django还原最后一次迁移 [英] django revert last migration

问题描述

我已经进行了迁移，添加了一个新表，并希望将其还原并删除迁移，而不会创建新的迁移。

我该怎么做？是否有命令恢复最后的迁移，然后我可以简单地删除迁移文件？

解决方案

您可以通过迁移到以前的迁移。

例如，如果最后两次迁移是：

• 0010_previous_migration


• 0011_migration_to_revert

然后你会做：

  ./ manage.py migrate my_app 0010_previous_migration 
  

然后，您可以删除迁移 0011_migration_to_revert 。 p>

如果您使用的是Django 1.8+，您可以使用

显示所有迁移的名称 ./ manage.py showmigrations my_app 
  

要反转应用程序的所有迁移，您可以运行：

  ./ manage.py migrate my_app zero 
  

I've made a migration that added a new table and want to revert it and delete the migration, without creating a new migration.

How do I do it? Is there a command to revert last migration and then I can simply delete the migration file?

解决方案

You can revert by migrating to the previous migration.

For example, if your last two migrations are:

• 0010_previous_migration
• 0011_migration_to_revert

Then you would do:

./manage.py migrate my_app 0010_previous_migration 

You can then delete migration 0011_migration_to_revert.

If you're using Django 1.8+, you can show the names of all the migrations with

./manage.py showmigrations my_app

To reverse all migrations for an app, you can run:

./manage.py migrate my_app zero
