Parent module position not propagated to nested module name

[JakubDokladal]

Deployment Type

Self-hosted

NetBox Version

v4.2.3

Python Version

3.12

Steps to Reproduce

1. Create a device type "storage array" with for example 2 module bays for "storage controllers" with positions like "A" and "B"
2. Create module type of "storage controller" with module bays for 4 SFP modules for which the name contains {module}
3. Instantiate the "storage array" device
4. Populate the "storage array" module bay with a "storage controller" module

Expected Behavior

The nested "SFP" module name would gets populated by "storage controller" module position e.g. A

Observed Behavior

The nested "SFP" module name gets populated by uninterpreted {module} string.

Hello @JakubDokladal could you add more details about how to repreduce the issue ?
And what table is that one you added the image?

Hello @renatoalmeidaoliveira
Updating with more details as you requested.

1. Create a Device type (Storage Array) with 2 module bays for Storage Array Controllers

Name	Label	Position
Controller A	Label Controller A	Position Controller A
Controller B	Label Controller B	Position Controller B

2. Create a Module type (Storage Array Controller) with 4 module bays for SFPs

Name	Label	Position
Controller {module} - Slot 1	Label Slot 1	Position Slot 1
Controller {module} - Slot 2	Label Slot 2	Position Slot 2
Controller {module} - Slot 3	Label Slot 3	Position Slot 3
Controller {module} - Slot 4	Label Slot 4	Position Slot 4

3. Create a Module type (Storage Array Controller SFP) with 1 interface

Name	Type
Parent [{module}] Child [{module}] - Port 1	SFP+ (10GE)

4. Create a Device instance of Device type created in point 1. (Storage Array)

5. Add a Storage Array Controller Module to the newly created Device Instance Module bay

I would expect that the {module} in the name of the child module bay (or actually ideally even in the child label and child position) would get populated from the parent position like it does for example for interfaces.
From the screenshot, that the Controller {module} - Slot 1 would actually be Controller Position Controller A - Slot 1

6. Add a Storage Array Controller SFP Module to the Storage Array Controller Module bay

For the interface name the positions get correctly populated even for the nested multi-module hierarchy

@renatoalmeidaoliveira can you please see if you can reproduce this issue as you are already working on the other one. I'll assign it to you.

[renatoalmeidaoliveira]

@arthanson tested and confirmed the issue in current release and post ##18643.
I think it can be closed as fixed by #18643

Thanks @renatoalmeidaoliveira. I'm going to close this out as a duplicate of #17436, which was fixed in NetBox v4.2.4.
