如何仅使用Key设置ReferenceProperty，而不是获取Model
考虑到数据存储区中模型的关键，我希望能够在不加载模型本身的情况下设置referenceproperty（因为我不需要该信息）。
例如：
class Book(db.Model):
author = db.StringProperty()
title = db.StringProperty()
class Review(db.Model):
book = db.ReferenceProperty(Book)
description = db.StringProperty()
Book
bookKey
Book
review = Review()
review.description = "It was ok, but I would recommend it for insomniacs."
review.book = bookKey
book = Book.get(bookKey) #I don't want this datastore access
#as I don't need the book object.
review = Review()
review.description = "It was ok, but I would recommend it for insomniacs."
review.book = book
get_value_for_datastore
ReferenceProperty

可以正常工作，并设置referenceproperty而无需获取模型。
