Unable to delete a device

[IsaacFL]

Trying to delete a device and get an error. I had the topology plugin at one time installed but removed and maybe related to that?

Hi @IsaacFL,

Sorry you're running into this. The error suggests that a database table from NetBox Topology Views was left behind when the plugin was removed and still references the device.

Please back up your database first, then follow the plugin removal guide, particularly the steps for removing the plugin's database tables and migration records. Also check the plugin's documentation for any plugin-specific removal steps.

Another possible approach is to reinstall and temporarily re-enable the same plugin version, then try reversing its migrations:

/opt/netbox/venv/bin/python3 /opt/netbox/netbox/manage.py migrate netbox_topology_views zero

I haven't tested this approach, and it might not work if the plugin version is incompatible with your current NetBox release, so please proceed with caution.
