如何自定义Mixin中的API从检索功能中自定义响应

我是Django的初学者，我已经用Mixin编写了基于类的API视图。功能很简单，即获取给定ID.IM的数据，粘贴了以下代码。

class GenericAPi(generics.GenericAPIView,mixins.ListModelMixin,mixins.RetrieveModelMixin):
serializer_class=ArticleSerializer
queryset=Article.objects.all()
lookup_field="id"
def get(self,request,id):
    if id:
        data=self.retrieve(request)
        return Response({"data":data.data,"status":data.status_code})
    else:
        return self.list(request)

这是我得到的响应

{“ id”：5，“ title”：“ loream”，“ wurs”：“ me”}

然后，我导航到Mixin中的检索功能，以对响应进行一些更改。

 def retrieve(self, request, *args, **kwargs):
    print('Retrieving')
    instance = self.get_object()
    serializer = self.get_serializer(instance)
    return Response({"result":serializer.data})

然后我打电话给API，但仍然得到同样的回应。如何自定义检索函数本身中的响应。

我需要这样的回应。

{“结果”：{“ id”：5，“ title”：“ loream”，“作者”：“ ipsum”}}}

I'm a beginner to Django, i have written a class-based API view with mixin. the functionality is simple i.e fetch the data of the given id.Im pasting the code below.

class GenericAPi(generics.GenericAPIView,mixins.ListModelMixin,mixins.RetrieveModelMixin):
serializer_class=ArticleSerializer
queryset=Article.objects.all()
lookup_field="id"
def get(self,request,id):
    if id:
        data=self.retrieve(request)
        return Response({"data":data.data,"status":data.status_code})
    else:
        return self.list(request)

this is the response I'm getting

{"id":5,"title":"loream","author":"me"}

then I navigate to the retrieve function in the mixin, to make some changes in the response.

 def retrieve(self, request, *args, **kwargs):
    print('Retrieving')
    instance = self.get_object()
    serializer = self.get_serializer(instance)
    return Response({"result":serializer.data})

and then I make a call to API, but still, I'm getting the same response.
How to customize the response in the retrieve function itself.

I need response like this.

{"result":{"id":5,"title":"loream","author":"ipsum"}}

我认为您不必在retievemodelmixin中自定义检索函数。

class GenericAPi(generics.GenericAPIView,mixins.ListModelMixin,mixins.RetrieveModelMixin):
    serializer_class=ArticleSerializer
    queryset=Article.objects.all()
    lookup_field="id"
    def get(self, request, id):
        if id:
            try:
                article = Article.objects.get(pk = id)
                return Response({"result": ArticleSerializer(article).data})
            except Article.DoesNotExist:
                return Response(status = status.HTTP_404_NOT_FOUND)
        return 
            return self.list(request, *args, **kwargs)

I think you don't have to customize retrieve function in the RetrieveModelMixin.

class GenericAPi(generics.GenericAPIView,mixins.ListModelMixin,mixins.RetrieveModelMixin):
    serializer_class=ArticleSerializer
    queryset=Article.objects.all()
    lookup_field="id"
    def get(self, request, id):
        if id:
            try:
                article = Article.objects.get(pk = id)
                return Response({"result": ArticleSerializer(article).data})
            except Article.DoesNotExist:
                return Response(status = status.HTTP_404_NOT_FOUND)
        return 
            return self.list(request, *args, **kwargs)
