Rails - Aug 2007 - scheduled tasks on rails

How do you set up automated tasks on rails. Say I wanted to send an
update mailing every night at midnight to my users, or every night
connect to a external database to update information on my database?

you can write a rake task and then invoke it with a cron-like tool 
(depending on your OS and preferences)

writing rake tasks is pretty straight-forward. In your rails directory  
there are a lot of tasks you can take a look for getting the flavour of 
it. They are under vendor/rails/railties/lib/tasks

I usually do something pretty simple:  I create a class in the vendor
directory, and then setup a cron job to run script\runner with that
file.  For example:

I have a file called session_cleaner.rb in \vendor like this:

class SessionCleaner
  CGI::Session::ActiveRecordStore::Session.destroy_all( [''updated_at
< ?'', 240.minutes.ago] )
end

Then I have a cron job that runs:

ruby script\runner SessionCleaner -e production


I''ve also used this method for nightly emails to process new user
signups, etc.
