ruby-on-rails – 使用Delayed_Job发送电子邮件

我是Delayed_Job的新手,所以请原谅新手的错误.

这是包含send_reminder_emails方法的模型.它们完全没有.delay(run_at：self.mail_date)位,所??以至少我知道它有用了：

class Reminder < ActiveRecord::Base
  belongs_to :user
  before_save :create_mail_date
  after_save :send_reminder_emails
  extend FriendlyId
  friendly_id :name,use: [:slugged,:finders]

  def create_mail_date
    @schedule = IceCube::Schedule.new(self.date)
    case self.repeating
    when "Weekly"
        @schedule.add_recurrence_rule(
            IceCube::Rule.weekly
        )
    when "Monthly"
        @schedule.add_recurrence_rule(
            IceCube::Rule.monthly.day_of_month(self.date.mon)
        )
    when "Yearly"
        @schedule.add_recurrence_rule(
            IceCube::Rule.yearly.day_of_year(self.date.yday)
        )
    end
    if self.repeating
        self.date = @schedule.next_occurrence(Time.now)
    end
    self.mail_date = self.date - 7.days
  end

  private

  def send_reminder_emails
      if self.reminder
         ReminderMailer.delay(run_at: self.mail_date).reminder_send(self.user,self).deliver_now
         self.create_mail_date
     end
  end
  handle_asynchronously :send_reminder_emails

end

对计划的引用是通过Ice_Cube gem进行的,并且所有日期内容都已通过我的控制台进行测试并且正在运行.这是我的reminder_mailer.rb：

class ReminderMailer < ApplicationMailer
  default from: "man@manlyartofbbq.com"

  def reminder_send(user,reminder)
    @user = user
    @reminder = reminder

    mail(to: user.email,subject: "Reminder! #{reminder.name} is fast approaching!")
  end
end

我从他们的Rails 4自述文件中逐步安装了Delayed_Job.任何有助于让这封邮件的延迟部分解决的帮助表示赞赏！
