
→ email → smtp → host, port, secure, user, pass
|
|
```
|
|
|
|
**API-Endpoint `/api/send-email`:**
|
|
```bash
|
|
curl -X POST https://pl.c2sgmbh.de/api/send-email \
|
|
-H "Content-Type: application/json" \
|
|
-H "Cookie: payload-token=..." \
|
|
-d '{
|
|
"to": "empfaenger@example.com",
|
|
"subject": "Betreff",
|
|
"html": "<p>Inhalt</p>",
|
|
"tenantId": 1
|
|
}'
|
|
```
|
|
|
|
**Sicherheit:**
|
|
- Authentifizierung erforderlich
|
|
- Tenant-Zugriffskontrolle (User muss Tenant-Mitglied sein)
|
|
- Rate-Limiting: 10 E-Mails/Minute pro User
|
|
- SMTP-Passwort nie in API-Responses
|
|
|
|
## Redis Caching
|
|
|
|
Redis wird für API-Response-Caching und E-Mail-Transporter-Caching verwendet:
|
|
|
|
```typescript
|
|
import { redis } from '@/lib/redis'
|
|
|
|
// Cache setzen (TTL in Sekunden)
|
|
await redis.set('key', JSON.stringify(data), 'EX', 60)
|
|
|
|
// Cache lesen
|
|
const cached = await redis.get('key')
|
|
|
|
// Pattern-basierte Invalidierung
|
|
await redis.keys('posts:*').then(keys => keys.length && redis.del(...keys))
|
|
```
|
|
|
|
## Datenbank-Direktzugriff
|
|
|
|
```bash
|
|
PGPASSWORD=Finden55 psql -h 10.10.181.101 -U payload -d payload_db
|
|
|
|
