如何删除Google App Engine中的所有数据存储？ [英] How to delete all datastore in Google App Engine?

问题描述

有谁知道如何删除 Google App Engine 中的所有数据存储？

$如果您在讨论实时数据存储，请打开您的应用程序的仪表板（在appengine上登录），然后打开数据存储库 - > dataviewer，为要删除的表选择所有行并点击删除按钮（您必须为所有表执行此操作）。
您可以通过remote_api以编程方式执行相同的操作（但我从来没有使用它）。

如果您正在讨论 开发数据库 只需要删除以下文件：./ WEB-INF / appengine-generated / local_db.bin。该文件将在您下次运行开发服务器时再次为您生成，并且您将拥有一个清晰的数据库。

确保以后清理项目。

这是当您开始使用Google应用程序引擎时可以派上用场的小问题之一。您会发现自己将对象保存到数据存储中，然后更改您的可持久实体的JDO对象模型，最终导致过时的数据导致您的应用在整个地方崩溃。

解决方案

If you're talking about the live datastore, open the dashboard for your app (login on appengine) then datastore --> dataviewer, select all the rows for the table you want to delete and hit the delete button (you'll have to do this for all your tables). You can do the same programmatically through the remote_api (but I never used it).

If you're talking about the development datastore, you'll just have to delete the following file: "./WEB-INF/appengine-generated/local_db.bin". The file will be generated for you again next time you run the development server and you'll have a clear db.

Make sure to clean your project afterwards.

This is one of the little gotchas that come in handy when you start playing with the Google Application Engine. You'll find yourself persisting objects into the datastore then changing the JDO object model for your persistable entities ending up with obsolete data that'll make your app crash all over the place.
