rails--rails/railties/CHANGELOG.md

• Fix STATS_DIRECTORIES already defined warning when running rake from within the top level directory of an engine that has a test app.

  Fixes #20510

  Ersin Akinci

• Make enabling or disabling caching in development mode possible with rake dev:cache.

  Running rake dev:cache will create or remove tmp/caching-dev.txt. When this file exists config.action_controller.perform_caching will be set to true in config/environments/development.rb.

  Additionally, a server can be started with either --dev-caching or --no-dev-caching included to toggle caching on startup.

  Jussi Mertanen, Chuck Callebs

• Add a --api option in order to generate plugins that can be added inside an API application.

  Robin Dupret

• Fix NoMethodError when generating a scaffold inside a full engine.

  Yuji Yaginuma

• Adding support for passing a block to the add_source action of a custom generator

  Mike Dalton, Hirofumi Wakasugi

• assert_file understands paths with special characters (eg. v0.1.4~alpha+nightly).

  Diego Carrion

• Remove ContentLength middleware from the defaults. If you want it, just add it as a middleware in your config.

  Egg McMuffin

• Make it possible to customize the executable inside rerun snippets.

  Yves Senn

• Add support for API only apps. Middleware stack was slimmed down and it has only the needed middleware for API apps & generators generates the right files, folders and configurations.

  Santiago Pastorino & Jorge Bejar

• Make generated scaffold functional tests work inside engines.

  Yuji Yaginuma

• Generator a .keep file in the tmp folder by default as many scripts assume the existence of this folder and most would fail if it is absent.

  See #20299.

  Yoong Kang Lim, Sunny Juneja

• config.static_index configures directory index.html filename

  Set config.static_index to serve a static directory index file not named index. E.g. to serve main.html instead of index.html for directory requests, set config.static_index to "main".

  Eliot Sykes

• bin/setup uses built-in rake tasks (log:clear, tmp:clear).

  Mohnish Thallavajhula

• Fix mailer previews with attachments by using the mail gem's own API to locate the first part of the correct mime type.

  Fixes #14435.

  Andrew White

• Remove sqlite support from rails dbconsole.

  Andrew White

• Rename railties/bin to railties/exe to match the new Bundler executables convention.

  Islam Wazery

• Print bundle install output in rails new as soon as it's available.

  Running rails new will now print the output of bundle install as it is available, instead of waiting until all gems finish installing.

  Max Holder

• Respect pluralize_table_names when generating fixture file.

  Fixes #19519.

  Yuji Yaginuma

• Add a new-line to the end of route method generated code.

  We need to add a \n, because we cannot have two routes in the same line.

  arthurnn

• Add rake initializers.

  This task prints out all defined initializers in the order they are invoked by Rails. This is helpful for debugging issues related to the initialization process.

  Naoto Kaneko

• Created rake restart task. Restarts your Rails app by touching the tmp/restart.txt.

  Fixes #18876.

  Hyonjee Joo

• Add config/initializers/active_record_belongs_to_required_by_default.rb.

  Newly generated Rails apps have a new initializer called active_record_belongs_to_required_by_default.rb which sets the value of the configuration option config.active_record.belongs_to_required_by_default to true when ActiveRecord is not skipped.

  As a result, new Rails apps require belongs_to association on model to be valid.

  This initializer is not added when running rake rails:update, so old apps ported to Rails 5 will work without any change.

  Josef Šimánek

• delete operations in configurations are run last in order to eliminate 'No such middleware' errors when insert_before or insert_after are added after the delete operation for the middleware being deleted.

  Fixes #16433.

  Guo Xiang Tan

• Newly generated applications get a README.md in Markdown.

  Xavier Noria

• Remove the documentation tasks doc:app, doc:rails, and doc:guides.

  Xavier Noria

• Force generated routes to be inserted into config/routes.rb.

  Andrew White

• Don't remove all line endings from config/routes.rb when revoking scaffold.

  Fixes #15913.

  Andrew White

• Rename --skip-test-unit option to --skip-test in app generator

  Melanie Gilman

• Add the method_source gem to the default Gemfile for apps.

  Sean Griffin

• Drop old test locations from rake stats:

  • test/functional
  • test/unit

  Ravil Bayramgalin

• Update rake stats to correctly count declarative tests as methods in _test.rb files.

  Ravil Bayramgalin

• Remove deprecated test:all and test:all:db tasks.

  Rafael Mendonça França

• Remove deprecated Rails::Rack::LogTailer.

  Rafael Mendonça França

• Remove deprecated RAILS_CACHE constant.

  Rafael Mendonça França

• Remove deprecated serve_static_assets configuration.

  Rafael Mendonça França

• Use local variables in _form.html.erb partial generated by scaffold.

  Andrew Kozlov

• Add config/initializers/callback_terminator.rb.

  Newly generated Rails apps have a new initializer called callback_terminator.rb which sets the value of the configuration option config.active_support.halt_callback_chains_on_return_false to false.

  As a result, new Rails apps do not halt callback chains when a callback returns false; only when they are explicitly halted with throw(:abort).

  The terminator is not added when running rake rails:update, so returning false will still work on old apps ported to Rails 5, displaying a deprecation warning to prompt users to update their code to the new syntax.

  claudiob

• Generated fixtures won't use the id when generated with references attributes.

  Pablo Olmos de Aguilera Corradini

• Add --skip-action-mailer option to the app generator.

  claudiob

• Autoload any second level directories called app/*/concerns.
