木偶ItemView控件如何在变化的重新渲染模式 [英] Marionette ItemView how to re-render model on change

问题描述

我使用的把手模板引擎。结果
所以，我有型号：

I'm using Handlebars template engine.
so, I have Model:

Backbone.Model.extend({
        urlRoot: Config.urls.getClient,
        defaults: {
            contract:"",
            contractDate:"",
            companyTitle:"",
            contacts:[],
            tariff: new Tariff(),
            tariffs: [],
            remain:0,
            licenses:0,
            edo:""
        },
        initialize:function(){
            this.fetch();
        }
    });

然后木偶ItemView控件：

then Marionette ItemView:

Marionette.ItemView.extend({
        template : templates.client,
        initialize: function () {
            this.model.on('change', this.render, this);
        },
        onRender: function () {
            console.log(this.model.toJSON());
         }      
    });

然后我把一切为：

and then I call everything as:

new View({
    model : new Model({id:id})
        })

和，它立刻就出来了我的一个观点，这是很酷。
但该模型获取数据后，它的触发改变，所以我在控制台序列化的模型中看到两次，我看到了第一次空模型，然后进行填充的。

and, it's immediately render a view for me and this is cool. But after the model fetched data it's trigger "change", so I see in console serialised model twice, and I see for first time empty model and then filled one.

不过，该视图不会被更新。

But, the view is NOT updated.

我怎样才能解决这个问题？

How I can fix it?

P.S。我明白了，我可以呼吁取做回调渲染方法。但是我还需要进行进一步操作，当用户将改变模式。

P.S. I understand, that I can call a render method on fetch done callback. But I also need it for further actions, when user will change model.

推荐答案

其实，骨干网和木偶有足够的智慧来做到这一点。结果
问题是模板和数据，我发现它<一个href=\"http://stackoverflow.com/questions/16793422/backbone-marionette-itemview-not-rendering-on-model-change?rq=1\">another问题。所以，我重新检查一切，得到的结果。

Actually, Backbone and Marionette are smart enough to do it.
Problem was in template and data as I found it another question. So, I re-checked everything and got result.
