我已经在谷歌应用引擎中上传了我的示例 CRUD 应用程序。但它出现了如下所示的错误，

我已经使用如下命令上传了代码，

appcfg.py 更新 mobihero

已成功部署。 请解决我的问题。谢谢.....

你会改变你的 Mysql 后端吗？

对在 Django 中使用 Google Cloud SQL 的支持由自定义 Django 数据库后端提供，该后端包装了 Django 的 MySQL 后端。

编辑你的 settings.py：

DATABASES = {
    'default': {
        'ENGINE': 'google.appengine.ext.django.backends.rdbms',
        'INSTANCE': 'my_project:instance1',
        'NAME': 'my_database',
    }
}
