ORM批量添加

# ########### Book是模型类 ###########
# 建一个空列表,盛放obj对象
lst_obj=[]
# 用for循环控制添加信息条数
for i in range(100):
# 创建图书对象,不懂可以看看添加数据的两种方法,其中一种是先创建对象
book=Book(title="book_%s"%i,price=i*i)
# 创建好的对象放在一个列表
book_list.append(book)
# 创建表记录
Book.objects.bulk_create(book_list)

    # publisher_list 必须是可迭代对象
    publish_list = []

        publish_list.append(publish_obj)
    models.Publish.objects.bulk_create(publish_list, 10)
