Javascript 主干模型->；收集->；型号->；更新-不触发根模型上的更改

我正在吃这个

ServerInfoModel = Backbone.RelationalModel.extend({     
    relations: [
        {
            type: Backbone.HasMany,
            key: 'data',
            relatedModel: 'Data',
            collectionType: 'DataCollection',
            reverseRelation: {
                key: 'id',
                includeInJSON: 'id'
            }
        }
    ]
})
Data = Backbone.RelationalModel.extend({
});

DataCollection = Backbone.Collection.extend({
    model: Data
});

现在我有了一个与ServerInfoModel关联的视图。 如果我更改了该集合中模型数据的值，“更改”不会在ServerInfoModel上触发，而是仅在DataCollection上触发

---

如何将“更改”事件从数据收集传递到ServerInfoModel？

我知道了如何做，只需聆听“数据”更改并进一步触发“更改”

ServerInfoModel = Backbone.BaseRelationalModel.extend({
url: function () {
    return "/examples/serverInfo.json"
},
setup: function () {
    var self= this;
    this.get('data').on('change', function () {
        self.trigger("change");
    });
},

relations: [
    {
        type: Backbone.HasMany,
        key: 'data',
        relatedModel: 'Data',
        collectionType: 'DataCollection',
        reverseRelation: {
            key: 'id',
            includeInJSON: 'id'
        }
    }
]
});

Data = Backbone.BaseRelationalModel.extend({ 
});

DataCollection = Backbone.Collection.extend({
  model: Data
});
