如何在Django rest框架中为多个类创建序列化器？

from rest_framework import serializers

class ClassASerializer(serializers.Serializer):
    # 定义ClassA的序列化字段
    field1 = serializers.CharField()
    field2 = serializers.IntegerField()

class ClassBSerializer(serializers.Serializer):
    # 定义ClassB的序列化字段
    field3 = serializers.CharField()
    field4 = serializers.IntegerField()

class ClassCSerializer(serializers.Serializer):
    # 定义ClassC的序列化字段
    field5 = serializers.CharField()
    field6 = serializers.IntegerField()

# 在视图中使用这些序列化器
class MyView(APIView):
    def get(self, request):
        class_a = ClassA.objects.all()
        class_b = ClassB.objects.all()
        class_c = ClassC.objects.all()

        # 分别对每个类进行序列化
        class_a_serializer = ClassASerializer(class_a, many=True)
        class_b_serializer = ClassBSerializer(class_b, many=True)
        class_c_serializer = ClassCSerializer(class_c, many=True)

        # 返回序列化后的数据
        return Response({
            'class_a': class_a_serializer.data,
            'class_b': class_b_serializer.data,
            'class_c': class_c_serializer.data
        })
