Question

I use jquery_datepicker gem for selecting date in my form. However, datepicker passes param in the following format:

{"appointment"=>{"starts_at"=>"04/07/2012"}, "commit"=>"Submit", "id"=>"915"}

However, Rails requires that the date params must be in the following form:

"starts_at(1i)"=>"2012", "starts_at(2i)"=>"4", "starts_at(3i)"=>"7"

How should I parse my starts_at and get it back in the latter format?

The reason I need to manually parse it, because for some reason, rails confused 04/07/2012 as Jul 04, instead of April 07 (as jQuery datepicker displayed).

You can try to form date picker string at client side:

$( "#starts_at" ).datepicker({
    onSelect: function(dateText, inst) {
        dateText = $.datepicker.formatDate(
            'mm.dd.yy',
            new Date(inst.selectedYear, inst.selectedMonth, inst.selectedDay)
        );

        inst.input.val(dateText);
    },
});
