# ThrillWiki Data Seeding - Implementation Guide

## Overview
This document outlines the specific requirements and implementation steps needed to complete the data seeding script for ThrillWiki. Currently, three features are skipped during seeding due to missing or incomplete model implementations.

## 🛡️ Moderation Data Implementation

### Current Status
```
🛡️  Creating moderation data...
  ✅ Comprehensive moderation system is implemented and ready for seeding
```

### Available Models
The moderation system is fully implemented in `apps.moderation.models` with the following models:

#### 1. ModerationReport Model
```python
class ModerationReport(TrackedModel):
    """Model for tracking user reports about content, users, or behavior"""
    
    STATUS_CHOICES = [
        ('PENDING', 'Pending Review'),
        ('UNDER_REVIEW', 'Under Review'),
        ('RESOLVED', 'Resolved'),
        ('DISMISSED', 'Dismissed'),
    ]
    
    REPORT_TYPE_CHOICES = [
        ('SPAM', 'Spam'),
        ('HARASSMENT', 'Harassment'),
        ('INAPPROPRIATE_CONTENT', 'Inappropriate Content'),
        ('MISINFORMATION', 'Misinformation'),
        ('COPYRIGHT', 'Copyright Violation'),
        ('PRIVACY', 'Privacy Violation'),
        ('HATE_SPEECH', 'Hate Speech'),
        ('VIOLENCE', 'Violence or Threats'),
        ('OTHER', 'Other'),
    ]
    
    report_type = models.CharField(max_length=50, choices=REPORT_TYPE_CHOICES)
    status = models.CharField(max_length=20, choices=STATUS_CHOICES, default='PENDING')
    priority = models.CharField(max_length=10, choices=PRIORITY_CHOICES, default='MEDIUM')
    reason = models.CharField(max_length=200)
    description = models.TextField()
    reported_by = models.ForeignKey(User, on_delete=models.CASCADE, related_name='moderation_reports_made')
    assigned_moderator = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, blank=True)
    # ... additional fields
```

#### 2. ModerationQueue Model
```python
class ModerationQueue(TrackedModel):
    """Model for managing moderation workflow and task assignment"""
    
    ITEM_TYPE_CHOICES = [
        ('CONTENT_REVIEW', 'Content Review'),
        ('USER_REVIEW', 'User Review'),

    ]
    
    item_type = models.CharField(max_length=50, choices=ITEM_TYPE_CHOICES)
    status = models.CharField(max_length=20, choices=STATUS_CHOICES, default='PENDING')
    priority = models.CharField(max_length=10, choices=PRIORITY_CHOICES, default='MEDIUM')
    title = models.CharField(max_length=200)
    description = models.TextField()
    assigned_to = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, blank=True)
    related_report = models.ForeignKey(ModerationReport, on_delete=models.CASCADE, null=True, blank=True)
    # ... additional fields
```

#### 3. ModerationAction Model
```python
class ModerationAction(TrackedModel):
    """Model for tracking actions taken against users or content"""
    
    ACTION_TYPE_CHOICES = [
        ('WARNING', 'Warning'),
        ('USER_SUSPENSION', 'User Suspension'),
        ('USER_BAN', 'User Ban'),
        ('CONTENT_REMOVAL', 'Content Removal'),

    ]
    
    action_type = models.CharField(max_length=50, choices=ACTION_TYPE_CHOICES)
    reason = models.CharField(max_length=200)
    details = models.TextField()
    moderator = models.ForeignKey(User, on_delete=models.CASCADE, related_name='moderation_actions_taken')
    target_user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='moderation_actions_received')
    related_report = models.ForeignKey(ModerationReport, on_delete=models.SET_NULL, null=True, blank=True)
    # ... additional fields
```

#### 4. Additional Models
- **BulkOperation**: For tracking bulk administrative operations
- **PhotoSubmission**: For photo moderation workflow
- **EditSubmission**: For content edit submissions (legacy)

