--------------------
Everything here is working as expected. ONLY the conditions part is
not working...
The problem is that self.id is NOT the @my_design.id (the id of the
active record design instance), but the object_id of the instance. HOW
can I tell ActiveRecord that I want the @my_design.id ???
Set conditions to 'title =#{self.id}' (make sure it's single quotes
not double quotes). Activerecord should interpolate it for you.
