Django rest框架:如何序列化多个表以获得组合JSON输出

from rest_framework import serializers
from .models import User, Order

class OrderSerializer(serializers.ModelSerializer):
    class Meta:
        model = Order
        fields = '__all__'  # 或者指定需要序列化的字段

class UserSerializer(serializers.ModelSerializer):
    orders = OrderSerializer(many=True, read_only=True)

    class Meta:
        model = User
        fields = '__all__'  # 或者指定需要序列化的字段

from rest_framework.views import APIView
from rest_framework.response import Response
from .serializers import UserSerializer

class UserView(APIView):
    def get(self, request):
        users = User.objects.all()
        serializer = UserSerializer(users, many=True)
        return Response(serializer.data)
