Rails migration: best way to retrieve current migration version

Question

Is there good way to retrieve migration version number?

I need to implement a method in a model which behave differently on and beyond a specific migration version.

Answer 1

There's a much nicer way: rake db:migrate:status

up     20120530222941  Create shenanigans
up     20120613030015  *** NO FILE ***

Indicating that I've deleted my latest migration file.

Or more simply:

> rake db:version
Current version: 20120613030015
