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)

如何做到这一点，以便rest框架使用django模型中的异常？我认为这会得到自动处理，因为异常中包含有关发生问题的信息。

退货时，我仅有的是500个，<h1>Server error<h1>。

由于它是基本的django ValidationError，因此我不认为必须捕获该异常并对其进行一些特殊处理。

是由于rest框架也具有ValidationError类型引起的问题吗？

从drf文档：

处理的异常是：

REST框架内引发的APIException的子类。

Django的Http404异常。

Django的PermissionDenied异常。

没有。 drf不会处理您所指的异常。

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

Django / Django rest框架视图未捕获的异常
