即使没有错误，Actionmailer 也不发送电子邮件

Question

我的系统上设置了几个不同的邮件程序。一个工作正常，另一个没有错误，但不发送电子邮件。

有效的邮件程序如下所示：

class UserMailer < ActionMailer::Base
  default from: "info@footballpoolmania.com"

  # Subject can be set in your I18n file at config/locales/en.yml
  # with the following lookup:
  #
  #   en.user_mailer.password_reset.subject
  #
  def password_reset(user)
    @user = user
    mail to: user.email, subject: "Password Reset"
  end

  def confirm_registration(user)
    @user = user
    mail to: user.email, subject: "Confirm Registration"
  end
end

在发送密码重置电子邮件时，我在日志中收到以下内容：

To reset your password, click the URL below.

http://localhost:3000/password_resets/c851e80faeb3612c654c512857cfb29afc6a4665/edit

If you did not request your password to be reset, just ignore this email and 
your password will continue to stay the same.

此外，消息的视图被定义为 password_reset.text.erb，位于 app/views/user_mailer 中，如下所示：

To reset your password, click the URL below.

<%= edit_password_reset_url(@user.password_reset_token) %>

If you did not request your password to be reset, just ignore this email and 
your password will continue to stay the same.

不起作用的邮件程序如下所示：

class PoolMailer < ActionMailer::Base
  default from: "info@footballpoolmania.com"

  def send_pool_message(pool, subject, msg, allMembers)
    @pool = pool
    @msg = msg
    email_list = Array.new
    @pool.users.each do |user|
      if allMembers
        entries = Entry.where(user_id: user.id)
      else
        entries = Entry.where(pool_id: pool.id, user_id: user.id, survivorStatusIn:true)
      end
      if entries.any?
        email_list << "#{user.name} <#{user.email}>"
      end
    end
    subject_text = pool.name + ": " + subject
    if mail to: email_list, subject: subject_text
      puts "Successfully sent email"
      return false
    else
      puts "Couldn't send email"
      return true
    end
  end
end

日志如下所示：

这封电子邮件的视图名为 send_pool_message.text.erb，位于 app/views/pool_mailer 中，如下所示：

<%= @msg %>

This is an automated email sent by the pool administer.  Do not reply to this
email.

第一个邮寄者正确地发送电子邮件并记录它。第二个邮件程序既不发送电子邮件也不记录电子邮件。我不确定在哪里可以解决问题，因为我收到的任何错误消息绝对为零。

任何帮助我指出正确的方向来解决这个问题将不胜感激。

Answer 1

您需要调用 .deliver 到您的邮件功能

PoolMailer.send_pool_message(...).deliver

否则它只会生成电子邮件而不发送它
