I write:  
./script/generate manage\_scaffold product PARENT=structure

but, when I try to use ENV[‘PARENT’] it always is nil value.  
How can I get parameter value from option in command line, when  
scaffold is generating model?

P.S. “manage\_scafold” is my owner plugin:

require ‘rails\_generator/generators/components/scaffold/  
scaffold\_generator’

class ManageScaffoldGenerator \< ScaffoldGenerator
