Clearing page length user preference breaks pagination

[devon-mar]

Deployment Type

Self-hosted

NetBox Version

v4.0.2

Python Version

3.10

Steps to Reproduce

1. Create a new user account
2. Visit a page that uses pagination. It should load properly.
3. Open /user/preferences/ and click the "X" on Page length.
4. Click Save.
5. Visit the page in step 2. An error should occur.

Expected Behavior

The page should load without an error.

Observed Behavior

<class 'TypeError'>

'<' not supported between instances of 'int' and 'str'

Python version: 3.10.14
NetBox version: 4.0.2
Plugins: 
  netbox_demo: 0.5.0

I believe this is because the paginate.per_page preference is an empty string:

GET /api/users/config/

{
    "ui": {
        "htmx_navigation": ""
    },
    "locale": {
        "language": ""
    },
    "pagination": {
        "per_page": "",
        "placement": "bottom"
    },
    "data_format": "json"
}

Therefore, per_page is set to "" instead of config.PAGINATE_COUNT: https://github.com/netbox-community/netbox/blob/4b2f26a8002a8f01e186211c648768892cc199c8/netbox/utilities/paginator.py#L90
