An example of an AI chatbot conversation about migration versions in Ruby on Rails.
What are migration versions in Ruby on Rails?
In Ruby on Rails, migration versions are timestamps that uniquely identify each migration file. They help manage the order of migrations.
How do I create a new migration with a specific version?
You can create a new migration with a specific version by using the command rails generate migration MigrationName and then manually adding the timestamp to the filename.
Can I roll back a migration to a specific version?
Yes, you can roll back to a specific migration version using the command rails db:rollback VERSION=timestamp where 'timestamp' is the version you want to roll back to.
What happens if I delete a migration file?
If you delete a migration file, it can cause issues with your database schema. It's best to use rails db:rollback to revert changes instead.
