Use AngularJS Variable, where another AngularJS Variable matches its ID -

i have ng-repeat statement want show image. image however, should chosen ng-repeat's id matches image object's id.

i unsure of how properly, here psuedo code of trying do.

<tr ng-repeat="user in rosterdata | orderby:'name'">    <img ng-src="{{champion.imagename user.id = champion.id}} /> </tr> 

remember champion.id object of champions, want make sure right champion.name match right champion.id when matches current ng-repeat user.id

it better if check logic inside controller:

<tr ng-repeat="user in rosterdata | orderby:'name'">    <img ng-src="{{getimage(user.id)}} /> </tr> 

in controller:

    $scope.getimage = function(userid) {        var image = "defaultimage";        $scope.champions.foreach(function(champion) {          if(champion.id===userid) {                image = champion.image;          }        });       return image;    }
