rails/railties/CHANGELOG.md

• Show relevant commands when calling help

  When running rails -h or just rails outside a Rails application, Rails outputs all options for running the rails new command. This can be confusing to users when they probably want to see the common Rails commands.

  Instead, we should always show the common commands when running rails -h inside or outside a Rails application.

  As the relevant commands inside a Rails application differ from the commands outside an application, the help USAGE file has been split to show the most relevant commands for the context.

  Petrik de Heus

• Add Rails::HealthController#show and map it to /up for newly generated applications. Load balancers and uptime monitors all need a basic endpoint to tell whether the app is up. This is a good starting point that'll work in many situations.

  DHH

• Only use HostAuthorization middleware if config.hosts is not empty

  Hartley McGuire

• Raise an exception when a before_action's "only" or "except" filter options reference an action that doesn't exist. This will be enabled by default but can be overridden via config.

  # config/environments/production.rb
  config.action_controller.raise_on_missing_callback_actions = false
  

  Jess Bees

• Use physical processor count as the default Puma worker count in production. This can be overridden by setting ENV["WEB_CONCURRENCY"] or editing the generated "config/puma.rb" directly.

  DHH

• Bump required_rubygems_version from 1.8.11 to 3.3.13 or higher in order to support pre-release versions of Ruby when generating a new Rails app Gemfile.

  Yasuo Honda

• Add Docker files by default to new apps: Dockerfile, .dockerignore, bin/docker-entrypoint. These files can be skipped with --skip-docker. They're intended as a starting point for a production deploy of the application. Not intended for development (see Docked Rails for that).

  Example:

  docker build -t app .
  docker volume create app-storage
  docker run --rm -it -v app-storage:/rails/storage -p 3000:3000 --env RAILS_MASTER_KEY=<see config/master.key> app
  

  You can also start a console or a runner from this image:

  docker run --rm -it -v app-storage:/rails/storage --env RAILS_MASTER_KEY=<see config/master.key> app console
  

  To create a multi-platform image on Apple Silicon to deploy on AMD or Intel and push to Docker Hub for user/app:

  docker login -u <user>
  docker buildx create --use
  docker buildx build --push --platform=linux/amd64,linux/arm64 -t <user/image> .
  

  DHH, Sam Ruby

• Add ENV["SECRET_KEY_BASE_DUMMY"] for starting production environment with a generated secret base key, which can be used to run tasks like assets:precompile without making the RAILS_MASTER_KEY available to the build process.

  Dockerfile layer example:

  RUN SECRET_KEY_BASE_DUMMY=1 bundle exec rails assets:precompile
  

  DHH

• Show descriptions for all commands in Rails help

  When calling rails help most commands missed their description. We now show the same descriptions as shown in rails -T.

  Petrik de Heus

• Always generate the storage/ directory with rails new to ensure there's a stable place to put permanent files, and a single mount point for containers to map. Then default sqlite3 databases to live there instead of db/, which is only meant for configuration, not data.

  DHH

• Rails console now disables IRB's autocompletion feature in production by default.

  Setting IRB_USE_AUTOCOMPLETE=true can override this default.

  Stan Lo

• Add config.precompile_filter_parameters, which enables precompilation of config.filter_parameters using ActiveSupport::ParameterFilter.precompile_filters. Precompilation can improve filtering performance, depending on the quantity and types of filters.

  config.precompile_filter_parameters defaults to true for config.load_defaults 7.1 and above.

  Jonathan Hefner

• Add after_routes_loaded hook to Rails::Railtie::Configuration for engines to add a hook to be called after application routes have been loaded.

  MyEngine.config.after_routes_loaded do
    # code that must happen after routes have been loaded
  end
  

  Chris Salzberg

• Send 303 See Other status code back for the destroy action on newly generated scaffold controllers.

  Tony Drake

• Add Rails.application.deprecators as a central point to manage deprecators for an application.

  Individual deprecators can be added and retrieved from the collection:

  Rails.application.deprecators[:my_gem] = ActiveSupport::Deprecation.new("2.0", "MyGem")
  Rails.application.deprecators[:other_gem] = ActiveSupport::Deprecation.new("3.0", "OtherGem")
  

  And the collection's configuration methods affect all deprecators in the collection:

  Rails.application.deprecators.debug = true
  
  Rails.application.deprecators[:my_gem].debug
  # => true
  Rails.application.deprecators[:other_gem].debug
  # => true
  

  Additionally, all deprecators in the collection can be silenced for the duration of a given block:

  Rails.application.deprecators.silence do
    Rails.application.deprecators[:my_gem].warn    # => silenced (no warning)
    Rails.application.deprecators[:other_gem].warn # => silenced (no warning)
  end
  

  Jonathan Hefner

• Move dbconsole logic to Active Record connection adapter.

