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

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 ",
            :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.
