Django Rest框架:只获取ManyToMany关系的特定值

from django.db import models

class Model1(models.Model):
    name = models.CharField(max_length=100)

class Model2(models.Model):
    name = models.CharField(max_length=100)
    models = models.ManyToManyField(Model1, related_name='model2s')

from rest_framework import serializers
from .models import Model1, Model2

class Model2Serializer(serializers.ModelSerializer):
    class Meta:
        model = Model2
        fields = '__all__'

from rest_framework import generics
from .models import Model2
from .serializers import Model2Serializer

class Model2ListAPIView(generics.ListAPIView):
    serializer_class = Model2Serializer

    def get_queryset(self):
        model1_id = self.request.query_params.get('model1_id')
        if model1_id:
            return Model2.objects.filter(models__id=model1_id)
        return Model2.objects.all()
