There are ways to get the key from a db.ReferenceProperty without
fetching the entity from the datastore.
I posted a metaclass that generated {name}_key fields for
db.ReferenceProperty s named {name}.
Also, there's get_value_for_datastore.
class A(db.Model):
pass
class B(db.Model):
a = db.ReferenceProperty(A)
a = A()
a.put()
b = B()
b.a = a.key()
assert a.key() == B.a.get_value_for_datastore(b)
