# Analyse: Laravel Models vs Migrations vs Datenbank

## Übersicht

Diese Analyse vergleicht die Laravel Eloquent Models mit den entsprechenden Migration-Dateien und der tatsächlichen Datenbankstruktur.

---

## **1. Company Model & Migration**

### ✅ **PERFEKT SYNCHRON**

#### Migration
**Datei**: [database/migrations/2025_10_20_181750_create_companies_table.php](database/migrations/2025_10_20_181750_create_companies_table.php)

```php
Schema::create('companies', function (Blueprint $table) {
    $table->id();
    $table->string('name')->unique();
    $table->string('legal_name')->nullable();
    $table->string('ticker')->nullable();
    $table->string('sector')->nullable();
    $table->string('country', 2)->default('DE');
    $table->string('headquarters')->nullable();
    $table->string('kyc_risk_level')->default('medium');
    $table->text('summary')->nullable();
    $table->timestamps();
});
```

**Felder**:
- `id` (auto-increment)
- `name` (string, unique)
- `legal_name` (string, nullable)
- `ticker` (string, nullable)
- `sector` (string, nullable)
- `country` (string(2), default: 'DE')
- `headquarters` (string, nullable)
- `kyc_risk_level` (string, default: 'medium')

#### Model
**Datei**: [app/Models/Company.php](app/Models/Company.php)

```php
protected $fillable = [
    'name',

    'ticker',
    'sector',
    'country',
    'headquarters',
    'kyc_risk_level',
    'summary',

    'signals' => 'array',
];

// Relationship
public function company(): BelongsTo

        default => __('Freigegeben'),
    };
}
```

### ⚠️ **FEHLENDE FELDER IM MODEL**

Das Transaction Model hat **NUR 14 Core-Felder** im `$fillable` Array, aber die Migration definiert **49 Felder** (exkl. timestamps).

#### Fehlende Enrichment-Felder (34 Spalten):

**Registry-Felder:**
- `registry_company_number`
- `registry_source`
- `registry_match_score`
- `registry_data`
- `registry_last_refreshed_at`

**Genesis-Felder:**
- `genesis_context`
- `genesis_last_refreshed_at`

**GovData-Felder:**
- `govdata_data`
- `govdata_last_refreshed_at`

**Handelsregister-Felder:**
- `handelsregister_data`
- `handelsregister_last_refreshed_at`
- `handelsregister_status`
- `handelsregister_entity_id`

### ⚠️ **FEHLENDE CASTS**

Das Model sollte Casts für alle zeitbasierten und JSON-Felder haben:

**Fehlende DateTime-Casts:**
- `registry_last_refreshed_at`
- `genesis_last_refreshed_at`
- `govdata_last_refreshed_at`
- `bundesanzeiger_last_refreshed_at`
- `insolvency_last_refreshed_at`

## **3. Vergleich: Datenbank vs Migration**

### public.companies

**Status**: ✅ **100% Übereinstimmung**

| Feature | Migration | Datenbank | Status |
|---------|-----------|-----------|--------|
| Spalten | 11 | 11 | ✅ |
| Unique Constraint | `name` | `name` | ✅ |
| Defaults | `country='DE'`, `kyc_risk_level='medium'` | Identisch | ✅ |

### public.transactions

**Status**: ✅ **Migration deckt alle DB-Felder ab**

#### Constraints & Indizes
| Constraint | Migration | Datenbank | Status |
|------------|-----------|-----------|--------|
| Foreign Key | `company_id → companies.id` | Vorhanden | ✅ |
| Cascade Delete | `cascadeOnDelete()` | Implementiert | ✅ |
| Unique | `reference` | Vorhanden | ✅ |
| Index | `status` | Vorhanden | ✅ |

#### Datentypen-Vergleich

| Feld | Migration | Datenbank | Status |
|------|-----------|-----------|--------|
| id | `id()` | bigint | ✅ |
| company_id | `foreignId()` | bigint | ✅ |
| amount | `decimal(16,2)` | numeric | ✅ |
| currency | `string(3)` | varchar | ✅ |
| counterparty_country | `string(2)` | varchar | ✅ |
| risk_score | `unsignedTinyInteger` | smallint | ⚠️* |
| status | `string(32)` | varchar | ✅ |
| requires_review | `boolean` | boolean | ✅ |
| signals | `json` | json | ✅ |
| *_data | `jsonb` | jsonb | ✅ |
| gleif_data | `json` | json | ✅ |
| executed_at | `dateTime` | timestamp | ✅ |
| *_last_refreshed_at | `dateTime` | timestamp | ✅ |

*`unsignedTinyInteger` (0-255) vs `smallint` (-32768 bis 32767) sind funktional kompatibel

   - Alle Datenbank-Felder korrekt definiert
   - Foreign Key Constraints implementiert
   - Indizes sinnvoll gesetzt

