【Rails】I18nの定義存在チェック

More than 1 year has passed since last update.

指定したkeyがI18n定義済みか確認したい

I18n.exists?(#{key}) で確認できます。

config/locales/ja.yml
ja:
  users:
    index:
      title: ユーザ一覧
I18n.exists?('users.index.title')
=> true # 定義済みなので true

I18n.exists?('users.show.title')
=> false # そんな定義は無いので false
