Yaml Db
= YamlDb
YamlDb is a database-independent format for dumping and restoring data. It complements the 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 only for the databases typically used by Rails apps. Users, permissions, schemas, triggers, and other advanced database features are not supported – by design.
Any database that has an ActiveRecord adapter should work.
Usagerake db:data:dump -> Dump contents of Rails database to db/data.yml rake db:data:load -> Load contents of db/data.yml into the database
Further, there are tasks db:dump and db:load which do the entire database (the equivalent of running db:schema:dump followed by db:data:load).
ExamplesOne common use would be to switch your data from one database backend to another. For example, let’s say you wanted to switch from SQLite to MySQL. You might execute the following steps:
1. rake db:dump
2. Edit config/database.yml and change your adapter to mysql, set up database params
3. mysqladmin create [database name]
4. rake db:load
