Question

我刚升级到最新的ember.js。在那之后，我的应用程序开始失败。

这是Firebug输出：

DEBUG: -------------------------------
DEBUG: Ember      : 1.0.0
DEBUG: Ember Data : 1.0.0-beta.2
DEBUG: Handlebars : 1.0.0
DEBUG: jQuery     : 1.10.2

    return App.Clock.find();
TypeError: App.Clock.find is not a function 
    return App.Clock.find();
TypeError: App.Clock.createRecord is not a function

以下是相关代码：

App.ClocksRoute = Ember.Route.extend({
  model: function() {
    var locationService = UtilitiesHelper.LocationService.getInstance();
    locationService.getLocation(function(location) {
            App.Clock.createRecord({
                city: location.city,
                country: location.country,
                latitude: location.latitude,
                longitude: location.longitude,
                color: '#483D8B',
                order: -10
            });
        });

        return App.Clock.find();
    }
});

我无法弄清楚新版本中的变化。

在最新版本的Ember Data（Beta 2及更高版本）而不是App.Clock.find()中，您必须执行this.get('store').find('clock')。

请仔细阅读Ember Data Beta Transition documentation。第一部分介绍了find。

您还需要将createRecord更新为：

  this.get('store').createRecord('clock', {
     city: location.city,
     country: location.country,
     latitude: location.latitude,
     longitude: location.longitude,
     color: '#483D8B',
     order: -10
  });

虽然这些可能不是您将代码迁移到最新版本所需进行的唯一更改。这个post也可能会有所帮助。

最新的ember.js（1.0.0.0）无法识别“find”和“createRecord”
