setting manual IP address fails

hush-dingy · May 3, 2025, 5:32pm

Brief description of the problem

Went to change from DHCP to manual and got the following error. Oddly enough if I go back in to do the same steps then the original DHCP IP address is in the IP field followed by the IP address I tried to manually assign:

Thanks to user [franao68](https://forum.rockstor.com/u/franao68), reporting on a…n issue related to network adapter changes: https://forum.rockstor.com/t/help-error-config-network-ip-dhcp-rockstor-web-gui/10520. I was able to reproduce the issue on 5.0.15-0 - Create a new network connection against an existing adapter using docker network and dhcp, name "JustANewOne" - completed - enter existing connection (which is now based on the docker adapter - Switch from dhcp to manual - add valid docker IP address, dns, etc. <img width="745" alt="Image" src="https://github.com/user-attachments/assets/003a3ecc-16d6-4965-ab8d-b2d0965377bf" /> - select submit - Error message is thrown. Traceback: ``` Traceback (most recent call last): File "/opt/rockstor/src/rockstor/rest_framework_custom/generic_view.py", line 40, in _handle_exception yield File "/opt/rockstor/src/rockstor/storageadmin/views/network.py", line 449, in put device = nco.networkdevice_set.first().name ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ AttributeError: 'NoneType' object has no attribute 'name' ``` Interestingly enough it seems to retain the DNS server I entered, even when doing a hard re-load of the browser (using developer tools). <img width="470" alt="Image" src="https://github.com/user-attachments/assets/f4adab5e-1b36-4272-a04e-b0b0618978a5" /> While in here, when switching back to `dhcp` and trying to submit, error message is again/still being thrown But also, no member device is shown on the top-level: <img width="1087" alt="Image" src="https://github.com/user-attachments/assets/f7865319-41ff-4383-9dfa-b0b154733568" /> though a hard reload rectifies the situation. I am able to delete the connection. Using an existing "real" ethernet connection and switching it from dhcp to manual, updating appropriate fields: <img width="785" alt="Image" src="https://github.com/user-attachments/assets/cbf149e2-581f-4b2c-9060-7c102ebceab6" /> A different error is thrown: ``` Traceback (most recent call last): File "/opt/rockstor/src/rockstor/rest_framework_custom/generic_view.py", line 40, in _handle_exception yield File "/opt/rockstor/src/rockstor/storageadmin/views/network.py", line 534, in put return Response(NetworkConnectionSerializer(nco).data) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/opt/rockstor/.venv/lib/python3.11/site-packages/rest_framework/serializers.py", line 571, in data ret = super().data ^^^^^^^^^^^^ File "/opt/rockstor/.venv/lib/python3.11/site-packages/rest_framework/serializers.py", line 249, in data self._data = self.to_representation(self.instance) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/opt/rockstor/.venv/lib/python3.11/site-packages/rest_framework/serializers.py", line 525, in to_representation attribute = field.get_attribute(instance) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/opt/rockstor/.venv/lib/python3.11/site-packages/rest_framework/fields.py", line 437, in get_attribute return get_attribute(instance, self.source_attrs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/opt/rockstor/.venv/lib/python3.11/site-packages/rest_framework/fields.py", line 104, in get_attribute instance = getattr(instance, attr) ^^^^^^^^^^^^^^^^^^^^^^^ File "/opt/rockstor/src/rockstor/storageadmin/models/network_interface.py", line 81, in ctype if self.ethernetconnection_set.count() > 0: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/opt/rockstor/.venv/lib/python3.11/site-packages/django/db/models/manager.py", line 87, in manager_method return getattr(self.get_queryset(), name)(*args, **kwargs) ^^^^^^^^^^^^^^^^^^^ File "/opt/rockstor/.venv/lib/python3.11/site-packages/django/db/models/fields/related_descriptors.py", line 718, in get_queryset raise ValueError( ValueError: 'NetworkConnection' instance needs to have a primary key value before this relationship can be used. ``` And, then it becomes very strange. Another "hard" reload of the network page: <img width="1093" alt="Image" src="https://github.com/user-attachments/assets/cdbc2908-ed1b-4b73-b31d-797c6778529e" /> it now shows "docker type" IP info. When going into the connection (change mode), I am presented with this: <img width="766" alt="Image" src="https://github.com/user-attachments/assets/c4b6430e-45c8-4cb1-b393-21232f503f8e" /> Soooo, not entirely sure what's going on. In the devtools I saw an internal server error 500 that seems to be thrown by jquery, but I did not look into too much detail there.

which was based on this forum report:

As a workaround you could use the nmtui at the command line, where you can also edit connections as the above author did.
