gem 'devise-i18n' 추가

Rails 국제화 API

각각 다른 환경 설정 가능

C:\Users\student\project\real_board\config\environments\development.rb

C:\Users\student\project\real_board\config\environments\production.rb

C:\Users\student\project\real_board\config\environments\test.rb

개발 실제 배포 환경

C:\Users\student\project\real_board\config\initializers

앱이 처음 켜졌을때 모두 load이고 수정하면 꼭 서버를 껐다 켜야한다

C:\Users\student\project\real_board\config\locales

우리가 주로 보는곳

.yml = yaml => xml을 쉽게 쓸 수 있는 문서

C:\Users\student\project\real_board\config\application.rb

여기있는 모든 파일들이 상속받고 가장 priority에 있는 파일, 모두 적용

2개 comment-out

config.time_zone = 'Central Time (US & Canada)'
변경
config.time_zone = 'Seoul'

config.i18n.default_locale = :de
변경
config.i18n.default_locale = :ko

수정 후

rails g devise:i18n:locale ko => C:\Users\student\project\real_board\config\locales\devise.views.ko.yml 생성
rails g devise:i18n:views => C:\Users\student\project\real_board\app\views\devise 생성
