Rails ActionMailer中的附件出现问题

Question

我正在使用以下代码（如《 Rails指南》中所述）：

def email(file, report_filename, report_type)
    attachments['image.jpg'] = File.read('/Users/admin/Desktop/Codica/fame_and_partners/website/maxresdefault.jpg')
    mail(
      to: 'some_email@gmail.com',
      subject: "Daily orders report #{Date.today.to_date} #{report_type}",
      layout: false
    )
  end

收到电子邮件时，我有一个名为noname的文件，其中附加了以下内容，而不是我的图像：

--
Content-Type: image/jpeg;
 charset=UTF-8;
 filename=image.jpg
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
 filename=image.jpg
Content-ID: <57a9a5c241e82_b9a3fd05c463be4522b9@MacBook-Pro-citrus.local.mail>

我正在使用Rails 3.2.2.22。 如何解决这个问题？

Answer 1

attachments.inline['photo.png'] = File.read('path/to/photo.png')

<%= image_tag attachments['photo.png'].url -%>
