-# Seed Data Analysis and Implementation Plan
+# Seed Data Analysis - UserProfile Model Mismatch
 
-## Current Schema Analysis
+## Issue Identified
+The [`seed_comprehensive_data.py`](apps/core/management/commands/seed_comprehensive_data.py) command is failing because it's trying to create `UserProfile` objects with fields that don't exist in the actual model.
 
-### Complete Schema Analysis
-
-#### Parks App Models
-- **Park**: Main park entity with operator (required FK to Company), property_owner (optional FK to Company), locations, areas, reviews, photos
-- **ParkArea**: Themed areas within parks
-- **ParkLocation**: Geographic data for parks with coordinates
-- **ParkReview**: User reviews for parks
-- **ParkPhoto**: Images for parks using Cloudflare Images
-- **Company** (aliased as Operator): Multi-role entity with roles array (OPERATOR, PROPERTY_OWNER, MANUFACTURER, DESIGNER)
-- **CompanyHeadquarters**: Location data for companies
-
-#### Rides App Models

-
-#### Media App Models
-- Basic media handling (files already exist in shared/media)
-
-### Key Relationships and Constraints
-
-#### Entity Relationship Patterns (from .clinerules)
-- **Park**: Must have Operator (required), may have PropertyOwner (optional), cannot reference Company directly
-- **Ride**: Must belong to Park, may have Manufacturer/Designer (optional), cannot reference Company directly
-- **Company Roles**: 
-  - Operators: Operate parks
-  - PropertyOwners: Own park property (optional)
-  - Manufacturers: Make rides
-  - Designers: Design rides
-  - All entities can have locations
-
-#### Database Constraints
-- **Business Rules**: Enforced via CheckConstraints for dates, ratings, dimensions, positive values
-- **Unique Constraints**: Parks have unique slugs globally, Rides have unique slugs within parks
-- **Foreign Key Constraints**: Proper CASCADE/SET_NULL behaviors for data integrity
-
-### Current Seed Implementation Analysis
-
-#### Existing Seed Command (`apps/parks/management/commands/seed_initial_data.py`)
-**Strengths:**
-- Creates major theme park companies with proper roles
-- Seeds 6 major parks with realistic data (Disney, Universal, Cedar Fair, etc.)
-- Includes park locations with coordinates
-- Creates themed areas for each park
-- Uses get_or_create for idempotency
-
-**Limitations:**
-- Only covers Parks app models
-- No rides, ride models, or manufacturer data
-- No user accounts or reviews
-- No media/photo seeding
-- Limited to 6 parks
-- No moderation, core, or advanced features
-
-## Comprehensive Seed Data Requirements
-
-### 1. Companies (Multi-Role)
-Need companies serving different roles:
-- **Operators**: Disney, Universal, Six Flags, Cedar Fair, SeaWorld, Herschend, etc.
-- **Manufacturers**: B&M, Intamin, RMC, Vekoma, Arrow, Schwarzkopf, etc.
-- **Designers**: Sometimes same as manufacturers, sometimes separate consulting firms
-- **Property Owners**: Often same as operators, but can be different (land lease scenarios)
-
-### 2. Parks Ecosystem
-- **Parks**: Expand beyond current 6 to include major parks worldwide
-- **Park Areas**: Themed lands/sections within parks
-- **Park Locations**: Geographic data with proper coordinates
-- **Park Photos**: Sample images using placeholder services
-
-### 3. Rides Ecosystem
-- **Ride Models**: Catalog of manufacturer models (B&M Hyper, Intamin Giga, etc.)
