# "order_finished" would invoke template file "app/views/messages/order_finished.rhtml".
# Note: you need to set the sender afterwards if this should not be a system message.

# Example:
# Message.from_template(
# 'order_finished',
# {:user => user, :group => ordergroup, :order => self, :results => results, :total => group_order.price},
# {:recipient_id => user.id, :recipients => recipients, :subject => "Bestellung beendet: #{self.name}"}
