In Mongoid 4.0.0 field types can now use symbols as well as class names, fields can now be reset to their default values, documents now have a destroy! method that raises in case of destroy callback issues, Mongoid now uses ActiveSupport::LogSubscriber and ActiveSupport::Notifications, and there’s a lot more to read in the CHANGELOG including dozens of bug fixes. Since Mongoid follows semantic versioning, there are several backwards incompatible changes with the previous versions: it now only supports MongoDB 2.4.0, Document#metadata has been renamed to Document#relation_metadata, the Rails dependency on database rake tasks has been removed, and there are quite a few more you can find a beautifully detailed CHANGELOG.
Speaking lof CHANGELOGs, I want to encourage open source contributors who listen to us to provide a CHANGELOG as great as the one Mongoid provided for this new release. It’s important to present the new features, removed features, breaking changes and bug fixes in each version release. I’m a bit obsessed about this so I put up a little pamphlet called keepachangelog.com. Just remember: Friends don’t let friends dump git logs in CHANGELOGs.
If Rails isn’t your cup of tea and Sinatra doesn’t strike, there’s a new Ruby web framework on the block. It’s called Lotus and was written by Luca Guidi who describes it as a complete web framework with a strong emphasis on object-oriented design and testability. It’s Rack compliant like them, which seems like good news. The focus seems to be on simplicity — with standalone frameworks: Lotus::Controller, Lotus::Router, Lotus::Model, Lotus::View, etc. For instance you can use Lotus::Router to dispatch HTTP request to a pool of Sinatra applications. Aside from this, Luca emphasizes plain objects, a minimal DSL, and stable APIs. Lotus::View, contrary to Rails, separates view objects and templates. Lotus::Model tries to keep domain-specific logic away from persistence logic. Luca describes the documentation as extensive and at a high level it seems quite thorough. Anybody curious about web frameworks should give it a look and potentially offer Luca some feedback and contributions.
Thomas Eisenbarth wrote to us about a new book he’s co-written called Growing Rails Applications in Practice. Instead of advocating a big architectural rewrite, this book aims to provide actionable steps that every Rails developer can use -- like writing beautiful controllers, extracting service objects, organizing large codebases with namespacing, and much more. Ultimately, this book is about how to use discipline, consistency and organization to make your application grow more gently.
Some of the Austin, Texas Ruby community has organized a new conference called Keep Ruby Weird. It’s a one-day conference filled with... weird. It also has a pretty sweet logo. I hope there will be stickers. They’re still in the planning phase, so the Call for Proposals is open. Head over to keeprubyweird.com to submit a talk or sign up for their mailing list and get more info as it’s announced.
James Kassemi let us know about a very simple utility called ConfConf, which verifies the correctness of environment variables at application boot so you can fail fast when there's a configuration problem. After adding the gem to your Gemfile and bundling, you can just add an initializer for ConfConf that contains the environment variables you want to check for. If .. when booting your application, the environment variables are not present, a ConfConf::MissingConfigurationValueError is raised.
Listener Željko Filipin reminded us that we never mentioned the fact that RubyForge was shut down May 15th. If you still relied on the site it might be a good time to do a cursory check and make sure you don’t depend on it anymore.
