I think it should work :
res = Employee.gql("WHERE id = :1", some_user_id)
to_put = []
for r in res:
r.delivery_type = some_type
to_put.append(r)
db.put(to_put)
or
res = Employee.gql("WHERE id = :1", some_user_id)
for r in res:
r.delivery_type = some_type
db.put(r)
You change 'r' but you do nothing with it.
