rails/railties/CHANGELOG.md

Rails 4.0.0 (unreleased)

• Correctly handle SCRIPT_NAME when generating routes to engine in application that's mounted at a sub-uri. With this behavior, you should not use default_url_options[:script_name] to set proper application's mount point by yourself. Piotr Sarnacki

• config.threadsafe! is deprecated in favor of config.eager_load which provides a more fine grained control on what is eager loaded José Valim

• The migration generator will now produce AddXXXToYYY/RemoveXXXFromYYY migrations with references statements, for instance

  rails g migration AddReferencesToProducts user:references supplier:references{polymorphic}
  

  will generate the migration with:

  add_reference :products, :user, index: true
  add_reference :products, :supplier, polymorphic: true, index: true
  

  Aleksey Magusev

• Allow scaffold/model/migration generators to accept a polymorphic modifier for references/belongs_to, for instance

  rails g model Product supplier:references{polymorphic}
  

  will generate the model with belongs_to :supplier, polymorphic: true association and appropriate migration.

• Set config.active_record.migration_error to :page_load for development Richard Schneeman

• Add runner to Rails::Railtie as a hook called just after runner starts. José Valim & kennyj

• Add /rails/info/routes path, displays same information as rake routes Richard Schneeman & Andrew White

• Improved rake routes output for redirects Łukasz Strzałkowski & Andrew White

• Load all environments available in config.paths["config/environments"]. Piotr Sarnacki

• Add config.queue_consumer to allow the default consumer to be configurable. Carlos Antonio da Silva

• Add Rails.queue as an interface with a default implementation that consumes jobs in a separate thread. Yehuda Katz

• Remove Rack::SSL in favour of ActionDispatch::SSL. Rafael Mendonça França

• Remove Active Resource from Rails framework. Prem Sichangrist

• Allow to set class that will be used to run as a console, other than IRB, with Rails.application.config.console=. It's best to add it to console block. Piotr Sarnacki

  Example:

  # it can be added to config/application.rb
  console do
    # this block is called only when running console,
    # so we can safely require pry here
    require "pry"
    config.console = Pry
  end
  

• Add convenience hide! method to Rails generators to hide current generator namespace from showing when running rails generate. Carlos Antonio da Silva

• Scaffold now uses content_tag_for in index.html.erb José Valim

• Rails::Plugin has gone. Instead of adding plugins to vendor/plugins use gems or bundler with path or git dependencies. Santiago Pastorino

• Set config.action_mailer.async = true to turn on asynchronous message delivery Brian Cardarella
