主干对象渲染没有方法应用于 - 与问题绑定 [英] Backbone Object render has no method apply - issue with bind

问题描述

所以我在我的APPVIEW这样

So I'm doing this in my AppView

var flowerModel = new app.DataModel({title: "flower", values: ["tulip","rose","dandelion"], dataToShow:["tulip", "rose", "dandelion"], data: data});
    var timelineModel = new app.TimeChartModel({data: flowerModel.getDisplayedData(), titlesToShow: flowerModel.get('dataToShow')});


    tableCollection.add(flowerModel);

    var timechart = d3.select("body").append("div").attr("class","timechart");

    this.centerView = new app.TimeChartView({model: flowerModel, el : timechart});
    this.rightView = new app.TableView({model: flowerModel});

在我TimeChartView init方法我做到这一点 -

In my TimeChartView init method I do this-

initialize: function(){
        this.model.bind('change','render');
            //other, irrelevant things

}

在我flowerModel我有这样的方法，当一个复选框被选中其中工程 -

and in my flowerModel I have this method, which works when a checkbox is ticked -

events: {
    'click .data-type' : 'collapseDatum',
    'click .show-datum' : 'addDatumToShow',
},

addDatumToShow: function(e){
        var test = $(this.$el).find(".datum-list").find(":checked");
        newDataToShow = [];
        _.each(test, function(value,key,list){
            var title = $(value).data("title");
            newDataToShow.push(title);
        });
        this.model.set("dataToShow", newDataToShow);
    },

发生在this.model.set（'dataToShow'，newDataToShow）错误。

The error happens on the this.model.set('dataToShow', newDataToShow).

我真的不知道为什么和如何调试将是有益的任何意见。我不认为我做任何疯狂，或不寻常的位置。

I'm really not sure why and any advice on how to debug would be helpful. I don't think I'm doing anything crazy, or unusual here.

推荐答案

试试这个：

flowerModel.bind('change:dataToShow', function() { 
    timelineModel.set('titlesToShow', flowerModel.get('dataToShow')); 
});

---

this.model.bind('change', this.render);
