Sorting subsets of objects broken for Django 4.2?

[eastface]

I am using a sorting_filters tuple to filter subsets of objects. This was working fine previously, and I suspect it stopped working when I upgraded to Django 4 (though I haven't fully checked that).

The error I see is

Cannot resolve keyword 'sort_filter' into field.

And debug shows

filters {'sort_filter': '0'}
request <WSGIRequest: GET '/admin/gallery/slide/?sort_filter=0'>

at line 60 in changelist_view of django-admin-sortable/adminsortable/admin.py.

It looks to me like the sort_filter in the querystring should not be parsed into filters. This is done in the get_querystring_filters method which already ignores keys IGNORED_PARAMS and PAGE_VAR. By also ignoring sort_filter and e (which can also get in there). My code is working again.

I hope this is useful and allows someone to spot the correct quick fix.

And just in case anyone needs a quick workaround, for me it works to override get_querystring_filters in my admin class:

class SlideAdmin(SortableAdmin):
    list_display = ('headline', 'strapline', 'link', )

    def get_querystring_filters(self, request):
        filters = super().get_querystring_filters(request)
        return {k: v for k, v in filters.items() if k != 'sort_filter' and k != 'e'}
