SchemaValidations extends ActiveRecord to automatically create validations by inspecting the database schema. This makes your models more DRY as you no longer need to duplicate NOT NULL, unique, numeric and varchar constraints on the model level.

SchemaAssociations extends ActiveRecord to automatically create associations by inspecting the database schema. This is more more DRY than the standard behavior, for which in addition to specifying the foreign key in the migration, you must also specify complementary associations in two model files (e.g. a :belongs_to and a :has_many).

Extended support for foreign key constraints in ActiveRecord, including: definition as column attribute; deferrable; and SQLite3 support; cleaner dumps; and more!

Rack::Sprocketize is a piece of Rack Middleware which uses Sprockets to concatenate javascript files and then optionally compresses them. In a development environment, the files will be sprocketized on each request if there have been changes to the source files. In a production environment, the files will only be sprocketized one time, and only if there have been changes. Also, in a production environment, the files will be compressed by whichever javascript compressor is available.
