Querying ReferenceFields with MongoEngine
That is impossible by one query.
try this:
bars = Bar.objects.filter(value__lt = 1000)foo = Foo.objects.filter(bar__in = bars)More see. That test scripts.

If you using reference you can't query on referenced object fields. Because referencing done internally in driver and most drivers save referenced document id, collection name and db name (so you can query only on referenced document id).
Want query? Use embedding or make two separate queries.
