Ingesting Cable using diode-sdk-python

[SRF-oberlicy]

Diode SDK Python version

1.0.0

Diode version

1.0.0

Diode NetBox Plugin version

1.0.1

NetBox version

4.2.3

Steps to reproduce

• Netbox Diode installed
• Python Script successfully connecting to diode

Ingesting one or multpile cables in the following format:

cable = Cable(
            a_terminations=[GenericObject(
                object_interface=Interface(
                    name="Interface A",
                    type="virtual",
                    device="Device ABC"
                ))],
            b_terminations=[GenericObject(
                object_interface=Interface(
                    name="Interface B",
                    type="virtual",
                    device="Device ABC"
                ))]
        )

Expected behavior

I expect the cable to be created in netbox just as it works in a similar matter with devices, ip addresses or interfaces.

Observed behavior

Instead, I get an error from diode:
Exception Type: TypeError at /api/plugins/diode/generate-diff/ Exception Value: unhashable type: 'dict' Raised during: netbox_diode_plugin.api.views.GenerateDiffView

I believe I'm also experiencing this issue - both with GenericObject() cable_terminations and interfaces.

Unsure if the OP was experiencing this as an error from the diode / python sdk itself or from the actual netbox instance, my error is from the former.

From the netbox logs:

Hey @BagMan9,

I think it's not actually a bug that it doesn't work, it just seems to be not implemented yet. It is not in the supported objects list here: supported objects

I solved it with pynetbox which works straightforward for cable ingestion:

connection = {
  "termination_a": {
    "interface_name": switch_interface_name,
    "device_name": switch_name,
  },
  "termination_b": {
    "interface_name": device_interface_name,
    "device_name": device_name,
  }
}
