I submitted a patch for "rake db:migrate:status": https://rails.lighthouseapp.com/projects/8994/tickets/4947
José Valim asked me to email this list to get your feedback on it.
It is a rake task to display the current state of migrations by comparing db/migrate/* with schema_migrations.
The issue is that migrations are run from the command line yet from the command line there is no way to see their current state. It's a black box. You have to check the database directly. That's a tedious extra step.
And when running migrate up/down/redo, you need a migration version. There's no autocompletion, so that either means carefully typing out 14 numbers or leaving the command line to cut/paste from the filename. Another tedious step.
This rake task reveals the current state of all migrations and makes it easy to target those migrations you want to affect. I also believe that it will make migrations easier for beginners to manage.
Thoughts?
