background process for mail delivery

here''s my problem:
I have a table with lots of emails to be sent at specified dates, and
I want a process that checks, let''s say every hour or so, that table
for mails to be sent, sends them and delete the records...

A very simple background process that call''s a method. If there was a
way of doing this not in background it''d be ok, I don''t care
if it
gets stuck every hour for a few seconds..

I know about remoterb, but really.. isn''t there an easier way? I
don''t
want to spend too much time on this stuff!


thanks everyone!
Luca

Re: background process for mail delivery

That thing is too big! And it''s meant for delivering mails like a
queue. I want to deliver them only when it''s time, they might stay
there for months, years..
Is there a way that doesn''t involve plugins, or just small ones?
like a thread.do stuff.. I don''t know..

bye

Re: background process for mail delivery

Is there some reason a cron job that POSTs an HTTP request to the Rails app
wouldn''t do the trick?

Re: background process for mail delivery

Look at this.. I know it''s a stupid try but I''d like to know
why it
doesn''t work:
put in some method..

Thread.new do
  while true do
    Notifier.deliver_message
    sleep 30
  end
end

Notifier is an action mailer class.
Shouldn''t this send an email every 30 seconds? Can it access the
Notifies class?

confused...

Re: background process for mail delivery

I have something that does exactly that.

It uses the Daemons gem.  I start it by doing

ruby scripts/outgoing_email_thread.rb start/stop/restart

Basically this thread just loops forever.  It wakes up and checks for
stuff to do by asking the database
"Notification.find(:all, :conditions => ''b_distribute =
true'').each do
|n|"

So for me I have a table called Notifications that things get inserted
into by my application.  If they want batch mode distribution, they
set b_distribute = true.  This thing gets them, does some mojo and
then sends out notifications.  Don''t get caught up in my crazy code as
much as the idea of a Daemon thread you start that loops and does your
stuff.  My app has about 4 of this bad boys running checking incoming
email, sending email, gathering SMS messages, etc.

#!/usr/bin/env ruby
##
require ''rubygems''        # if you use RubyGems
require ''daemons''

Daemons.run_proc("outgoing_email_thread", {:dir_mode => :normal,
:dir
=> ''tmp/pids''} ) do
  require "/var/www/yoursite/current/config/environment.rb"  # This
has to be a full path to your environment.rb file.  scratched my head
here.
  loop {
      logger.info(''outgoing_email_thread: Checking for outgoing email
messages at '' + Time.now.to_s)

      # Find any notifications that need to be distributed
      Notification.find(:all, :conditions => ''b_distribute
true'').each do |n|
        begin
          n.attach_to_subscribers
        rescue Exception => exc
          logger.error("outgoing_email_thread: sending email.." +
exc.message)
          logger.error(exc.backtrace.join("\n"))
        end
        n.update_attributes(:b_distribute => false)
      end

      # Now notify any users based on Readings
      Reading.find(:all, :conditions => ''is_sent =
false'').each do |r|
        begin
          r.update_attribute(:is_sent, true)
          if r.connector.source.bsd.setting.mail_event &&
r.connector.source.bsd.email_tested
            email = NotificationMailer.create_notify(r.connector,
r.notification)
            email.set_content_type("text/html" )
            NotificationMailer.deliver(email)
          end
        rescue Exception => exc
          logger.error("outgoing_email_thread: sending email.." +
exc.message)
          logger.error(exc.backtrace.join("\n"))
        end
      end
      EmailMessage.find(:all, :conditions => [''is_sent =
?'',
false]).each do |email|
        email.send_me
      end
      sleep 13  # My lucky number
  }
end

Hope this is helpful.

You want ar_mailer...

http://blog.segment7.net/articles/2006/08/15/ar_mailer

"Even deliviring email to the local machine may take too long when you  
have to send hundreds of messages. ar_mailer allows you to store  
messages into the database for later delivery by a separate process,  
ar_sendmail."
