I have an object called dealer. Dealer has two fields dealer_number
and sub_dealer_number. It must have 1 OR the other... but not both.
To validate this I have:
class Dealer < ActiveRecord::Base
validate :dealer_id?
private
def dealer_id?
if number.blank? && sub_number.blank?
errors.add_to_base("You must specify either a Dealer Number OR a
Sub Dealer Number.")
elsif (number.length > 0) && (sub_number.length > 0)
errors.add_to_base("You must specify either a Dealer Number OR
a Sub Dealer Number.")
end
end
end
This looks really messy to me. Is there a better way? Thank you for
your thoughts.
