I am overriding the `get_queryset` method of the admin and returning the
following:
{{{
return
super().get_queryset(request).annotate(sites_list=ArrayAgg('sites__name',
default=Value([]), distinct=True))
}}}
The idea is to return a list of what sites a given record is associated
with. When there are no sites, I'd like it to return an empty list. The
docs suggest that the above should accomplish this, but it's returning
`[None]` instead. I tried replacing `Value([])` with `[]`, but results are
unchanged. If I replace it with `"TEST"`, I get an error "malformed array
literal: 'TEST'", so it is attempting to interact with the argument, but
both of the attempts at providing a list here are ignored. Any idea what
may be causing this?
