This Week in Rails - August 25

Posted by Wojtek

Hi, Wojtek here. Let’s explore last 2 week’s changes in the Rails codebase.

Rails Versions, have been released
Just after the previous security releases, but with fixed file permissions.

MRSK renamed to Kamal
Due to a trademark claim, the project was renamed to Kamal.

Add after_discard method to Active Job
It lets job authors to define a block which will be run when a job is about to be discarded.

Ensure response.parsed_body support for pattern matching
Both Nokogiri and Minitest supports Ruby’s Pattern matching. By parsing the JSON contents of response.parsed_body with ActiveSupport::HashWithIndifferentAccess, it’s now pattern-matching compatible and can be used with Minitest’s new assert_pattern method.

Add support for Playwright as a driver for system tests
Playwright is getting popularity as a new browser automation tool. There is a community-maintained Ruby client and Capybara driver as well.

Generate config.autoload_lib for new Rails 7.1 apps
New 7.1 applications will autoload from lib directory out of the box. The new line in config/application.rb contains: config.autoload_lib(ignore: %w(assets tasks)).

Allow redefining to_param delimiter using param_delimiter
Adds ActiveModel::Conversion.param_delimiter to configure delimiter being used in to_param method.

Deprecate read_attribute(:id) returning the primary key
Starting in Rails 7.2, read_attribute(:id) will return the value of the id column, regardless of the model’s primary key. To retrieve the value of the primary key, one can use #id instead. read_attribute(:id) for composite primary key models will now return the value of the id column.

Use alias_attribute to provide id_value alias for id attribute
As the follow up to the above, added ActiveRecord::Base#id_value alias to access the raw value of a record’s id column. This alias is only provided for models that declare an :id column.

Sort mailers on the mailer preview page alphabetically

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.

Fix host display when X_FORWARDED_HOST authorized
Fix HostAuthorization potentially displaying the value of the X_FORWARDED_HOST header when the HTTP_HOST header is being blocked.

You can view the whole list of changes here. We had 35 contributors to the Rails codebase this past week!

Until next time!
