Question

UP 04/08/2015：实际上是否可以同时使用.deliver_later和proc？

我的问题：

我的电子邮件没有执行生成TO字段的过程，因此在postfix上发送错误的电子邮件

后缀日志

控制器

...
if Rails.env.production? # Using :sendmail as delivery method
  MailingListsMailer.action(@mail).deliver_later
else # Typically using :letter_opener or :file as delivery method
  MailingListsMailer.action(@mail).deliver_now
...

邮件程序

class MailingListsMailer < ActionMailer::Base
   def action(message)
    format_mail_params(message)
    mail(
      to: Proc.new {read_emails_file},
      ...
    )
   end

    private

    def read_emails_file
      File.read('emails.txt').split('\n')
    end
end

配置

config.action_mailer.delivery_method = :sendmail
  config.action_mailer.smtp_settings = {
    :address => "localhost",
    :domain => "myorg.fr"
  }
    config.action_mailer.default_url_options = { host: 'myorg.fr', protocol: 'https' }

中建议的过程

你可能根本不需要Proc包装器，试试这个：

def action(message)
    format_mail_params(message)
    mail(
        to: read_emails_file,
        ...
    )
end

要调试它，请执行以下操作：

def action(message)
    format_mail_params(message)

    puts "*"*50
    emails = read_emails_file
    puts emails
    puts "*"*50

    mail(
        to: emails,
        ...
    )
end

然后检查服务器日志以查找类似于以下内容的消息：

*******************************************************************
[...]
*******************************************************************

迭代电子邮件

因为您不想透露所有人的电子邮件，并避免垃圾邮件检测，您可能想要迭代电子邮件数组：

def action(message)
  format_mail_params(message)

  read_emails_file.each do |email|
    mail(
        to: email,
        ...
    )
  end
end

Action Mailer不执行Proc以生成TO字段
