所以，我们刚刚在 Ruby 1.8.7 企业版的基础上将我们的项目升级到 Rails 3.0.17（请不要问为什么这个特定版本，只是这样）。

我有方法可以生成 CSV 数据并通过电子邮件将其作为文件发送。

# contact_mailer.rb
def send_payments_report
  attachments["report.csv"] = {
    :content => Payment.generate_csv_report,
    :mime_type => "text/csv"
  }

  mail(
    :from => "from@example.com",
    :subject => "Payments report",
    :to => "to@example.com"
  )   
end

这是它返回的内容：

=> #<Mail::Message:2231891440, Multipart: true, Headers: <Date: Wed, 19 Dec 2012 11:48:05 +0200>, <From: from@example.com>, <To: to@example.com>, <Message-ID: <50d18d555dcdc_2269838ab93812784@artem.local.mail>>, <Subject: Payments report>, <Mime-Version: 1.0>, <Content-Type: multipart/mixed; >, <Content-Transfer-Encoding: 7bit>>

电子邮件本身显示为没有附件的纯文本：

我尝试附加现有文件，但显示方式相同。它在 Rails 2.3.9 上完美运行。有人可以帮忙吗？

【解决方案1】：

我似乎已经解决了这个问题。这里我如何调用mail 方法：

mail(
  :from => "from@example.com",
  :subject => "Payments report",
  :to => "to@example.com"
) do |format|
    format.text {render :text => ""}
end
