Question

I am not sure why the email that I send via ActionMailer with an attachment doesn’t show me the attachment instead the contents of the attachment is just shown / output into the email.

class MyMailer < ActionMailer::Base
  default :from => "[e-mail]"

  def test_email()
    attachments['testresult1.html'] = {
      :filename => 'testresult1.html',
      :body => File.read('C:\\testresult1.html')
    }

  mail(:to => '[e-mail]',
    :subject => 'Cool great message'
  )
  end
end

The output of the email looks like this

Date: Tue, 17 Apr 2012 14:11:52 +1000
Mime-Version: 1.0
Content-Type: text/html;
charset=UTF-8;
filename=testresult1.html
Content-Transfer-Encoding: 7bit
Content-Disposition: attachment;
filename=testresult1.html
filename: testresult1.html
Content-ID: <[e-mail]>

and then the whole contents of the HTML file/attachment.

I’d expect the HTML file to be attached to the email as it would be attached to a normal email and I should be able to double click on the attachment and open it in a browser.

Email Client = Microsoft Outlook
Connection = SMTP
Rails = 3.2.1
ActionMailer = 3.2.1
Mail = 2.4.4

Answer 1

You should try adding a body key to #mail.
