使用SUDS Python WSDL客户端和Django Sentry，使用__sentry__属性进行异常

Question

在Django应用程序中使用SUDS时，除了Sentry错误记录外，我遇到了一个问题，即SUDS引发错误，Sentry试图处理它，失败并导致服务器500：

像Sentry和SUDS似乎打得不好......？

Answer 1

看起来SUDS实际上在其插件文件中抛出了错误的错误类型，因此Sentry无法处理它（Sentry尝试在引发异常的对象上调用__sentry__，我猜AttributeError将被退回.SUDS只会引发（旧式）异常......

请参阅：https://fedorahosted.org/suds/browser/trunk/suds/plugin.py#L208

也许修补它来引发一个AttributeError ......但这可能不是最好的解决方案......还有其他吗？
