can i select a name for a key when using ndb?

[saintthor]

for db.expando E:

E( key_name = 'zzz' ).put()

will create an entity with a key named 'zzz'. but when using ndb.expando, it set an attribute named 'key_name ' with the value 'zzz'.

how to make the ndb work as db?

[Guido van Rossum]

Use E(id='zzz').put()
