Environment

  • Python version: 3.7.9
  • NetBox version: 2.9.2
  • Docker Image: netboxcommunity/netbox:2.9.2-ldap

Steps to Reproduce

  1. Setup Netbox 2.8.9
  2. Fill in IP Addresses
  3. Set the table to display the "Parent" column or create a user setting like this:
tables.IPAddressDetailTable.columns: ['address', 'vrf', 'status', 'role', 'tenant', 'assigned', 'dns_name', 'description', 'parent']
  1. Upgrade to 2.9.x
  2. The parent column no longer exists, Netbox produces an error and does not indicate this is related to a bad user setting

Expected Behavior

A list of IP Addresses is shown, Netbox either warns the user that their table configuration is now invalid or clears the invalid column from the user settings.

Observed Behavior

Netbox shows an error page:

There was a problem with your request. Please contact an administrator.

The complete exception is provided below:

<class 'KeyError'>

'parent'

Python version: 3.7.9
NetBox version: 2.9.2

Workaround: Navigate user profile > preferences and delete the column ordering for the affected table.
