Rails 3邮件程序不起作用，也没有记录任何错误 [英] Rails 3 mailer not working and not logging any errors

问题描述

我尝试了各种配置，但仍然无法在Rails开发环境中发送电子邮件。

I have tried all kinds of configurations but still I can't send an email in my development environment from rails.

我安装了mailutils来从命令中尝试行并成功了，我收到了电子邮件（当然是垃圾邮件）：echo test |邮件-s主题[e-mail]

I installed mailutils to try this from the command line and it worked, I received the email (in spam of course): echo test | mail -s Subject [e-mail]

这是我的配置：

# Don't care if the mailer can't send
config.action_mailer.raise_delivery_errors = true # still no logs about emails

config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true # I can't believe I have to add this option. Does it even exist? I found it on google.
config.action_mailer.smtp_settings = {
  :enable_starttls_auto => true,
  :address => "smtp.gmail.com",
  :port => 587,
  :domain => "gmail.com",
  :authentication => :login,
  :user_name => "[e-mail]",
  :password => "abc123",
}

这是邮件中的代码：

class UserMailer < ActionMailer::Base
  default :from => "root@ubuntu"

  def test_email
    Rails.logger.debug 'test_email'
    mail(:to => '[e-mail]', :subject => "testing rails")
  end
end

控制器：

class PagesController < ApplicationController
  def home
    UserMailer.test_email
  end
end

development.log：

development.log:

我也尝试过使用控制台：

I also tried using the console:

root@ubuntu:/srv/www/myapp# rails c
Loading development environment (Rails 3.2.1)
irb(main):001:0> UserMailer.test_email
=> #<Mail::Message:32110400, Multipart: false, Headers: <To: [e-mail]>, <Subject: testing rails>, <Mime-Version: 1.0>, <Content-Type: text/html>>

推荐答案

  UserMailer.test_email

只需创建 Mail :: Message 宾语。要实际发送电子邮件，您需要

Just creates a Mail::Message object. To actually send an email you need to do

  UserMailer.test_email.deliver

（或从rails 4.2开始 deliver_now / deliver_later ）

(or starting with rails 4.2 deliver_now / deliver_later)
