封装一个CommonResponse对象

需求: 封装CommonResponse对象使用方法如下

return CoomonResponse('100','成功',boo_ser.data)
return CoomonResponse('101','验证失败',boo_ser.errors)

实现:

from rest_framework.response import Response


class CommonResponse(Response):
    def __init__(self, code=1000, messages='ok', results=None,
                 status=None, template_name=None, headers=None,
                 exception=False, content_type=None,
                 **kwargs):
        data = {
            'code': code,
            'messages': messages,
        }
        data.update(kwargs)
        if results:
            data['results'] = results
        super().__init__(data=data, status=status,
                         template_name=template_name, headers=headers,
                         exception=exception, content_type=content_type)

视图中使用:

class BookListCrateView(GenericAPIView):
    # queryset = Book.objects.all()
    queryset = Book.objects
    serializer_class = BookModelSerializer

    def get(self, request):
        book_obj = self.get_queryset()
        serializer = self.get_serializer(instance=book_obj, many=True)
        return CommonResponse(results=serializer.data)

    def post(self, request):
        serializer = self.get_serializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            obj = CommonResponse(results=serializer.data)
        else:
            obj = CommonResponse(2000, '失败', error=serializer.errors)
        return obj
