教程5：关系和超链接API错误教程链接地址是：https://www.django-rest-framework.org/tutorial/5-relationships-and-hyperlinked-apis/我尝试了查询相关的解决方案，在stackoverflow上也遇到了类似的问题，但经过测试，我仍然无法使用它们。
views.py

    queryset = Snippet.objects.all()
    serializer_class = SnippetSerializer

    queryset = User.objects.all()
    serializer_class = UserSerializer

        return Response(snippet.highlighted)

serializers.py

    class Meta:
