Some useful rake commands to remember

A migration file is an atomic change and undo change similar to changes made in database structure.


We'll need this everytime we create new migration file.
rake db:migrate
rake db:migrate_plugins RAILS_ENV=production

rake -T

And for more specific commands on db

rake -T db
