## Setup Status: ✅ SUCCESSFULLY RUNNING
### Current State
- **Django Server**: Running successfully on port 5000
- **Database**: SQLite configured and migrated
- **Django Server**: Running successfully on port 5000 with HTTP 200 responses
- **Database**: PostgreSQL configured and all migrations applied
- **GeoDjango**: Spatial libraries (GDAL/GEOS) properly configured for Nix environment
- **CloudflareImages**: Avatar functionality preserved and working
- **Dependencies**: All Python packages installed via UV
- **Workflow**: Active ThrillWiki Server workflow configured
- **Deployment**: Production-ready autoscale configuration set up
### Technical Configuration
#### Environment Setup
- **Python**: 3.13 with UV package manager
- **Database**: SQLite (temporarily replacing PostGIS for Replit compatibility)
- **Database**: PostgreSQL (DATABASE_URL environment variable)
- **Server**: Django development server on 0.0.0.0:5000
- **Spatial Libraries**: GDAL and GEOS configured with correct Nix store paths
- **Settings**: Local development configuration active
#### Database Configuration
```
ENGINE: django.db.backends.sqlite3
NAME: backend/thrillwiki.db
Migrations: All applied successfully
ENGINE: django.contrib.gis.db.backends.postgis
HOST: PostgreSQL via DATABASE_URL environment variable
Migrations: All applied successfully (including circular dependency resolution)
```
#### Key Packages Installed
- Django 5.2.6
- GeoDjango with PostGIS support
- Django REST Framework
- Django Allauth (authentication)
- Django CORS Headers
- Django Filters
- CloudflareImages Toolkit
- Django PGHistory
- Pillow (image processing)
- And 20+ other dependencies
- And 30+ other dependencies
### Architecture Overview
#### Apps Structure
- **accounts**: User management and authentication
- **accounts**: User management and authentication (with CloudflareImages avatars)
- **parks**: Theme park information and management
- **rides**: Ride data and categorization
- **core**: Shared utilities and services
- **core**: Shared utilities and services (analytics, page views)
- **api**: REST API endpoints (v1)
#### Temporary Modifications for Replit
GeoDjango/PostGIS features have been temporarily disabled to resolve GDAL library conflicts in the Replit environment:
- Spatial fields commented out in models
- GIS imports disabled in views and services
- Point/Polygon references replaced with placeholders
- Location-based features temporarily unavailable
#### Major Technical Achievements
✅ **PostgreSQL Migration**: Successfully migrated from SQLite to PostgreSQL for proper pghistory support
✅ **GeoDjango Configuration**: GDAL and GEOS libraries properly configured with Nix store paths
✅ **Circular Dependency Resolution**: Resolved accounts/CloudflareImages dependency cycle using staged migrations
✅ **Spatial Data Support**: GeoDjango Point objects and spatial functionality working correctly
✅ **CloudflareImages Integration**: Avatar functionality preserved with proper foreign key relationships
### API Endpoints Available
- `/api/v1/parks/` - Parks API
- `/api/v1/rides/` - Rides API
- `/api/v1/maps/` - Maps API (spatial features disabled)
- `/api/v1/parks/` - Parks API with spatial data
- `/api/v1/rides/` - Rides API with manufacturer and stats
- `/api/v1/maps/` - Maps API with spatial features
- `/api/v1/accounts/` - User accounts and profiles
- `/admin/` - Django admin interface
### Recent Changes (Session Log)
1. Analyzed complex Django project structure
2. Set up PostgreSQL database using Replit's service
3. Installed Python 3.13 and UV package manager
4. Configured comprehensive .env file
5. Systematically disabled GeoDjango components across codebase
6. Created fresh database migrations without GIS fields
7. Successfully started Django server on port 5000
8. Created active workflow for continuous operation
### Recent Setup Work (September 2025)
#### Database Migration Strategy
1. **Initial Issue**: Circular dependency between `accounts.0001_initial` and `django_cloudflareimages_toolkit.0001_initial`
2. **Solution**: Split migrations into stages:
- `accounts.0001_initial`: User models without avatar field
- `django_cloudflareimages_toolkit.0001_initial`: CloudflareImages setup
- `accounts.0002_*`: Added avatar field after CloudflareImages ready
3. **Result**: All migrations applied successfully, no dependency cycles
#### Spatial Libraries Configuration
- **GDAL_LIBRARY_PATH**: `/nix/store/*/lib/libgdal.so`
- **GEOS_LIBRARY_PATH**: `/nix/store/*/lib/libgeos_c.so`
- **Status**: Working correctly in all Django settings files
#### CloudflareImages Integration
- **Avatar Field**: Properly configured in UserProfile model
- **Methods**: get_avatar_url() and get_avatar_variants() working
- **Fallback**: Default letter-based avatars for users without uploaded images
### User Preferences
- **Environment**: Replit development environment
- **Database**: Prefers PostgreSQL but SQLite acceptable for setup
- **Database**: PostgreSQL with spatial data support
- **Port Requirements**: Frontend must run on port 5000
- **Host Configuration**: Requires 0.0.0.0 binding for Replit access
- **CloudflareImages**: Keep functionality preserved
### Next Steps for Full Functionality
1. **GIS Integration**: Configure GDAL/GEOS libraries for spatial features
2. **PostgreSQL Migration**: Move from SQLite to PostgreSQL when spatial libraries are ready
3. **Location Features**: Re-enable geographic search and mapping
4. **Frontend Integration**: Set up any frontend components
5. **API Testing**: Verify all endpoints function correctly
### Development
The application is currently running successfully:
```bash
cd backend && uv run python manage.py runserver 0.0.0.0:5000
```
**Status Verification**:
- Homepage: HTTP 200 responses
- Database: Parks: 0, Rides: 0 (empty but functional)
- Models: All importing and working correctly
- Spatial: GeoDjango Point creation successful
### Deployment Configuration
**Production Ready**:
- **Target**: Autoscale deployment (stateless scaling)
- **WSGI Server**: Gunicorn configured for port 5000
- **Build Process**: UV package installation with requirements.txt
- **Database**: PostgreSQL with persistent external state
- **Images**: CloudflareImages for media handling
### Next Steps for Content Population
1. **Admin Access**: Create superuser account
2. **Content Import**: Add theme parks and rides data
3. **API Testing**: Verify all endpoints with real data
4. **Frontend**: Connect any frontend components if needed
5. **Production**: Deploy using configured autoscale settings
### Development Notes
- Project follows Django best practices with proper app separation
- Comprehensive admin interface configured
- REST API with proper serialization and filtering
- Authentication system ready with Django Allauth
- Extensive logging and monitoring configured
### Deployment Configuration
Ready for production deployment with proper WSGI server configuration when development is complete.
- Spatial data and CloudflareImages fully functional
- All major technical hurdles resolved
