爲什麼在此MarionetteJS複合視圖中未顯示元信息？

Question

我收到了一個帶有MarionetteJS的CompositeView加載元信息的意外行爲。從服務器端的JSON的樣子：

 
{ 
    "meta": { 
     "total": 2 
    }, 
    "movies": [ 
     { 
      "category": "Action", 
      "description": "Another story goes ....", 
      "id": 1, 
      "stars": "4.0", 
      "title": "My test movie" 
     }, 
     { 
      "category": "Action", 
      "description": "the story goes....", 
      "id": 2, 
      "stars": null, 
      "title": "my second movie" 
     } 
    ] 
} 

我用一個骨幹集合設置像元信息：

 
MA.Collections.Movies = Backbone.Collection.extend({ 
    url: '/api/movies.json', 
    parse: function(data) { 
    this.meta = new MA.Models.MetaMovie(data.meta); 
    return data.movies; 
    } 
}); 

MA.addInitializer(function() { 
    MA.Collections.Movies.model = MA.Models.Movie; 
}) 

但是，當我嘗試從CompositeView中訪問此元變量，收集被正確初始化，而元信息似乎丟失了。任何想法如何將這個元信息提供給CompositeView的模型？

PS控制檯輸出看起來像：

安裝程序獲取並使用它來meta.total的值設置直接到你的metaMovie模型實例

movies.js回調：

MA.addInitializer(function(){ 
    var self = this; 
    var metaMovie = new MA.Models.MetaMovie({total: 1}); 

    MA.collections.movies = new MA.Collections.Movies(); 
    MA.composites.movies = new MA.Views.Composites.Movies({ 
    itemView: MA.Views.Items.Movie, 
    model: metaMovie, 
    collection: MA.collections.movies 
    }); 
    var p = MA.collections.movies.fetch(); 

    // see http://api.jquery.com/jQuery.ajax/ for details 
    p.done(function(data) { 
    self.metaMovie.set({total: data.total}); 
    }); 
});
