在猫鼬钩子中调用函数'post save'返回相同的文档

Question

在我的模式中，我有一个类似的帖子保存钩子

DateInfoSchema.post('save', function (doc) {
    var newDoc = helper. getListTimeRate(doc);
    console.log(newDoc);
});

然后我有一个帮助程序模块，因为我有一个计算日期范围的函数     让我们考虑“ doc”的开始日期和结束日期，以便我要计算从开始日期到结束日期的日期范围

 module.exports = {
        getListTimeRate: function (data, yearEndDate) {
        var toDate = new Date(),
            weekName = ["Sun","Mon","Tue","Wed","Thu","Fri","Sat"];

        Date.prototype.addDays = function(days) {
           var dateAdd = new Date(this.valueOf());
           dateAdd.setDate(dateAdd.getDate() + days);
           return dateAdd;
        };

        function getDates(startDate, stopDate) {
            var dateArray = [];
            var currentDate = startDate;
            if (currentDate == undefined){
                while (currentDate <= stopDate) {
                    dateArray.push(currentDate);
                    currentDate = currentDate.addDays(1);
                }
                return dateArray;
            }else {
                var newCurrentDate = new Date(currentDate.toISOString().substr(0,10));
                var newStopDate = new Date(stopDate.toISOString().substr(0,10));
                while (newCurrentDate <= newStopDate) {
                    dateArray.push(newCurrentDate);
                    newCurrentDate = newCurrentDate.addDays(1);
                }
                return dateArray;
            }
        }
        function calcRange(entry) {
            // function get time
            var dateList = [],
            newList = [];
            if (toDate < entry.endDate) {
                // calc from endDate
                newList = getDates(entry.startDate, entry.endDate);
                //status often
                selectDateFromOften();
            } else {
                if (yearEndDate) {
                    newList = getDates(entry.startDate, entry.endDate);
                } else {
                    newList = getDates(entry.startDate, toDate);
                }
                // calc from toDate
                //status often
                selectDateFromOften();
            }
            function getDateTimeAnother() {
                if (entry.hour) {
                    var setHour = entry.hour.getHours(),

                }
                dateList.forEach(function(entryDate){
                    entryDate.setHours(setHour);
                    entryDate.setMinutes(setMin);
                    entryDate.setSeconds(setSecond);
                });

                entry.rangeDate = dateList;
                var compareUsedDate = [];
                _.forEach(entry.frequencyId, function(value) {

            }
        }
        return data;
    }
    };

但是在'newDoc'钩子中没有'rangeDate'字段。谁能帮我解决这个问题？谢谢。
