How to rollback N numbers of migration in rails?
Sometimes, We need to rollback a specific number of migrations to undo series of changes.
To rollback n numbers of migrations, you can use the db:rollback command along with the STEP option, specifying the number of migrations to rollback.
For example, to rollback the last 3 migrations, you can run:
# RAILS >= 5.0
rails db:rollback STEP=3
# RAILS < 5.0
rake db:rollback STEP=3
This command will revert the last 3 migrations, undoing their changes to the database schema and data.
This is useful for reverting accidental changes, testing data migrations, or resetting the database to a previous state.
