如何使用DRF串行器将连接表中的数据添加到多对多字段中？

from rest_framework import serializers

class MySerializer(serializers.ModelSerializer):
    m2m_field = serializers.SerializerMethodField()

    def get_m2m_field(self, obj):
        # 获取连接表中的数据
        m2m_data = obj.connected_table.all()
        # 返回连接表数据的序列化结果
        return AnotherSerializer(m2m_data, many=True).data

    class Meta:
        model = MyModel
        fields = ('m2m_field', 'other_fields')

from rest_framework import generics

class MyView(generics.ListAPIView):
    queryset = MyModel.objects.all()
    serializer_class = MySerializer
