巩固Django南迁移 [英] Consolidating Django South Migrations
问题描述
在我的项目的初始阶段，我对模型做了很多更改，因此我结束了很多为我的应用程序生成的南迁移。在进入我的生产服务器执行迁移之前，是否可以以任何方式合并它们，所以我对每个应用程序没有一百万次迁移？
In the initial stages of my project I'm making a lot of changes to the models and thus I've ended up with a lot of south migrations being generated for my apps. Is it possible to consolidate them in any way before going to my production server to perform the migrations so I don't have like a million migrations for each app? And if so, how would I go about doing that?
推荐答案
您可以随时删除现有迁移和创建新的初始迁移。
You could always delete the existing migrations and create a new "initial" migration.
要执行此操作，您需要：
To do this, you will need to:
- 删除应用程序的迁移文件）
- 运行
./ manage.py convert_to_south myapp
- Remove the migration files for you app (remove the folder altogether)
- Run
./manage.py convert_to_south myapp
b $ b
这会让你对应于应用程序的状态当前状态的单个迁移。
This will leave you with a single migration corresponding to your app's state current state.
您可以随时将最新的迁移包装在一起：
Alternatively, you can always pack your latest migrations together:
- 删除要合并的迁移文件（仅当它们是最新的迁移） / li>
- 运行
./ manage.py schemamigration myapp
- Remove the migration files that you want to merge (only if they are the latest onces)
- Run
./manage.py schemamigration myapp
$ b b
这将创建一个与您删除的迁移相对应的新迁移。
This will create a new migration that will correspond to the migrations you removed.
这两个都可能会弄乱你的开发数据库。
Both of these will likely mess up your development DB.
