Rails 7.1.0.beta1 (September 13, 2023)

rails new --javascript generator now supports Bun
```
rails new my_new_app --javascript=bun
```
Jason Meller
bin/setup uses bun instead of yarn when generated an app with bun

Use bun install on bin/setup when using bun.

Cadu Ribeiro
config/application.rb now includes
```
config.autoload_lib(ignore: %w(assets tasks))
```
In practice, this means that new 7.1 applications autoload from lib out of the box.

Xavier Noria
Add an option to start rails console in sandbox mode by default

sandbox_by_default option is added to start rails console in sandbox mode by default. With this option turned on, --no-sandbox must be specified to start rails in non-sandbox mode.

Note that this option is ignored when rails environment is development or test.

Shouichi Kamiya
Omit webdrivers gem dependency from Gemfile template

Sean Doyle
Support filtering tests by line ranges

The new syntax allows you to filter tests by line ranges. For example, the following command runs tests from line 10 to 20.
```
$ rails test test/models/user_test.rb:10-20
```
Shouichi Kamiya, Seonggi Yang, oljfte, Ryohei UEDA
Update default scaffold templates to set 303 (See Other) as status code on redirect for the update action for XHR requests other than GET or POST to avoid issues (e.g browsers trying to follow the redirect using the original request method resulting in double PATCH/PUT)

Guillermo Iguaran
The new config.autoload_lib_once is similar to config.autoload_lib, except that it adds lib to config.autoload_once_paths instead.

By calling config.autoload_lib_once, classes and modules in lib can be autoloaded, even from application initializers, but won't be reloaded.

Please, see further details in the autoloading guide.

Xavier Noria
Add config.action_dispatch.debug_exception_log_level to configure the log level used by ActionDispatch::DebugExceptions.

The default is :fatal, but with load_defaults "7.1" the default will be :error.

Hartley McGuire
Add DATABASE option to railties:install:migrations

This allows you to specify which database the migrations should be copied to when running rails railties:install:migrations.
```
$ rails railties:install:migrations DATABASE=animals
```
Matthew Hirst
The new method config.autoload_lib(ignore:) provides a simple way to autoload from lib:
```
# config/application.rb
config.autoload_lib(ignore: %w(assets tasks))
```
Please, see further details in the autoloading guide.

Xavier Noria

Don't show secret_key_base for Rails.application.config#inspect.

Before:

Rails.application.config.inspect
"#<Rails::Application::Configuration:0x00000001132b02a0 @root=... @secret_key_base=\"b3c631c314c0bbca50c1b2843150fe33\" ... >"

After:

Rails.application.config.inspect
"#<Rails::Application::Configuration:0x00000001132b02a0>"

Petrik de Heus

Deprecate calling Rails.application.secrets.

Rails secrets have been deprecated in favor of credentials. Calling Rails.application.secrets should show a deprecation warning.

Petrik de Heus
Store secret_key_base in Rails.config for local environments.

Rails secrets have been deprecated in favor of credentials. For the local environments the secret_key_base is now stored in Rails.config.secret_key_base instead of the soft deprecated Rails.application.secrets.secret_key_base.

Petrik de Heus
Enable force_ssl=true in production by default: Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies

Justin Searls, Aaron Patterson, Guillermo Iguaran, Vinícius Bispo
Add engine's draw paths to application route set, so that the application can draw route files defined in engine paths.

Gannon McGibbon
Support VISUAL environment variable for commands which open an editor, and prefer it over EDITOR.

Summer ☀️
Add engine's test/fixtures path to fixture_paths in on_load hook if path exists and is under the Rails application root.

Chris Salzberg
bin/rails app:template now runs bundle install and any after_bundle blocks after the template is executed.

Jonathan Hefner and Gerry Caulfield
Enable passing column size to migration generator

Previously you could pass a limit to the migration generator:

rails generate migration CreateAuthor name:text{65535}

Now, a size attribute can be passed to the migration generator:

rails generate migration CreateAuthor name:text{medium}

This generates a migration which includes the size attribute:
```
class CreateAuthor < ActiveRecord::Migration[7.1]
  def change
    create_table :authors do |t|
      t.text :name, size: :medium
    end
  end
end
```
Josh Broughton, Hartley McGuire

Trying to set a config key with the same name of a method now raises:

config.load_defaults = 7.0
# NoMethodError: Cannot assign to `load_defaults`, it is a configuration method

Xavier Noria

Deprecate secrets:edit/show and remove secrets:setup

bin/rails secrets:setup has been deprecated since Rails 5.2 in favor of credentials. This command has been removed.

bin/rails secrets:show and bin/rails secrets:edit have been deprecated in favor of credentials.

Run bin/rails credentials:help for more information

Petrik de Heus
bin/rails --help will now list only framework and plugin commands. Rake tasks defined in lib/tasks/*.rake files will no longer be included. For a list of those tasks, use rake -T.

Jonathan Hefner
Allow calling bin/rails restart outside of app directory.

The following would previously fail with a "No Rakefile found" error.
```
$ blog/bin/rails restart
```
Petrik de Heus
Support prerelease rubies in Gemfile template if RubyGems version is 3.3.13 or higher.

Yasuo Honda, David Rodríguez

Autoloading setup honors root directories manually set by the user.

This is relevant for custom namespaces. For example, if you'd like classes and modules under app/services to be defined in the Services namespace without an extra app/services/services directory, this is now enough:

# config/initializers/autoloading.rb

# The namespace has to exist.
#
# In this example we define the module on the spot. Could also be created
# elsewhere and its definition loaded here with an ordinary `require`. In
# any case, `push_dir` expects a class or module object.
module Services; end

Rails.autoloaders.main.push_dir("#{Rails.root}/app/services", namespace: Services)

Check the autoloading guide for further details.

Xavier Noria

Railties now requires the irb gem as a dependency, which means when you install Rails, irb will also be installed as a gem. Rails will then use the installed version of irb for its console instead of relying on Ruby's built-in version. This ensures that Rails has access to the most up-to-date and reliable version of irb for its console.

Stan Lo
Use infinitive form for all rails command descriptions verbs.

Petrik de Heus
Credentials commands (e.g. bin/rails credentials:edit) now respect config.credentials.content_path and config.credentials.key_path when set in config/application.rb or config/environments/#{Rails.env}.rb.

Before:
- bin/rails credentials:edit ignored RAILS_ENV, and would always edit config/credentials.yml.enc.
- bin/rails credentials:edit --environment foo would create and edit config/credentials/foo.yml.enc.
- If config.credentials.content_path or config.credentials.key_path was set, bin/rails credentials:edit could not be used to edit the credentials. Editing credentials required using bin/rails encrypted:edit path/to/credentials --key path/to/key.
After:
- bin/rails credentials:edit will edit the credentials file that the app would load for the current RAILS_ENV.
- bin/rails credentials:edit respects config.credentials.content_path and config.credentials.key_path when set in config/application.rb or config/environments/#{Rails.env}.rb.
- bin/rails credentials:edit --environment foo will create and edit config/credentials/foo.yml.enc if config.credentials.content_path has not been set for the foo environment. Ultimately, it will edit the credentials file that the app would load for the foo environment.
Jonathan Hefner
Add descriptions for non-Rake commands when running rails -h.

Petrik de Heus
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
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.

Sam Ruby