### Implementation Steps

1. **Moderation app already exists** at `backend/apps/moderation/`

2. **Already added to INSTALLED_APPS** in `backend/config/django/base.py`

3. **Models are fully implemented** in `apps/moderation/models.py`

4. **Update the seeding script** - Replace the placeholder in `create_moderation_data()`:
   ```python
   def create_moderation_data(self, users: List[User], parks: List[Park], rides: List[Ride]) -> None:
       """Create moderation reports, queue items, and actions"""
       self.stdout.write('🛡️  Creating moderation data...')
       
       if not users or (not parks and not rides):
           self.stdout.write('  ⚠️  No users or content found, skipping moderation data')
           return
       
       moderators = [u for u in users if u.role in ['MODERATOR', 'ADMIN']]
       if not moderators:
           self.stdout.write('  ⚠️  No moderators found, skipping moderation data')
           return
       
       moderation_count = 0
       all_content = list(parks) + list(rides)
       
       # Create moderation reports
       for _ in range(min(15, len(all_content))):
           content_item = random.choice(all_content)
           reporter = random.choice(users)

           )
           
           # Create queue item for some reports
           if random.random() < 0.6:
               queue_item = ModerationQueue.objects.create(
                   item_type=random.choice(['CONTENT_REVIEW', 'POLICY_VIOLATION']),
                   status=random.choice(['PENDING', 'IN_PROGRESS', 'COMPLETED']),

               )
               
               # Create action if resolved
               if queue_item.status == 'COMPLETED' and moderator:
                   ModerationAction.objects.create(
                       action_type=random.choice(['WARNING', 'CONTENT_EDIT', 'CONTENT_RESTRICTION']),
                       reason=f"Action taken on {content_item.__class__.__name__}",
                       details=f"Moderation action completed for {content_item}",
                       moderator=moderator,

           moderation_count += 1
       
       self.stdout.write(f'  ✅ Created {moderation_count} moderation items')
   ```

## 📸 Photo Records Implementation

### Current Status
```
📸 Creating photo records...
  ✅ Photo system is fully implemented with CloudflareImage integration
```

### Available Models
The photo system is fully implemented with the following models:

#### 1. ParkPhoto Model
```python
class ParkPhoto(TrackedModel):
    """Photo model specific to parks"""
    
    park = models.ForeignKey("parks.Park", on_delete=models.CASCADE, related_name="photos")
    image = models.ForeignKey(
        'django_cloudflareimages_toolkit.CloudflareImage',
        on_delete=models.CASCADE,
        help_text="Park photo stored on Cloudflare Images"
    )
    caption = models.CharField(max_length=255, blank=True)
    alt_text = models.CharField(max_length=255, blank=True)
    is_primary = models.BooleanField(default=False)
    is_approved = models.BooleanField(default=False)
    uploaded_by = models.ForeignKey(User, on_delete=models.SET_NULL, null=True)
    date_taken = models.DateTimeField(null=True, blank=True)
    # ... additional fields with MediaService integration
```

#### 2. RidePhoto Model
```python
class RidePhoto(TrackedModel):
    """Photo model specific to rides"""
    
    ride = models.ForeignKey("rides.Ride", on_delete=models.CASCADE, related_name="photos")
    image = models.ForeignKey(
        'django_cloudflareimages_toolkit.CloudflareImage',
        on_delete=models.CASCADE,
        help_text="Ride photo stored on Cloudflare Images"
    )
    caption = models.CharField(max_length=255, blank=True)
    alt_text = models.CharField(max_length=255, blank=True)
    is_primary = models.BooleanField(default=False)
    is_approved = models.BooleanField(default=False)
    uploaded_by = models.ForeignKey(User, on_delete=models.SET_NULL, null=True)
    
    # Ride-specific metadata
    photo_type = models.CharField(
        max_length=50,
        choices=[
            ("exterior", "Exterior View"),
            ("queue", "Queue Area"),
            ("station", "Station"),

            ("other", "Other"),
        ],
        default="exterior",
    )
    # ... additional fields with MediaService integration
```