  Instead of hosting the connection logic in the command object, the database adapter should be responsible for connecting to a console session. This patch moves #find_cmd_and_exec to the adapter and exposes a new API to lookup the adapter class without instantiating it.

  Gannon McGibbon, Paarth Madan

• Add Rails.application.message_verifiers as a central point to configure and create message verifiers for an application.

  This allows applications to, for example, rotate old secret_key_base values:

  config.before_initialize do |app|
    app.message_verifiers.rotate(secret_key_base: "old secret_key_base")
  end
  

  And for libraries to create preconfigured message verifiers:

  ActiveStorage.verifier = Rails.application.message_verifiers["ActiveStorage"]
  

  Jonathan Hefner

• Support MySQL's ssl-mode option for the dbconsole command.

  Verifying the identity of the database server requires setting the ssl-mode option to VERIFY_CA or VERIFY_IDENTITY. This option was previously ignored for the dbconsole command.

  Petrik de Heus

• Delegate application record generator description to orm hooked generator.

  Gannon McGibbon

• Show BCC recipients when present in Action Mailer previews.

  Akshay Birajdar

• Extend routes --grep to also filter routes by matching against path.

  Example:

  > bin/rails routes --grep /cats/1
  Prefix Verb   URI Pattern         Controller#Action
     cat GET    /cats/:id(.:format) cats#show
         PATCH  /cats/:id(.:format) cats#update
         PUT    /cats/:id(.:format) cats#update
         DELETE /cats/:id(.:format) cats#destroy
  

  Orhan Toy

• Improve rails runner output when given a file path that doesn't exist.

  Tekin Suleyman

• config.allow_concurrency = false now use a Monitor instead of a Mutex

  This allows to enable config.active_support.executor_around_test_case even when config.allow_concurrency is disabled.

  Jean Boussier

• Add routes --unused option to detect extraneous routes.

  Example:

  > bin/rails routes --unused
  
  Found 2 unused routes:
  
  Prefix Verb URI Pattern    Controller#Action
     one GET  /one(.:format) action#one
     two GET  /two(.:format) action#two
  

  Gannon McGibbon

• Add --parent option to controller generator to specify parent class of job.

  Example:

  bin/rails g controller admin/users --parent=admin_controller generates:

  class Admin::UsersController < AdminController
    # ...
  end
  

  Gannon McGibbon

• In-app custom credentials templates are now supported. When a credentials file does not exist, rails credentials:edit will now try to use lib/templates/rails/credentials/credentials.yml.tt to generate the credentials file, before falling back to the default template.

  This allows e.g. an open-source Rails app (which would not include encrypted credentials files in its repo) to include a credentials template, so that users who install the app will get a custom pre-filled credentials file when they run rails credentials:edit.

  Jonathan Hefner

• Except for dev and test environments, newly generated per-environment credentials files (e.g. config/credentials/production.yml.enc) now include a secret_key_base for convenience, just as config/credentials.yml.enc does.

  Jonathan Hefner

• --no-* options now work with the app generator's --minimal option, and are both comprehensive and precise. For example:

  $ rails new my_cool_app --minimal
  Based on the specified options, the following options will also be activated:
  
    --skip-active-job [due to --minimal]
    --skip-action-mailer [due to --skip-active-job, --minimal]
    --skip-active-storage [due to --skip-active-job, --minimal]
    --skip-action-mailbox [due to --skip-active-storage, --minimal]
    --skip-action-text [due to --skip-active-storage, --minimal]
    --skip-javascript [due to --minimal]
    --skip-hotwire [due to --skip-javascript, --minimal]
    --skip-action-cable [due to --minimal]
    --skip-bootsnap [due to --minimal]
    --skip-dev-gems [due to --minimal]
    --skip-system-test [due to --minimal]
  
  ...
  
