使用ng-options而不是ng-repeat填充下拉框

Question

我是angularJS的新手，我一直试图填写下拉列表框大约一周。我不能让它来填补拯救我的生命。我正确设置了吗？

angularJS代码

var CapitalRequestMultiMillInquiryController = function ($scope, $rootScope, $modal, $window, UsersService) {

$rootScope.title = 'Capital Request Multi Mill Inquiry';
$scope.mill = '';
$scope.jobNumber = '';
$scope.description = '';
$scope.amount = '';
$scope.amountOperator = '';
//below is a textbox entry may need to change
$scope.openonly = '';
$scope.users = '';
$scope.selectedProjectManager = '';


UsersService.getUsersWithId().then(function (objectTypes) {
    $scope.getUsersWithId = _.filter(objectTypes, function (objectTypes)
    {
        return objectTypes.inactive == false;
  });       
});



$scope.search = function() {
    //for each mill

    CapitalRequestService.searchMulti("http://coucmmsweb.pca.com/CapitalRequest/Inquiry", authenticatedUser.userName.toUpperCase(), $scope.mill, $scope.jobNumber, $scope.description, $scope.selectedProjectManager, $scope.amount, $scope.amountOperator, $scope.openonly).then(function (results) {
        $scope.counce = results;
    });
    CapitalRequestService.searchMulti("http://filcmmsweb.pca.com/CapitalRequest/Inquiry", authenticatedUser.userName.toUpperCase(), $scope.mill, $scope.jobNumber, $scope.description, $scope.selectedProjectManager, $scope.amount, $scope.amountOperator, $scope.openonly).then(function (results) {
         $scope.filer = results;
     });
    CapitalRequestService.searchMulti("http://tomcmmsweb.pca.com/CapitalRequest/Inquiry", authenticatedUser.userName.toUpperCase(), $scope.mill, $scope.jobNumber, $scope.description, $scope.selectedProjectManager, $scope.amount, $scope.amountOperator, $scope.openonly).then(function (results) {
        $scope.tomahawk= results;
    });
    CapitalRequestService.searchMulti("http://tridentval.pca.com/api/Inquiry/Inquiry/CapitalRequestMultiMillInquiry/Search", authenticatedUser.userName.toUpperCase(), $scope.mill, $scope.jobNumber, $scope.description, $scope.selectedProjectManager, $scope.amount, $scope.amountOperator, $scope.openonly).then(function (results) {
        $scope.valdosta = results;
    });
    CapitalRequestService.searchMulti("http://tridentder.pca.com/api/Inquiry/Inquiry/CapitalRequestMultiMillInquiry/Search", authenticatedUser.userName.toUpperCase(), $scope.mill, $scope.jobNumber, $scope.description, $scope.selectedProjectManager, $scope.amount, $scope.amountOperator, $scope.openonly).then(function (results) {
        $scope.deridder = results;
    });
   }
};

这是我的服务......

app.service('UsersService', function ($http, cache) {
return {
    getUsersWithId: function () {
        var objectTypes = cache.get('usersWithId');
        if (!objectTypes) {
            return $http({ method: 'JSONP', url: "/api/core/users/userswithid?callback=JSON_CALLBACK", params: {} }).then(function (result) {
                if (result.data.success) {
                    cache.put('usersWithId', result.data.data);
                    return result.data.data;
                } else {
                    return [];
                }
            });
        } else {
            var deferred = $q.defer();
            deferred.resolve(objectTypes);
            return deferred.promise;
        }
    }
};
});

和我的控制器..

Public Class UsersController
Inherits System.Web.Mvc.Controller

'
' GET: /Users
<PCA.Core.Web.CompressionFilter> _
Function UsersWithId(callback As String) As ActionResult
    Dim res As New PCA.Core.Web.JSON.Response

    Dim catList As New List(Of ViewModels.Core.User)
    For Each u In Trident.Core.Globals.TridentApp.ApplicationCache.Users.AllWithUserID
        catList.Add(New ViewModels.Core.User(u))
    Next
    Try
        res.success = True
        res.message = ""
        res.data = catList.OrderBy(Function(c) c.fullName)
        Return New PCA.Core.Web.JSON.JSONPResult() With { _
             .Data = res,
             .Callback = callback
            }
    Catch ex As Exception
        res.success = False
        res.message = ex.Message
        res.data = ""
        Return New PCA.Core.Web.JSON.JSONPResult() With { _
             .Data = res,
             .Callback = callback
            }
    End Try
End Function

End Class

和我的观点

          <div class="form-group">
                    <label>
                        Project Manager:&nbsp;&nbsp;
                        <select style="width: 180px" ng-options="user.value as user.userName for user in allUsers" ng-model="selectedProjectManager">
                            <option value=""></option>
                        </select>
                    </label>
                </div>

UserController是一个不同于这个特定页面控制器的控制器我的老板告诉我，服务调用正确的控制器无关紧要我只需要设置我的角度函数并在视图中调用它应该工作他说...他们都去圣诞假期，我试图弄清楚这一点，任何帮助将不胜感激。
