Is custom queryset available #268

Open khaldon opened 4 years ago

khaldon commented 4 years ago

I want to use custom queryset I tried add that in to_queryset but doesn't work 

user = get_object_or_404(CustomUser,username=request.user.username)
results = RoomDocument.search().to_queryset(user.teacher_rooms.all())

You didn't understand the purpose of to_queryset.

The docstring says : This method return a django queryset from an elasticsearch result.

So RoomDocument.search().to_queryset() would simply (in most configuration) be equivalent to Room.objects.all() (but much more costly, for it rely on pks list)

I'm not aware of any method to do what you want to do. Use normal filter instead.

@khaldon, this place is for bug report. Please next, time use stackoverflow for support.

Maybe you wan't something like : 

user = get_object_or_404(CustomUser,username=request.user.username)
results = RoomDocument.search().filter("terms", _id=user.teacher_rooms.all())

But this is really wild guess, it depends on your schema and how you index rooms. Normally you 'd better have a teacher field in RoomDocument, to directly query on it, because normally elasticsearch is faster than your DB.

You should really read carefully the docs to understand things better. Elasticsearch DSL doc and Django Elasticsearch DSL doc

trying to do something like

es=EventDocument.search(body=body,size=10)['hits']['hits']

is it compatible?
