You're seeing this error because you have DEBUG = True in your
Django settings file. Change that to False, and Django will
display a standard 500 page.
By default, Django stores sessions in your database (using the model django.contrib.sessions.models.Session). Though this is convenient, in some setups it’s faster to store session data elsewhere, so Django can be configured to store session data on your filesystem or in your cache.
Django 似乎将会话存储在您的数据库中，并使用其 ORM 框架。由于您使用 NDB，因此您不能依赖其 ORM 框架。基本上，你有两个选择。
- 将会话数据存储在别处。例如，您可以使用 cookie-based sessions
- 您可以使用支持 App Engine 的 Django-nonrel 和 Cloud Datastore

You're seeing this error because you have DEBUG = True in your
Django settings file. Change that to False, and Django will
display a standard 500 page.
By default, Django stores sessions in your database (using the model django.contrib.sessions.models.Session). Though this is convenient, in some setups it’s faster to store session data elsewhere, so Django can be configured to store session data on your filesystem or in your cache.
Django 似乎将会话存储在您的数据库中，并使用其 ORM 框架。由于您使用 NDB，因此您不能依赖其 ORM 框架。基本上，你有两个选择。
- 将会话数据存储在别处。例如，您可以使用 cookie-based sessions
- 您可以使用支持 App Engine 的 Django-nonrel 和 Cloud Datastore
