为了重置我的应用程序，我运行了这个：

./manage.py reset node

它给了我这个错误输出：

如何在 Django-nonrel 中重置模型？

./manage.py reset node

执行sqlreset为给定的应用程序创建 DROPT TABLE 和 CREATE TABLE SQL 语句。

https://docs.djangoproject.com/en/1.3/ref/django-admin/#reset-appname-appname

这不适用于 App Engine 数据存储区，因为数据存储区是无模式的，因此不需要 CREATE/DROP 表命令。

如果要从数据存储区中删除现有模型，可以使用App Engine 开发控制台删除模型的所有实体（只需确保在访问开发控制台时使用正确的端口）。
