# 🏭 ThrillWiki Manufacturer Model & System Implementation

**PRIORITY 1: Create Manufacturer Model & System - Production-Ready Implementation**

## 🎯 **MISSION: CRITICAL ENTITY ARCHITECTURE IMPLEMENTATION**

You are implementing the **Manufacturer entity** for ThrillWiki - a critical architectural component that represents ride building companies (Intamin, B&M, Vekoma) and establishes proper entity separation from theme park Operators.

## 🏗️ **ARCHITECTURAL CONTEXT**

### **CRITICAL ENTITY SEPARATION ACHIEVED**
This implementation resolves a major architectural conflict where "Operator" was incorrectly handling both park ownership AND ride manufacturing responsibilities.

**CORRECTED ARCHITECTURE**:
- ✅ **Operator**: Theme park companies (Disney, Six Flags) - manages `parks()` only
- ✅ **Manufacturer**: Ride building companies (Intamin, B&M) - has `rides()` as manufacturer  
- ✅ **Designer**: Individual designers (Werner Stengel) - has `rides()` as designer

## 📊 **DATABASE FOUNDATION - ALREADY EXISTS**

**Migration**: `database/migrations/2024_02_23_234948_create_operators_and_manufacturers_tables.php`
**Status**: ✅ **Table exists** - Focus on model implementation and relationships

**Key Fields**:
- `id`, `name`, `slug`, `website`, `headquarters`, `description`
- `total_rides`, `total_roller_coasters` (cached statistics)
- `is_active`, `created_at`, `updated_at`, `deleted_at`
- **Indexes**: PRIMARY(`id`), UNIQUE(`slug`), INDEX(`is_active`, `total_rides`, `deleted_at`)

## 🚀 **IMPLEMENTATION COMMAND**

```bash
php artisan make:thrillwiki-model Manufacturer --migration --factory --with-relationships --cached --api-resource --with-tests
```

**Expected Results**: Model with HasSlugHistory trait, proper relationships, factory, tests, API resource

## 🔧 **REQUIRED MODEL SPECIFICATIONS**

### **Traits Integration**
- ✅ **HasFactory**: Laravel factory integration
- ✅ **HasSlugHistory**: ThrillWiki slug management (CRITICAL for proper entity behavior)
- ✅ **SoftDeletes**: Standard soft delete functionality

### **Key Relationships**
```php
// PRIMARY RELATIONSHIP - Rides manufactured by this company
public function rides(): HasMany
{
    return $this->hasMany(Ride::class, 'manufacturer_id');
}
```

### **Business Logic Methods**
```php
// Statistics updates for performance optimization
public function updateStatistics(): void

// Display helpers
public function getDisplayNameAttribute(): string
public function getWebsiteUrlAttribute(): string
```

### **Query Scopes**
```php
// Major manufacturers filter
public function scopeMajorManufacturers($query, int $minRides = 5)

// Coaster manufacturers filter  
public function scopeCoasterManufacturers($query)
```

### **Route Model Binding**
```php
public function getRouteKeyName(): string
{
    return 'slug'; // Use slug for URL routing
}
```

## ⚡ **CRITICAL SUCCESS FACTORS**

### **98% Development Speed Achievement**
- **Custom Generator**: Leverages ThrillWiki's proven acceleration framework
- **Time Savings**: 1-4 seconds vs 30-45 minutes manual implementation
- **Pattern Compliance**: Automatic ThrillWiki standard integration

### **Django Parity Verification**
- **Architecture Match**: Aligns with original Django implementation structure
- **Field Compatibility**: Maintains identical data structures
- **Business Logic**: Preserves original functionality patterns

### **Performance Optimization Built-In**
- **Caching Integration**: Automatic statistics caching (`total_rides`, `total_roller_coasters`)
- **Query Optimization**: Pre-built scopes for common queries
- **Database Indexes**: Optimized for filtering and search operations

## 🧪 **TESTING REQUIREMENTS**

### **Generated Test Coverage**
- ✅ **Model Tests**: Factory creation, relationships, business logic
- ✅ **Relationship Tests**: Proper manufacturer-ride associations
- ✅ **Scope Tests**: Query scope functionality verification
- ✅ **Statistics Tests**: Cache update functionality

### **Validation Tests**
```php
// Test proper entity separation
$manufacturer = Manufacturer::factory()->create();
$ride = Ride::factory()->create(['manufacturer_id' => $manufacturer->id]);
$this->assertEquals($manufacturer->id, $ride->manufacturer->id);

// Test statistics functionality
$manufacturer->updateStatistics();
$this->assertEquals(1, $manufacturer->total_rides);
```

## 🎯 **IMPLEMENTATION VERIFICATION**

### **Post-Generation Checklist**
1. ✅ **Model Generated**: `app/Models/Manufacturer.php` with proper traits
2. ✅ **Factory Created**: `database/factories/ManufacturerFactory.php` 
3. ✅ **Tests Generated**: `tests/Feature/ManufacturerTest.php`
4. ✅ **API Resource**: `app/Http/Resources/ManufacturerResource.php`
5. ✅ **Relationships**: Proper `rides()` hasMany relationship

### **Architecture Validation**
```php
// Verify entity separation works correctly
$intamin = Manufacturer::create(['name' => 'Intamin AG', 'slug' => 'intamin']);
$ride = Ride::create([
    'name' => 'Millennium Force',
    'manufacturer_id' => $intamin->id, // CORRECT: Manufacturer builds rides
    'park_id' => $park->id
]);

$operator = Operator::create(['name' => 'Cedar Fair', 'slug' => 'cedar-fair']);
$park = Park::create([
    'name' => 'Cedar Point',
    'operator_id' => $operator->id // CORRECT: Operator owns parks
]);
```

## 📚 **DOCUMENTATION UPDATE REQUIREMENTS**

### **Memory Bank Updates**
- ✅ Update `progress.md` with implementation completion
- ✅ Update `activeContext.md` with next steps
- ✅ Document any generator customizations needed

### **Entity Documentation**
- ✅ Complete manufacturer relationship documentation
- ✅ Update ride model relationship references
- ✅ Verify operator entity scope clarification

## 🏆 **SUCCESS METRICS**

### **Performance Targets**
- **Generation Time**: < 5 seconds total execution
- **Test Coverage**: 100% model functionality
- **Memory Usage**: Optimized for high-volume manufacturer queries

### **Quality Assurance**
- **Code Standards**: PSR-12 compliant generated code
- **Laravel Conventions**: Proper Eloquent model patterns
- **ThrillWiki Patterns**: Consistent with project architecture

## 🚀 **EXECUTION COMMAND**

**READY TO EXECUTE**:
```bash
php artisan make:thrillwiki-model Manufacturer --migration --factory --with-relationships --cached --api-resource --with-tests
```

**Expected Outcome**: Complete, production-ready Manufacturer entity with proper architecture separation, performance optimization, comprehensive testing, and Django parity compliance.

**Next Steps After Success**: Proceed to CRUD system generation and Ride model relationship updates.
