angular select ng-selected not working (with <option ng-repeat>)

Question

I've spent an hour and tried every conceivable permutation of properties to bind a select to a model as object, and ng-selected does nothing.

<select ng-model="localModel.priceType">
    <option 
            ng-repeat="item in vm.priceTypes"
            ng-selected="localModel.priceType == item"
            ng-value="item"
            >{{item.name}}</option>
</select>

or

<select ng-model="localModel.priceType">
    <option 
            ng-repeat="item in vm.priceTypes"
            ng-selected="localModel.priceType.id == item.id"
            ng-value="item"
            >{{item.name}}</option>
</select>

or

<select ng-model="localModel.priceType">
    <option 
            ng-repeat="item in vm.priceTypes track by item.name"
            ng-selected="localModel.priceType.name == item.name"
            ng-value="item"
            >{{item.name}}</option>
</select>

The select list renders correctly, option values look funky i.e "object:875". and selected does not work.

I need ng-model to be the object, not object.someId.

solved this by using ng-options instead of <option> ng-repat

<select ng-model="localModel.priceType" ng-options="item as item.namefor item in vm.priceTypes track by item.name"></select>

ngValue expects a string for the ngValue. To use ngRepeat with the <option> tag, then use value="{{item}}" instead of ng-value. Expand the snippet below to see it working.

angular.module('myApp', [])
  .controller('ctrl', function($scope) {
    $scope.vm = {
      priceTypes: [{
          id: 3,
          name: 'pound'
        },
        {
          id: 5,
          name: 'Yen'
        },
        {
          id: 6,
          name: 'dollar'
        }
      ]
    };
    //select model value
    $scope.localModel = {
      priceType: $scope.vm.priceTypes[1]
    };
  })

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular.min.js"></script>
<div ng-app="myApp" ng-controller="ctrl">
  <select ng-model="localModel.priceType">
  <option 
            ng-repeat="item in vm.priceTypes as item"
            ng-selected="localModel.priceType.id == item.id"
            value="{{item}}"
            >{{item.name}}</option>
</select>
  <div>
    priceType: {{ localModel.priceType }}
  </div>
</div>

A simpler approach is to use ngOptions on the <select> tag, with a combination of forms:

select as label for value in array track by expr

Refer to the comprehension_expression forms in the Arguments section under Usage for more information.

angular.module('myApp', [])
  .controller('ctrl', function($scope) {
    $scope.vm = {
      priceTypes: [{
          id: 3,
          name: 'pound'
        },
        {
          id: 5,
          name: 'Yen'
        },
        {
          id: 6,
          name: 'dollar'
        }
      ]
    };
    //select model value
    $scope.localModel = {
      priceType: $scope.vm.priceTypes[1]
    };
  })

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.0/angular.min.js"></script>
<div ng-app="myApp" ng-controller="ctrl">
  <select ng-model="localModel.priceType" ng-options="item as item.name for item in vm.priceTypes track by item.name">
</select>
  <div>
    priceType: {{ localModel.priceType }}
  </div>
</div>
