Build Status Gem Version

RuboCop configuration which has the same code style checking as official Ruby on Rails.

Official RoR RuboCop Configuration


Add this line to your application’s Gemfile:

“by gem “rubocop-rails_config”


Add this line to your application’s .rubocop.yml, or just run rails generate rubocop_rails_config:install:

“l inherit_gem: rubocop-rails_config: - config/rails.yml


If you’d like to customize the rubocop setting, you can override it.

For example, if you want to change TargetRubyVersion, you can do it like:

“l inherit_gem: rubocop-rails_config: - config/rails.yml

AllCops: TargetRubyVersion: 2.6

This overrides config/rails.yml setting with TargetRubyVersion: 2.6.
