macwatch AttributeError when attempting to post events under NAV 4.3.0

[Morten Brekkevold]

Under NAV 4.3.0, when the macwatch cron job tries to post an event about a watched mac, it crashes with a Python AttributeError, which is mailed back to the admin through crond.

It appears the problem is that the event posting code tries to extract a deviceid from a Netbox, which is no longer possible under the new db schema in NAV 4.3.

Traceback example:

Traceback (most recent call last):
  File "/usr/lib/nav/macwatch.py", line 263, in <module>
    main()
  File "/usr/lib/nav/macwatch.py", line 247, in main
    if post_event(mac_watch, cam, logger):
  File "/usr/lib/nav/macwatch.py", line 103, in post_event
    deviceid=cam.netbox.device_id,
AttributeError: 'Netbox' object has no attribute 'device_id'
