ListSerializer类 文档注解
ListSerializer类提供了序列化和一次验证多个对象的行为。您通常不需要ListSerializer直接使用，而应该many=True在实例化序列化程序时简单地通过。
class TrackListSerializer(serializers.ListSerializer):def create(self, validated_data):#validated_data会返回所有请求数组，而不是单个对象print(validated_data)books = [Track(**item) for item in validated_data]return Track.objects.bulk_create(books)def to_internal_value(self, data):print('to_internal_value',data)return data.get('data')
class TrackSerializer(serializers.ModelSerializer):# album = AlbumField(queryset=Album.objects.all())class AlbumSerilaizer(serializers.ModelSerializer):class Meta:model = Albumfields = "__all__"album = AlbumSerilaizer(many=False,read_only=True)class Meta:model = Trackfields = "__all__"list_serializer_class = TrackListSerializer
class RouterViewSet(viewsets.ModelViewSet):authentication_classes = ()serializer_class = TrackSerializerqueryset = Track.objects.all()def create(self, request, *args, **kwargs):data = request.data.get('data')if isinstance(data,dict):return super().create(request,*args,**kwargs)elif isinstance(data,list):
# 当many=True时，TrackSerializer会直接调用list_serializer_class属性ser=TrackSerializer(many=True,data=request.data)if ser.is_valid():ser.save()return Response(ser.data)
