当我创建一个新的管理员用户时，有三个翻译对象：
Admin.last.translations.map(&:locale) # => [:ru, :uz, :uz]
为什么区域设置重复？
示例：
admin.position_uz = 'CTO'
admin.position_ru = 'CTO'
admin.save!
admin.translations.count = 3
admin.translations.first.position = 'CTO'
admin.translations.second.position = 'Another value or empty'
admin.translations.third.position = 'CTO'
每次将区域设置设置为uz时，都会显示第二个变体。
管理员翻译看起来像
[
#<Admin::Translation id: 1, admin_id: 2, locale: "ru", position: "CTO", created_at: "2019-01-16 06:24:17", updated_at: "2019-01-16 06:30:31">,
#<Admin::Translation id: 2, admin_id: 2, locale: "uz", position: "Board Member", created_at: "2015-07-26 20:42:18", updated_at: "2015-07-26 20:42:18">,
#<Admin::Translation id: 3, admin_id: 2, locale: "uz", position: "CS manager", created_at: "2019-01-16 06:24:17", updated_at: "2019-01-16 07:09:21">
