日期之间的Meteor.js / MongoDB查询不返回数据

Question

I have the following piece of code for getting results back from a Mongo Collection.

var currentDate = moment().toISOString();
// RETURNING: 2016-12-10T20:36:04.494Z

var futureDate = moment().add(10, "days").toISOString();
// RETURNING: 2016-12-20T20:36:04.495Z

return agenda = Agendas.find({
  "agendaDate": { '$gte': currentDate, '$lte': futureDate }
});

And the date is stored in MongoDB Collection like below;

{ 
"_id" : ObjectId("584877e56466dd236cd95f15"), 
"agendaDate" : ISODate("2016-12-12T17:28:25.000+0000"), 
"agendaTime" : "20:59", 
"agendaEvent" : "Test event" 
}

However, I am not getting any results returning as all. I have set up 3 test documents, 2 in the range, 1 outside.

Can anyone explain what I'm doing wrong and help rectify the code?

Answer 1

You need to compare dates against actual date objects, not strings representing them.

That is, you need to get the date from your moment objects, using the toDate() method.

var futureDate = moment().add(10, "days").toDate();

Answer 2

Well actually moment.toISOString() returns a string, so you can't use it to compare with date object in your mongodb query. You should consider creating a date object for that. Regs, Yann
