Struggling with Netbox permission to restrict specific device role view

[BartBaljon]

Hello team,

I am working on a few permissions for our helpdesk team and I would like to exclude their abilities to see devices that have device roles, such as "Core" or "Firewall".

Trying to figure this out, I resorted to ChatGPT for support and it provided me the following JSON constraint but it doesn't appear to be working for me.

{
  "role__slug__nin": ["coreswitch"]
}

Whenever I apply this constraint to DCIM > Device, it shows the following error:

Invalid filter for <class 'dcim.models.devices.Device'>: Unsupported lookup 'nin' for SlugField or join on the field not permitted, perhaps you meant in?

If I try this same constraint but use it on object DCIM > Device Role, it spits out the following:

Invalid filter for <class 'dcim.models.devices.DeviceRole'>: Cannot resolve keyword 'role' into field. Choices are: bookmarks, color, config_template, config_template_id, created, custom_field_data, description, devices, id, journal_entries, last_updated, name, slug, subscriptions, tagged_items, tags, virtual_machines, vm_role

I can't seem to find a solution online on how to exclude certain permissions from seeing specific criteria as I don't want helpdesk or other to be able to see specific critical infrastructure.

Does anybody know what I am doing wrong here?

I am currently using Netbox v4.1.6
