# ThrillWiki REST API Guide

## Phase 2B: REST API Development - Complete

This guide provides comprehensive documentation for the ThrillWiki REST API v1.

## Overview

The ThrillWiki API provides programmatic access to amusement park, ride, and company data. It uses django-ninja for fast, modern REST API implementation with automatic OpenAPI documentation.

## Base URL

- **Local Development**: `http://localhost:8000/api/v1/`
- **Production**: `https://your-domain.com/api/v1/`

## Documentation

- **Interactive API Docs**: `/api/v1/docs`
- **OpenAPI Schema**: `/api/v1/openapi.json`

## Features

### Implemented in Phase 2B

✅ **Full CRUD Operations** for all entities
✅ **Filtering & Search** on all list endpoints
✅ **Pagination** (50 items per page)
✅ **Geographic Search** for parks (dual-mode: SQLite + PostGIS)
✅ **Automatic OpenAPI/Swagger Documentation**
✅ **Pydantic Schema Validation**
✅ **Related Data** (automatic joins and annotations)
✅ **Error Handling** with detailed error responses

### Coming in Phase 2C

- JWT Token Authentication
- Role-based Permissions
- Rate Limiting
- Caching
- Webhooks

## Authentication

**Current Status**: Authentication placeholders are in place, but not yet enforced.

- **Read Operations (GET)**: Public access
- **Write Operations (POST, PUT, PATCH, DELETE)**: Will require authentication (JWT tokens)

# Get API info
curl http://localhost:8000/api/v1/info

# List companies
curl http://localhost:8000/api/v1/companies/

# Search parks
curl "http://localhost:8000/api/v1/parks/?search=Six+Flags"

# Find nearby parks
curl "http://localhost:8000/api/v1/parks/nearby/?latitude=28.385&longitude=-81.563&radius=50"
```

### Using the Interactive Docs

1. Start the development server:
   ```bash
   cd django
   python manage.py runserver
   ```

2. Open your browser to:
   ```
   http://localhost:8000/api/v1/docs
   ```

3. Explore and test all endpoints interactively!

## Geographic Features

### SQLite Mode (Local Development)

Uses simple latitude/longitude fields with bounding box approximation:
- Stores coordinates as `DecimalField`
- Geographic search uses bounding box calculation
- Less accurate but works without PostGIS

### PostGIS Mode (Production)

Uses advanced geographic features:
- Stores coordinates as `PointField` (geography type)
- Accurate distance-based queries
- Supports spatial indexing
- Full GIS capabilities

### Switching Between Modes

The API automatically detects the database backend and uses the appropriate method. No code changes needed!

## Next Steps

### Phase 2C: Admin Interface Enhancements
- Enhanced Django admin for all entities
- Bulk operations
- Advanced filtering
- Custom actions

### Phase 3: Frontend Integration
- React/Next.js frontend
- Real-time updates
- Interactive maps
- Rich search interface

### Phase 4: Advanced Features
- JWT authentication
- API rate limiting
- Caching strategies
- Webhooks
- WebSocket support
