Django / Django rest framework 查看未捕获的异常

Question

当我的设置中有 DEBUG=True 时，我会看到以下错误

Traceback:

Exception Type: ValidationError at /company/api/company/
Exception Value: {'id': ['Company with this Id already exists.']}

模型抛出错误，但其余框架视图正在调用 455. self.raise_uncaught_exception(exc)

我怎样才能让rest框架使用django模型中的异常？我认为这会自动处理，因为异常包含有关问题的信息。

当它被退回时，我只有一个带有<h1>Server error<h1> 的 500。

我不会假设我必须捕获异常并对其进行一些特殊处理，因为它是一个基本的 django ValidationError。

这个问题是不是因为rest框架也有ValidationError类型？

来自 drf 文档：

处理的异常有：

在 REST 框架内引发的 APIException 的子类。

Django 的 Http404 异常。

Django 的 PermissionDenied 异常。

所以没有。 drf 不会处理您所指的异常。

这里说你可以实现自己的异常处理： https://www.django-rest-framework.org/api-guide/exceptions/#custom-exception-handling
