Django和Suds：'NoneType'對象在泡沫中沒有屬性'str'

在Django（1.3，python 2.7）中使用Suds時遇到了一些問題。Django和Suds：'NoneType'對象在泡沫中沒有屬性'str'

當我在腳本中使用泡沫檢索數據時，它可以工作; 但如果我把** exactyle同**代碼在Django的看法，我得到的錯誤：

'NoneType' object has no attribute 'str' in suds

我的代碼很簡單：

client = Client(WSDL_URL, location=LOCATION_URL, cache=None) 
client.service.getRooms({'type':'AVAILABLE'})

以及完整回溯：

    client.service.getRooms({'type':'AVAILABLE'})

AttributeError: 'NoneType' object has no attribute 'str'

我不知道爲什麼我用Django得到這個錯誤。

我認爲這是同樣的問題，這個人：AttributeError: 'NoneType' object has no attribute 'str' in suds

因此，如果任何人有一個想法，

感謝。
