Deleting vlan deployed on interface causes Server Error

See original GitHub issue

Environment

Python version: 3.8.7
NetBox version: 2.10.4

Steps to Reproduce

Create a VLAN (specify VID and VLAN name, no specific configuration needed)
Use this vlan as access on a interface: select an interface in a device, configure 802.1q mode (say access), select previously created vlan in “Untagged VLAN”. Please note it also works when using the tagged option.
Delete the previously created VLAN (select VLAN, delete, confirm).
Go back to the page of the interface => the Server Error occurs.

Expected Behavior

Option A: prevent VLAN from being delete as configuration of interface depends on it. Option B: delete the vlan from the configuration of the interface when the vlan is deleted from NetBox.

Observed Behavior

Following error occurs when browsing the interface:

<class 'ipam.models.VLAN.DoesNotExist'>

VLAN matching query does not exist.

Python version: 3.8.7
NetBox version: 2.10.4

I would favor option B, as from a user standpoint, deleting a vlan should remove this vlan on all interfaces. However, dealing with access interfaces could be more tricky…

I updated my original post above. I really didn’t do anything specific to trigger this behaviour. Please let me know if I need to provide any additionnal information or steps.

Closing this out as caching is being removed in v3.0. The workaround for now is to disable caching by setting CACHE_TIMEOUT = 0 in configuration.py.
