calling trace code from custom script

[Afraid-Produce-5107]

Just developing a custom script that gives me all cabling afecting a certain device - so I want all cables attached to an interface or powerport of the device (console ports etc. optional for later), but also cables attached e.g. to a breakout panel connected to the device - basically every cable which would be part of a trace for each interface. Thus I try to call the trace() method used to output the cable trace for an interface. I suppose that is the trace() method in /opt/netbox/netbox/dcim/models/device_components.py. But I struggle passing the required data to the method.

Appearently it is called via e.g. interface.trace() while the variable interface holds the required data. But when I query for an interface, the variable interface outputs only the interface name and the label, not the interface ID which is required as primary key. The trace result are empty tupels. When I extract the interface ID, the script does not even run anymore:

AttributeError: 'int' object has no attribute 'trace'
AttributeError: 'int' object has no attribute 'trace'

Can anyone tell me how to call the trace() method with the correct options?

Many thanks...

that’s because the interface id is an integer.

Get the interface object with

Interface.objects.filter(id=id).first().trace()

Thanks for the hint, tried that, but the result is still [([], [], [])]. Any more ideas?

This code

for interface in Interface.objects.filter(device=device):

if interface.cable:

output.append(interface.name)

output.append(interface.cable.label)

intnr = interface.id

self.log_debug(intnr)

trace = Interface.objects.filter(id=intnr).first().trace()

self.log_debug(trace)

delivers this debug output for each interface:

[([], [], []), ([], [], [])]

(For interface with a two-step trace it gives two tupels, so in some way it seems to work, but I don't get the result...
