How can I recover from a Rails migration rollback?

To recover from a Rails migration rollback, you can re-run the migration using the command rails db:migrate. If you need to revert to a specific version, use rails db:migrate VERSION=your_version_number.

What if I lost data during the rollback?

If you lost data, check if you have backups. You can restore from a database backup if available. Otherwise, you may need to manually re-enter the lost data.

Is there a way to prevent data loss during migrations?

Yes, always back up your database before running migrations. You can also use the db:structure:dump command to create a schema file.

Can I test migrations before applying them?

Absolutely! You can use a staging environment to test migrations before applying them to production.
