如何在Google App Engine上通过appcfg.py批量加载数据期间为数据库实体设置父级？ [英] How to set parent for datastrore entity during bulkloading data by appcfg.py on Google App Engine?

问题描述

我试图按照这里。我得到它的工作除了设置父实体，我似乎无法找到有关如何为导入创建的实体设置父实体的信息。你可以指点我正确的方向或为我的bulkloader.Loader实现提供一个代码片段吗？ 你需要覆盖Loader类的generate_key方法。有关详细信息，请参见此帖子。

I'm trying to bulkload data using appcfg.py as described here. I got it working except setting parent entity, I can't seem to find info on how to set a parent entity for entity being created by the import. Can you point me to the right direction or provide a code snippet for my bulkloader.Loader implementation?

解决方案

You need to override the generate_key method of your Loader class. See this post for details.
