Rails - May 2009 - Setting Up Setters

If I have a setter method that needs to manipulate the incoming value
before setting itself, how can I do this without it be self
referencing? In the example below, I''ve defined
"start_date=", so how
do I now save a value to start_date?

thx

Ex:
class Event
   def start_date=(new_start_date)
       self.start_date = new_start_date unless new_start_date >start_date
   end
end

Look for write_attribute
