在DRF中如何将相关的模型放入序列化程序的一个字段中？

from rest_framework import serializers
from .models import RelatedModel

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

from rest_framework import serializers
from .models import MainModel

class MainModelSerializer(serializers.ModelSerializer):
    related_model = RelatedModelSerializer(many=True)  # 如果是多对多关系，使用many=True

    class Meta:
        model = MainModel
        fields = '__all__'

from rest_framework import generics
from .models import MainModel
from .serializers import MainModelSerializer

class MainModelListView(generics.ListAPIView):
    queryset = MainModel.objects.all()
    serializer_class = MainModelSerializer
