Rails 3 / delayed_job-通缉：延迟邮件的基本示例 [英] Rails 3/delayed_job - Wanted: Basic example of delayed mail

问题描述

我一直在尝试找出如何使用带有rails 3的delay_job发送延迟的邮件。我已经尝试了几乎所有可以想到的可行组合-我可以让邮件在后台运行，我只是无法让它延迟发送到将来的时间。 db中的delay_jobs表清除了任务，日志显示已发送，delayed_job任务处理器选择了任务&说发送没有失败...但是邮件是：

I've been trying to figure out how to send delayed mail using delayed_job with rails 3. I've tried pretty much every combination of feasible possibilities I can think of - I can get the mail to run in the background, I just can't get it to delay the sending to a future time. The delayed_jobs table in the db clears the tasks, the log says 'sent', the delayed_job task processor picks up the task & says sent without failure...but the mail is either:

• 立即发送，或


• 如果我以后尝试发送邮件，就不会到达

。

如果有人能提供将来发送邮件的rails 3 delay_job的简单例子，我将非常感激。我确定很多人都会这样做，所以我怀疑我缺少明显的东西。我尝试过以下一种（无数）组合：

If anyone could offer a bare-bones example of a rails 3 delayed_job that sends mail in the future, I'd be really appreciative. I'm sure lotsa folks do this so I suspect I'm missing something obvious. One (of countless) combinations I've tried below:

delayed_job：2.1.2
滑轨：3.0.3
actionmailer：3.0.3

delayed_job: 2.1.2 rails: 3.0.3 actionmailer: 3.0.3

控制器：

class TestmailerController < ApplicationController
  def index
    Testmailer.delay.test_mail
  end

end

邮件程序：

class Testmailer < ActionMailer::Base
  def test_mail
    mail(:to => '([e-mail]', :from => '(removedforprivacy)@gmail.com', :subject => 'Testing Delayed Job', :content_type => 'text/plain').deliver
  end
  handle_asynchronously :test_mail, :run_at => Proc.new { 2.minutes.from_now }


end

config / environments / development.rb的相关邮件部分：

relevant mail part of config/environments/development.rb:

  # Don't care if the mailer can't send
  config.action_mailer.raise_delivery_errors = true

  # Print deprecation notices to the Rails logger
  config.active_support.deprecation = :log

  config.action_mailer.default_url_options = { :host => 'localhost:3000' }

  ActionMailer::Base.smtp_settings = {
    :address => "smtp.gmail.com",
    :port => 587,
    :domain => "gmail.com",
    :user_name => "(removedforprivacy)",
    :password => "(removedforprivacy)",
    :authentication => "plain",
    :enable_starttls_auto => true
  }

作业命令：

rake jobs:work

推荐答案

我同意andrea-我遇到了这个确切的问题，将本地开发数据库从sqlite切换到mysql之后，我可以运行类似的代码

I agree with andrea - I was having this exact problem, and after switching my local development database from sqlite to mysql, I can run code like

Emailer.delay({:run_at => 5.minutes.from_now}).welcome(@user)

，并在5分钟后发送电子邮件。请注意，您可能需要大于五分钟的延迟（以防时区怪异），以确保其正常工作。

and it sends the email 5 minutes later. Note that you might need a bigger delay than five minutes (in case of time zone weirdness) to be sure it is working.
