Creating Stats Out Of Array With Angularjs

I have an array of objects looking like this: [ { 'date':'20/11/2014', 'time':'17.54.39', 'car':'369', 'driver':'Jenny', 'from':'Luna House', 'destination

Solution 1:

If you use lodash it's easier. This would be a way of doing it:

HTML:

<bodyng-app="myApp"><h1>Hello AngularJS!</h1><divng-controller="myCtrl">
      {{hello}}
      <pre>{{data | json}}</pre><pre>{{data2 | json}}</pre><divng-repeat="(monthName, monthValue) in data2"><pclass="month-header">{{monthName}}</p><tableng-repeat="(groupName, groupValue) in monthValue"><tr><th>{{groupName}}</th><th>Trips</th><th>Duration</th></tr><trng-repeat="(tripName, tripValue) in groupValue"><td>{{tripName}}</td><td>{{tripValue.trips}}</td><td>{{tripValue.duration}}</td></tr></table></div></div></body>

JS:

var dataByMonth = _.groupBy($scope.data, function(record) { returnmoment(record.date, 'DD-MM-YYYY').format('MMMM YYYY'); });
  console.log(dataByMonth);
  dataByMonth = _.mapValues(dataByMonth, function(month) {
   var obj = {};
   obj.Cars = _.groupBy(month, 'car');
   obj.Drivers = _.groupBy(month, 'driver');

   _.each(obj, function(groupsValue, groupKey) {
      obj[groupKey] = _.mapValues(groupsValue, function(groupValue) {
         return _.reduce(groupValue, function(sum, trip) {
           sum['trips']++;
         //addDuration(sum.duration, car.duration); return sum;
         }, {trips: 0, duration: ''})
       });
   })

   return obj;
  });
 console.log(dataByMonth);
