我不能在Django rest api上连接两个模型并获得特定的输出

from django.db import models

class Model1(models.Model):
    # 模型1的字段

class Model2(models.Model):
    model1 = models.ForeignKey(Model1, on_delete=models.CASCADE)
    # 模型2的字段

from rest_framework import serializers

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

class Model1Serializer(serializers.ModelSerializer):
    model2_set = Model2Serializer(many=True, read_only=True)

    class Meta:
        model = Model1
        fields = '__all__'

from rest_framework import viewsets

class Model1ViewSet(viewsets.ModelViewSet):
    queryset = Model1.objects.all()
    serializer_class = Model1Serializer

from django.urls import include, path
from rest_framework import routers

router = routers.DefaultRouter()
router.register(r'model1', Model1ViewSet)

urlpatterns = [
    path('', include(router.urls)),
]
