javascript - Ember.js Railscast #410 未定义不是函数 TypeError : at RandomRaffle. EntriesRoute.Ember.Route.extend.setupController

Question

我正在关注 Ember.js Railscast 第 410 集。当我更改 router.js 文件时

RandomRaffle.EntriesRoute = Ember.Route.extend({
  setupController: function (controller) {
    controller.set('content', []);
  }

});

到此

RandomRaffle.EntriesRoute = Ember.Route.extend({
  setupController: function (controller) {
    controller.set('content', RandomRaffle.Entry.find());
  }

});

我收到错误:

处理路由时出错:未定义的条目不是函数类型错误:未定义不是 RandomRaffle.EntriesRoute.Ember.Route.extend.setupController 的函数

我的 models/entry.js 文件包含:

RandomRaffle.Entry = DS.Model.extend({
  name: DS.attr('string'),
  winner: DS.attr('boolean')
});

我的controllers/entries_controller.js包含:

RandomRaffle.EntriesController = Ember.ArrayController.extend({
// newEntryName: "",

  actions: {

    addEntry: function () {
      RandomRaffle.Entry.createRecord({name: this.get('newEntryName')});
      this.set('newEntryName', "");
    },

    drawWinner: function () {
      this.setEach('highlight', false);
      var pool = this.rejectBy('winner');
      if (pool.length > 0){
        var entry = pool[Math.floor(Math.random() * pool.length)];
        entry.set('winner', true);
        entry.set('highlight', true);
        this.get('store').commit();
      }
    }

  }
});

javascripts/store.js

RandomRaffle.Store = DS.Store.extend({});

// Override the default adapter with the `DS.ActiveModelAdapter` which
// is built to work nicely with the ActiveModel::Serializers gem.
RandomRaffle.ApplicationAdapter = DS.ActiveModelAdapter.extend({});

我错过了什么？

如果您的store已正确定义，您应该创建一个 model route 中的函数，类似于:

RandomRaffle.EntriesRoute = Ember.Route.extend({
  model: function() {
       return RandomRaffle.Entry.find(); 

       // This is deprecated. Latest versions of ember-data use the following:
       // return this.store.find('entry');

       // this method returns a promise that will
       // carry the model data once it resolves
       // This is internally passed as a param of `setupController`
  },
  setupController: function (controller, model) {

       controller.set('content', model);
       // this is the same as the default implementation, so if you're *NOT* doing
       // anything different than this, get rid of `setupController` altogether

       // the `model` param, is the return of the `model` function just above. 
       // It is returned a `promise` rather than data, and will be made 
       // available once the promise is resolved, materializing the records 

       // the param doesn't have to be called `model`, but the 
       // function above *HAS* to be named `model` 
  }

});

我不是 100% 确定，但我相信可能会发生错误，因为您在调用 RandomRaffle.Entry.find() 时应该是 this.store.find('条目')
