ChaplinJS收集同步问题

Question

所以我有一个集合我在应用程序开始处获取，像这样

module.exports = class Application extends Chaplin.Application
  start: ->
  #   # You can fetch some data here and start app
  #   # (by calling `super`) after that.
    Chaplin.mediator.styleCollection.fetch().then super

在home控制器接管并将用户带到相应的页面后，如下所示

module.exports = class HomeController extends Controller
  beforeAction: ->
    super
    @reuse 'header', HeaderView, region: 'header'
    @reuse 'nav', NavView, region: 'nav'
    @reuse 'price', PriceView, region: 'price'
    @reuse 'frame', FrameView, region: 'frame'
  piece: ->
    @view = new PieceView
      region: 'main'
      nextPage: "style"
    @subscribeEvent "click:continue-btn", ()->
      @redirectTo {url:"style"}
      @publishEvent "update:progress", 25
    , @

现在，当我通过我的HomeController到达PieceView时，我期望卓别林.mediator. stylecollection应该已经同步了，但是在重新加载期间几次显然集合还没有准备好。所以我放了一些控制台。下面是我看到的

console.log Chaplin.mediator.styleCollection输出(目前一切正常)

StyleCollection
_byId: Object
_events: Object
_previousSync: "syncing"
_syncState: "synced"
escape: function (value) {
length: 3
models: Array[3]
safe: function (value) {
__proto__: ctor

console.log卓别林.mediator. stylecollection . tojson()(这是事情发生的地方)

Array[0] <<<< the collection has nothing in it. I first thought the collection could still be syncing but that is not the case because the previous log showd _syncState: "synced"

任何想法吗?

好吧，这是一个愚蠢的修复。

在应用程序代码中，我做了以下操作

Chaplin.mediator.styleCollection.fetch()。Then => super
