Note: I am not Django expert

The problem is that in your query

vals = Company.objects.filter(id__in=comp_ids)... 

you pass a bloated set of values and the underlaying engine cannot execute the query. Fortunately sqlalchemy, that you execute in that line, is lazy. You an execute a SELECT and then filter the entries "manually" without big performance penalties.

It would look more-less like that:

# here you should do a proper session.query(CompanyTable)
vals_all = Company.objects

vals_filtered = (item for item in vals_all if item.id in comp_ids)
vals_ordered = sorted(vals_filtered, key=attrgetter('name'))
vals_final = [(v.id, v.name) for v in vals_ordered]
