Reverse binding to custom object

[joshsol1]

Plugin Version

0.4.0

Proposed functionality

NetBox Version
4.4.4

Python Version
3.12

Current Behavior:
Create a custom object type X with fields Name (as type text), devices, sites and vlans (as type multiple object)
Add custom object of "Name: Y" to custom object type X, add required devices and vlans shows up great.
Add custom field to DCIM > Devices as type "single object" pointing to custom object Y.
Add custom field to DCIM > Site as type "single object" pointing to custom object Y.
Add custom field to IPAM > VLANs as type "single object" pointing to custom object Y.
Create a new Device, Site or VLAN and select custom object Y under the custom field.
This shows Y under the custom field as a link to the custom object but does not add the new Device/Site/VLAN in the custom object meaning mapping new objects is a two-step process.

Example Desired Behavior:
Create a custom object type X with fields Name (as type text), devices, sites and vlans (as type multiple object)
Add custom object of "Name: Y" to custom object type X.
Add custom field to DCIM > Devices as type "single object" pointing to custom object Y > Devices.
Add custom field to DCIM > Site as type "single object" pointing to custom object Y > Sites.
Add custom field to IPAM > VLANs as type "single object" pointing to custom object Y > VLANs.
Create a Device, Site or VLAN and select custom object Y under the custom field.
The Device/Site/VLAN appears under the mapped field in the custom object.

Use case

This would remove the need to double handle data when adding new devices meaning links and references could be added in both directions avoiding user error in mapping attributes to custom objects.

@joshsol1 can you please do a quick mockup of what you are asking for here? It is not really clear what you are specifically asking for from the description.

Yeah sure, what I meant was to be able to create a custom object type similar to this (using devices, vlans and sites as the example)

Add a series of entries to the custom object with the name filled in.

You can add devices, vlans and sites to the custom object.

They appear as expected.

The additional feature request is to be able to then map the devices, sites and vlans fields to a custom field.

On a device for instance, in the new custom field select which entry in the custom object the device should be linked to.

Which then appears on the device.

And also have the device appear on the custom object here.

@joshsol1 we still are having difficulty understanding exactly what you are getting at, can you please look at re-writing the FR description to make it more clear and what the use case is? It seems like you are wanting something like a custom object going to a custom field going to a device and having the custom object appearing on that device? Is there anything in NetBox that currently works similar to what you want that you can point to?
