如何在Django REST Framework序列化程序中按字段类型对ManyToMany进行分类？

from rest_framework import serializers

class CustomSerializer(serializers.ModelSerializer):
    class Meta:
        model = YourModel
        fields = '__all__'

class CustomSerializer(serializers.ModelSerializer):
    def to_representation(self, instance):
        representation = super().to_representation(instance)
        categorized_fields = {}

        for field_name, field_value in representation.items():
            field = self.fields[field_name]

            if isinstance(field, serializers.ManyRelatedField):
                # 处理ManyToMany字段
                if field_name not in categorized_fields:
                    categorized_fields[field_name] = []
                categorized_fields[field_name].append(field_value)
            else:
                # 处理其他字段类型
                representation[field_name] = field_value

        representation.update(categorized_fields)
        return representation

    class Meta:
        model = YourModel
        fields = '__all__'

from rest_framework import generics

class YourView(generics.ListAPIView):
    queryset = YourModel.objects.all()
    serializer_class = CustomSerializer
