Current status

• Targeted release: Fedora 27
• Last updated: 2017-06-06
• Last updated: 2017-06-06
• Tracker bug: #1458667

Detailed Description

The Ruby on Rails stack is evolving quickly and Fedora needs to keep pace with it. Therefore the whole Ruby on Rails stack should be updated from 5.0 in Fedora 26 to 5.1 (latest version) in Fedora 27. This will ensure that all the Ruby developers using Fedora have the latest and greatest RPM-packaged Ruby on Rails.

Benefit to Fedora

This update will keep Fedora up-to-date and will ensure that the current Ruby on Rails developers stay with us as they will get support for system-packaged Ruby on Rails of the latest version. Apart from that, update to Rails 5.1 will drop jQuery as a default dependency, brings Yarn, Webpack and Capybara integration. New Rails also newly support encrypted secrets, Parameterized Mailers and Virtual/generated column support(for MySQL and MariaDB). In addition update to Rails 5.1 contains hundreds of other fixes and improvements across all the frameworks.

Upgrade/compatibility impact

Web applications build above Ruby on Rails framework might need to be updated. Official upstream upgrade guide might come handy: http://guides.rubyonrails.org/upgrading_ruby_on_rails.html

How To Test

• No special hardware is needed.

To test Rails 5.1 from upstream

gem install rails -v 5.1.x
rails new app
cd app && rails s

• Go to http://127.0.0.1:3000/ and make sure you are running Rails 5.1.x

To test only Rails itself

dnf install rubygem-rails
rails new app
cd app && rails s

• Go to http://127.0.0.1:3000/ and make sure you are running Rails 5.1.x

To test the complete feature including generating a new Rails app using RPM

dnf install rubygem-{rails,byebug,coffee-rails,jbuilder,jquery-rails,listen,puma,sass-rails,spring,spring-watcher-listen,sqlite3,turbolinks,uglifier,web-console} nodejs
rails new app --skip-bundle && cd app
rails s

• Go to http://127.0.0.1:3000/ and make sure you are running Rails 5.1.x

User Experience

• New version of Ruby on Rails (5.1) available
• The most significant Rails 5.1 features:
  • Drop jQuery as a default dependency
  • Yarn, Webpack and Capybara integration
  • Encrypted secrets, Parameterized Mailers and Virtual/generated column support(for MySQL and MariaDB)

Dependencies

• There are several packages, which depends on Ruby on Rails framework. All need to be tested an updated:
• These needs to be surely updated:
  • (none)
• Following gems don't support Rails 5.1 right now and would be broken by the update:
  • (none)
• As Rails requires Ruby >= 2.2.2, the platform less than the version can not use Rails 5.1.

Contingency Plan

• Contingency mechanism: None needed. Rails stack won't be updated until all its dependencies are in Rawhide. After that, it will be a simple matter of updating the core packages (and their dependencies).
• Contingency deadline: N/A
• Blocks release? No
• Blocks product? No