### Current Configuration

#### 1. Cloudflare Images Already Configured
The system is already configured in `backend/config/django/base.py`:
```python
# Cloudflare Images Settings
CLOUDFLARE_IMAGES = {
    'ACCOUNT_ID': config("CLOUDFLARE_IMAGES_ACCOUNT_ID"),
    'API_TOKEN': config("CLOUDFLARE_IMAGES_API_TOKEN"),
    'ACCOUNT_HASH': config("CLOUDFLARE_IMAGES_ACCOUNT_HASH"),
    'DEFAULT_VARIANT': 'public',
    'UPLOAD_TIMEOUT': 300,
    'MAX_FILE_SIZE': 10 * 1024 * 1024,  # 10MB
    'ALLOWED_FORMATS': ['jpeg', 'png', 'gif', 'webp'],
    # ... additional configuration
}
```

#### 2. django-cloudflareimages-toolkit Integration
- ✅ Package is installed and configured
- ✅ Models use CloudflareImage foreign keys
- ✅ Advanced MediaService integration exists
- ✅ Custom upload path functions implemented

### Implementation Steps

1. **Photo models already exist** in `apps/parks/models/media.py` and `apps/rides/models/media.py`

2. **CloudflareImage toolkit is installed** and configured

3. **Environment variables needed** (add to `.env`):
   ```env
   CLOUDFLARE_IMAGES_ACCOUNT_ID=your_account_id
   CLOUDFLARE_IMAGES_API_TOKEN=your_api_token
   CLOUDFLARE_IMAGES_ACCOUNT_HASH=your_account_hash
   ```

4. **Update the seeding script** - Replace the placeholder in `create_photos()`:
   ```python
   def create_photos(self, parks: List[Park], rides: List[Ride], users: List[User]) -> None:
       """Create sample photo records using CloudflareImage"""
       self.stdout.write('📸 Creating photo records...')
       
       # For development/testing, we can create placeholder CloudflareImage instances
       # In production, these would be actual uploaded images
       
       photo_count = 0
       
       # Create park photos
       for park in random.sample(parks, min(len(parks), 8)):
           for i in range(random.randint(1, 3)):
               try:

                       is_primary=i == 0,
                       is_approved=True,  # Auto-approve for seeding
                       uploaded_by=random.choice(users),
                       date_taken=timezone.now() - timedelta(days=random.randint(1, 365)),
                   )
                   photo_count += 1
               except Exception as e:
                   self.stdout.write(f'  ⚠️  Failed to create park photo: {str(e)}')
       
       # Create ride photos
       for ride in random.sample(rides, min(len(rides), 15)):
           for i in range(random.randint(1, 2)):
               try:
                   cloudflare_image = CloudflareImage.objects.create(
                       # Add minimal required fields for seeding
                   )
                   
                   RidePhoto.objects.create(
                       ride=ride,
                       image=cloudflare_image,
                       caption=f"Exciting view of {ride.name}",
                       alt_text=f"Photo of {ride.name} ride",
                       photo_type=random.choice(['exterior', 'queue', 'station', 'onride']),
                       is_primary=i == 0,
                       is_approved=True,  # Auto-approve for seeding
                       uploaded_by=random.choice(users),
                       date_taken=timezone.now() - timedelta(days=random.randint(1, 365)),
                   )
                   photo_count += 1
               except Exception as e:
                   self.stdout.write(f'  ⚠️  Failed to create ride photo: {str(e)}')

## 🏆 Ride Rankings Implementation

### Current Status
```
🏆 Creating ride rankings...
  ✅ Advanced ranking system using Internet Roller Coaster Poll algorithm is implemented
```

### Available Models
The ranking system is fully implemented in `apps.rides.models.rankings` with a sophisticated algorithm:

#### 1. RideRanking Model
```python
class RideRanking(models.Model):
    """
    Stores calculated rankings for rides using the Internet Roller Coaster Poll algorithm.
    Rankings are recalculated daily based on user reviews/ratings.
    """
    
    ride = models.OneToOneField("rides.Ride", on_delete=models.CASCADE, related_name="ranking")
    
