骨干集合无法获取数据

Question

我试图在我的集合中获取数据，但我没有收到任何结果。

这是我的看法骨干

class Movieseat.Views.MovieseatsIndex extends Backbone.View 

    template: JST['movieseats/index'] 

    initialize: -> 
    @collection.on('reset', @render, this) 

    render: -> 
    $(@el).html(@template(movies: @collection)) 
    this 

我的骨干收集

class Movieseat.Collections.Movieseats extends Backbone.Collection 

    url: '/api/movies' 

我的骨干线路

class Movieseat.Routers.Movieseats extends Backbone.Router 

    routes: 
    '': 'index' 

    initialize: -> 
    @collection = new Movieseat.Collections.Movieseats() 
    @collection.fetch() 

    index: -> 
    view = new Movieseat.Views.MovieseatsIndex(collection: @collection) 
    $('#container').html(view.render().el) 

我的骨干模板

<ul id="movie-overview"> 

    <li><%= @movies.length %></li> 

</ul> 

这个长度输出0

当我走在我的控制台和做

movies = new Movieseat.Collections.Movieseats 

结果

Movieseats {length: 0, models: Array[0], _byId: Object, constructor: function, url: "/api/movies"…} 

检查长度

movies.length 

结果

0 

但是当我做

movies.fetch() 

它导致该

function() {done: function() {error: function() {fail: function() {getAllResponseHeaders: function() {getResponseHeader: function (key) {overrideMimeType: function (type) {pipe: function (/* fnDone,

我做了

movies.length 

而现在它输出的电影的数量

41 

因此，如果抓取工作在我的控制台中，为什么它不能在我的应用程序中工作？请注意，我已经有

initialize: -> 
    @collection.on('reset', @render, this) 

哪个应该重新显示集合。

Answer 1

通过我的骨干路由器文件更改获取命令我能解决这个问题

initialize: -> 
    @collection = new Movieseat.Collections.Movieseats() 
    @collection.fetch() 

要

initialize: -> 
    @collection = new Movieseat.Collections.Movieseats() 
    @collection.fetch({reset: true})
