Django服务器返回不同的状态码

Question

我正在使用Django的REST框架来实现一个简单的API。在我的view.py文件里，我有这样一个方法：

def business_profile_detail(request, pk):
    """
    Retrieve, update or delete a profile.
    """
    try:
        profile = BusinessProfile.objects.get(pk=pk)
    except BusinessProfile.DoesNotExist:
        return HttpResponse(status=404)

    if request.method == 'GET':
        serializer = BusinessProfileSerializer(profile)
        return JSONResponse(serializer.data)

    elif request.method == 'PUT':
        """
        Method not supported yet
        """
        return Response(status=status.HTTP_405_METHOD_NOT_ALLOWED)

    elif request.method == 'DELETE':
        """
        Method not supported yet
        """
        return Response(status=status.HTTP_405_METHOD_NOT_ALLOWED)

所以对于PUT和DELETE这两种方法，我想返回一个错误代码405，但在使用Django测试服务器时，我总是收到一个错误代码500：

[17/Oct/2014 18:20:22] "DELETE /business/api/profile/2 HTTP/1.1" 500 60487

有人知道这是为什么吗？

谢谢！

看起来你用的这个 Response 类需要一个数据参数：

它的格式是：Response(data, status=None, template_name=None, headers=None, content_type=None)

你可以查看这个链接了解更多信息：http://www.django-rest-framework.org/api-guide/responses

我建议你直接使用一个基本的 HttpResponse。
