Email attachments

Question

I want to be able to attach a file that I generate (on the fly, I dont want to save the file on my server) and send it out via email.

I have the text all done, but I'm lost on how to attach the file to the email using sendmail

Thank you

Answer 1

See http://railscasts.com/episodes/206-action-mailer-in-rails-3

def registration_confirmation(user)
  @user = user
  attachments["rails.png"] = File.read("#{Rails.root}/public/images/rails.png")
  mail(:to => "#{user.name} <#{user.email}>", :subject => "Registered")
end

Answer 2

You should be using Action Mailer that's built into Rails which supports sending emails with attachments.

For Rails 3.x - http://guides.rubyonrails.org/action_mailer_basics.html#sending-emails-with-attachments

For Rails 2.3.8+ - http://guides.rubyonrails.org/v2.3.8/action_mailer_basics.html#sending-multipart-emails-with-attachments
