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:

Answer 1

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
