如何在Django Rest框架中序列化两个模型的自定义数据集

from rest_framework import serializers
from .models import Model1, Model2

class CustomSerializer(serializers.Serializer):
    model1_field = serializers.CharField()
    model2_field = serializers.CharField()
    related_field = serializers.SerializerMethodField()

    def get_related_field(self, obj):
        # 自定义获取关系字段的方法
        # 可以在这里进行额外的数据处理或查询
        return obj.model2.related_field

from rest_framework import generics
from .serializers import CustomSerializer
from .models import Model1

class Model1ListView(generics.ListAPIView):
    queryset = Model1.objects.all()
    serializer_class = CustomSerializer

from django.urls import path
from .views import Model1ListView

urlpatterns = [
    path('model1/', Model1ListView.as_view(), name='model1-list'),
]
