Dynamic use of user input in netbox script before def run starts

[ctsalidis]

Hi Community,

Is it possible in a netbox script to get a device input from the user and list all interfaces of the device in a drop down menu so that the user chooses an interface before the def run is executed?

This way, we could dynamically use the user input to collect another input related to the first one before execution.

Thank you!

You can reference the device variable via 'device_id' in your query_params of the Interface model to accomplish this. After selecting a device (or multiple), the Interface dropdown would then populate with only related interfaces.

Hi @zmaster7,

Thank you for your input!

The following lines return an error! ObjectVar object has no id.

class TestSCRIPT(Script):
class Meta:
name = "xxx"
description = "xxx"

    scheduling_enabled = False

device = ObjectVar(model=Device, label="Device", description="Select the device", required=True)
interface = ObjectVar(model=Interface, label="Interface", description="Select the interface of the above device", required=True, query_params={"device_id": device.id})


def run(self, data, commit):
    selected_device = data['device']
    self.log_info(f"Device ID: {selected_device.id}")

I guess this dynamic approach to use the device input for filtering the options of the next objectvar (interface) is not possible or?

Thank you!

If you change device.id to $device under query_params then it should work for you:

query_params={"device_id": $device}

You can see similar examples from the custom scripts documentation .

Hi @zmaster7,

Thank you. It works! I thought the dynamic approach couldn't work.
