the problem is that I can't use SQL for this because this is a mixins that
I use for several objects (tables) because they all have this status
structure... yes it's quite difficult to do :
right now I'm on this stage, but still don't work
self.session.query(Object).outerjoin(ObjectStatus).outerjoin(Status)\
.group_by(Object).with_entities(Object,
func.max(Status.datum).label("status_datum")).subquery()
self.session.query(Object).join((sub, sub.c.id == Status.id))\
.filter(sub.c.statustype_id > 50)
