import operator

from functools import reduce

results = qs.model.objects.raw(sql, sql_params)

obj_ranks = (obj.id for obj in results)
return_objs = []
# inject rank
for obj_id, objs.items():
    return_objs.append(qs.filter(id=obj_id))
if len(return_objs) > 0:
    qs = reduce(operator.or_, return_objs)
else:
    qs = qs.model.objects.none()

Mymodel.objects.filter(pk__in=[i.pk for i in Mymodel.objects.raw("SELECT * FROM mytable")])

This does not work for me