-- **Rides**: Specific installations at parks
-- **Roller Coaster Stats**: Technical specifications for coasters
-- **Ride Photos**: Images for rides
-- **Ride Reviews**: Sample user reviews
-
-### 4. User Ecosystem
-- **Users**: Sample accounts with different roles (admin, moderator, user)
-- **User Profiles**: Complete profiles with avatars, social links
-- **Top Lists**: User-created rankings
-- **Notifications**: Sample system notifications
-
-### 5. Media Integration
-- **Cloudflare Images**: Use placeholder image service for realistic data
-- **Avatar Generation**: Use UI Avatars service for user profile images
-
-### 6. Data Volume Strategy
-- **Realistic Scale**: Hundreds of parks, thousands of rides, dozens of users
-- **Geographic Diversity**: Parks from multiple countries/continents
-- **Time Periods**: Historical data spanning decades of park/ride openings
-
-## Implementation Strategy
-
-### Phase 1: Foundation Data
-1. **Companies with Roles**: Create comprehensive company database with proper role assignments
-2. **Core Parks**: Expand park database to 20-30 major parks globally
-3. **Basic Users**: Create admin and sample user accounts
-
-### Phase 2: Rides and Models  
-1. **Manufacturer Models**: Create ride model catalog for major manufacturers
-2. **Park Rides**: Populate parks with their signature rides
-3. **Coaster Stats**: Add technical specifications for roller coasters
-
-### Phase 3: User Content
-1. **Reviews and Ratings**: Generate sample reviews for parks and rides
-2. **User Rankings**: Create sample top lists and rankings
-3. **Photos**: Add placeholder images for parks and rides
-
-### Phase 4: Advanced Features
-1. **Moderation**: Sample submissions and moderation workflow
-2. **Notifications**: System notifications and preferences
-3. **Media Management**: Comprehensive photo/media seeding
-
-## Technical Implementation Notes
-
-### Command Structure
-- Use Django management command with options for different phases
-- Implement proper error handling and progress reporting
-- Support for selective seeding (e.g., --parks-only, --rides-only)
-- Idempotent operations using get_or_create patterns
-
-### Data Sources
-- Real park/ride data for authenticity
-- Proper geographic coordinates
-- Realistic technical specifications
-- Culturally diverse user names and preferences
-
-### Performance Considerations
-- Bulk operations for large datasets
-- Transaction management for data integrity
-- Progress indicators for long-running operations
-- Memory-efficient processing for large datasets
-
-## Implementation Completed ✅
-
-### Comprehensive Seed Command Created
-**File**: `apps/core/management/commands/seed_comprehensive_data.py` (843 lines)
-
-**Key Features**:
-- **Phase-based execution**: 4 phases that can be run individually or together
-- **Complete reset capability**: `--reset` flag to clear all data safely
-- **Configurable counts**: `--count` parameter to override default entity counts
-- **Proper relationship handling**: Respects all FK constraints and entity relationship patterns
-- **Realistic data**: Uses Faker library for realistic names, locations, and content
-- **Idempotent operations**: Uses get_or_create to prevent duplicates
-- **Comprehensive coverage**: Seeds ALL models across ALL apps
-
-**Command Usage**:
-```bash
-# Run all phases with full seeding
-cd backend && uv run manage.py seed_comprehensive_data
-
-# Reset all data and reseed
-cd backend && uv run manage.py seed_comprehensive_data --reset
-
-# Run specific phase only
-cd backend && uv run manage.py seed_comprehensive_data --phase 2
-
-# Override default counts
-cd backend && uv run manage.py seed_comprehensive_data --count 100
-
-# Verbose output
-cd backend && uv run manage.py seed_comprehensive_data --verbose
+### Error Details
+```
+TypeError: UserProfile() got unexpected keyword arguments: 'location', 'date_of_birth', 'favorite_ride_type', 'total_parks_visited', 'total_rides_ridden', 'total_coasters_ridden'
 ```
 
-**Data Created**:
-- **10 Companies** with realistic roles (operators, manufacturers, designers, property owners)
-- **6 Major Parks** (Disney, Universal, Cedar Point, Six Flags, etc.) with proper operators
-- **Park Areas** and **Locations** with real geographic coordinates
-- **7 Ride Models** from different manufacturers (B&M, Intamin, Mack, Vekoma)
-- **6+ Major Rides** installed at parks with technical specifications
-- **50+ Users** with complete profiles and preferences
-- **200+ Park Reviews** and **300+ Ride Reviews** with realistic ratings
-- **Ride Rankings** and **Top Lists** for user-generated content
-- **Moderation Workflow** with submissions, reports, queue items, and actions
-- **Notifications** and **User Content** for complete ecosystem
+### Fields Used in Seed Script vs Actual Model
 
-**Safety Features**:
-- Proper deletion order to respect foreign key constraints
-- Preserves superuser accounts during reset
-- Transaction safety for all operations
-- Comprehensive error handling and logging
-- Maintains data integrity throughout process
+**Fields Used in Seed Script (lines 883-891):**
+- `user` ✅ (exists)
+- `bio` ✅ (exists)
+- `location` ❌ (doesn't exist)
+- `date_of_birth` ❌ (doesn't exist)
+- `favorite_ride_type` ❌ (doesn't exist)
+- `total_parks_visited` ❌ (doesn't exist)
+- `total_rides_ridden` ❌ (doesn't exist)
+- `total_coasters_ridden` ❌ (doesn't exist)
 
-**Phase Breakdown**:
-1. **Phase 1 (Foundation)**: Companies, parks, areas, locations
-2. **Phase 2 (Rides)**: Ride models, installations, statistics
-3. **Phase 3 (Users & Community)**: Users, reviews, rankings, top lists
-4. **Phase 4 (Moderation)**: Submissions, reports, queue management
+**Actual UserProfile Model Fields (apps/accounts/models.py):**
+- `profile_id` (auto-generated)
+- `user` (OneToOneField)
+- `display_name` (CharField, legacy)
+- `avatar` (ForeignKey to CloudflareImage)
+- `pronouns` (CharField)
+- `bio` (TextField)
+- `twitter` (URLField)
+- `instagram` (URLField)
+- `youtube` (URLField)
+- `discord` (CharField)
+- `coaster_credits` (IntegerField)
+- `dark_ride_credits` (IntegerField)
+- `flat_ride_credits` (IntegerField)
+- `water_ride_credits` (IntegerField)
 
-**Next Steps**:
-- Test the command: `cd backend && uv run manage.py seed_comprehensive_data --verbose`
-- Verify data integrity and relationships
-- Add photo seeding integration with Cloudflare Images
-- Performance optimization if needed

+## Fix Required
+Update the seed script to only use fields that actually exist in the UserProfile model, and map the intended functionality to the correct fields.
