Ruby on Rails:使用iCalendar为事件创建电子邮件.谷歌不承认它

也许它不是谷歌做的东西了!我有以下代码.

mail(from: @process_action.finance_case.case_owner.user.email, to: @process_action.finance_case.case_owner.user.email, subject: "Appointment") do |format|
   format.ics {
   ical = Icalendar::Calendar.new
   e = Icalendar::Event.new
   e.start = DateTime.now.utc
   e.start.icalendar_tzid="UTC" # set timezone as "UTC"
   e.end = (DateTime.now + 1.day).utc
   e.end.icalendar_tzid="UTC"
   e.organizer "any_email@example.com"
   e.uid "MeetingRequest#{unique_value}"
   e.summary "Scrum Meeting"
   ical.add_event(e)
   ical.publish
   ical.to_ical
   render :text => ical.to_ical
  }
end

尝试将内容类型设置为文本/日历以及其他一些randon更改以查看是否有帮助.有人建议将'方法'设置为REQUEST以供谷歌识别但不确定如何或在何处.

我们将非常感激地收到任何帮助/指示.或者即使它可以在Outlook中工作,因为这是客户端使用的.

更新:上面不清楚,但电子邮件正在递送.其谷歌未能将其视为活动邀请.
