Removal of an option in a CustomFieldChoice does not update objects with the choiceset and the option selected

[cruse1977]

Deployment Type

NetBox Cloud

NetBox Version

v4.1.1

Python Version

3.12

Steps to Reproduce

• Create a CustomFieldChoices with some options (A,B,C)

• Create a Device Z
• Create a custom field of type selection with the CustomFieldChoices
• Assign the custom field to Device
• On Device Z, on the custom field, assign choice B

• In the CustomFieldChoiceSet delete option B

• View Device Z

Expected Behavior

The selected option on the choiceset attached to device Z should be null/none, due to the option removal

Observed Behavior

Option B remains until the object is edited or saved, despite no longer existing.

Note - Due to the options inherent within ChoiceSets (eg: Non Null, default etc) but I'm trying to ascertain if this is a bug (ie: NetBox should warn/error on Objects with this choice selected) or expected behaviour - hence requesting feedback

This should throw a validation error if you try to delete a choice and there are items assigned to that choice.

just my 0.02 cents, I prefer the exiting method. You should be able to remove options from a choice set, and objects currently referencing that option should maintain their selection until the next time you attempt to edit that object.

Removing a choice set doesn't make the choices selection on each object automatically invalid. It just means it's no longer available as a selection.
