Environment

  • Python version: 3.6.8
  • NetBox version: 2.10.3

Steps to Reproduce

(GUI and API via Ansible module)

  1. Create VM with 1 NIC
  2. Create a IPv4 Address
  3. Assign IPv4 address to NIC
  4. Set IPv4 to primary IP on VM
- name: set primary IP4
     netbox.netbox.netbox_virtual_machine:
        netbox_url: "{{url}}"
        netbox_token: "{{token}}"
        validate_certs: no
   data:
     name: "{{server_name}}"
     primary_ip4: "{{IP}}"

Expected Behavior

IPv4 to be set as primary IP

Observed Behavior

1 out of every 5 or so request will error out. We have noticed other calls failing with the same error but this action is the most common that we have seen fail. This if after we upgraded to 2.10.3
Error:

<class 'ValueError'>

Cannot assign "<SimpleLazyObject: <django.contrib.auth.models.AnonymousUser object at 0x7f0ea5454da0>>": "ObjectChange.user" must be a "User" instance.

Python version: 3.6.8
NetBox version: 2.10.3

Related isssue: https://github.com/netbox-community/netbox/issues/5142
The problem has not been resolved and appears itself when bulk objects are changed (no matter via API or WebUI) while other users are working in Netbox.

@jeremystretch after some troubleshooting we found out that the cause of this error was having threading enabled in our uWSGI configuration.

If we set the thread count to anything above 1 we would see the error. Increasing the process count > 1 does not cause the error.

Hi, everyone! I'm experiencing the same behavior after updating to the 2.10.6.

I making PATCH "virtualization_virtual-machines_partial_update" requests via aionetbox just updating the statuses of various VMs.
The statuses are actually being updated, but I'm getting these strange exceptions and 5XX.

Setting threads=1 in gunicorn.py also fixed this issue for me

@Dimaqa does this solution have any impact on performance ??

@gmurman770 commented on GitHub (Apr 1, 2021): Hi, everyone! I'm experiencing the same behavior after updating to the 2.10.6. I making PATCH "virtualization_virtual-machines_partial_update" requests via aionetbox just updating the statuses of various VMs. The statuses are actually being updated, but I'm getting these strange exceptions and 5XX. /opt/netbox/logs/netbox.log: ```Internal Server Error: /api/virtualization/virtual-machines/226/ Traceback (most recent call last): File "/opt/netbox/venv/lib64/python3.6/site-packages/django/core/handlers/exception.py", line 47, in inner response = get_response(request) File "/opt/netbox/venv/lib64/python3.6/site-packages/django/core/handlers/base.py", line 181, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/opt/netbox/venv/lib64/python3.6/site-packages/django/views/decorators/csrf.py", line 54, in wrapped_view return view_func(*args, **kwargs) File "/opt/netbox/venv/lib64/python3.6/site-packages/rest_framework/viewsets.py", line 125, in view return self.dispatch(request, *args, **kwargs) File "/opt/netbox/netbox/netbox/api/views.py", line 184, in dispatch return super().dispatch(request, *args, **kwargs) File "/opt/netbox/venv/lib64/python3.6/site-packages/rest_framework/views.py", line 509, in dispatch response = self.handle_exception(exc) File "/opt/netbox/venv/lib64/python3.6/site-packages/rest_framework/views.py", line 469, in handle_exception self.raise_uncaught_exception(exc) File "/opt/netbox/venv/lib64/python3.6/site-packages/rest_framework/views.py", line 480, in raise_uncaught_exception raise exc File "/opt/netbox/venv/lib64/python3.6/site-packages/rest_framework/views.py", line 506, in dispatch response = handler(request, *args, **kwargs) File "/opt/netbox/venv/lib64/python3.6/site-packages/rest_framework/mixins.py", line 82, in partial_update return self.update(request, *args, **kwargs) File "/opt/netbox/venv/lib64/python3.6/site-packages/rest_framework/mixins.py", line 68, in update self.perform_update(serializer) File "/opt/netbox/netbox/netbox/api/views.py", line 232, in perform_update instance = serializer.save() File "/opt/netbox/venv/lib64/python3.6/site-packages/rest_framework/serializers.py", line 200, in save self.instance = self.update(self.instance, validated_data) File "/opt/netbox/netbox/extras/api/serializers.py", line 93, in update instance = super().update(instance, validated_data) File "/opt/netbox/venv/lib64/python3.6/site-packages/rest_framework/serializers.py", line 983, in update instance.save() File "/opt/netbox/venv/lib64/python3.6/site-packages/django/db/models/base.py", line 754, in save force_update=force_update, update_fields=update_fields) File "/opt/netbox/venv/lib64/python3.6/site-packages/django/db/models/base.py", line 803, in save_base update_fields=update_fields, raw=raw, using=using, File "/opt/netbox/venv/lib64/python3.6/site-packages/django/dispatch/dispatcher.py", line 179, in send for receiver in self._live_receivers(sender) File "/opt/netbox/venv/lib64/python3.6/site-packages/django/dispatch/dispatcher.py", line 179, in <listcomp> for receiver in self._live_receivers(sender) File "/opt/netbox/netbox/utilities/utils.py", line 283, in _curried return _curried_func(*args, *moreargs, **{**kwargs, **morekwargs}) File "/opt/netbox/netbox/extras/signals.py", line 39, in _handle_changed_object objectchange.user = request.user File "/opt/netbox/venv/lib64/python3.6/site-packages/django/db/models/fields/related_descriptors.py", line 220, in __set__ self.field.remote_field.model._meta.object_name, ValueError: Cannot assign "<SimpleLazyObject: <django.contrib.auth.models.AnonymousUser object at 0x7fdfdd373128>>": "ObjectChange.user" must be a "User" instance. ``` > Setting threads=1 in gunicorn.py also fixed this issue for me @Dimaqa does this solution have any impact on performance ??

@gmurman770 I've ran some tests suggested in https://github.com/netbox-community/netbox/issues/5142#issuecomment-726363506 and for some reason they showed even better time results
