Query On Date For Posts Created The Last 24h

I have this schema with a date for the field 'created_at': var post = new mongoose.Schema({ text : String, created_at : {type : Date, index : true}, pos : {latitude: Nu

Solution 1:

To get posts created in the last 24hrs, you could get the current time, subtract 24 hours and get the value of start date to use in your date range query:

var start = newDate(newDate().getTime() - (24 * 60 * 60 * 1000));

Post.find({ "created_at": { "$gte": start } }).exec(callback);

If you want to know more about $gte, check the following article:

https://docs.mongodb.org/manual/reference/operator/query/gte/

---

With the momentjs library this can be simply

var start = moment().subtract(24, 'hours').toDate();
Post.find({ "created_at": { "$gte": start } }).exec(callback);

You could also define a date default with a function instead of the pre hook middleware:

varpost=newmongoose.Schema({text :String,created_at : {type :Date, default:Date.now, index :true},pos : {latitude:Number, longitude:Number},created_by : {type :Schema.Types.ObjectId, ref :"UserSchema"}
});

Solution 2:

I have try following code for date range in php+mongodb and its working fine so try like this.

$time1 = new DateTime('Your Date');
$from = new MongoDate($time1->getTimestamp());
$check_date = date('d-m-Y', strtotime($filter_data['to']));

Your Condition is look like this

'created_on'=>array($gt' => $check_date)
