CHANGELOG.md

• Set action_mailer.default_url_options values in development and test.

  Prior to this commit, new Rails applications would raise ActionView::Template::Error if a mailer included a url built with a *_path helper.

  Steve Polito

• Introduce Rails::Generators::Testing::Assertions#assert_initializer

  Compliments the existing initializer generator action.

  assert_initializer "mail_interceptors.rb"

  Steve Polito

• Generate a .devcontainer folder and its contents when creating a new app.

  The .devcontainer folder includes everything needed to boot the app and do development in a remote container.

  The container setup includes:

  • A redis container for Kredis, ActionCable etc.
  • A database (SQLite, Postgres, MySQL or MariaDB)
  • A Headless chrome container for system tests
  • Active Storage configured to use the local disk and with preview features working

  If any of these options are skipped in the app setup they will not be included in the container configuration.

  These files can be skipped using the --skip-devcontainer option.

  Andrew Novoselac & Rafael Mendonça França

• Introduce SystemTestCase#served_by for configuring the System Test application server

  By default this is localhost. This method allows the host and port to be specified manually.

  class ApplicationSystemTestCase < ActionDispatch::SystemTestCase
    served_by host: "testserver", port: 45678
  end

  Andrew Novoselac & Rafael Mendonça França

• bin/rails test will no longer load files named *_test.rb if they are located in the fixtures folder.

  Edouard Chin

• Ensure logger tags configured with config.log_tags are still active in request.action_dispatch handlers

  KJ Tsanaktsidis

• Setup jemalloc in the default Dockerfile for memory optimization.

  Matt Almeida, Jean Boussier

• Commented out lines in .railsrc file should not be treated as arguments when using rails new generator command. Update ARGVScrubber to ignore text after # symbols.

  Willian Tenfen

• Skip CSS when generating APIs.

  Ruy Rocha

• Rails console now indicates application name and the current Rails environment:

  my-app(dev)> # for RAILS_ENV=development
  my-app(test)> # for RAILS_ENV=test
  my-app(prod)> # for RAILS_ENV=production
  my-app(my_env)> # for RAILS_ENV=my_env

  The application name is derived from the application's module name from config/application.rb. For example, MyApp will displayed as my-app in the prompt.

  Additionally, the environment name will be colorized when the environment is development (blue), test (blue), or production (red), if your terminal supports it.

  Stan Lo

• Ensure autoload_paths, autoload_once_paths, eager_load_paths, and load_paths only have directories when initialized from engine defaults. Previously, files under the app directory could end up there too.

  Takumasa Ochi

• Prevent unnecessary application reloads in development.

  Previously, some files outside autoload paths triggered unnecessary reloads. With this fix, application reloads according to Rails.autoloaders.main.dirs, thereby preventing unnecessary reloads.

  Takumasa Ochi

• Use oven-sh/setup-bun in GitHub CI when generating an app with Bun.

  TangRufus

• Disable pidfile generation in the production environment.

  Hans Schnedlitz

• Set config.action_view.annotate_rendered_view_with_filenames to true in the development environment.

  Adrian Marin

• Support the BACKTRACE environment variable to turn off backtrace cleaning.

  Useful for debugging framework code:

  BACKTRACE=1 bin/rails server

  Alex Ghiculescu

• Raise ArgumentError when reading config.x.something with arguments:

  config.x.this_works.this_raises true # raises ArgumentError

  Sean Doyle

• Add default PWA files for manifest and service-worker that are served from app/views/pwa and can be dynamically rendered through ERB. Mount these files explicitly at the root with default routes in the generated routes file.

  DHH

• Updated system tests to now use headless Chrome by default for the new applications.

  DHH

• Add GitHub CI files for Dependabot, Brakeman, RuboCop, and running tests by default. Can be skipped with --skip-ci.

  DHH

• Add Brakeman by default for static analysis of security vulnerabilities. Allow skipping with --skip-brakeman option.

  vipulnsward

• Add RuboCop with rules from rubocop-rails-omakase by default. Skip with --skip-rubocop.

  DHH and zzak

• Use bin/rails runner --skip-executor to not wrap the runner script with an Executor.

  Ben Sheldon

• Fix isolated engines to take ActiveRecord::Base.table_name_prefix into consideration. This will allow for engine defined models, such as inside Active Storage, to respect Active Record table name prefix configuration.

  Chedli Bourguiba

• Fix running db:system:change when the app has no Dockerfile.

  Hartley McGuire

• In Action Mailer previews, list inline attachments separately from normal attachments. For example, attachments that were previously listed like

  Attachments: logo.png file1.pdf file2.pdf

  will now be listed like

  Attachments: file1.pdf file2.pdf (Inline: logo.png)

  Christian Schmidt and Jonathan Hefner

• In mailer preview, only show SMTP-To if it differs from the union of To, Cc and Bcc.

  Christian Schmidt

• Enable YJIT by default on new applications running Ruby 3.3+.

  Adds a config/initializers/enable_yjit.rb initializer that enables YJIT when running on Ruby 3.3+.

  Jean Boussier

• In Action Mailer previews, show date from message Date header if present.

  Sampat Badhe

• Exit with non-zero status when the migration generator fails.

  Katsuhiko YOSHIDA

• Use numeric UID and GID in Dockerfile template

  The Dockerfile generated by rails new sets the default user and group by name instead of UID:GID. This can cause the following error in Kubernetes:

  container has runAsNonRoot and image has non-numeric user (rails), cannot verify user is non-root
  

  This change sets default user and group by their numeric values.

  Ivan Fedotov

• Disallow invalid values for rails new options.

  The --database, --asset-pipeline, --css, and --javascript options for rails new take different arguments. This change validates them.

  Tony Drake, Akhil G Krishnan, Petrik de Heus

• Conditionally print $stdout when invoking run_generator.

  In an effort to improve the developer experience when debugging generator tests, we add the ability to conditionally print $stdout instead of capturing it.

  This allows for calls to binding.irb and puts work as expected.

  RAILS_LOG_TO_STDOUT=true ./bin/test test/generators/actions_test.rb

  Steve Polito

• Remove the option config.public_file_server.enabled from the generators for all environments, as the value is the same in all environments.
