私が書いていないバックボーンアプリを編集しようとしています。私の目標は、 'search：success'がトリガされたときに、ファセットビューのコレクションをアプリビューからリセットすることです。app.jsからの更新ビュー
この最初のファイルはapp.jsファイルです：

var Facet = require('./models/facet');
var FacetView = require('./views/facets');

var PartmatchView = require('./views/partmatch');

var SearchView = require('./views/search');
var SelectedFacetsView = require('./views/selectedFacets');

var TotalView = require('./views/pageResults');
var fileTypes,

すでにレンダリングされている場合は、現在のコレクションのfileTypesViewを更新できます。私はfacets.jsビューを使用する3つのファセットビューが存在するので、これで苦労しました。だから私はそれがレンダリングされていると、ビューを呼び出すことができ、新しいデータでコレクションをリセットするトリガを主に思っています。
