Question

我正在创建一个restapi视图，该视图应该是所有对象的一个端点。但是无论我做什么，它始终执行post方法。终端向我展示了例如patch方法已经执行，但始终执行确实发布并因此创建了一个新对象，并且它也没有删除该对象，它向我显示了正确的状态代码，但是该对象仍然存在。

这是我的观点

class StatusGET_New(

generics.ListCreateAPIView,
mixins.RetrieveModelMixin,
mixins.CreateModelMixin,
mixins.UpdateModelMixin,
mixins.DestroyModelMixin

):

queryset = Status.objects.all()
serializer_class = StatusSerializers
permission_classes = []

def perform_destroy(self, instance):
    if instance is not None:
        return instance.delete()
    return None

def get_queryset(self):
    qs = Status.objects.all()
    query = self.request.GET.get('q')
    if query is not None:
        qs = qs.filter(

            content__icontains = query

            )
    return qs   



def get_object(self):
    request = self.request
    passed_id = request.GET.get('pk',None)
    queryset = self.get_queryset()
    obj = None
    if passed_id is not None:
        obj = get_object_or_404(queryset,pk = passed_id)
        self.check_object_permissions(request,obj)
    return obj



def get(self,request,*args,**kwargs):
    passed_id = self.request.GET.get('pk',None)

    if passed_id is not None:
        return self.retrieve(request,*args,**kwargs)
    return super().get(request,*args,**kwargs)  


def post(self,request,*args,**kwargs):
    return self.create(request,*args,**kwargs)


def put(self,request,*args,**kwargs):
    url_passed_id = request.GET.get("pk",None)
    json_data = {}
    body_     = request.body
    if is_json(body_):
        json_data = json.loads(request.body)
    new_passed_id = json_data.get('pk',None)

    passed_id = url_passed_id or new_passed_id or None
    self.passed_id = passed_id
    return self.update(request,*args,**kwargs)



def patch(self,request,*args,**kwargs):
    url_passed_id = request.GET.get("pk",None)
    json_data = {}
    body_     = request.body
    if is_json(body_):
        json_data = json.loads(request.body)
    new_passed_id = json_data.get('pk',None)

    passed_id = url_passed_id or new_passed_id or None
    self.passed_id = passed_id
    return self.partial_update(body_,*args,**kwargs)




def delete(self,request,*args,**kwargs):
    url_passed_id = request.GET.get("pk",None)
    json_data = {}
    body_     = request.body
    if is_json(body_):
        json_data = json.loads(request.body)
    new_passed_id = json_data.get('pk',None)

    passed_id = url_passed_id or new_passed_id or None
    self.passed_id = passed_id
    return self.destroy(request,*args,**kwargs)

您正在混合ListCreateAPIView和mixins。相反，您应该将GenericAPIView与mixins一起使用，通常，mixins应该在继承顺序中排在GenericAPIView之前。

class StatusGET_New(
    generics.GenericAPIView,
    mixins.RetrieveModelMixin,
    mixins.CreateModelMixin,
    mixins.UpdateModelMixin,
    mixins.DestroyModelMixin):
...

但是从您的代码来看，您似乎想同时在同一视图中处理明细路径和列表路径，因此您需要的是视图集。所以应该像这样：

from restframework.viewsets import ModelViewSet

class StatusGET_New(ModelViewSet):
    ...

模型视图集已经具有所有这些方法的实现，因此您可能需要检查代码并在可能的情况下使用默认实现。

正如评论一样，您确实可以改善视图命名-类似于StatusView或StatusViewSet

我的rest api视图总是创建一个新对象，而不是put，delete和patch
