有没有办法在DRF中获取所有与ManyToMany相关的对象？

from rest_framework import serializers
from .models import MyModel, RelatedModel

class RelatedModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = RelatedModel
        fields = '__all__'

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

    def get_related_objects(self, obj):
        related_objects = obj.related_field.all()  # 获取与ManyToMany关系相关的对象
        serializer = RelatedModelSerializer(related_objects, many=True)
        return serializer.data

    class Meta:
        model = MyModel
        fields = '__all__'

from rest_framework import generics
from .serializers import MyModelSerializer
from .models import MyModel

class MyModelListAPIView(generics.ListAPIView):
    queryset = MyModel.objects.all()
    serializer_class = MyModelSerializer
