Rails Database Migration Status

Wondering if you've run the latest database migration? Wonder no more. There are better ways to find out this information than blindly running the migrations or waiting for your app to crash.

A handy command built into Rails is rake db:migrate:status. Here's some sample output from my blog's development PostgreSQL database:

% rake db:migrate:status

database: worth-chicago_co_development
