大多数用户都在寻找@durdenk 在https://stackoverflow.com/a/39742847/3627387.但是 OP 要求的是一种在迁移后添加数据的方法，这就是为什么这是公认的答案.

原答案:

我认为您正在寻找的是 fixtures https://docs.djangoproject.com/en/1.10/howto/initial-data/

来自文档

<块引用>

在您第一次设置应用程序时，用硬编码数据预先填充您的数据库有时很有用.您可以通过夹具提供初始数据.

What's the most efficient way to manage default data after migrations?

It needs to handle situations such as, after I add a new table, it adds the default data for it.

解决方案

Update:

most users are looking for data migration as suggested by @durdenk in https://stackoverflow.com/a/39742847/3627387. But what OP was asking is about a way to add data after migrations, that is why this is accepted answer.

Original answer:

I think what you are looking for is fixtures https://docs.djangoproject.com/en/1.10/howto/initial-data/

From docs

It’s sometimes useful to pre-populate your database with hard-coded data when you’re first setting up an app. You can provide initial data via fixtures.
