Issues with showing child prefixes

[trrunde]

NetBox version

v3.0

Python version

3.8

Steps to Reproduce

In version 2.x I had added some more column to be visible on the prefixes. I believe it was "Tags"
after upgrading to version 3.0 I get the following error when clicking "child prefixes" on a prefix.

The complete exception is provided below:

<class 'AttributeError'>

'str' object has no attribute 'available_columns'

Python version: 3.8.6
NetBox version: 3.0.0

Expected Behavior

Page showing child prefixes

Observed Behavior

The complete exception is provided below:

<class 'AttributeError'>

'str' object has no attribute 'available_columns'

Python version: 3.8.6
NetBox version: 3.0.0

Have you tried clearing out your table preferences (under your user profile)? Are you able to recreate this on v3.0.0 alone?

[rodvand]

I am able to reproduce on my test instance, as well as the NetBox Beta Demo instance (https://beta-demo.netbox.dev/ipam/prefixes/1/) and click Child Prefixes. And I can't see any user preferences on my profile that should result in this (nothing related to prefix).

@rodvand can you please share the specific steps you're taking to reproduce the bug on v3.0.0?

have not tested that, will check settings to clear my profile then adding the column back after.

Tried clearing the columns on my profile page, same result. Got some more details about the traceback error in the email sent from netbox.

I am able to reproduce on my test instance

@rodvand can you please share the specific steps you're taking to reproduce the bug on v3.0.0?

Its enough to open a prefix, then click "child prefixes" This will lead to an error with 'str' object has no attribute 'available_columns'

[fkusei]

Can confirm the same issue. Was upgrading from 2.11.11 to 3.0.0, cleared user preferences after upgrading. Same error, same log entry.

Can provide a copy of my logs if needed.

[jeremystretch]

Table configuration for the child prefixes view just recently added in #6872 (in v2.11.12), but it seems to have broken in v3.0.

[jeremystretch]

Looks like something got lost in the merge when we switched from a context variable to a template tag for the table configuration form.
