node.js - Remove record WHERE it is older than 10 mins in MongoDB? -


i new node js , mongodb (coming sql background). trying implement function removes records in collection 'journeys' timestamp older 10 mins. have done far:

connection.open(function(err, connection) {     var database = connection.db(database);     database.collection(journey_collection, {}, function(err, journeys) {         var = new date().gettime() / 1000 - 10 * 60;         journeys.remove({timestamp : ???}, function(err, result) {             if(err != null)                 console.log('a refresh error occurred');             connection.close();         });     }); });

am on right track? should putting in place of "???" ?

you're on right track.

your "???" should in form {$lt:varname}

var tenminutesold = new date() tenminutesold.setminutes(tenminutesold.getminutes()-10) journeys.remove({timestamp: {$lt:tenminutesold}}, function(err, result) {

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
