模型掛鉤，this.store.find（）失敗

Question

我這樣做：

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

但總是得到一個錯誤信息：

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)

e.invoke ember.min.js:11

t.end ember.min.js:11 
(anonymous function) 

如果我擺脫了查詢參數的，即：

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

然後一切正常。我使用的是ember 1.6.0和ember-data 1.0.0-beta8。我已經嘗試了幾個不同的版本，以防發生錯誤，但無法解決問題。

任何想法有什麼不對？

Answer 1

你的查詢/查找所有響應的json響應應該是一個集合。在你的情況下，它應該看起來像這樣：

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

此外，你應該在傳入類型時使用小寫。

this.store.find('account');
