angularjs - Kendo treeList 数据源 - 未绑定(bind)远程数据

Question

我已经为 treeList 编写了一个指令，并将数据从远程服务调用绑定(bind)到它。下面是指令链接方法中 TreeListDataSource 的代码:

scope.treeListOptions.dataSource = new kendo.data.TreeListDataSource({
  transport: {
    read: function(options) {
      scope.getData().then(function(dataToBeDisplayed) {
        options.success(dataToBeDisplayed);
      }, function(error) {
        $log.error(error);
      });
    },
    error: function(e) {
      alert(e.status + e.errorThrown);
    },
  },
});

scope.treeListOptions.dataSource.read(); 

以下是 TreeList 指令定义:

var TreeListDirectiveDefinition = {
  restrict: 'E',
  replace: true,
  template: '<div><kendo-treelist k-options="treeListOptions"></kendo-treelist></div>',
  scope: {
    columns: '=',
    getMethod: '&'
  },
  link: linkTreeList
};

当我看到绑定(bind)到 scope.treeListOptions.dataSource.data() 的数据时，添加了许多新属性，如下所示:

// parent element
C.define.init
PartExamined: "test"
StudyUid: "1.3.6.1.4.1.30071.8.56809868014.4964677242993979.234.56616"
_events: Object
_loaded: true
dirty: false
hasChildren: true
id: 1
parent: ()
parentId: null
parentIdField: "parentId"
uid: "1ca6302c-b1ad-493f-b002-d2032a548a80"
__proto__: i.extend.i


//child element
C.define.init
PartExamined: "test2"
SeriesInstanceUid: "1.3.6.1.4.1.30071.8.56809868014.4964677242993979.234.56617"
_events: Object
_loaded: true
dirty: false
hasChildren: false
id: 2
parent: ()
parentId: 1
parentIdField: "parentId"
uid: "953bc7a7-e5e8-4f26-a120-b13402c6cce4"
__proto__: i.extend.i

属性如 parent: (), parentIdField: "parentId", _loaded: true,dirty: false, hasChildren: true 由 TreeListDataSource 添加。

这是正确的数据格式吗？因为 TreeList 正在显示 “没有要显示的记录” .

谁能帮我解决这个问题？

更新
这是为 treeList 创建的 angular 指令的链接: http://jsfiddle.net/yuqorcvL/15/

该指令仍然无效。任何帮助将不胜感激。

谢谢。

您应该添加 schema在 scope.treeListOptions.dataSource

schema: {
                        model: {
                            id: "EmployeeID",
                            parentId: "ReportsTo",
                            fields: {
                                ReportsTo: { field: "ReportsTo",  nullable: true },
                                EmployeeID: { field: "EmployeeId", type: "number" },
                                Extension: { field: "Extension", type: "number" }
                            },
                            expanded: true
                        }
                    }

看 that example在 Kendo 文档中
