I need to use an activerecord model in a ruby script that is run from  
outside rails, so I need to boot rails from my script, otherwise I  
get  
uninitialized constant ActiveRecord  
I tried adding  
require ‘config/boot’  
to the script to boot rails before running the script, but that did  
not help…

To load the full rails environment you need to require config/  
environment (you might want to investigate script/runner)
