I'm trying to find some code to send an email with attachment in
ruby. I'm using the following code to send an email, but I would like
to send an PDF. Can someone please tell me what code i need to add to
include a file called "the_attachment.pdf"? Thanks, Dave

## send email
require 'net/smtp'

# set up the email addresses
user_from = "my_email@here.com"
user_to = "their_email@there.com"

the_email = "From: my_email@here.com\n" +
            "Subject: Email with attachment\n\n" +
            "See attached PDF.\n\n"

# handling exceptions
begin
  Net::SMTP.start('localhost') do |smtp|
    smtp.send_message(the_email, user_from, user_to)
  end

rescue Exception => e
  print "Exception occured: " + e
end

Hi,

I'm trying to find some code to send an email with attachment in

Two years ago I started to write my own mail library. Initially I
only thought of filtering mails. Soon I started to generate mails,
too. In the meantime I filtered about 100,000 mails and I generated
about 25,000.

If you like to have a look at it, please do something like:

  gem fetch --source http://bertram-scharpf.homelinux.com/bs_gems/ cropmail
  fetch http://bertram-scharpf.homelinux.com/bs_gems/cropmail-1.6.gem

It isn't documented very well because nobody uses it but me, but
it is thoroughly tested and it is very easy to use.

Below I will cite some sample code how I generate a mail.

I would be pleased if you like it. In case you don't I wish you
good luck anyway.

Bertram

I use this:

require 'rubygems'
require 'action_mailer'
require 'mime/types'

ActionMailer::Base.smtp_settings = { :address => '10.209.3.26', :domain => '3dlabs.com'}

class Mailer < ActionMailer::Base
  def message (title, body)
    from 'Dave Baldwin <dave.baldwin@3dlabs.com>'
    recipients 'dave.baldwin@3dlabs.com'
    subject title
    body body

    # Include all the pdf files in the PDF subdirectory as attachments.
    FileList['PDF/*.pdf'].each do |path|
      file = File.basename(path)
      mime_type = MIME::Types.of(file).first
      content_type = mime_type ? mime_type.content_type : 'application/binary'
      attachment (content_type) do |a|
        a.body = File.read(path)
        a.filename = file
        a.transfer_encoding = 'quoted-printable' if content_type =~ /^text\//
      end
    end
  end
end

Mailer.deliver_message('some title', 'the body message')

I don't think there is an easy way to do so with net/smtp, put
actionmailer can handle attacments, I believe.

[snip code example]

/usr/ports/mail/mutt-lite installed.

well, i know it's low-brow, but i've been doing it like this:

system("cat #{bodyfile} | mutt -s #{subjectstring} -a #{attachmentfile} #{recipient}")

keep in mind, this is on FreeBSD servers with mutt installed.

# cd /usr/ports/mail/mutt-lite && make install clean

also, if you call this from cron (who wouldn't) you'll need to put the full path of mutt in your system call, typically /usr/local/bin/mutt.

if there's a *ruby way* to do this, i'd love to know what it is. i always feel a little dirty doing it like this.

There is no easy way to play with this :frowning:

You could try SimpleMail (http://simplemail.rubyforge.org/doc/\) from
RubyForge.

rmail has it on its TODO for years :frowning:

Yet another are where Ruby is lacking compared to other languages...

Here's updated code using sendmail and Dir.glob instead of FileList:

require 'rubygems'
require 'action_mailer'
require 'mime/types'

ActionMailer::Base.delivery_method = :sendmail
ActionMailer::Base.default_content_type = "text/plain"

class Mailer < ActionMailer::Base
  def message (from, to, title, body, attachments)
    from from
    recipients to
    subject title
    body body

    Dir.glob(attachments).each do |path|
      file = File.basename(path)
      mime_type = MIME::Types.of(file).first
      content_type = mime_type ? mime_type.content_type :
'application/binary'
      attachment (content_type) do |a|
        a.body = File.read(path)
        a.filename = file
        a.transfer_encoding = 'quoted-printable' if content_type =~
/^text\//
      end
    end
  end
end

Mailer.deliver_message 'Christopher Pickslay <from@somedomain.com>',
   'to@somedomain.com',
   'Some reports',
   "See attached tab-delimited reports\n\n",
   '/tmp/reports/*.txt'
