How to fix mongoose "gt" and "lt" not working - node.js

Question

I'm trying to get all staff members within a given date range using mongoose ODM, but can't seem to find a way.
I tried using different date formats, but came up with storing ISO date in my db. Now it saves and retrieves dates as ISODate("2018-12-23T00:00:00Z") format.
But, what I want is to get all staff members using a date range given using $gte and $lte
/**
* Get all attendance of one member for a specific time frame(a month)
*
*/
module.exports.getAttendanceTimeFrame = function(params,callback){
console.log(new Date(params.frm).toISOString());
AttendanceStaff.find({staff_id: params.staff_id, date:{$gte:params.frm, $lte:params.to}},callback);
}
This gives nothing but this gives all staff members who signed that day
Model.find({date:'2018-12-22'},callback);

Answer 1

That's because your params are sending date+time, whereas gte and lte only take date. The output of your log console.log(new Date(params.frm).toISOString()); should show timestamp

Answer 2

A foolish question. Pardon me..
I actually found what was wrong with it.. It was a friggin TYPO
here is it we can implement this using different approaches
since we store only a date, the mongoose will automatically convert all values we provide to ISODate format (date+time). Its actually very good because a similar pattern for a date or a time. So simply we can use the above code i have given It will work fine
/**
* Get all attendance of one member for a specific time frame(a month)
*
*/
module.exports.getAttendanceTimeFrame = function(params,callback){
console.log(new Date(params.frm).toISOString());
AttendanceStaff.find({staff_id: params.id, date:{$gte:params.frm, $lte:params.to}},callback);
}
actually instead of staff_id: params.staff_id, all I had to do was params.id
because thats how I defined the staff_id in http GET req. which is /staff/:id/:frm/:to
anyways we can even use where to do this as well a different approach...
/**
* Get all attendance of one member for a specific time frame(a month)
*
*/
module.exports.getAttendanceTimeFrame = function(params,callback){
console.log(params.id);
AttendanceStaff.find({date:{$gte:params.frm, $lte:params.to}}).sort({date:-1}).where({staff_id:params.id}).exec(callback);
}
so that's it ...
