Question

我会得到一个对象的belongsTo关系。什么是最好的方法？我看到方法'didInsertElement'中的recordingFact对象不是null。我看到了身份。

<script type="text/x-handlebars" data-template-name="alerts/alert">
    <div class="panel panel-primary">
        <div class="panel-heading">
            <h3 class="panel-title"> 
                <i class="glyphicon glyphicon-flash"></i>
                Alert
            </h3>
        </div>
        <div class="panel-body">
                {{alert-chart recordingFact=model.recordingFact}}
        </div>
    </div>
</script>

App.AlertChartComponent = Ember.Component.extend({
    recordingFact: null,
    didInsertElement: function(){

        var recordingFact = this.get('recordingFact'); 
        // if I do some code with promise like .then(function(response){...}) 
        // I get the error recordingFact has no method then
        //

        var data = recordingFact.get('recordsString');  // I get undefined 

    }
})

它对我有用，你确定你传递了一个承诺，或者你确定该模型上存在该属性吗？

您可以将其注销以查看

<div class="panel-body">
   {{log model.recordingFact}}
   {{alert-chart recordingFact=model.recordingFact}}
</div>

组件承诺不起作用
