Ruby On Rails 3 アプリケーションの日付変換で奇妙な問題が発生しましたが、その理由が本当にわかりません...

これが私のen.ymlとfr.ymlです：

fr:
  date:
    formats:
      default: "%d/%m/%Y"
      short: "%e %b"
      long: "%e %B %Y" 
  time:
    formats:
      default: "%d %B %Y %H:%M:%S"
      short: "%d %b %H:%M"
      long: "%A %d %B %Y %H:%M"
    am: 'am'
    pm: 'pm'



en:
  date:
    formats:
      default: "%Y-%m-%d"
      long: "%B %d, %Y"
      short: "%b %d"
  time:
    am: am
    formats:
      default: ! '%a, %d %b %Y %H:%M:%S %z'
      long: ! '%B %d, %Y %H:%M'
      short: ! '%d %b %H:%M'
    pm: pm

これは特定のビューに固有のものではありませんが、たとえば私のビューの 1 つでは:

<td><%=l job_application.created_at, :format => :default %></td>

私はそれらの奇妙な出力を取得します:

With locale = :en
=> t, 30 o 2012 18:09:33 +0000

With locale = :fr
=> 30 o 2012 18:09:33

これらの間違った「フォーマット」はどこから来たのですか?

Rails 3.2.8 (Postgresql/gem pg を使用) を使用しており、日付を除いて I18n に関連するすべてが正常に動作します。

助けてくれてありがとう！

I think I've finally figured this out, sorry for taking so long.

The Rails l helper just calls I18n.localize. If you trace through the I18n.localize code, you'll end up here:

format = format.to_s.gsub(/%[aAbBp]/) do |match|
  case match
  when '%a' then I18n.t(:"date.abbr_day_names",                  :locale => locale, :format => format)[object.wday]
  when '%A' then I18n.t(:"date.day_names",                       :locale => locale, :format => format)[object.wday]
  when '%b' then I18n.t(:"date.abbr_month_names",                :locale => locale, :format => format)[object.mon]
  when '%B' then I18n.t(:"date.month_names",                     :locale => locale, :format => format)[object.mon]
  when '%p' then I18n.t(:"time.#{object.hour < 12 ? :am : :pm}", :locale => locale, :format => format) if object.respond_to? :hour
  end
end

So the localize helper doesn't use strftime for the "stringy" parts of the date/time, it tries to do it by itself. Add the translations (as arrays in your YAML) for the month and day names as above and your localized dates and times should start working.

If you don't have those translation arrays in your YAML, then I18n.t(:"date.abbr_month_names") will give you strings like this:

"translation missing: en.date.abbr_month_names"

and then I18n.localize will end up doing silly things like this:

"translation missing: en.date.abbr_month_names"[10]

That will use String#[] instead of the expected Array#[] and you end up with random looking single character month and day names.

は DateTime であるためcreated_at、レールは format time(not date) を使用します。

https://github.com/svenfuchs/rails-i18n/blob/master/rails/locale/en.yml#L195

time:
  am: am
  formats:
    default: ! '%a, %d %b %Y %H:%M:%S %z'
