我可以在Graphene Django中的自定义类型下嵌套类似的模型关系吗？

from django.db import models

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

class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.ForeignKey(Author, on_delete=models.CASCADE, related_name='books')

from graphene_django import DjangoObjectType
import graphene

class AuthorType(DjangoObjectType):
    class Meta:
        model = Author
        fields = ('id', 'name', 'books')

class BookType(DjangoObjectType):
    class Meta:
        model = Book
        fields = ('id', 'title', 'author')

class Query(graphene.ObjectType):
    authors = graphene.List(AuthorType)

    def resolve_authors(self, info):
        return Author.objects.all()

schema = graphene.Schema(query=Query)

{
  authors {
    id
    name
    books {
      id
      title
    }
  }
}
