Sure - but the issue was triggered by ignorance:

Python version: 3.6.9
NetBox version: 2.6.6

from dcim.models import Device
from extras.models import CustomFieldValue

My first test...

for device in Device.objects.all():
    test = CustomFieldValue.objects.filter(obj_id=device.id)
    if test:
        self.log_info(
            device,
            "custom_fields on {} : {}".format(device.name, test)
        )

...any results - but What the right way to filter for a boolean CustomField my_field?
