title: Learning Rails 3.0 - Migration Help - belongsTo
body: <p>I'm working on a photo gallery app. Photo has a belongsTo relationship to Album (Album has_many realtionship to Photo) How do I create the migration that adds this relationship to the database correctly? I have tried  - rails generate add_album_to_photo but that comes through as an empty migration. I could use a push in the right direction.</p>
