对象的对象JSON响应来自Django后端的React Redux前端

Question

这是Django在前端( JSON对象数组)调用axios时的响应。

[
    {
        "id": 1,
        "title": "How to create a django-react app",
        "body": "You should first do this stuff and that"
    },
    {
        "id": 5,
        "title": "How to connect django with react",
        "body": "Get this and that stuff"
    }
]

但这是我想要的响应(JSON对象的JSON对象)。Python字典与Javascript对象或Hashmap相同吗？有什么中间件可以用来转换形状吗？这是serializers.py需要做的工作还是views.py需要完成的工作？如何将响应从对象数组更改为一个或多个对象？

{
    1: {
        "id": 1,
        "title": "How to create a django-react app",
        "body": "You should first do this stuff and that"
    },
    5: {
        "id": 5,
        "title": "How to connect django with react",
        "body": "Get this and that stuff"
    }
}

serializers.py

class ArticleSerializer(serializers.ModelSerializer):
    class Meta:
        model = Article
        fields = '__all__'

views.py

class ArticleViewSet(ViewSet):
    queryset = Article.objects.all()

    def list(self, request):
        serializer = ArticleSerializer(ArticleViewSet.queryset, many=True)
        return Response(serializer.data)

    def retrieve(self, request, pk=None):
        article = get_object_or_404(ArticleViewSet.queryset, pk=pk)
        serializer = ArticleSerializer(article, many=False)
        return Response(serializer.data)

您应该能够在ArticleViewSet的list方法中构建一个字典：

class ArticleViewSet(ViewSet):
    queryset = Article.objects.all()

    def list(self, request):
        serializer = ArticleSerializer(ArticleViewSet.queryset, many=True)
        return Response({article['id']: article for article in serializer.data})

    def retrieve(self, request, pk=None):
        # ...
