在django中批量创建模型对象 [英] Bulk create model objects in django
问题描述
我有很多对象要保存在数据库中,所以我想用它创建模型实例。
I have a lot of objects to save in database, and so I want to create Model instances with that.
使用django,我可以创建所有的模型实例, MyModel(data)
,然后我想保存所有。
With django, I can create all the models instances, with MyModel(data)
, and then I want to save them all.
目前,我有一些像:
object = MyModel(name = item.name)
对象项目中的项目:
Currently, I have something like that:
for item in items:
object = MyModel(name=item.name)
object.save()
我想知道是否可以直接保存对象列表,例如: / p>
I'm wondering if I can save a list of objects directly, eg:
objects = []
for item in items:
objects.append(MyModel(name=item.name))
objects.save_all()
如何在一个事务中保存所有对象
How to save all the objects in one transaction?
