ng-class - finding a value inside object - angularjs

Question

I have an object that looks like this:
$scope.things = [
{
name: 'Bob!',
short_name: 'bob',
info: 'something something'
},
{
name: 'Steve',
short_name: 'steve',
info: 'something something something'
},
];
I loop through them like this and add an ng-click:
<div ng-repeat="thing in things" ng-click="addThing(thing.name, thing.short_name, thing_info" ng-class="thingClass(thing.name)">content goes here</div>
the ng-click="addThing()" basically bunches up the values and adds them to the object.
When clicked, it should add the class selected - this worked fine and dandy when I wasn't using a multidimensional object, because it was simply looking for name inside the object / array (at this point, I think it's an object... but at the time, it was an array)
I can't work out how to do the equivalent to this...
$scope.thingClass= function(name) {
if($scope.thingSelected.indexOf(name) != -1) {
return 'selected';
}
};
...with the object as it now stands. I've tried to adapt a few answers from here that I found through google, such as:
$scope.teamClass = function(name) {
var found = $filter('filter')($scope.thingSelected, {id: name}, true);
if (found.length) {
return 'selected';
}
};
...but with no joy.
Can anyone point / nudge me in the right direction?

You could simply pass the thing object to thingClass:
... ng-class="thingClass(thing)" ...
and implement thingClass as follows:
$scope.thingClass= function(thing) {
return $scope.thingSelected.indexOf(thing) >= 0 ? 'selected' : '';
}
And maybe your should apply this technique to addThing also:
... ng-click="addThing(thing)" ...
$scope.addThing = function(thing) {
if ($scope.thingSelected.indexOf(thing) < 0)
$scope.thingSelected.push(thing);
}
But instead of tracking the selected things in an array its much easier to introduce a selected property in each thing:
$scope.addThing = function(thing) {
thing.selected = true;
}
$scope.thingClass= function(thing) {
return thing.selected ? 'selected' : '';
}
