activerecord_dumper

ActiveRecordDumper is a fork of YamlDb gem without any explicit Rails dependencies. This way it can be used by any AR-enabled app (e.g. Sinatra) without pulling whole Rails in. YamlDB/ActiveRecordDumper is a database-independent format for dumping and restoring data. It complements the database-independent schema format found in db/schema.rb. The data is saved into db/data.yml. This can be used as a replacement for mysqldump or pg_dump, but it only supports features found in ActiveRecord-based (Rails, etc.) apps. Users, permissions, schemas, triggers, and other advanced database features are not supported by design. Any database that has an ActiveRecord adapter should work.
