如何在DRF中只显示几个多对多关系？

from rest_framework import serializers

class MyModelSerializer(serializers.ModelSerializer):
    my_m2m_field = serializers.SerializerMethodField()

    def get_my_m2m_field(self, obj):
        # 过滤多对多关系，只选择需要显示的关系
        filtered_relations = obj.my_m2m_field.filter(...)  # 根据需要进行过滤

        # 返回过滤后的关系数据
        return MyRelatedModelSerializer(filtered_relations, many=True).data

    class Meta:
        model = MyModel
        fields = ('id', 'name', 'my_m2m_field')

class MyRelatedModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = MyRelatedModel
        fields = ('id', 'name')
