Hi, there's no magic happening. You're simply invoking save on the wrong instance. Just because one invokes save on a parent instance it doesn't automatically invoke save on its children. In most cases, this would be very inefficient. I would recommend learning/understanding more about ActiveRecord because this will help in the long run. Good luck,
