Angularjs groupBy + orderBy

Question

I am using groupBy from angular-filter to group an array of objects by their date property.

Answer 1

We can achieve this by ordering the data in controller & converting groupBy output to Array.

In controller, order the records before sending it to view :

$scope.events = $filter('orderBy')(events, '-date');

Now the template, receives data in sorted order. After grouping, we need to transform it to Array :

     
{{ day | dayEvents[0].date: mediumDate }}
