Rails4 ActiveSupport::TimeWithZone as_jsonの仕様変更

Last updated at Posted at 2013-08-20

Rails3からRails4にアップデートする時の細かい変更ポイントです。

ActiveSupport::TimeWithZoneのas_json内で xmlschema -> xmlschema(3)に変更になっています。

time_with_zone.rb
module ActiveSupport
  class TimeWithZone
    def as_json(options = nil)
      if ActiveSupport::JSON::Encoding.use_standard_json_time_format
        xmlschema(3)
      else
        %(#{time.strftime("%Y/%m/%d %H:%M:%S")} #{formatted_offset(false)})
      end
    end
  end  
end


Rails3 2013-08-02T09:22:34Z
Rails4 2013-08-02T09:22:34.060Z
という違いになります。
