如果没有延迟作业 gem 和相关的代码更改，电子邮件将通过我的应用程序正确处理。

按照在 github wiki 上找到的 gem 的常见问题指南，标题为“作业已从数据库中静默删除”，我执行了以下操作：

/config/initializers/delayed_job.rb

Delayed::Worker.destroy_failed_jobs = false

重新启动workers和rails服务器后，我再次尝试，但是当我将电子邮件设置为处理时，我仍然可以看到delayed_job行被添加，然后很快被删除。

正在从控制器调用电子邮件，如下所示：

PresentationMailer.delay.presentation_invitation(@presentation)

从 rails 控制台（预计，我还没有成功运行过作业）：

1.9.3p194 :001 > Delayed::Job.last
  Delayed::Backend::ActiveRecord::Job Load (0.5ms)  SELECT `delayed_jobs`.* FROM `delayed_jobs` ORDER BY `delayed_jobs`.`id` DESC LIMIT 1
 => nil

摘自/log/delayed_job.log

2013-08-06T16:30:54+1200: [Worker(delayed_job host:192.168.1.251 pid:26688)] Job Class#presentation_invitation (id=9) RUNNING
2013-08-06T16:30:54+1200: [Worker(delayed_job host:192.168.1.251 pid:26688)] Job Class#presentation_invitation (id=9) COMPLETED after 0.0081
2013-08-06T16:30:54+1200: [Worker(delayed_job host:192.168.1.251 pid:26688)] 1 jobs processed at 9.1940 j/s, 0 failed

这似乎表明没有错误被击中；但是没有发送邮件（通过wireshark确认，没有数据包发送到我的SMTP服务器）

/app/mailers/presentation_mailer.rb

class PresentationMailer < ActionMailer::Base
  helper :application
  default from: "alias@domain.test"
  def presentation_invitation(email)
    return false if email.sent
    contact = nil
    presentation = nil
    if email.emailable.class == PresentationAttendee
      contact = email.emailable.contact
      presentation = email.emailable.presentation
    else
      return false
    end
    ics = RiCal.Event do
      description "Presentation"
      dtstart DateTime.parse(presentation.date_time)
      dtend DateTime.parse((presentation.date_time + 30*60).to_s) # (90 minutes length)
      location presentation.presentation_location.to_s
      add_attendee contact.email_address
      alarm do
        description "Presentation"
      end
    end
    attachments["calendar-reminder.ics"] = {mime_type: "text/calendar", content: ics.export}
    @email = email
    @contact = contact
    @presentation = presentation
    content_type = "multipart/mixed" # Required for background processing of mail to complete with attachment in tact
    mail to: "#{contact.first_name} #{contact.last_name} <#{contact.email_address}>", subject: email.email_content.subject if email.email_content
  end
end

关于如何进一步解决此问题的任何想法？

尝试这样做：

创建一个初始化程序并添加该行

require 'ri_cal'

现在试着让我知道它是怎么回事。
