## Quick Start

1. Install the plugin:
```bash
pip install cesnet_service_path_plugin
```

2. Enable the plugin in your NetBox configuration:
```python
PLUGINS = [
    'cesnet_service_path_plugin'
]

PLUGINS_CONFIG = {
    "cesnet_service_path_plugin": {},
}
```

3. Run NetBox migrations:
```bash
python manage.py migrate
```

4. **Configure GeoDjango** (required for geographic features):
   - Install GDAL, GEOS, and PROJ libraries
   - Configure PostGIS extension in PostgreSQL
   - See [GeoDjango installation guide](https://docs.djangoproject.com/en/stable/ref/contrib/gis/install/)

## Installation

### Prerequisites

For geographic features, you need:
- **PostGIS-enabled PostgreSQL database**
- **GDAL, GEOS, and PROJ libraries**
- **Python packages**: `geopandas`, `fiona`, `shapely`

### Using pip
```bash
pip install cesnet_service_path_plugin
```

### Using Docker
For NetBox Docker installations, add to your `plugin_requirements.txt`:
```bash
cesnet_service_path_plugin
```

**Docker users**: Ensure your NetBox Docker image includes PostGIS and GDAL libraries.

For detailed Docker setup instructions, see [using netbox-docker with plugins](https://github.com/netbox-community/netbox-docker/wiki/Using-Netbox-Plugins).

## Configuration

### Database Configuration

Ensure your NetBox database has PostGIS enabled:
```sql
CREATE EXTENSION IF NOT EXISTS postgis;
```

### Custom Status Choices

Extend or override default status choices in your `configuration.py`:

```python
FIELD_CHOICES = {
    'cesnet_service_path_plugin.choices.status': (
        ('custom_status', 'Custom Status', 'blue'),
        # ('status_value', 'Display Name', 'color'),
    )
}
```

Status choice format:
- Value: Internal database value
- Name: UI display name
- Color: Badge color (blue, green, red, orange, yellow, purple, gray)

Default statuses (Active, Planned, Offline) will be merged with custom choices.

### Custom Kind Choices

Extend or override default kind choices in your `configuration.py`:

```python
FIELD_CHOICES = {
    'cesnet_service_path_plugin.choices.kind': (
        ('custom_kind', 'Custom Kind Name', 'purple'),
        # ('kind_value', 'Display Name', 'color'),
    )
}
```

Kind choice format:
- Value: Internal database value
- Name: UI display name
- Color: Badge color (blue, green, red, orange, yellow, purple, gray)

Default kinds:
- experimental: Experimentální (cyan)
- core: Páteřní (blue)
- customer: Zákaznická (green)

Custom kinds will be merged with the default choices.

## Geographic Path Data

- **Detailed geometry serializers** for map views
- **GeoJSON export** endpoints
- **Path bounds and coordinates** in API responses

### GraphQL Support

## Development

### Setting Up Development Environment

1. Clone the repository:
```bash
git clone https://github.com/CESNET/cesnet_service_path_plugin.git
cd cesnet_service_path_plugin
```

2. Create a virtual environment:
```bash
python -m venv venv
source venv/bin/activate  # Linux/Mac
# or
.\venv\Scripts\activate  # Windows
```

3. Install development dependencies:
```bash
pip install -e ".[dev]"
```

4. Install geographic dependencies:
```bash
# Ubuntu/Debian
sudo apt-get install gdal-bin libgdal-dev libgeos-dev libproj-dev

# macOS
brew install gdal geos proj

# Install Python packages
pip install geopandas fiona shapely
```

### Testing Geographic Features

Use the built-in diagnostic function:
```python
from cesnet_service_path_plugin.utils import check_gis_environment
check_gis_environment()
```

## Navigation and UI

The plugin adds a **Service Paths** menu with:
- **Segments** - List and manage network segments
- **Segments Map** - Interactive map view of all segments
- **Service Paths** - Manage service path definitions
- **Mappings** - Relationship management tools

### Template Extensions

Automatic integration with existing NetBox models:
- **Circuit pages**: Show related segments
- **Provider pages**: List provider segments
- **Site/Location pages**: Display connected segments
- **Tenant pages**: Show associated provider information

## Troubleshooting

### Common Issues

1. **PostGIS not enabled**: Ensure PostGIS extension is installed in your database
2. **GDAL library missing**: Install system GDAL libraries before Python packages
3. **Path upload fails**: Check file format and ensure it contains LineString geometries
4. **Map not loading**: Verify JavaScript console for tile layer errors

### Debug Mode

Enable detailed logging for geographic operations:
```python
LOGGING = {
    'loggers': {
        'cesnet_service_path_plugin.utils': {
            'level': 'DEBUG',
            'handlers': ['console'],
        },
    },
}
```
