noname attachment in my gmail inbox

While using Rails ActionMailer with Multipart Emails I created both:

approve_trade_email.html.erb

AND

approve_trade_email.text.erb

I do receive a well HTML formatted email in my Mail client (Mac OSX) but when checking my Gmail account for the same email I got an empty body with a noname attachement with the multiparts inside?

Help?

Why do I get this in Gmail?

thx

Joel

HERE THE NONAME ATTACHEMENT IN GMAIL:

Solution

  • I got the same problem and found the solution:

    It's a bug in the old ActionMailer API of Rails 3, which does not include the multipart boundary definition in mail header.

    see: https://github.com/rails/rails/pull/3090

    You just have to use the new API (using the mail method)

    class UserMailer < ActionMailer::Base
  default :from => "[email protected]"

  def welcome_email(user)
    @user = user
    @url  = "http://example.com/login"
    mail(:to => user.email, :subject => "Welcome to My Awesome Site")
  end
end
