Cable Trace Question

[theredon]

Is there a way to add a custom field to display in the cable trace?

We use a taping system to identify tower cables and I've built a custom field to add it to the cables, but would like it to show up here as well if possible. I haven't been able to find any way to do it, so I'm guessing my best bet would be to create a report to export the details to a CSV instead of being about to download the SVG with the information on it, but figured I'd ask just in case.

No, it's not templated. For example, in order to get circuit descriptions added I needed to raise a feature request: #12831

Here's the code which labels a cable, in netbox/dcim/svg/cables.py:

        # If the cable count is higher than 2, collapse the description into a tooltip
        if cable_count > 2:
            ... snip
        else:
            labels = [
                f'Cable {cable}',
                cable.get_status_display()
            ]
            description = []
            if cable.type:
                labels.append(cable.get_type_display())
            if cable.length is not None and cable.length_unit:
                # Include the cable length in the tooltip
                labels.append(f'{cable.length} {cable.get_length_unit_display()}')

and in turn, {cable} invokes Cable.__str__ from netbox/dcim/models/cables.py

    def __str__(self):
        pk = self.pk or self._pk
        return self.label or f'#{pk}'

In the absence of a hook to format the SVG labels, and without wanting to maintain your own fork of Netbox, you're probably best duplicating the logic in a plugin (or as you say, export and then render externally)
