ActionMailer有时不发送？ [英] ActionMailer sometimes not sending?

问题描述

我遇到一个问题，即ActionMailer有时不发送电子邮件。它是可复制的，并且在某些时候会影响某些人，尽管导致它是一个谜。

尽管 config.action_mailer，它却默默地失败了。

它进入mail（）例程，声称已渲染了模板：

 渲染的notifier / notify_comment.html.erb（0.9毫秒）
  

，然后跳过传递内容，移至下一个。下一个呈现&交付没问题。传递电子邮件后，它们还会打印到控制台上，因此我可以看到它。每封电子邮件的内容都是相同的，只是收件人是不同的。

我不明白为什么这是断断续续的。

我该如何调试它？

解决方案

每个邮件发件人实例只能发送1封电子邮件。 p>

邮件中是否有类似这样的代码？

  @ subscribers.each做| s | 
 mail（
：to => s.email，
：subject => Foo Foo，
：from => [e-mail]， 
：template_name =>'template_name'
）。交付
结束
  

这似乎不起作用。遍历邮件程序外部的订户，并调用一次：

在控制器或模型中：

  @ subscribers.each做| s | 
 Notifier.send_to_subscriber（s，@comment）
结束
  

这是我的有Rails 3.2.2的经验。 FWIW，我认为发生的事情是邮件对象超出范围。

这种方法可能很慢，因此请确保在单独的线程中发送电子邮件。

参考和想法：如何使用SendGrid发送多封电子邮件？

I have a problem where ActionMailer sometimes doesn't send emails. It is reproducible and affects certain people at certain times, although what is causing it is a mystery.

It fails silently, although config.action_mailer.raise_delivery_errors = true is set.

It enters the mail() routine, claims it has rendered the template:

Rendered notifier/notify_comment.html.erb (0.9ms)

And then skips the delivery and moves onto the next one. The next one is rendered & delivered no problem. When emails are delivered, they are also printed to the console, so I can see it. The content of every email is the same, only the recipient is different.

I cannot understand why this would be intermittent.

How can I go about debugging this?

解决方案

Each instance of the mailer can only send 1 email.

Do you have code that looks like this inside of the mailer?

@subscribers.each do |s|
  mail(
    :to => s.email,
    :subject => "Foo Foo",
    :from => "[e-mail]", 
    :template_name => 'template_name'
  ).deliver
end

This doesn't seem to work. Iterate over the subscribers outside of the mailer, and call it once:

In a controller or model:

@subscribers.each do |s|
  Notifier.send_to_subscriber(s, @comment)
end

This was my experience in Rails 3.2.2. FWIW, I think what happens is that the mail object falls out of scope.

This approach may be slow, so be sure to send emails in a separate thread.
