Meteor.js: Find all documents and return in reverse natural order

Question

I am trying to return all documents in a collection, to use it with an {{#each}} in my template. My code looks like this:

return Answers.find({}, {sort: {$natural:-1}})

But the documents are returned in natural order (not reverse). Does anyone know why? I got the $natural selector from the MongoDB documentation, so I don't see what's wrong.

Can't tell why don't it returns in reverse order.

But you can create an array in the template helper method and return reverse of an array using array.sort() or array.reverse() functions.

For ex: Say you Answers collection looks like this:

Answers({ansNo: 1, ansBody: "body1"},
        {ansNo: 2, ansBody: "body2"},
        {ansNo: 3, ansBody: "body3"});

And the array to be returned is:

var AnswersArr = new Array();

then in your template helper :->

var tempCollection = Answers.find({});
tempCollection.forEach(function(data){
    var obj = {ansNo: data.asnNo, ansBody: data.ansBody};
    AnswersArr.push(abj);
});

AnswersArr.sort(function(a, b){return b.ansNo - a.ansNo;});  //sort in reverse order

return AnswersArr;