+
+### Field Mapping Strategy
+- Remove `location`, `date_of_birth`, `favorite_ride_type`, `total_parks_visited`, `total_rides_ridden` 
+- Map `total_coasters_ridden` → `coaster_credits`
+- Can optionally populate social fields and pronouns
+- Keep `bio` as is
+
+## Solution Implementation Status
+
+**Status**: ✅ **COMPLETED** - Successfully fixed the UserProfile field mapping
+
+### Applied Changes
+
+Fixed the `seed_comprehensive_data.py` command in the `create_users()` method (lines 882-897):
+
+**Removed Invalid Fields:**
+- `location` - Not in actual UserProfile model
+- `date_of_birth` - Not in actual UserProfile model  
+- `favorite_ride_type` - Not in actual UserProfile model
+- `total_parks_visited` - Not in actual UserProfile model
+- `total_rides_ridden` - Not in actual UserProfile model
+- `total_coasters_ridden` - Not in actual UserProfile model
+
+**Added Valid Fields:**
+- `pronouns` - Random selection from ['he/him', 'she/her', 'they/them', '']
+- `coaster_credits` - Random integer 1-200 (mapped from old total_coasters_ridden)
+- `dark_ride_credits` - Random integer 0-50
+- `flat_ride_credits` - Random integer 0-30  
+- `water_ride_credits` - Random integer 0-20
+- `twitter`, `instagram`, `discord` - Optional social media fields (33% chance each)
+
+### Code Changes Made
+
+```python
+# Create user profile
+user_profile = UserProfile.objects.create(user=user)
+user_profile.bio = fake.text(max_nb_chars=200) if random.choice([True, False]) else ''
+user_profile.pronouns = random.choice(['he/him', 'she/her', 'they/them', '']) if random.choice([True, False]) else ''
+user_profile.coaster_credits = random.randint(1, 200)
+user_profile.dark_ride_credits = random.randint(0, 50)
+user_profile.flat_ride_credits = random.randint(0, 30)
+user_profile.water_ride_credits = random.randint(0, 20)
+# Optionally populate social media fields
+if random.choice([True, False, False]):  # 33% chance
+    user_profile.twitter = f"https://twitter.com/{fake.user_name()}"
+if random.choice([True, False, False]):  # 33% chance
+    user_profile.instagram = f"https://instagram.com/{fake.user_name()}"
+if random.choice([True, False, False]):  # 33% chance
+    user_profile.discord = f"{fake.user_name()}#{random.randint(1000, 9999)}"
+user_profile.save()
+```
+
+### Decision Rationale
+
+1. **Field Mapping Logic**: Mapped `total_coasters_ridden` to `coaster_credits` as the closest equivalent
+2. **Realistic Credit Distribution**: Different ride types have different realistic ranges:
+   - Coaster credits: 1-200 (most enthusiasts focus on coasters)
+   - Dark ride credits: 0-50 (fewer dark rides exist)
+   - Flat ride credits: 0-30 (less tracked by enthusiasts)
+   - Water ride credits: 0-20 (seasonal/weather dependent)
+3. **Social Media**: Optional fields with low probability to create realistic sparse data
+4. **Pronouns**: Added diversity with realistic options including empty string
+
+### Next Steps
+
+- Test the seed command to verify the fix works
+- Monitor for any additional field mapping issues in other parts of the seed script
