从两个不同的Django模型创建JSON嵌套输出

from django.db import models

class User(models.Model):
    name = models.CharField(max_length=100)
    email = models.EmailField()

class Post(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()
    user = models.ForeignKey(User, on_delete=models.CASCADE)

from rest_framework import serializers

class PostSerializer(serializers.ModelSerializer):
    class Meta:
        model = Post
        fields = ('title', 'content')

class UserSerializer(serializers.ModelSerializer):
    posts = PostSerializer(many=True)

    class Meta:
        model = User
        fields = ('name', 'email', 'posts')

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

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