Rails - ActionMailer sometimes shows attachments before the email content?

Question

How can I make it so ActionMailer always shows attachments at the bottom of the message: HTML, TXT, Attachments....

Problem is the attachment here is a text file:

----==_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: <4d8f976d49c72_4f0d15a519e351387611f@railgun64.53331.mail>

Thanks

Answer 1

I had the same problem, and in my case the solution was to swap the attachment and mail lines. First attach, then call mail.

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

I know there is already an accepted answer, but switching the order of attachments[] and mail() didn't solve it for me. What is different about my situation is that I was trying to attach a text file attachment (.txt)

What works for me is setting the content_type and parts_order defaults for the mailer.

MyMailer < ActionMailer::Base

    default :from => "Awesome App <support@example.com>",
            :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

If you are trying to send an email in Rails 3 with a plain text file (.txt), trying adding :content_type and parts_order to your defaults so that the text file does not appear above the message in your email.

Answer 3

this is rail 2.3 code (might be slightly different in rails3)

just move you text part before attachment

recipients  to@domain.com
from      me@domain.com
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
