如何在 Django rest 框架中为多个类创建序列化程序

Question

这是我的观点

class FindKeyWordNews(ListAPIView):
    queryset = []
    serializer_class = KeyWordSerializers
    def get_queryset(self):
        query_list = []
        keyword = self.kwargs.get("keyword")
        if keyword:
            republic = Republic.objects.filter(Q(headline__icontains=keyword)).order_by('-id')
            ndtv = Ndtv.objects.filter(Q(headline__icontains=keyword)).order_by('-id')
            indiatoday = Indiatv.objects.filter(Q(headline__icontains=keyword)).order_by('-id')
            hindustan = Hindustan.objects.filter(Q(headline__icontains=keyword)).order_by('-id')
            thehindu = Thehindu.objects.filter(Q(headline__icontains=keyword)).order_by('-id')
            zee = Zeenews.objects.filter(Q(headline__icontains=keyword)).order_by('-id')
            query_list = list(chain(republic, ndtv, indiatoday, hindustan, thehindu, zee))
        return query_list

我知道为单个模型创建序列化程序类

class NdtvSerializers(serializers.ModelSerializer):
    class Meta:
        model =Ndtv
        fields = ('headline', 'link', 'date', 'category', 'sentiment')

如何为上述视图的多个模型创建序列化程序类？模型的架构是相同的。

经过一些研究，我发现这个文档 rest 多个模型和包含 django rest 多个模型的步骤在这里 django rest 多个模型在项目中之后，我需要在我的视图中更改以下代码，并通过以下方式对所有模型使用序列化：

class FindKeyWordNews(ObjectMultipleModelAPIView):
    querylist = []
    def get_querylist(self, *args, **kwargs):
        keyword = self.kwargs.get("keyword")
        print(keyword)
        if keyword:
            queryset = [
                {'queryset': Republic.objects.filter(Q(headline__icontains=keyword)).order_by('-id'),
                 'serializer_class': RepublicSerializers},
                {'queryset': Ndtv.objects.filter(Q(headline__icontains=keyword)).order_by('-id'),
                 'serializer_class': NdtvSerializers},
                {'queryset': Indiatv.objects.filter(Q(headline__icontains=keyword)).order_by('-id'),
                 'serializer_class': IndiatvSerializers},
                {'queryset': Hindustan.objects.filter(Q(headline__icontains=keyword)).order_by('-id'),
                 'serializer_class': HindustanSerializers},
                {'queryset': Thehindu.objects.filter(Q(headline__icontains=keyword)).order_by('-id'),
                 'serializer_class': TheHinduSerializers},
                {'queryset': Zeenews.objects.filter(Q(headline__icontains=keyword)).order_by('-id'),
                 'serializer_class': ZeeNewsSerializers},
                {'queryset': News18.objects.filter(Q(headline__icontains=keyword)).order_by('-id'),
                 'serializer_class': News18Serializers},
                {'queryset': Firstpost.objects.filter(Q(headline__icontains=keyword)).order_by('-id'),
                 'serializer_class': FirstpostSerializers},
                {'queryset': Indianexpress.objects.filter(Q(headline__icontains=keyword)).order_by('-id'),
                 'serializer_class': IndianexpressSerializers},
                {'queryset': Oneindia.objects.filter(Q(headline__icontains=keyword)).order_by('-id'),
                 'serializer_class': OneindiaSerializers},
            ]
            return queryset

我很高兴我的代码工作正常并创建 api。
