无法在Django Rest Fram上获取ErrorResponse

Question

这是有效的：

class Right(ResponseMixin, View):
    """Right"""
    renderers = (JSONRenderer, XMLRenderer)

    def get(self, request, right_id):
        if not right_id:
            return self.render(
                Response(status.HTTP_400_BAD_REQUEST,
                         {"successful": False})
            )

这不是：

^{pr2}$

我收到一条错误消息，上面说：

错误响应位于/v1/右/ 未提供异常

或者：

Request Method: GET
Request URL: http://127.0.0.1:8000/v1/right/

有人知道“无例外供应”是什么意思吗？在

（注意，为了降低复杂性，我稍微修改了代码，但问题仍然存在…）

使用http://django-rest-framework.org/api-guide/exceptions.html，我将创建一个自定义异常，该异常将从APIException继承并引发该异常。这至少对我有用！在

我知道我指的是新的2.x版本的文档，而您所指的是0.4.x版本，但它允许其他查看者跟踪主题和文档，而且APIException类与上一个版本相比变化不大。在
