For ActiveRecord models, this method is called as a before_validation callback to ensure that the CSV values have been update to the ‘_csv’ columns appropriately. The user might have used an array modifier directly (e.g. << or push), which we wouldn’t see. So, to make sure the database gets updated appropriately, we do this.