    # Core ranking metrics
    rank = models.PositiveIntegerField(db_index=True, help_text="Overall rank position (1 = best)")
    wins = models.PositiveIntegerField(default=0, help_text="Number of rides this ride beats in pairwise comparisons")
    losses = models.PositiveIntegerField(default=0, help_text="Number of rides that beat this ride in pairwise comparisons")
    ties = models.PositiveIntegerField(default=0, help_text="Number of rides with equal preference in pairwise comparisons")
    winning_percentage = models.DecimalField(max_digits=5, decimal_places=4, help_text="Win percentage where ties count as 0.5")
    
    # Additional metrics
    mutual_riders_count = models.PositiveIntegerField(default=0, help_text="Total number of users who have rated this ride")
    comparison_count = models.PositiveIntegerField(default=0, help_text="Number of other rides this was compared against")
    average_rating = models.DecimalField(max_digits=3, decimal_places=2, null=True, blank=True)
    
    # Metadata
    last_calculated = models.DateTimeField(default=timezone.now)
    calculation_version = models.CharField(max_length=10, default="1.0")
```

#### 2. RidePairComparison Model
```python
class RidePairComparison(models.Model):
    """
    Caches pairwise comparison results between two rides.
    Used to speed up ranking calculations by storing mutual rider preferences.
    """
    
    ride_a = models.ForeignKey("rides.Ride", on_delete=models.CASCADE, related_name="comparisons_as_a")
    ride_b = models.ForeignKey("rides.Ride", on_delete=models.CASCADE, related_name="comparisons_as_b")
    
    # Comparison results
    ride_a_wins = models.PositiveIntegerField(default=0, help_text="Number of mutual riders who rated ride_a higher")
    ride_b_wins = models.PositiveIntegerField(default=0, help_text="Number of mutual riders who rated ride_b higher")
    ties = models.PositiveIntegerField(default=0, help_text="Number of mutual riders who rated both rides equally")
    
    # Metrics
    mutual_riders_count = models.PositiveIntegerField(default=0, help_text="Total number of users who have rated both rides")
    ride_a_avg_rating = models.DecimalField(max_digits=3, decimal_places=2, null=True, blank=True)
    ride_b_avg_rating = models.DecimalField(max_digits=3, decimal_places=2, null=True, blank=True)
    
    last_calculated = models.DateTimeField(auto_now=True)
```

#### 3. RankingSnapshot Model
```python
class RankingSnapshot(models.Model):
    """
    Stores historical snapshots of rankings for tracking changes over time.
    Allows showing ranking trends and movements.
    """
    
    ride = models.ForeignKey("rides.Ride", on_delete=models.CASCADE, related_name="ranking_history")
    rank = models.PositiveIntegerField()
    winning_percentage = models.DecimalField(max_digits=5, decimal_places=4)
    snapshot_date = models.DateField(db_index=True, help_text="Date when this ranking snapshot was taken")
```

### Algorithm Details

The system implements the **Internet Roller Coaster Poll algorithm**:

1. **Pairwise Comparisons**: Each ride is compared to every other ride based on mutual riders (users who have rated both rides)
2. **Winning Percentage**: Calculated as `(wins + 0.5 * ties) / total_comparisons`
3. **Ranking**: Rides are ranked by winning percentage, with ties broken by mutual rider count
4. **Daily Recalculation**: Rankings are updated daily to reflect new reviews and ratings

### Implementation Steps

1. **Ranking models already exist** in `apps/rides/models/rankings.py`

2. **Models are fully implemented** with sophisticated algorithm

3. **Update the seeding script** - Replace the placeholder in `create_rankings()`:
   ```python
   def create_rankings(self, rides: List[Ride], users: List[User]) -> None:

       snapshot_count = 0
       
       # Create initial rankings for all rides
       for i, ride in enumerate(rides, 1):
           # Calculate mock metrics for seeding
           mock_wins = random.randint(0, len(rides) - 1)
           mock_losses = random.randint(0, len(rides) - 1 - mock_wins)
           mock_ties = len(rides) - 1 - mock_wins - mock_losses
           total_comparisons = mock_wins + mock_losses + mock_ties
           
           winning_percentage = (mock_wins + 0.5 * mock_ties) / total_comparisons if total_comparisons > 0 else 0.5
           
           RideRanking.objects.create(
               ride=ride,
               rank=i,  # Will be recalculated based on winning_percentage
