When I submit my form I can see the date being sent to in the post. However, It doesn\'t save the date. If I do a date check it says it is not in the proper format. Here
As noted by @BaronVonBraun above rails doesn't seem to handle that format. Changing it as he suggested worked. However, for those wanting a different format than yy-mm-dd you can use the following. The user sees the format you want while rails gets the format it needs.
$j(function(){
$j("#show_date").datepicker({altField: '#mile_date', altFormat: 'yy-mm-dd'});
});
The show_date is the id of the field they see and the mile_date is a hidden field with the date rails needs.
Here is the documentation.
