ruby - 电子邮件属性的未定义方法

问题描述

我正在尝试一次向多个收件人发送一堆单独的电子邮件。我打算这样做是用户将下载一个 Excel 电子表格并用一堆姓名和相应的电子邮件填写它，然后将该电子表格上传到应用程序。该应用程序创建填写了字段的客人名单对象，我想向客人名单中的每个人发送一封电子邮件。

客人名单的导入工作正常，但我似乎无法让我的邮件程序正常发送电子邮件。

更新

Mailer 现在发送的电子邮件数量与来宾列表中的人数相同，但所有电子邮件都发送到其中一个电子邮件地址。

邮件程序代码：

def guestlist_email()
 Guestlist.all.each { |guestlist| mail(to: guestlist.email) }
end

控制器代码：

def import
 Guestlist.import(params[:file])
 Guestlist.all.each do |guestlist|
  GuestMailer.with(guestlist: @guestlist).guestlist_email.deliver_now
 end
 redirect_to guestlists_url, notice: "Guest-list Successfully 
 Imported."
end

如果您需要更多代码，我将上传。

这是来自终端的日志。

解决方案

如果您将电子表格导入功能与电子邮件功能分开，它可能更具可读性。所以首先导入整个excel表。然后循环遍历表中的数据并一次发送一封邮件。

你的循环应该是这样的：

class SendWeeklySummary
  def run
    User.find_each do |user|
      UserMailer.with(user: user).weekly_summary.deliver_now
    end
  end
end
