餘燼：瞭解錯誤

這對我來說很難理解ember.js錯誤。我總是必須查看我的所有代碼並進行隨機更改，因爲我無法確定哪裏出錯。特別我有這種錯誤，修改（但保持在結構上是相同的）的peepcode例如：餘燼：瞭解錯誤

錯誤發生時，然後導航輸入這個地址（未導航） transport_documents/2。如果我瀏覽到這條道路，相反，錯誤的是不同的：第一運輸單據我打開就可以了，而導航到第二我得到 You can't call renderToBufferIfNeeded on a destroyed view

是灰燼太年輕，實施錯誤處理，可以使一個對開發人員有意義，還是有一些方法可以更輕鬆地調試我的代碼？

我知道了'debugger'命令 –

您可以添加您的視圖模板內造成的？ – MilkyWayJoe

完成。添加了我的模板和路由器。我沒有查看代碼 –

有一對夫婦調試器，如Chrome擴展：

ember inspector和ember extension。但是他們無法工作，因爲燼寶正在發展得比這些插件更快。

的重新渲染錯誤是由outlet錯誤週期
