There are slightly different answers depending on what you want to do.  
I’m assuming that you do want to use your app’s models (ie it’s not  
just activerecord you want, you need to setup the environment

The easiest way is to use script/runner, which will setup the  
environment for you. Failing that, requiring config/boot and config/  
environment will load up the rails environment for you. (those aren’t  
on the load path, so you’ll need something like require  
File.dirname( **FILE** ) + ‘/…/config/boot’ depending on where your  
script is in relation to the rest of the app)

I’d suggest you may also want to make this script get run by a rake task

/lib/tasks/whatever.rake

desc “whatever you want”  
task :something =\> :environment do  
Call::The.code\_you\_want  
end

then just get cron to call the rake command.

require ‘rubygems’

it won’t get you the connection setup in your database.yml,  
or any of the subclasses of ActiveRecord::Base that you’ve set up in  
your project.

Just depends what you’re trying to do.

Creating a rake task is the far best solution. You can access all your  
Models ideal for cron jobs. I use this on one of my projects which  
updates/add many models every night.
