Add default values to ActiveRecord models.

ActiveRecord defaults to immediately persisting changes to the database on assignments like user.session_ids = [1, 2]. This is a surprising behaviour that this gem aims to fix to be more coherent with regular assignments.

Adds deselect logic to ActiveRecord

Allow / disallow query execution through active record

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.

Duplicating ActiveRecords is easy again.
