为什么swagger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来查看和记录我的apis到FE。

这工作得很好，但我做了一些更改，现在我得到了这个错误：

Internal Server Error: /

HTTP GET / 500 [0.15, 127.0.0.1:44214]
/home/notsoshabby/Desktop/panda_pitch/django_project/settings.py 

这个错误不是很清楚，因为AutoSchema不是我代码的一部分，并且回溯没有告诉我问题在我代码中的什么地方。我做了太多的更改，不能一个接一个地去检查是哪一个引起的。

以前有没有人遇到过这个问题？关于如何调试以找出导致此问题的更改，有什么想法吗？

我遇到了同样的问题，修复方法如下所示：https://www.django-rest-framework.org/community/3.10-announcement/

总之，Django Rest Framework3.10(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中来重新启用CoreAPI模式生成：

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