如何在Django RESTful API中序列化ManyToMany关系中的数据列表并正确创建嵌套对象？

from django.db import models

class Book(models.Model):
    title = models.CharField(max_length=100)
    authors = models.ManyToManyField('Author')

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

from rest_framework import serializers
from .models import Book, Author

class AuthorSerializer(serializers.ModelSerializer):
    class Meta:
        model = Author
        fields = '__all__'

class BookSerializer(serializers.ModelSerializer):
    authors = AuthorSerializer(many=True)

    class Meta:
        model = Book
        fields = '__all__'

    def create(self, validated_data):
        authors_data = validated_data.pop('authors')
        book = Book.objects.create(**validated_data)
        for author_data in authors_data:
            author, _ = Author.objects.get_or_create(**author_data)
            book.authors.add(author)
        return book

from rest_framework import viewsets
from .models import Book
from .serializers import BookSerializer

class BookViewSet(viewsets.ModelViewSet):
    queryset = Book.objects.all()
    serializer_class = BookSerializer

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

router = routers.DefaultRouter()
router.register(r'books', BookViewSet)

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