A simple migration, which runs pure Postgres SQL files.
<timestamp>_desc.sql files in
db/migrations (and corresponding
<timestamp>_desc_down.sql files if you want to be able to downgrade).
Then make sure that you either have a DATABASE_URL environment variable
ENV['DATABASE_URL'] = "postgres://user:passwd@host/db"
or if using sockets and default user
ENV['DATABASE_URL'] = "postgres:db"
namespace :db do task :setup => :environment do @migrator = PG::Migrator.new :dbname => 'mydb' end end
PG::Migrator takes the same arguments as PGconn.
Then as usually:
rake db:reset # drops the "public" schema in your database (not the database it self or any other schemas) rake db:migrate:up # runs all migrations in order rake db:migrate:down # runs the down migration for the latest applied migration