2. **Core-Model-Felder stimmen überein**
   - Basis-Transaktionsfelder vollständig
   - Relationships sauber definiert

3. **Datenbank-Konsistenz**
   - Migrations wurden korrekt ausgeführt
   - Constraints sind aktiv

---

## ⚠️ **Probleme & Empfehlungen**

### Problem 1: Transaction Model ist unvollständig

**Problem**:
- Das Model definiert nur 14 von 49 Feldern im `$fillable` Array
- Alle 34 Enrichment-Felder fehlen

**Auswirkungen**:
- ❌ Enrichment-Felder können nicht via Mass Assignment gesetzt werden
- ❌ Keine automatischen Type Casts für externe Datenfelder
- ❌ Potenzielle Fehler beim Zugriff auf nicht-gecastete JSON-Daten
- ❌ DateTime-Felder werden als Strings zurückgegeben

**Lösungsvorschläge**:

**Option 1**: Alle Felder zu `$fillable` hinzufügen
```php
protected $fillable = [
    // Core fields
    'company_id', 'reference', 'amount', 'currency',
    'counterparty', 'counterparty_country', 'channel',
    'executed_at', 'risk_score', 'status',
    'requires_review', 'flagged_by', 'flagged_reason', 'signals',

    // Registry
    'registry_company_number', 'registry_source', 'registry_match_score',
    'registry_data', 'registry_last_refreshed_at',

    // Genesis
    'genesis_context', 'genesis_last_refreshed_at',

    // ... alle weiteren Felder
];
```

**Option 2**: `$guarded` verwenden (empfohlen für interne Anwendungen)
```php
protected $guarded = ['id'];
```

**Option 3**: Separate Accessor/Mutator für Enrichment-Felder
```php
public function registryData(): Attribute
{
    return Attribute::make(
        get: fn ($value) => json_decode($value, true),
        set: fn ($value) => json_encode($value),
    );
}
```

### Problem 2: Fehlende Casts für Enrichment-Felder

**Problem**:
- Keine Casts für `*_last_refreshed_at` Felder
- Keine Casts für `*_data` JSON-Felder

**Auswirkungen**:
- DateTime-Felder werden als Strings zurückgegeben (kein Carbon-Objekt)
- JSON-Felder müssen manuell dekodiert werden

**Lösung**:
```php
protected $casts = [
    // Existing
    'executed_at' => 'datetime',
    'requires_review' => 'boolean',
    'signals' => 'array',

    // DateTime casts for all refresh timestamps
    'registry_last_refreshed_at' => 'datetime',
    'genesis_last_refreshed_at' => 'datetime',
    'govdata_last_refreshed_at' => 'datetime',
    'bundesanzeiger_last_refreshed_at' => 'datetime',
    'insolvency_last_refreshed_at' => 'datetime',
    'rss_last_refreshed_at' => 'datetime',
    'sanctions_last_refreshed_at' => 'datetime',
    'pep_last_refreshed_at' => 'datetime',
    'gleif_last_refreshed_at' => 'datetime',
    'eu_sanctions_last_refreshed_at' => 'datetime',
    'handelsregister_last_refreshed_at' => 'datetime',

    // JSON/Array casts for all data fields
    'registry_data' => 'array',
    'genesis_context' => 'array',
    'govdata_data' => 'array',
    'bundesanzeiger_data' => 'array',
    'insolvency_data' => 'array',
    'rss_alerts' => 'array',
    'sanctions_data' => 'array',
    'pep_data' => 'array',
    'gleif_data' => 'array',
    'eu_sanctions_data' => 'array',
    'handelsregister_data' => 'array',
];
```

### Problem 3: Datenbank-Schema-Anomalie

**Problem**:
- Die `public.transactions` Tabelle zeigt 9x duplizierte `id` Spalten im describe_table Output

**Mögliche Ursachen**:
- Korruptes Schema-Metadaten
- Mehrfache Migration-Ausführungen ohne Rollback
- PostgreSQL-Katalog-Problem

**Lösung**:
1. Schema inspizieren: `\d+ transactions` in psql
2. Bei Bedarf Migration neu ausführen
3. Oder manuelles ALTER TABLE zur Bereinigung

---

## Nächste Schritte

### Empfohlene Reihenfolge:

1. ✅ **Transaction Model aktualisieren**
   - Alle fehlenden Felder zu `$fillable` hinzufügen
   - Alle fehlenden Casts definieren

2. ✅ **Tests schreiben**
   - Unit-Tests für Model-Casts
   - Feature-Tests für Enrichment-Datenfluss

3. ⚠️ **Datenbank-Anomalie untersuchen**
   - PostgreSQL-Schema inspizieren
   - Ggf. Migration neu ausführen

4. 📝 **Dokumentation erweitern**
   - Enrichment-Pipeline dokumentieren
   - API für externe Datenquellen dokumentieren
