We make use of the pulp_href__in filter and it works great. We store pulp hrefs for some various things and we can easily look up the resources in pulp using this filter.

There is an edge case that I don't think it's properly handling though. It certain cases, the set will be empty and when we pass that to pulp, it seems that all results get returned. I think that no results should instead be returned.

Current behavior:

$ http :8080/pulp/api/v3/repositories/ pulp_href__in==
{
    "count": 1,
    "next": null,
    "previous": null,
    "results": [
        {
            "description": null,
            "latest_version_href": "/pulp/api/v3/repositories/deb/apt/1cc3ba78-bbf6-4373-b742-725785f010be/versions/0/",
            "name": "pmc_cli_test_repo_8fa0535e-c76f-4a60-8c1d-257290ec88c2",
            "pulp_created": "2023-09-18T12:46:41.212285Z",
            "pulp_href": "/pulp/api/v3/repositories/deb/apt/1cc3ba78-bbf6-4373-b742-725785f010be/",
            "pulp_labels": {},
            "remote": null,
            "retain_repo_versions": null,
            "versions_href": "/pulp/api/v3/repositories/deb/apt/1cc3ba78-bbf6-4373-b742-725785f010be/versions/"
        }
    ]
}

Expected behavior:

No results (ie []) get returned.

Looks like the problem is with django-filter: carltongibson/django-filter#1609

Handle empty list for pulp_href__in filter
58d6f09 
Fix bug where empty list for the pulp_href__in filter returns all
results instead of no results.

 The problem is that when using FilterMethod, django-filter just simply
ignores None and empty set and returns the full list of results:

https://github.com/carltongibson/django-filter/blob/e4a70a667a0bf3882fd44b557bc76583d2c65cd1/django_filters/filters.py#L804-L805

There's no way to update the method to prevent this since this logic
happens before the method is called. Instead, this change moves the
method to the filter and adds a None check.
