NetBox version

v3.3.0

Python version

3.9

Steps to Reproduce

  1. upgraded netbox to v3.3.0
  2. click at an affected pdu (device)

Expected Behavior

I expect that the pdu device is displayed.

Observed Behavior

An error page with "TypeError" is thrown. Not every pdu is affected although of same device type.

If deleting the cable of an affected pdu to the power feed, the pdu device is opened correctly. If I create the cable again, the type error page is present instead of the device page.
With option "DEBUG = True" in configuration.py the type error page displays some helpful information (attached at bottom). I think there is something wrong at the power utilization graph because of type mismatch.

Template error:

  1. upgraded netbox to v3.3.0
  2. click at an affected pdu (device)

I'm afraid that's not going to be sufficient to reproduce the reported behavior. Please try to determine steps that someone else can follow to reliably reproduce the issue.

Exception Type: TypeError at /dcim/devices/79/
Exception Value: unsupported operand type(s) for /: 'str' and 'int'

This indicates that powerfeed.available_power is being passed as a string. I'm not sure how that could happen, as available_power is a required PositiveIntegerField and can never be anything other than an integer.

Ok, I suspected that. I will see what I can do. I may need some time to figure out how to reproduce this.

I'm curious what the value of that field is for the affected power feed. Can you inspect it using the shell? (Grab the numeric ID of the feed first; in the example below it's 19.)

$ ./manage.py nbshell
### NetBox interactive shell (jstretch-workstation)
### Python 3.8.13 | Django 4.0.7 | NetBox 3.3.2-dev
### lsmodels() will show available models. Use help(<model>) for more info.
>>> PowerFeed.objects.get(pk=19)
<PowerFeed: P1-10A>
>>> PowerFeed.objects.get(pk=19).available_power
3520

I've checked the PowerFeed but it seems that it is not a string:

./manage.py nbshell
### NetBox interactive shell (netbox-beta)
### Python 3.9.2 | Django 4.0.7 | NetBox 3.3.0
### lsmodels() will show available models. Use help(<model>) for more info.
>>> PowerFeed.objects.get(pk=49)
<PowerFeed: Feld01 - F04>
>>> PowerFeed.objects.get(pk=49).available_power
11085

So I've tried something other and played around with value "allocated draw" of the pdu's power port.
If opening page "Power Ports" of an affected pdu direct via url "/dcim/devices/[dev-id]/power-ports/" it seems that the power port has no allocated draw (displayed with a line). But if I edit this power port, adding for example 5 watts as allocated draw, the affected pdu is accessible without a type error page and device page is displayed like it should (except of this fictional allocated draw value).
I checked the nbshell in both cases:

  • case with non set allocated draw:
### NetBox interactive shell (netbox-beta)
### Python 3.9.2 | Django 4.0.7 | NetBox 3.3.0
### lsmodels() will show available models. Use help(<model>) for more info.
>>> d = Device.objects.get(pk=48)
>>> 
>>> p=d.powerports.get()
>>> p.get_power_draw()
{'allocated': 0, 'maximum': 5097, 'outlet_count': 24, 'legs': [{'name': 'A', 'allocated': 0, 'maximum': 1695, 'outlet_count': 8}, {'name': 'B', 'allocated': 0, 'maximum': 2002, 'outlet_count': 8}, {'name': 'C', 'allocated': 0, 'maximum': 1400, 'outlet_count': 8}]}
  • case with manually set allocated draw to 120W:
### NetBox interactive shell (netbox-beta)
### Python 3.9.2 | Django 4.0.7 | NetBox 3.3.0
### lsmodels() will show available models. Use help(<model>) for more info.
>>> d = Device.objects.get(pk=48)
>>> p=d.powerports.get()
>>> p.get_power_draw()
{'allocated': 120, 'maximum': 0, 'outlet_count': 24, 'legs': []}

In both cases I can not recognize any string values. I hope this information is helpful somehow.

@jaylik Thank's for your monkey patch. I tried your device.html template patch. Now affected PDUs displayed properly without error page (I didn't check it with all affected PDUs, but checked two of them).

What I also tried without patching something: If I connect the power port of an PDU with a three-phase power feed, problem appears. Now if edit the power feed and switch to a single-phase type, the PDU is displayed without error page. As @jaylik already said, it seems that this problem appears at three-phase power feeds. What I can say, we mainly use three-phase feeds but I don't have this bug with all of our three-phase feeded PDUs.
Another try without patching something: if connecting the power port of affected PDU with two power feeds (possible since v3.3.0 because of the new cable model) the PDU is displayed properly. Both feeds are three-phase types.
Because this bug comes with upgrade to v3.3.0 I think it has something to do with the new cable model.

Another try without patching something: if connecting the power port of affected PDU with two power feeds (possible since v3.3.0 because of the new cable model) the PDU is displayed properly. Both feeds are three-phase types. Because this bug comes with upgrade to v3.3.0 I think it has something to do with the new cable model.

What I can say, we mainly use three-phase feeds but I don't have this bug with all of our three-phase feeded PDUs.

I missed the fact, that our non-affected PDUs have a manually set allocated draw. If deleting the allocated draw of PDU power port, the exception page is present.

@baschdello do you have a repro scenario for this? I tried using three-phase power feed and wasn't able to get it to repro. A step-by-step repro would be greatly appreciated.

I will try this on monday with a fresh installation of v3.3.0 and give feedback.

I've reproduced this issue with a fresh installation of v3.3.0. Here are steps to reproduce:

  1. create site "dc1"
  2. create power-panel "usv-a"
  3. create rack "rack1" and assign it to site "dc1"
  4. create power-feed "feed1" with following details:
    Power Panel "usv-a"
    Rack "rack1"
    Phase "three-phase"
  5. create manufacturer "manufacturer1"
  6. create device-type "pdu" with manufacturer "manufacturer1"
  7. add power-port "Power" to device-type "pdu" with plug type "3P+N+E 6H"
  8. add power-outlets (one for each leg) "out1", "out2" and "out 3" with options:
    type "C13"
    power port "Power"
    feed leg "out1" => leg A, "out2" => leg B, "out 3" => leg C
  9. create devicerole "pdu"
  10. at our "rack1" create a pdu as non-racked device with the devicerole "pdu" and choose device-type "pdu"
  11. connect pdu power-port to power-feed and choose:
    Power Panel "USV-A"
    Power Feed "feed1"
  12. open the created device "pdu" and you will see the TypeError-page.

Best regards

I don't think #10961 fully fixed the issue.

Here powerfeed is set using the removed connected_endpoint: https://github.com/netbox-community/netbox/pull/10961/files#diff-244731798e872e98b04c335c35679f920c3e5c90e8bf2340471f7910bd0449cdL232
Which means it will always be None.

I think the proper fix would be to change it to use connected_endpoints (plural).

There are also two other locations where connected_endpoint is still referenced:

b1da374df2/netbox/templates/dcim/interface.html (L213)

b1da374df2/netbox/templates/dcim/rack.html (L176)
