  • Update rails new --minimal option

    Extend the --minimal flag to exclude recently added features: skip_brakeman, skip_ci, skip_docker, skip_kamal, skip_rubocop, skip_solid and skip_thruster.

  • Use secret_key_base from ENV or credentials when present locally.

    When ENV or Rails.application.credentials.secret_key_base is set for test or development, it is used for the Rails.config.secret_key_base, instead of generating a tmp/local_secret.txt file.

  • Add Kamal support for devcontainers

    Previously generated devcontainer could not use docker and therefore Kamal.

    Joé Dupuis

Rails 8.0.0.beta1 (September 26, 2024) ↑

  • Exit rails g with code 1 if generator could not be found.

    Previously rails g returned 0, which would make it harder to catch typos in scripts calling rails g.

    Christopher Özbek

  • Remove require_* statements from application.css to align with the transition from Sprockets to Propshaft.

    With Propshaft as the default asset pipeline in Rails 8, the require_tree and require_self clauses in application.css are no longer necessary, as they were specific to Sprockets. Additionally, the comment has been updated to clarify that CSS precedence now follows standard cascading order without automatic prioritization by the asset pipeline.

    Eduardo Alencar

  • Do not include redis by default in generated Dev Containers.

    Now that applications use the Solid Queue and Solid Cache gems by default, we do not need to include redis in the Dev Container. We will only include redis if --skip-solid is used when generating an app that uses Active Job or Action Cable.

    When generating a Dev Container for an existing app, we will not include redis if either of the solid gems are in use.

    Andrew Novoselac

  • Use Solid Cable as the default Action Cable adapter in production, configured as a separate queue database in config/database.yml. It keeps messages in a table and continuously polls for updates. This makes it possible to drop the common dependency on Redis, if it isn't needed for any other purpose. Despite polling, the performance of Solid Cable is comparable to Redis in most situations. And in all circumstances, it makes it easier to deploy Rails when Redis is no longer a required dependency for Action Cable functionality.

    DHH

  • Use Solid Queue as the default Active Job backend in production, configured as a separate queue database in config/database.yml. In a single-server deployment, it'll run as a Puma plugin. This is configured in config/deploy.yml and can easily be changed to use a dedicated jobs machine.

    DHH

  • Use Solid Cache as the default Rails.cache backend in production, configured as a separate cache database in config/database.yml.

    DHH

  • Add Rails::Rack::SilenceRequest middleware and use it via config.silence_healthcheck_path = path to silence requests to “/up”. This prevents the Kamal-required health checks from clogging up the production logs.

    DHH

  • Introduce mariadb-mysql and mariadb-trilogy database options for rails new

    When used with the --devcontainer flag, these options will use mariadb as the database for the Dev Container. The original mysql and trilogy options will use mysql. Users who are not generating a Dev Container do not need to use the new options.

    Andrew Novoselac

  • Deprecate ::STATS_DIRECTORIES.

    The global constant STATS_DIRECTORIES has been deprecated in favor of Rails::CodeStatistics.register_directory.

    Add extra directories with Rails::CodeStatistics.register_directory(label, path):

    require "rails/code_statistics"
Rails::CodeStatistics.register_directory('My Directory', 'path/to/dir')

    Petrik de Heus

  • Enable query log tags by default on development env

    This can be used to trace troublesome SQL statements back to the application code that generated these statements. It is also useful when using multiple databases because the query logs can identify which database is being used.

    Matheus Richard

  • Defer route drawing to the first request, or when url_helpers are called

    Executes the first routes reload in middleware, or when a route set's url_helpers receives a route call / asked if it responds to a route. Previously, this was executed unconditionally on boot, which can slow down boot time unnecessarily for larger apps with lots of routes.

    Environments like production that have config.eager_load = true will continue to eagerly load routes on boot.

    Gannon McGibbon

  • Generate form helpers to use textarea* methods instead of text_area* methods

    Sean Doyle

  • Add authentication generator to give a basic start to an authentication system using database-tracked sessions and password reset.

    Generate with...

    bin/rails generate authentication

    Generated files:

    app/models/current.rb
app/models/user.rb
app/models/session.rb
app/controllers/sessions_controller.rb
app/controllers/passwords_controller.rb
app/mailers/passwords_mailer.rb
app/views/sessions/new.html.erb
app/views/passwords/new.html.erb
app/views/passwords/edit.html.erb
app/views/passwords_mailer/reset.html.erb
app/views/passwords_mailer/reset.text.erb
db/migrate/xxxxxxx_create_users.rb
db/migrate/xxxxxxx_create_sessions.rb
test/mailers/previews/passwords_mailer_preview.rb

    DHH

  • Add not-null type modifier to migration attributes.

    Generating with...

    bin/rails generate migration CreateUsers email_address:string!:uniq password_digest:string!

    Produces:

    class CreateUsers < ActiveRecord::Migration[8.0]
  def change
    create_table :users do |t|
      t.string :email_address, null: false
      t.string :password_digest, null: false

      t.timestamps
    end
    add_index :users, :email_address, unique: true
  end
end

    DHH

  • Add a script folder to applications, and a scripts generator.

    The new script folder is meant to hold one-off or general purpose scripts, such as data migration scripts, cleanup scripts, etc.

    A new script generator allows you to create such scripts:

    bin/rails generate script my_script
bin/rails generate script data/backfill

    You can run the generated script using:

    bundle exec ruby script/my_script.rb
bundle exec ruby script/data/backfill.rb

    Jerome Dalbert, Haroon Ahmed

  • Deprecate bin/rake stats in favor of bin/rails stats.

    Juan Vásquez

  • Add internal page /rails/info/notes, that displays the same information as bin/rails notes.

    Deepak Mahakale

  • Add Rubocop and GitHub Actions to plugin generator. This can be skipped using –skip-rubocop and –skip-ci.

    Chris Oliver

  • Use Kamal for deployment by default, which includes generating a Rails-specific config/deploy.yml. This can be skipped using --skip-kamal. See more: kamal-deploy.org/
