为什么大摇大摆会引发不清楚的错误-Django

Question

我有一个 django rest 后端应用程序，我使用 swagger 来查看我的 api 并将其记录到 FE。

这工作正常，但我做了一些更改，现在我收到此错误：

Internal Server Error: /

HTTP GET / 500 [0.15, 127.0.0.1:44214]

这个错误不是很清楚，因为 AutoSchema 不是我的代码的一部分，而且回溯没有告诉我问题出在我的代码中的什么地方。我做了太多更改，无法一一检查并检查是哪一个导致了这种情况。

以前有人遇到过这个问题吗？关于如何调试以查找导致此问题的更改的任何想法？

我运行遇到了同样的问题，这里描述了修复：https://www.django-rest-framework.org/community/3.10-announcement/

总而言之，Django Rest Framework 3.10（几天前发布）弃用了基于 CoreAPI 的模式生成，并引入了 OpenAPI 模式生成。目前要继续使用 django-rest-swagger，您需要通过将以下配置添加到设置文件来 re-enable CoreAPI 架构生成：

REST_FRAMEWORK = { ... 'DEFAULT_SCHEMA_CLASS': 'rest_framework.schemas.coreapi.AutoSchema' }
