Django 1.8 - migrate 和 makemigrations 之间有什么区别？

Question

根据这里的文档: https://docs.djangoproject.com/en/1.8/topics/migrations/它说:

migrate, which is responsible for applying migrations, as well as unapplying and listing their status.

和

makemigrations, which is responsible for creating new migrations based on the changes you have made to your models.

据我所知，我先做

makemigrations

创建迁移文件然后执行

migrate

实际应用迁移？

请注意，我刚刚开始我的 Django 项目，并将我的应用程序添加到我的“installed_apps”列表中。之后，我做了

python manage.py runserver

它说

You have unapplied migrations; your app may not work properly until they are applied. Run 'python manage.py migrate' to apply them.

它没有提到任何关于运行 makemigrations 的事情。

Answer 1

根据Polls tutorial :

1. python manage.py makemigrations <app> : 创建迁移(生成 SQL 命令)。

2. python manage.py migrate : 运行迁移(执行 SQL 命令)。
