Cable trace in cable view

[CaptainBalou]

NetBox version

v3.4.3

Feature type

Change to existing functionality

Proposed functionality

It would be awesome to have the possibility to click on tracing a cable while viewing the cable (e.g. https://localhost/dcim/cables/1/)

as well as on the list view

Use case

Being in the data center, seeing a cable without knowing whats connected would involve searching for the cable ID printed on the cable label. After finding it in Netbox it would be nice to see a trace icon in the list overview as well as in the details page of each cable to be able to directly get a trace to each end without the need of click of one connected interface to click on trace there (see example screenshots above in the proposal).

I'll note that cable traces need to start from a specific termination point (rather than from the cable itself) to imbue a direction of the trace, but we can add trace buttons to the termination objects.

I was looking into this.. The only place that I can add the trace, is on the Cable page, on the interface (if shown).

As a cable can have multiple interfaces on each termination side, it is not possible to create a 'trace' button for the 'cable' or show it in the cable list.
Unless we assume that is the a_terminations[0] or b_terminations[0] exists, that we can start the trace from there..

[PieterL75]

2 options for the 'list' view :

either a button next to the termination or a dropdown with all possible traces of that cable.
The first one is easy, then I can decide in the python code of the interface is a 'interface/front/rear', other types are not traceable. The dropdown is more difficult (I think) as it there is no type of the termination/cable passed to the django template

[PieterL75]

I think I have something that works. See PR..
If we start the trace of any termination of that cable, we get the trace. You won't be able to trace from A-Z or Z-A, just the first valid iface is picked.
In the end, the result is that the cable is shown.

Hello,

I really appreciate that you guys are thinking about this directly. Thanks. @PieterL75 is even faster in changing the code then I had the time to look at the proposals. Awesome. :-)
Because the list is not very crowded I would prefer the icon directly in the list. But a drop-down would also be good. Both makes it easier for users to reach the trace with fewer clicks.

Kind regards
Marco
