Rails - Apr 2008 - QUICK QUESTION: Run a Ruby File inside of Model

Hi,

I''m trying to run a ruby file in lib from inside of a model.  How can I
run a ruby file from inside of a model?

In this example, Thing.rb is my model.  I''m trying to run do_update.rb.
How can I call this from inside of Thing.rb?

Thing.rb
**********************
def update_things delete_cache
  things = Thing.find(:all, :conditions => "updated = false")

  ### Run an updater in "lib/updater/do_update.rb"
  #### What goes on this line?   # ruby script/runner do_update.rb
end

Sorry, the above thing should say:
> Thing.rb
> **********************
> def update_things delete_cache
>   things = Thing.find(:all, :conditions => "updated = false")
> 
>   ### Run an updater in "lib/do_update.rb"

If you don''t need to pass too many params,
system("path/to/script.rb
#{param1}....") will work (assuming it''s sh-banged).  If you want
it
to be asynchronous (i.e. Rails starts the script then keeps going, and
doesn''t care how long the script takes over to the side), I would
suggest deamonizing your script and have it poll a database every X
secs to see if an action is requested, do it''s thing, and mark the
task as complete or remove it from the table.  This also allows you to
off-load and parallelize (if you use record locking and multiple
daemons) other compute-intensive tasks from Rails.  Your Thing.rb
model would simply set a flag or insert a record into some queue table
that the script polls.  Using Active Record outside of rails, this is
a snap.

If these two conditions aren''t true, turn your script into a Module
with methods and use it as a mixin to the model classes that need to
call it.  Or just copy and paste the code ;).
