Rails 4.0 Whirlwind Tour

Rails 4.0 has yet to be released, but since it might be here by Christmas, it’s time to start getting ready.

Some Rails 4.0 features can be used today, and I describe how in the whirlwind tour I recently put together for the Atlanta Ruby Users Group.

Highlights of Rails 4.0

  • Rails.queue

  • strong_parameters

  • Turbolinks

  • Russian Doll Caching (cache_digests)

  • ActionController::Live (streaming)

  • PATCH verb

  • Routing concerns

  • Extraction of activeresource

  • ActiveRecord::Relation changes and improvements

  • Removal of plugin support (not gems; only those that are installed in vendor/plugins)

  • Removal of Rails 2 finder syntax

  • Deprecation of most dynamic finders

  • Deprecation of eager-evaluated scopes

I recommend watching the talk, and using the slide deck as a reference.
