Looking Backward: Ten Years on Rails

If you were curious about the milestones along the way of this 10-year journey, Luke Francl did a great writeup for that. If you prefer, you can always watch his presentation at this year's RailsConf instead.

Rails::Application#config_for

This was added a little while ago, but I don't think we have covered it yet. This handy utility method makes it easy to load custom configurations for the current environment, much like how database.yml works.

Add support for Postgresql JSONB

Active Record master now supports the "jsonb" data type on PostgreSQL with this pull request. This is a new feature on PostgreSQL 9.4+, enabling more efficient and sophisticated indexing and querying on JSON data. You can read more about it here.

New `type` option for `references` in migrations

t.references now takes a type option, handy when the table being referenced has a non-integer primary key column type (e.g. UUID).

Copy the default proc in `Hash#with_indifferent_access`

This pull request addresses a bug where calling with_indifferent_access on a hash does not copy over its default Proc.

Document the `digest` option in the scaffold generator

Did you know that you can use the digest option with the scaffold/model generator and have it add the appropriate database column, add has_secure_password in the model and so on?
