Send email with attachment in Ruby

Question

I need to send an email with an attachment via Ruby.

Been searching around but haven't found any simple script example to do this.

Closest I've found is ActionMailer but that seems to require a bunch of other scripts to to run. (NOTE: I am not using Ruby on Rails)

Answer 1

Have you checked out Mail? That is what the new ActionMailer API in Rails 3 is built upon.

"Mail is an internet library for Ruby that is designed to handle emails generation, parsing and sending in a simple, rubyesque manner."

Here comes a quick example from the docs:

require 'mail'

@mail = Mail.new
file_data = File.read('path/to/myfile.pdf')
@mail.attachments['myfile.pdf'] = { :mime_type => 'application/x-pdf',
                                    :content => file_data }

Update: Or even more simply:

@mail = Mail.new
@mail.add_file("/path/to/file.jpg")

@sergiovilar: Mail is a pure Ruby library. It does not depend on Rails. Hence it is a valid answer (even today, 6 years after the answer was posted). – Telecast

Sending Email or Email with any type of attachment has become more simple with the "mail" gem installation.

Step:1 Install "mail" gem

Step:2 In the ruby file maintain the syntax given below:

require 'mail'
def mailsender
      Mail.defaults do
        delivery_method :smtp,{ address: "<smtp_address>",openssl_verify_mode: "none" }
      end

      Mail.deliver do
        from     'from_mail_id'
        to       'to_mail_id'
        subject  'subject_to_be_sent'
        # body     File.read('body.txt')
        body     'body.txt'
        add_file '<file_location>/Word Doc.docx'
        add_file '<file_location>/Word Doc.doc'
      end
end

Step:3 now Just call the method in the step definition.
