在不重新排列排队系统的情况下，实现摘要电子邮件最优雅的方式是什么？ [英] What's the most elegant way to implement a digest email without reinventing a queueing system?

问题描述

我有我的交易电子邮件系统设置&默认情况下，当事件发生时，人们会收到电子邮件：

 类评论
 
 after_create：email_original_poster 
 
 def email_original_poster 
 UserMailer.delay.notify_author_of_comment self 
 end 
 
 end 
  

然而，我的用户的一大部分不喜欢每天或每周的摘要。

实现这个最干净最优雅的方式是什么？

已经有$ code> delayed_job 运行，但这并不真的像一个 delayed_job 工作，因为我排队需要的数据被执行而不是需要执行的操作。

...而不重新排列排队系统

我知道明显的解决方案是 queued_emails 的表，当然我可以这样做。我提出这个问题的原因是，这样做是重新排列排队系统。不仅在那里有很多排队系统，但是从Percona指出的这个很好的帖子指出，不要自己滚动：

您是否实施了摘要电子邮件，是否使用 delayed_job &你学到了什么？

解决方案

如果有人想要更好的方式做更多的细节，好的概述（第二个答案）：根据间隔使用电子邮件发送Ruby on Rails

I have my transactional email system setup & by default people get emails as events happen:

class Comment

  after_create :email_original_poster

  def email_original_poster
    UserMailer.delay.notify_author_of_comment self
  end

end

However instead of getting the email as-it-happens, a chunk of my users would prefer a daily or weekly digest.

What's the cleanest most elegant way to implement this?

I've already got delayed_job running but this doesn't really feel like a delayed_job job since I'm queueing data that needs to be acted on rather than actions that need to be executed.

...without reinventing a queueing system

I know that the obvious solution is table of queued_emails and of course I could do that. The reason I'm asking the question is that to do so is reinventing a queueing system. Not only are there lots of queuing systems out there but as this well worded post from Percona points out, it's a good idea not to roll your own:

http://www.engineyard.com/blog/2011/5-subtle-ways-youre-using-mysql-as-a-queue-and-why-itll-bite-you/

Have you implemented a digest email, did you use delayed_job & what did you learn?
