骨干牵线木偶中的视图如何知道与哪个模型相关联？

Question

https://github.com/marionettejs/backbone.marionette/blob/master/docs/marionette.view.md

在这个例子中：

<script id="my-template" type="text/html"> 
    I think that <%= showMessage() %> 
</script> 

MyView = Backbone.Marionette.ItemView.extend({ 
    template: "#my-template", 

    templateHelpers: { 
    showMessage: function(){ 
     return this.name + " is the coolest!" 
    } 
    } 

}); 

model = new Backbone.Model({name: "Backbone.Marionette"}); 
view = new MyView(); 
view.render(); //=> "I think that Backbone.Marionette is the coolest!"; 

我试图分析这个代码，并根据我的骨干的了解，你必须指定模型视图与相关。我尝试了解Marionette的观点，并且我不知道文档的哪一部分，或者在这个示例中显示了该视图如何知道this引用了新创建的模型。或者这只是一个错字？

Answer 1

该示例中存在错误。它应该显示这个：

model = new Backbone.Model({name: "Backbone.Marionette"}); 

view = new MyView({ 
    model: model 
}); 

view.render(); //=> "I think that Backbone.Marionette is the coolest!"; 

我会更新的文档来解决这个
