+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Development Commands
+
+### Running the Application
+```bash
+# Start development server (for local development)
+python manage.py runserver
+
+# Start with uvicorn (production-like)
+uvicorn mysite.asgi:application --host=0.0.0.0 --port=8000 --reload
+```
+
+### Database Operations
+```bash
+# Run migrations
+python manage.py makemigrations
+python manage.py migrate
+
+# Create superuser
+python manage.py createsuperuser
+```
+
+### Docker Development
+```bash
+# Build Docker image
+docker build -t my-django:latest .
+
+# Run with Docker Compose (see deploy/compose-test.yaml)
+docker-compose -f deploy/compose-test.yaml up -d
+```
+
+### Testing
+```bash
+# Run tests
+python manage.py test
+
+# Run tests for specific app
+python manage.py test apps.role
+```
+
+## Architecture Overview
+
+### Project Structure
+This is a Django 5.1 REST API project with the following key components:
+
+- **mysite/**: Main Django project configuration
+- **apps/**: Modular Django applications
+  - `area/`: Geographic area management
+  - `dictionary/`: Data dictionary/configuration
+  - `menu/`: Navigation menu system
+  - `menu_button/`: Menu button permissions
+  - `role/`: Role-based access control
+  - `system_user/`: User management
+- **utils/**: Shared utilities and middleware
+
+### Key Configuration Details
+
+#### Database Setup
+- **Primary Database**: MySQL (host: 47.108.232.131:3306, database: ky)
+- **Secondary Database**: MongoDB (host: 47.108.232.131:27017, database: wk)
+- **Caching**: Redis with multiple databases (0: default, 1: queue, 2: base, 3: cache)
+
+#### REST Framework Configuration
+- Uses Django REST Framework 3.15.2
+- JSON response format with custom response wrapper
+- Exception handling via `utils.exception.CustomExceptionMiddleware`
+- Filtering support via django-filter
+- API documentation with CoreAPI
+
+#### Internationalization
+- Primary language: Chinese (zh-hans)
+- Timezone: Asia/Shanghai
+- Localization support enabled
+
+### API Structure
+All APIs follow the pattern:
+- `/area/` - Area management endpoints
+- `/role/` - Role management endpoints
+- `/menu/` - Menu management endpoints
+- `/menu_button/` - Menu button endpoints
+- `/dictionary/` - Dictionary endpoints
+- `/system_user/` - User management endpoints
+
+### Custom Utilities
+- `utils.json_response.Response`: Standardized API response wrapper
+- `utils.exception.CustomExceptionMiddleware`: Global exception handling
+- `utils.paginator`: Custom pagination logic
+- `utils.redis`: Redis connection utilities
+
+### Deployment
+- Containerized with Docker (Python 3.11-slim base)
+- Uses uvicorn ASGI server
+- CI/CD via GitHub Actions with self-hosted runners
+- Deployment to test environment via Docker Compose
+
+## Development Notes
+
+### Dependencies
+- Core: Django 5.1.5, Django REST Framework 3.15.2
+- Database: PyMySQL, mongoengine
+- Caching: django-redis
+- Server: uvicorn
+
+### Security Considerations
+- CSRF middleware is disabled (line 55 in settings.py)
+- Custom exception middleware catches all unhandled exceptions
+- Debug mode enabled (should be disabled in production)
+
+### Logging
+- Comprehensive logging setup with rotation
+- Separate log files for general logs and error logs
+- File-based logging with console output for development
