rails config ymlを読み込み

https://swaac.tamouse.org/swaac/2015/01/20/rails-4-dot-2-config-for/

rails 3

APP_CONFIG = YAML.load_file("#{::Rails.root}/config/app_config.yml")[::Rails.env]

after rails 4.2

Rails.application.config_forを利用

APP_CONFIG = Rails.application.config_for(:app_config)

１つのymlでなく環境ことに分けたいときに

でも、まあ使わないかな

# Gemfile
gem 'config'

# initial
rails g config:install
