模型挂钩，this.store.find（）失败

Question

我这样做：

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

但总是得到一个错误信息：

Error while processing route: accounts Cannot read property 'map' of undefined TypeError: Cannot read property 'map' of undefined 
    at s.map (http://localhost/public/bower_components/ember/ember.min.js:10:14956)

如果我摆脱了查询参数的，即：

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，以防发生错误，但无法解决问题。

任何想法有什么不对？

你的查询/查找所有响应的json响应应该是一个集合。在你的情况下，它应该看起来像这样：

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

此外，你应该在传入类型时使用小写。

this.store.find('account');
