User: pynetbox usage
Assistant: **pynetbox** is a Python library designed to interact with the NetBox API. NetBox is an infrastructure resource modeling (IRM) tool used for managing and documenting computer networks.

With **pynetbox**, you can automate tasks such as querying devices, managing IP addresses, creating and updating data in NetBox via its REST API, all using Python.

---

### Installation

You can install pynetbox via pip:

```bash
pip install pynetbox
```

---

### Basic Usage

Here's a basic example to get you started with **pynetbox**:

```python
import pynetbox

# Connect to the NetBox instance
nb = pynetbox.api(
    'http://netbox.example.com',  # URL of NetBox
    token='your_api_token_here'   # Your API Token for authentication
)

# Example: List all devices
devices = nb.dcim.devices.all()
for device in devices:
    print(f"Device Name: {device.name} - Device Role: {device.device_role.name}")
```

---

### Common Tasks

#### 1. Retrieve all devices

```python
devices = nb.dcim.devices.all()
for device in devices:
    print(device.name)
```

#### 2. Get a device by name

```python
device = nb.dcim.devices.get(name='your-device-name')
print(device.serial)
```

#### 3. Create a new device

```python
new_device = nb.dcim.devices.create(
    name='switch01',
    device_role=1,       # Usually you need to supply the ID of existing objects
    device_type=2,
    site=1,
    status='active'
)
print(new_device)
```

> Note: For creating or updating objects, you often have to supply existing related object IDs.

#### 4. Update a device

```python
device = nb.dcim.devices.get(name='switch01')
device.update({'status': 'decommissioned'})
```

#### 5. Get IP addresses

```python
ips = nb.ipam.ip_addresses.all()
for ip in ips:
    print(ip.address)
```

### Additional Notes

- **API Token**: You can generate an API token in NetBox under your user profile.
- **Models**: `pynetbox` provides access to all NetBox models grouped by apps, e.g.:
  - `nb.dcim` (Devices, Racks, Sites)
  - `nb.ipam` (IP Addresses, Prefixes)
  - `nb.virtualization` (Virtual Machines)
  - etc.

- You can create, update, delete, and retrieve objects as long as your API token permissions allow these operations.

---

### Example: Search for devices with a role of "Router"

```python
roles = nb.dcim.device_roles.filter(name='Router')
if roles:
    role_id = roles[0].id
    routers = nb.dcim.devices.filter(device_role=role_id)
    for r in routers:
        print(r.name)
else:
    print("No device role named 'Router' found")
```

User: how to get rendered config-context for device
Assistant: To get the **rendered config context** for a device via the NetBox API using `pynetbox`, you need to interact with the **config context** endpoints.

NetBox’s Config Context feature allows you to attach arbitrary JSON data to objects (like devices), and the API has a "rendered" view that merges all applicable config contexts for the device.

---

### How to get rendered config context for a device using `pynetbox`

1. You need the device's ID or name to identify it.
2. Use the `/dcim/devices/:id/config-context/` endpoint, which returns the merged/rendered config context for the device.

`pynetbox` exposes this endpoint as a method of the `device` object.

---

### Example code snippet

```python
import pynetbox

# Connect to NetBox API
nb = pynetbox.api(
    'http://netbox.example.com',  # Replace with your NetBox URL
    token='your_api_token_here'   # Replace with your API token
)

# Get the device by name or ID
device = nb.dcim.devices.get(name='your-device-name')  # or .get(id=123)

if device:
    # Get the rendered config context for the device
    config_context = device.config_context()

    # config_context is a dict representing the merged config context JSON for the device
    print(config_context)
else:
    print("Device not found.")
```

---

### Notes:

- `device.config_context()` calls the `/dcim/devices/:id/config-context/` endpoint under the hood.
- The returned data is a Python dictionary representing the merged config context JSON data for that device.
