## 📊 Database Queries (php artisan tinker)

```bash
php artisan tinker

# Count records
>>> DB::table('classifications')->count()

# Get latest classification
>>> DB::table('classifications')->latest()->first()

# Get specific classification
>>> App\Models\Classification::find(1)

# List all with pagination
>>> App\Models\Classification::paginate(15)

# Get by disease
>>> App\Models\Classification::where('disease_name', 'Bercak Bakteri')->get()

# Get high confidence
>>> App\Models\Classification::where('confidence', '>=', 0.9)->get()

# Get statistics
>>> DB::table('classifications')->selectRaw('disease_name, count(*) as count')->groupBy('disease_name')->get()

# Clear all (WARNING: DELETES ALL DATA)
>>> DB::table('classifications')->truncate()

## 🔧 Common Issues & Fixes

| Issue | Fix |
|-------|-----|
| Port 5000/8000 in use | `netstat -an \| findstr :5000` to find process |
| Database not connected | Check `.env` credentials: `php artisan tinker` → `DB::connection()->getPdo()` |
| Flutter API timeout | Check API URL for emulator (10.0.2.2) vs device (192.168.x.x) |
| Image not saving | Check `storage/app/public` is writable: `chmod 775 storage/` |
| Migration failed | Reset: `php artisan migrate:rollback` then `php artisan migrate` |

---

## ✅ Verification Commands

```bash
# Check Laravel status
php artisan migrate:status

# Check model fillable properties
php artisan tinker
>>> (new App\Models\Classification())->getFillable()

# Check table structure
php artisan tinker
>>> DB::table('classifications')->getColumns()

# Check routes
php artisan route:list | grep classifications

# Check for errors
php artisan optimize:clear
```

## 📱 Mobile API URL Configuration

### For Android Emulator
```dart
// classification_service.dart
static const String baseUrl = 'http://10.0.2.2:8000/api/classification';
/* 10.0.2.2 = Your computer's localhost from emulator */
```

### For Physical Device
```dart
// Findyour computer IP first:
// ipconfig → Look for IPv4 Address (e.g., 192.168.1.100)

static const String baseUrl = 'http://192.168.1.100:8000/api/classification';
// Replace IP with your actual computer IP
```

## 🚄 Performance Metrics

| Operation | Time |
|-----------|------|
| Classify image | 2-3 sec |
| Save to DB | < 100ms |
| Get list | ~150ms |

## 🎯 Testing Checklist

```
□ Server 1: Laravel runs on :8000
□ Server 2: Python API runs on :5000
□ Server 3: Flutter app launches
□ Test connection: GET /test succeeds
□ Test classify: POST /classify returns result
□ Test save: POST /classify-and-save saves to DB
□ Test history: GET /classifications shows data
□ Test stats: GET /stats returns numbers
□ Test mobile: App classifies and shows result
□ Test error handling: Server down shows error
```

## 💾 Database Backup/Restore

```bash
# Backup current database
mysqldump -u root -p classification_db > backup_$(date +%Y%m%d_%H%M%S).sql

# Restore from backup
mysql -u root -p classification_db < backup_20260309_100000.sql

# Clear all classifications
php artisan tinker
>>> DB::table('classifications')->truncate()
```

## 🎓 Important Concepts

### Fillable Array
Prevents accidental mass assignment security vulnerability
```php
$fillable = ['field1', 'field2']; // Only these can be mass assigned
```

### Type Casting
Automatic conversion of data types
```php
$casts = [
    'all_predictions' => 'array',  // JSON → PHP array
    'confidence' => 'float',        // String → float
];
```

### Timestamps
Laravel automatically manages created_at & updated_at
```php
// No need to set manually
Classification::create([...]);  // Timestamps auto-set
```

### Pagination
Automatically splits large datasets
```php
Classification::paginate(15);  // Returns 15 per page
```

### JSON Column
Store complex data as JSON in database
```php
all_predictions: {
    "Bacterialblight": 0.95,
    "Brownspot": 0.04,
    "Leafsmut": 0.01
}
```

## 🔐 Security Notes

- ✅ CSRF protection enabled (Laravel default)
- ✅ Mass assignment protected ($fillable)
- ✅ Database credentials in .env
- ⚠️ TODO: Add API authentication
- ⚠️ TODO: Add authorization checks
- ⚠️ TODO: Add rate limiting

---

## 📊 System Capacity

| Metric | Limit |
|--------|-------|
| Concurrent requests | 100+ (depends on server) |
| Classifications stored | Unlimited (10GB DB ~1M records) |
| Image file size | 10MB max (configurable) |
| Response time | < 5 seconds (target) |
| Pagination | 15 per page |

## 🎯 Success = All This Works

1. ✅ Can start all 3 servers
2. ✅ Can upload image from mobile
3. ✅ Get classification result
4. ✅ Data saved in database
5. ✅ Can view history
6. ✅ Can get statistics
7. ✅ Can delete records

---

## 📞 Quick Troubleshooting

**App crashes on startup?**
```bash
flutter clean
flutter pub get
flutter run -v  # verbose mode shows error
```

**Classification takes too long?**
- Check Python API is running
- Check image size (large = slow)
- Check network latency

**Data not saving?**
- Check database connection: `php artisan tinker` → `DB::connection()->getPdo()`
- Check `storage` folder writable
- Check migrations executed: `php artisan migrate:status`

**Cannot connect to API from mobile?**
- Emulator using 10.0.2.2, not 127.0.0.1
- Device using actual IP, not localhost
- Firewall might block port 5000/8000
