Permission constraints key object

[Aof]

Hi all,

I'm still new to Netbox, so pardon my lack of information.

I just tried Netbox v.2.9.1 to try on the new permissions feature. Still struck on how to properly design permission constraints.

My question is how do I find the dict key of each field? e.g. If I were to add custom fields 'Team owner' on dcim > devices section, what json key I have to specify?

Right now, I only tried with tenant__group__name and it worked well. But how will I know what key value I have to put if I were to use another field?

Regards,

As I understand it, these constraints are Django query filters.

Custom fields are odd beasts in Netbox.  If you are working via the ORM you can access them (read-only) as cf_fieldname properties, but I'm pretty sure that won't work here.  At the database query level you have to do a nasty join onto customfieldvalue / customfieldchoice / customfield.

There is a proposal to overhaul custom fields by representing them as a JSON column, which should fix this:

Hi Brian,

Thanks for information.

Is there a instruction for me to query them? Either from GUI or from the OS. I'm just a simple user who don't have much knowledge about django and coding.

The built-in REST API documentation is a good place to start. It's not 100% consistent with the ORM (intentionally), but it should help you determine how to craft constraints for common use cases.

Hello,

Thanks again.  Seems like I can guess from the name and data from the api following https://netbox.readthedocs.io/en/stable/rest-api/filtering/ .

Still, can I query with some commands on NetBox Python Shell? https://netbox.readthedocs.io/en/stable/administration/netbox-shell/ this docs only contains existing objects. I'd like to find how to get query filter keys.

Thanks again for your help.
