我正在尝试部署Django网站，以便使用应用程序引擎共享笔记。
一切正常，直到我尝试通过应用程序界面或管理界面将文件上传到数据库中，因为它会导致500 Server error。
我经历了类似的问题，我知道此错误不是由应用程序引擎引起的，但我真的很困惑，因为它在本地可以正常工作。
我能够将文件上传到通过云代理连接它的数据库。
我试图检查日志并进行调试，但是没有提供任何线索。
更多信息： 部署设置设置DEBUG = True时，上传时显示此错误...

您似乎面临的错误是因为您正在将文件写入实例的文件系统中。根据{{3}}，您只能将临时文件写入目录/tmp。请记住，这样做将使用RAM内存（而不是存储空间），并且仅在创建文件的实例上可用。
如果您打算保留文件，则应the documentation。
