我有嵌套模型定义如下:
AS.ExerciseRun = DS.Model.extend({
'name' : DS.attr('string'),
'exercise' : DS.belongsTo('exercise')
});
AS.Exercise = DS.Model.extend({
'name' : DS.attr('string'),
'engagement' : DS.belongsTo('engagement')
});
AS.Engagement = DS.Model.extend({
'name' : DS.attr('string')
});
我需要在我的一个名为“AnalyticsRunsIndex”的数组控制器中使用“ExerciseRun”模型。我将它添加到arrayController的needs属性中。我现在有点困,因为我不确定如何通过AnalyticsRunsIndexRoute将数据加载到我的ExerciseRunController中。我的路线代码是:
AS.AnalyticsRunsIndexRoute = Ember.Route.extend({
exerciseRunId: null,
model: function () {
.....
},
setupController: function (controller, model) {
this._super(controller, model);
controller.set('exerciseRunId', this.get('exerciseRunId'));
this.controllerFor('analyticsTemplates').set('model', controller.get('store').find('analyticsTemplate'));
//TRIED AND FAILED!!!
//this returns a rejected promise with error TypeError: payload[prop].map is not a function
//this.controllerFor('exerciseRun').set('model', controller.get('store').find('exerciseRun', {'id': this.get('exerciseRunId')}));
//controller.get('store').find('exerciseRun', {'id': this.get('exerciseRunId')}).then(function(data){
// this.controllerFor('exerciseRun').set('content',data);
//});
//controller.get('store').find('exerciseRun', {'id': this.get('exerciseRunId')}).then(function(data){
// controller.get('store').pushPayload('exerciseRun', data);
// controller.set('exerciseRun',data);
//});
//set exerciseRun details to the arrayController from any one record
/*
var store = controller.get('store');
$.ajax({
type: "GET",
url: AS.baseURL + "exerciseRuns",
data: {"id": this.get('exerciseRunId')},
success: $.proxy(function (data) {
//controller.set('exerciseRunData', data);
}, this),
dataType: "JSON"
});
*/
}
});
如何将此数据传输到适当的控制器?我试过简单地将属性设置为ArrayController的实例,但这也不起作用。任何帮助都感激不尽。感谢

我认为在你的setupController
钩子里,你应该能够做到这样的事情:
// Get the controller outside of the promise.
// Inside the promise 'this' points to something different.
var exerciseRunController = this.controllerFor('exerciseRun');
controller.get('store').find('exerciseRun', {'id': this.get('exerciseRunId')}).then(function(data){
exerciseRunController.set('content',data);
});
