Question

我这样做：

App.AccountsRoute = Ember.Route.extend({
  model: function() {
    return this.store.find('Account', {company: 'Blah'});
  }
});

但始终收到错误消息：

Error while processing route: accounts Cannot read property 'map' of undefined TypeError: Cannot read property 'map' of undefined

如果我摆脱了查询参数，那就是：

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

然后一切正常。我使用的是ember 1.6.0和ember-data 1.0.0-beta8。我已经尝试了几个不同的版本，以防它出现问题，但无法解决问题。

任何想法有什么不对？

来自查询/查找所有响应的json响应应该是一个集合。在你的情况下，它应该是这样的：

{
  accounts:[
    {
       id:1,
       company:'Blah'
    },
    {
       id:2,
       company:'Blah'
    }
    ...
  ]
}

另外，传入类型时应使用小写字母。

this.store.find('account');

在模型钩子中，this.store.find（）失败
