Ember.js 内容准备就绪时通过DS.FilteredRecordArray循环

我的路线定义如下：

setupController: function (controller, model) {
    var analyticsRuns,
        store = this.get('store'),
        exerciseRunId = this.controllerFor('analyticsContext').get('exerciseRunId');

    // Query the server for all runs that belong to this exercise run.
    // The results of the query will be loaded into the store so we can start
    // filtering them, thus taking advantage of live updates.
    // (see http://emberjs.com/guides/models/frequently-asked-questions/)
    store.find('analyticsRun', { 'exerciseRunId': exerciseRunId });

    analyticsRuns = store.filter('analyticsRun', function (analyticsRun) {
        return analyticsRun.get('exerciseRunId') === exerciseRunId;
    });

    controller.set('model', analyticsRuns);
    controller.set('exerciseRunId', exerciseRunId);
    controller.set('analyticsTemplates', store.find('analyticsTemplate'));
    controller.set('exerciseRun', store.find('exerciseRun',exerciseRunId));

    controller.send('setAnalyticsRunSelectOptions');
}

在我的控制器操作中，“setAnalyticsRunSelectOptions”定义为：

    setAnalyticsRunSelectOptions: function () {
        var options = [], run;
        //console.log(this.get('content'));
        //console.log(this.get('content.length'));

        //for(var i= 0,len=this.get('content.length');i<len;i++){
        //    run = this.get('content').objectAt(i);
        //    options.push({"id": run.get('id'), "label": run.get('id') + " " + run.get('name')});
        //}

        console.log(this.get('content'));
        this.get('model').forEach(function (run) {

            options.push({"id": run.get('id'), "label": run.get('id') + " " + run.get('name')});
        });

        this.set('analyticsRunSelectOptions',options);
    }

setAnalyticsRunSelectOptions:函数（）{
var选项=[]，运行；
//console.log（this.get（'content'）；
//log（this.get（'content.length'）；
//对于（var i=0，len=this.get（'content.length'）；i您没有在
setupController
钩子中设置控制器的内容。在
setupController
钩子中包括以下行：

controller.set('content', model);

您可以知道何时使用
then
方法加载
store.find（'analyticsRun'）
。因此您将能够循环加载的数据

更新的代码如下所示：

setupController: function (controller, model) {
    var analyticsRuns,
        store = this.get('store'),
        exerciseRunId = this.controllerFor('analyticsContext').get('exerciseRunId');

    // Query the server for all runs that belong to this exercise run.
    // The results of the query will be loaded into the store so we can start
    // filtering them, thus taking advantage of live updates.
    // (see http://emberjs.com/guides/models/frequently-asked-questions/)
    store.find('analyticsRun', { 'exerciseRunId': exerciseRunId }).then(function() {
        controller.send('setAnalyticsRunSelectOptions'); 
    }); 

    analyticsRuns = store.filter('analyticsRun', function (analyticsRun) {
        return analyticsRun.get('exerciseRunId') === exerciseRunId;
    });

    controller.set('model', analyticsRuns);
    controller.set('exerciseRunId', exerciseRunId);
    controller.set('analyticsTemplates', store.find('analyticsTemplate'));
    controller.set('exerciseRun', store.find('exerciseRun',exerciseRunId));   
}

谢谢Marcio，这对我很有效。我现在觉得自己超级愚蠢，因为我以前一直在尝试对“analyticsRuns”变量执行“then”！