  $ rails new my_cool_app --minimal --no-skip-active-storage
  Based on the specified options, the following options will also be activated:
  
    --skip-action-mailer [due to --minimal]
    --skip-action-mailbox [due to --minimal]
    --skip-action-text [due to --minimal]
    --skip-javascript [due to --minimal]
    --skip-hotwire [due to --skip-javascript, --minimal]
    --skip-action-cable [due to --minimal]
    --skip-bootsnap [due to --minimal]
    --skip-dev-gems [due to --minimal]
    --skip-system-test [due to --minimal]
  
  ...
  

  Brad Trick and Jonathan Hefner

• Add --skip-dev-gems option to app generator to skip adding development gems (like web-console) to the Gemfile.

  Brad Trick

• Skip Active Storage and Action Mailer if Active Job is skipped.

  Étienne Barrié

• Correctly check if frameworks are disabled when running app:update.

  Étienne Barrié and Paulo Barros

• Delegate model generator description to orm hooked generator.

  Gannon McGibbon

• Execute rails runner scripts inside the executor.

  Enables error reporting, query cache, etc.

  Jean Boussier

• Avoid booting in development then test for test tasks.

  Running one of the rails test subtasks (e.g. test:system, test:models) would go through Rake and cause the app to be booted twice. Now all the test:* subtasks are defined as Thor tasks and directly load the test environment.

  Étienne Barrié

• Deprecate Rails::Generators::Testing::Behaviour in favor of Rails::Generators::Testing::Behavior.

  Gannon McGibbon

• Allow configuration of logger size for local and test environments

  config.log_file_size

  Defaults to 100 megabytes.

  Bernie Chiu

• Enroll new apps in decrypted diffs of credentials by default. This behavior can be opted out of with the app generator's --skip-decrypted-diffs flag.

  Jonathan Hefner

• Support declarative-style test name filters with bin/rails test.

  This makes it possible to run a declarative-style test such as:

  class MyTest < ActiveSupport::TestCase
    test "does something" do
      # ...
    end
  end
  

  Using its declared name:

  $ bin/rails test test/my_test.rb -n "does something"
  

  Instead of having to specify its expanded method name:

  $ bin/rails test test/my_test.rb -n test_does_something
  

  Jonathan Hefner

• Add --js and --skip-javascript options to rails new

  --js alias to rails new --javascript ...

  Same as -j, e.g. rails new --js esbuild ...

  --skip-js alias to rails new --skip-javascript ...

  Same as -J, e.g. rails new --skip-js ...

  Dorian Marié

• Allow relative paths with leading dot slash to be passed to rails test.

  Fix rails test ./test/model/post_test.rb to run a single test file.

  Shouichi Kamiya and oljfte

• Deprecate config.enable_dependency_loading. This flag addressed a limitation of the classic autoloader and has no effect nowadays. To fix this deprecation, please just delete the reference.

  Xavier Noria

• Define config.enable_reloading to be !config.cache_classes for a more intuitive name. While config.enable_reloading and config.reloading_enabled? are preferred from now on, config.cache_classes is supported for backwards compatibility.

  Xavier Noria

• Add JavaScript dependencies installation on bin/setup

  Add yarn install to bin/setup when using esbuild, webpack, or rollout.

  Carlos Ribeiro

• Use controller_class_path in Rails::Generators::NamedBase#route_url

  The route_url method now returns the correct path when generating a namespaced controller with a top-level model using --model-name.

  Previously, when running this command:

  bin/rails generate scaffold_controller Admin/Post --model-name Post
  

  the comments above the controller action would look like:

  # GET /posts
  def index
    @posts = Post.all
  end
  

  afterwards, they now look like this:

  # GET /admin/posts
  def index
    @posts = Post.all
  end
  

  Fixes #44662.

  Andrew White

• No longer add autoloaded paths to $LOAD_PATH.

  This means it won't be possible to load them with a manual require call, the class or module can be referenced instead.

  Reducing the size of $LOAD_PATH speed-up require calls for apps not using bootsnap, and reduce the size of the bootsnap cache for the others.

  Jean Boussier

• Remove default X-Download-Options header

  This header is currently only used by Internet Explorer which will be discontinued in 2022 and since Rails 7 does not fully support Internet Explorer this header should not be a default one.

  Harun Sabljaković

• Add .node-version files for Rails apps that use Node.js

  Node version managers that make use of this file: https://github.com/shadowspawn/node-version-usage#node-version-file-usage

  The generated Dockerfile will use the same node version.
