Sorry, not enough information.. again.. My view has 4 fields for new records: sex month, day, and year. It also has a new person link that creates as many new empty records as needed. After the 'Save Changes' link is clicked, my controller then validates these fields and makes a birthday field using whatever is entered ( Sounds like I should put this action in the model ). The problem comes if a new person record is left without any data. It looks like the model isn't saving these empty records, but they are still in the @household.people collection, killing a call to sort_by. All this trouble to put the birthdays in order..
