Cherry pick a migration
Raw
cherry-pick-migration.rb
## One way to do it is from the rails console:
require 'db/migrate/MIGRATION_FILE_NAME.rb'
# if using def change
MigrationClass.new.migrate(:down)
# if using up or down
MigrationClass.up
## Another way is using a rake task
rake db:migrate:up VERSION=20090408054532
# The second option is probably preferred because it updates the schema, however,
# it won't work if it has already behind or something.
