我在第一个带有 Node.JS 后端的 Ember.js 应用程序上收到以下错误：

Intermediate-transitioned into 'loading' ember-1.5.0.js:3521
Error while loading route: TypeError: Cannot set property 'store' of undefined

Transition #0: games: transition was aborted

以下 json 由/games 返回

{
  "games": [
    {
      "serverSeedHash": "5eb59053dcb5810322e367245f631a65589ddf7bbe950d2986a43a5f376312ef",
      "id": 2,
      "serverSeed": null,
      "table": [
        1
      ],
      "amountOfPlayers": 2,
      "prizePool": 39600
    }
  ],
  "tables": [
    {
      "id": 1,
      "minimumPlayers": 2,
      "maximumPlayers": 100,
      "cardPrice": 1000,
      "games": [
        2
      ]
    }
  ]
}

我完整的 Ember.js 应用程序.js如下所示：

window.App = Ember.Application.create({
    LOG_TRANSITIONS: true,
    LOG_TRANSITIONS_INTERNAL: true
});
App.Router.map(function () {
    this.route('games', { path: '/' });
});
App.Game = DS.Model.extend({
    serverSeedHash: DS.attr(),
    serverSeed: DS.attr(),
    amountOfPlayers: DS.attr(),
    prizePool: DS.attr(),
    table: DS.belongsTo('table')
});
App.Table = DS.Model.extend({
    minimumPlayers: DS.attr(),
    maximumPlayers: DS.attr(),
    games: DS.hasMany('game')
});

App.GamesRoute = Ember.Route.extend({
    model: function () {
        return this.store.find('game');
    }
});

有谁知道为什么我会收到错误？请注意，这是我第一次玩Ember.JS。在过去的几天里，我一直在打破我的困境。

在你的game模型中，你table定义为一个belongsTo关系，所以 Ember 期望它是单数的，你向它发送数组。将您的对象更改为此对象，它应该可以工作：

{
  "games": [
    {
      ...
      "table": 1,
      ...
    }
  ],
  "tables": [
    ...
  ]
}
