Send email with attachments in Ruby

[loominator1970]

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 = "(e-mail address removed)"
user_to = "(e-mail address removed)"

the_email = "From: (e-mail address removed)\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

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.

require "bs-net/mail"

m = BsNet::Mail.new
m.headers.add :from, "(e-mail address removed)"
m.headers.add :to, "(e-mail address removed)"
m.headers.add :bcc, %w([email protected] (e-mail address removed))

m.headers.add :subject, "Some useless information"

plain = BsNet::Message.new
ct = BsNet::ContentType.new "text/plain", :charset => "utf-8"
plain.headers.add :content_type, ct
plain.headers.add :content_transfer_encoding, "8bit"
StringIpen plain.body do |b|
b.puts "This mail is coming with an attachment."
end
m.push plain

attachment = BsNet::Message.new
ct = BsNet::ContentType.new "text/comma-separated-values",
:charset => "utf-8", :name => "somefile.csv"

StringIO.new attachment.body do |b|
b.puts somedata

m.push attachment

m.sendmail

include a file called "the_attachment.pdf"? Thanks, Dave

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 <[email protected]>'
recipients '(e-mail address removed)'
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.

 

[Ollivier Robert]

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

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

rmail has it on its TODO for years

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 <[email protected]>',
'(e-mail address removed)',
'Some reports',
"See attached tab-delimited reports\n\n",
'/tmp/reports/*.txt'
