如何创建多个对象，以及提供了foreignkey字段的foreignkey？

from django.db import models

class Author(models.Model):
    name = models.CharField(max_length=100)
    # 其他字段...

class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.ForeignKey(Author, on_delete=models.CASCADE)
    # 其他字段...

python manage.py makemigrations
python manage.py migrate

from .models import Author, Book

# 创建作者对象
author1 = Author.objects.create(name='John')
author2 = Author.objects.create(name='Jane')

# 创建书籍对象并指定作者
book1 = Book.objects.create(title='Book 1', author=author1)
book2 = Book.objects.create(title='Book 2', author=author2)
