# Reviews System Architecture Plan
**Date**: June 21, 2025  
**Status**: 🎯 **PRIORITY 2 TASK - ARCHITECTURE PLANNING PHASE**

## 🚨 CRITICAL DISCOVERY: Architecture Gap Analysis

### **Current Implementation vs Django Parity Requirements**

**MAJOR FINDING**: The current Laravel implementation has a **fundamental architectural mismatch** with the Django reference implementation that must be resolved to achieve Django parity.

### **Django Implementation Analysis**
Based on analysis of `//Volumes/macminissd/Projects/thrillwiki_django_no_react/reviews/models.py`:

**Django Architecture**:
- **Generic Reviews**: Uses ContentType + GenericForeignKey for polymorphic relationships
- **Review Model**: Can review ANY entity (rides, parks, etc.) through `content_type` + `object_id`
- **Rating Scale**: 1-10 (not 1-5 as currently implemented)
- **Required Fields**: `title`, `visit_date` (both required in Django)
- **Additional Models**:
  - `ReviewImage`: Attached images to reviews
  - `ReviewLike`: Like/helpful vote system  
  - `ReviewReport`: Moderation reporting system
- **Advanced Features**: Photo uploads, moderation workflow, reporting system

**Current Laravel Implementation**:
- **Rigid Reviews**: Uses `reviewable_type` + `reviewable_id` morphTo relationship
- **Limited Scope**: Only set up for Ride reviews currently
- **Rating Scale**: 1-5 (incorrect scale)
- **Optional Fields**: `title` and `visit_date` are optional (should be required)
- **Missing Models**: No ReviewImage, ReviewLike, or ReviewReport equivalents
- **Incomplete Features**: No photo uploads, limited moderation, no reporting

### **Critical Architecture Decisions Required**

## ✅ ARCHITECTURAL DECISIONS

### **1. Database Schema Architecture**
**Decision**: Implement Django-compatible polymorphic review system

**Schema Requirements**:
```sql
-- Core Review Table (Django Parity)
reviews:
  - id (primary key)
  - content_type_id (foreign key) -- Enables polymorphic reviews
  - object_id (integer) -- ID of reviewed entity
  - user_id (foreign key to users)
  - rating (integer 1-10) -- Match Django scale
  - title (string, required) -- Match Django requirement
  - content (text, required)
  - visit_date (date, required) -- Match Django requirement
  - is_published (boolean, default true)
  - moderation_notes (text, nullable)
  - moderated_by_id (foreign key to users, nullable)
  - moderated_at (timestamp, nullable)
  - created_at (timestamp)
  - updated_at (timestamp)

-- Review Images (Django Parity)
review_images:
  - id (primary key)
  - review_id (foreign key to reviews)
  - image_path (string) -- Store image file path
  - caption (string, optional)
  - order (integer, default 0)
  - created_at (timestamp)

-- Review Likes/Helpful Votes (Django Parity)
review_likes:
  - id (primary key)
  - review_id (foreign key to reviews)
  - user_id (foreign key to users)
  - created_at (timestamp)
  - UNIQUE(review_id, user_id)

-- Review Reports (Django Parity)
review_reports:
  - id (primary key)
  - review_id (foreign key to reviews)
  - user_id (foreign key to users)
  - reason (text, required)
  - resolved (boolean, default false)
  - resolved_by_id (foreign key to users, nullable)
  - resolution_notes (text, nullable)
  - resolved_at (timestamp, nullable)
  - created_at (timestamp)
```

### **2. Entity Integration Strategy**
**Decision**: Support reviews for multiple entity types (Parks, Rides, potentially Operators)

**Supported Reviewable Entities**:
1. **Rides** (Primary) - Individual ride experiences
2. **Parks** (Secondary) - Overall park experiences  
3. **Future**: Operators, Areas, Events

**Implementation Approach**:
- Laravel's `morphTo`/`morphMany` relationships for polymorphic associations
- Reviewable trait for consistent interface across entities
- Centralized review logic in Review model

### **3. Component Architecture Strategy**
**Decision**: Reusable component system with entity-specific customization

**Core Livewire Components**:

1. **ReviewFormComponent** (Reusable)
   - Generic review creation/editing
   - Entity-agnostic design
   - Configurable for different reviewable types
   - Real-time validation
   - Image upload support

2. **ReviewListComponent** (Reusable)  
   - Generic review display
   - Pagination, sorting, filtering
   - Entity-agnostic design
   - Helpful vote functionality
   - Moderation actions (admin)

3. **ReviewModerationComponent** (Admin)
   - Cross-entity review moderation
   - Batch operations
   - Report management
   - Statistics dashboard

4. **Entity-Specific Integrations**:
   - `RideReviewSection` - Integrates with ride detail pages
   - `ParkReviewSection` - Integrates with park detail pages
   - `ReviewWidgets` - Reusable review display widgets

### **4. Performance Strategy**
**Decision**: Multi-layer caching with real-time statistics

**Caching Architecture**:
- **Model Caching**: Cache review aggregates (average rating, count)
- **Query Caching**: Cache expensive review queries
- **Statistics Caching**: Cache review statistics per entity
- **Real-time Updates**: Livewire for immediate UI feedback

**Performance Optimizations**:
- Eager loading with `with()` for relationships
- Database indexes on frequently queried fields
- Pagination for large review sets
- Image optimization for review photos

### **5. Generator Integration Strategy**
**Decision**: Leverage ThrillWiki custom generators for rapid development

**Generator Commands for Reviews**:
```bash
# Create Review system models
php artisan make:thrillwiki-model Review --migration --factory --with-relationships --cached --api-resource --with-tests
php artisan make:thrillwiki-model ReviewImage --migration --with-relationships --with-tests
php artisan make:thrillwiki-model ReviewLike --migration --with-relationships --with-tests  
php artisan make:thrillwiki-model ReviewReport --migration --with-relationships --with-tests

# Create review components
php artisan make:thrillwiki-livewire ReviewFormComponent --reusable --with-tests --cached
php artisan make:thrillwiki-livewire ReviewListComponent --reusable --with-tests --cached --paginated
php artisan make:thrillwiki-livewire ReviewModerationComponent --with-tests

    public function reviewable(): MorphTo
    
    // Standard relationships  
    public function user(): BelongsTo
    public function moderator(): BelongsTo
    public function images(): HasMany
    public function likes(): HasMany
    public function reports(): HasMany
}
