form_forのf.date_select実装時のエラー undefined method `map' for "translation missing: ja.date.order":String

Last updated at Posted at 2019-10-04

undefined method `map' for "translation missing: ja.date.order":String

form_forにてf.date_selectを実装しようとした時のエラー

rails 5.2.3
ruby 2.5

birthdayカラムはdate型

調べるとrails4で良く起きているらしい。rails5なのに。。。。

とりあえず。。。

解決方法

config>locales>ja.ymlを作成

ja.yml
ja:
  date:
    formats:
      default: "%Y/%m/%d"
      short: "%m/%d"
      long: "%Y年%m月%d日(%a)"

    day_names: [日曜日, 月曜日, 火曜日, 水曜日, 木曜日, 金曜日, 土曜日]
    abbr_day_names: [, , , , , , ]

    month_names: [~, 1月, 2月, 3月, 4月, 5月, 6月, 7月, 8月, 9月, 10月, 11月, 12月]
    abbr_month_names: [~, 1月, 2月, 3月, 4月, 5月, 6月, 7月, 8月, 9月, 10月, 11月, 12月]

    order:
      - :year
      - :month
      - :day

  time:
    formats:
      default: "%Y/%m/%d %H:%M:%S"
      short: "%y/%m/%d %H:%M"
      long: "%Y年%m月%d日(%a) %H時%M分%S秒 %Z"
    am: "午前"
    pm: "午後"

を追記とりあえず解決
