python - 应用程序引擎Python : AttributeError: 'module' object has no attribute 'Stock'

Question

我在生产中遇到此错误。在本地主机上它运行良好。

Traceback (most recent call last):
  File "/base/python_runtime/python_lib/versions/1/google/appengine/ext/webapp/_webapp25.py", line 701, in __call__

Stock 是我的模型中的一类。我也在本地主机上使用 python 2.5 进行了测试。

给出错误的行是访问memcache(get函数)。
我改变了项目，也许我放入memcache的数据类型不同。我有办法清理内存缓存上的数据吗？

有什么想法吗？

从版本 1.6.4 开始，管理控制台中就有了 Memcache Viewer。它包括一个“刷新缓存”按钮，可以完全满足您的需要。
