在 Laravel 中回滚一个特定的迁移

发布于05月17日

I want

要仅回滚:

Rolled back: 2015_05_15_195423_alter_table_web_directories

I run

php artisan migrate:rollback，我的三次迁移正在倒退.

Rolled back: 2015_05_15_195423_alter_table_web_directories
Rolled back: 2015_05_13_135240_create_web_directories_table
Rolled back: 2015_05_13_134411_create_contacts_table

I delete

both of my web_directories and my contacts table unintentionally. I never want that to happen, and if I can rollback only that specific one, this disaster will never happen.

推荐答案

If you look in your migrations table, then you’ll see each migration has a batch number. So when you roll back, it rolls back each migration that was part of the last batch.

如果只想回滚最后一次迁移，那么只需将批次号增加1.然后下次运行rollback命令时，它只会回滚一次迁移，因为它是在自己的"批处理"中.

或者，从Laravel 5.3开始，您可以只运行:
