---

## ✅ FILE YANG DIBUAT / DIUBAH

### 📝 **File Baru (NEW)**

#### 1. `app/Models/Classification.php`
```php
class Classification extends Model
{
    protected $fillable = [
        'image_path',
        'filename',
        'predicted_class',
        'confidence',
        'all_predictions',
        'disease_name',
        'severity',
        'notes',
    ];

    protected $casts = [
        'all_predictions' => 'array',
        'confidence' => 'float',
    ];
}
```
- Model untuk table `classifications`
- Supports JSON casting untuk `all_predictions`
- Timestamps otomatis (created_at, updated_at)

#### 2. `database/migrations/2026_03_08_182722_create_classifications_table.php`
```php
Schema::create('classifications', function (Blueprint $table) {
    $table->id();
    $table->string('image_path')->nullable();
    $table->string('filename');
    $table->string('predicted_class');
    $table->float('confidence');
    $table->json('all_predictions');
    $table->string('disease_name')->nullable();
    $table->string('severity')->nullable();
    $table->text('notes')->nullable();
    $table->timestamps();
});
```
- 10 columns untuk store data lengkap
- JSON column untuk all_predictions
- Nullable fields untuk optional data
- **Status:** ✅ Executed successfully (347.26ms)

#### 3. `app/Http/Controllers/ClassificationHistoryController.php` ⭐ NEW
```php
class ClassificationHistoryController extends Controller
{
    public function index()              // GET /api/classifications
    public function show($id)            // GET /api/classifications/{id}
    public function destroy($id)         // DELETE /api/classifications/{id}
    public function stats()              // GET /api/classifications/stats/summary
}
```
- **index()**: List semua dengan pagination (15/page)
- **show()**: Detail single record dengan all_predictions JSON
- **destroy()**: Delete record + cleanup image file
- **stats()**: Aggregate stats (total, average confidence, breakdown by disease)

---

### ✏️ **File yang Diubah (UPDATED)**

#### 1. `app/Http/Controllers/ClassificationController.php`
**Perubahan:** Tambah `Classification::create()` untuk save data

Sebelum (hanya return response):
```php
return response()->json(['success' => true, 'data' => $result]);
```

Sesudah (save to database):
```php
// Get disease info
$diseaseInfo = getDiseaseInfo($result['predicted_class']);

// Save to database
Classification::create([
    'image_path' => $path,
    'filename' => $file->getClientOriginalName(),
    'predicted_class' => $result['predicted_class'],
    'confidence' => $result['confidence'],
    'all_predictions' => $result['all_predictions'],
    'disease_name' => $diseaseInfo['name'] ?? null,
    'severity' => $diseaseInfo['severity'] ?? null,
    'notes' => null,
]);

return response()->json(['success' => true, 'data' => $result]);
```

#### 2. `routes/api.php`
**Perubahan:** Tambah classification history routes

```php
// Classification endpoints
Route::post('/classify', [ClassificationController::class, 'classify']);
Route::post('/classify-and-save', [ClassificationController::class, 'classifyAndSave']);
Route::get('/test', [ClassificationController::class, 'testConnection']);

// History endpoints (NEW)
Route::get('/', [ClassificationHistoryController::class, 'index']);
Route::get('/{id}', [ClassificationHistoryController::class, 'show']);
Route::delete('/{id}', [ClassificationHistoryController::class, 'destroy']);
Route::get('/stats/summary', [ClassificationHistoryController::class, 'stats']);
```

Total: **7 endpoints** untuk classification & history

## 🧪 Testing Endpoints

### 1. Test Save Classification
```bash
curl -X POST http://127.0.0.1:8000/api/classification/classify-and-save \
  -F "image=@rice_leaf.jpg"
```
**Expected Response:**
```json
{
  "success": true,
  "data": {
    "predicted_class": "Bacterialblight",
    "confidence": "95.23%",
    "disease_info": "Bercak Bakteri..."
  }
}
```
✓ Record akan tersimpan di table `classifications`

### 2. Get All Classifications
```bash
curl http://127.0.0.1:8000/api/classifications?page=1
```
**Expected:** List dengan pagination

### 3. Get Statistics
```bash
curl http://127.0.0.1:8000/api/classifications/stats/summary
```
**Expected:** Total count, average confidence, breakdown by disease

### 4. Delete Classification
```bash
curl -X DELETE http://127.0.0.1:8000/api/classifications/1
```
**Expected:** Record + image deleted

---

## 📈 Statistics Query

```php
// Get statistics
$total = Classification::count();
$avgConfidence = Classification::avg('confidence');
$byDisease = Classification::select('disease_name')
    ->groupBy('disease_name')
    ->selectRaw('count(*) as count')
    ->get();
```

---

---

## 🚀 Next Steps

1. **Start Laravel Server**: `php artisan serve --port=8000`
2. **Start Python API**: `python api_server.py` (port 5000)
3. **Run Flutter**: `flutter run` (emulator/device)
4. **Test Full Integration**:
   - Upload gambar dari mobile
   - Verify record di database
   - Test history endpoints
   - Test statistics
5. **Create Dashboard** (optional):
