Rails - Mar 2008 - [ActiveRecord::validations] check CNAME or Empty

Hi I wanna check in my model if the field is conform to a CNAME OR is
empty

I''ve put something like this in my model :

  validates_format_of :cname, :with => /^[a-z0-9\-]+$/i,
                              :unless => :cname.strip == ''''
