誰知道我的ajax有什么問題？

Question

我有這個$ .ajax方法調用：

var w_command = "add_holiday"
var w_type = "POST"
var w_id = "123321"

$.ajax(
    {
    type: w_type,
    url: w_command,
    parameters: 
        {
        to_find_id: w_id
        },
    success:function()
        {
        //Do something on success      
        alert('done');
        }
    });

從控制器調用此方法：

def add_holiday
    RHoliday.create(holiday_id: params[:to_find_id].to_s, group_id: @group.id.to_s)
end

我也得到alert('done'); 告訴我，AJAX請求有效，並找到方法。 那為什么它仍然沒有創造任何東西呢？

沒有什么叫做parameters ，它是data

$.ajax({
    type : w_type,
    url  : w_command,
    data : {
        to_find_id: w_id
    },
    success:function()  {
        //Do something on success      
        alert('done');
    }
});
