Retrieving a link from $ firebaseArray to create a new reference object

Related to this question , I need to be able to get an item from the collection as a Firebase link, i.e. given $firebaseArrayI need $firebaseObject, pointing to one of its elements. Unlike this example, I can’t just hardcode the path to the array and take it from there, because the location of the array will be different. And I cannot use $firebaseArray.$getRecord()either the object provided by mine ng-repeat, which follows array.$save(), because I may need push()for this element.

So, I settled on this reusable approach:

In the service:

function selectElement(array, element) {
  var obj = $firebaseObject(array.$ref().child(element.$id));
  return obj;
}

In the controller:

function onItemClicked(e) {
  vm.selected = dataservice.selectElement(vm.observations, e);
}

In the template:

<div class="list-item" ng-repeat="o in vm.observations" ng-click="vm.onItemClicked(o)">

The first line selectElementthrows an error:array.$ref(...).child is not a function at Object.selectElement

array , , array.$ref() :

Y {k: Ji, path: P, n: Ce, pc: true}

. ? Firebase ?
