How to rollback a specific migration

Question

I have the following migration file db\migrate\20100905201547_create_blocks.rb

How can I specifically rollback that migration file?

Answer 1

Hello @kartik,

Try this:

rake db:migrate:down VERSION=20100905201547

will roll back the specific file.

To find the version of all migrations, you can use this command:

rake db:migrate:status

Or, simply the prefix of the migration's file name is the version you need to rollback.

Hope this is helpfull!!

Thank You!!
