Rails - ActionMailer有时会在电子邮件内容前显示附件？

Question

我怎样才能使这样的ActionMailer始终显示在邮件的底部附件： HTML，TXT，附件....

问题是这里的附件是一个文本文件：

----==_mimepart_4d8f976d6359a_4f0d15a519e35138763f4 
Date: Sun, 27 Mar 2011 13:00:45 -0700 
Mime-Version: 1.0 
Content-Type: text/plain; 
charset=UTF-8 
Content-Transfer-Encoding: base64 
Content-Disposition: attachment; 
filename=x00_129999.olk14message 
Content-ID: <[email protected]> 

由于

Answer 1

我有同样的问题，在我的情况下，解决方案是交换附件和邮件行。首先附上，然后致电邮件。

的Rails 3

WRONG

def pdf_email(email, subject, pdfname, pdfpath) 
    mail(:to => email, :subject => subject) 
    attachments[pdfname] = File.read(pdfpath) 
end 

GOOD

def pdf_email(email, subject, pdfname, pdfpath) 
    attachments[pdfname] = File.read(pdfpath) 
    mail(:to => email, :subject => subject) 
end 

Answer 2

这是铁路2.3代码（可能是在Rails3中略有不同）

附件之前只是移动你的文字部分

recipients [email protected] 
from  [email protected] 
subject "some subject" 
content_type "multipart/mixed" 

part "text/plain" do |p| 
    p.body = render_message 'my_message' #this is template file 
end 

attachment "application/octet-stream" do |a| 
    a.body = File.read("some_file.jpg") 
    a.filename = 'name.jpg' 
end 

Answer 3

我知道已经有一个公认的答案，但切换的attachments[]顺序和mail()没有为我解决它。我的情况有所不同的是，我试图添加文本文件附件（.txt）

对我而言，适用于邮件程序的默认设置为content_type和parts_order。

MyMailer < ActionMailer::Base 

    default :from => "Awesome App <[email protected]>", 
      :content_type => 'multipart/alternative', 
      :parts_order => [ "text/html", "text/enriched", "text/plain", "application/pdf" ] 

    def pdf_email(email, subject, pdfname, pdfpath) 
     attachments[pdfname] = File.read(pdfpath) 
     mail(:to => email, :subject => subject) 
    end 

    def txt_email(email, subject, filename, filebody) 
     attachments[filename] = filebody 
     mail(:to => email, :subject => subject) 
    end 
end 

如果您要发送一封电子邮件中Rails 3中使用纯文本文件（.txt），试图将:content_type和parts_order你的默认设置，从而文本文件不会出现在您的电子邮件消息上方。
