Python django none类型对象没有属性状态

我从Django得到以下错误：

非类型对象没有属性状态\ U代码

以下是日志输出的副本：

您正在对尚不存在的对象调用状态代码。向数据库添加一些测试数据。Nonetype相当于java的Null。。。对象为空。

为

institutes\u admin

URL提供服务的视图没有返回响应，因此当中间件尝试缓存它时，它正在死亡。您需要发布该视图的代码-请在此处发布，而不是在单独的粘贴站点上发布。

在您丢失响应对象的某个地方

如果Autologue有一个过程-反应方法，我会看看那里。如果您添加自动登录代码和视图，可能会很快找到问题。

我在尝试查看route my/history/页面时遇到了类似的异常错误，该页面从日志条目和所有历史对象中获取数据

此外，我还进行从xls工作表到RESTAPI框架的解析。有一次我在做从xls工作表到RESTAPI框架的解析。所以我在查看管理页面时丢失了一些对象（数据）。当我从postgresql中删除数据库时。重新创建了everything数据库，创建了超级用户kids

再次将解析文件中的数据转储到REST API。这次一切都解决了

在你的情况下，我可能完全错了，但我克服了下面的错误

谢谢你，如果粘贴错误，它看起来不会那么长，如果你希望我会注意的话-这是一个更基本的错误，当settings.py文件出错时会出现。我也有同样的情况，但我无法弄清楚。另一个无关的注意事项是：如果我没记错，django文档建议在最后一个元组后面也加一个逗号，因此，您可能应该在“mysite.memory_me.views.autologue”之后添加一个逗号。您可以粘贴映射到institutes_admin url的视图代码吗？2个可能的错误。。您的视图没有返回HttpResponse，或者您的自动中间件没有正确返回响应。。你能发布（像其他人问的那样）你的管理视图和你的中间件代码吗？数据库中的测试数据不会解决任何问题——django技术上不需要数据库。问题在于缺乏回应，只有匆忙才能得到这样的答案。
