Django服务器返回不同的状态代码

Question

我使用django rest框架来实现一个简单的API。在我的view.py我有这样的方法：

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) 

因此，对于PUT和DELETE方法，我想返回一个错误405，但使用Django的测试服务器，我不断收到一个错误500：

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

任何人都知道为什么？

谢谢！

它看起来像你使用那里的Response类需要一个数据参数：

签名：Response(data, status=None, template_name=None, headers=None, content_type=None)

http://www.django-rest-framework.org/api-guide/responses

我只是在那里使用基本的HttpResponse。
