collection_name for ndb.KeyProperty


db.ReferenceProperty allowed for a collection_name argument that specified how the reference object R could query for the objects that contain R as a reference.
I don't see a similar argument for ndb.KeyProperty. How do folks get around that?
It took a little getting used to when I made the switch to ndb, but it is actually simpler. The collection_name is just syntactic sugar for a query, and you can do the query yourself:
MyEntity(ndb.Model):
a_key = ndb.KeyProperty()
entities = MyEntity.query(MyEntity.a_key == some_key)
