filter {{{__in}}} query does not guarantee to preserve order, so I usually
sort afterwards using python's sort.
However, in **django admin** I cannot sort queries using python's sort
when manipulating the QuerySet
since I have to return a QuerySet.
So, I'd do something like
{{{
queryset.filter(my_field__in=values).raw(
f'order by array_position(ARRAY[{ ",".join(["%s"]*len(values))
}]::varchar[], my_field)',
params=values)
}}}
but this does not work...
is there a solution here? (I cannot use raw either since I have a
queryset input argument to work with)
