Question

我在Django（1.3，python 2.7）中使用Suds时遇到了一些问题。

当我在脚本中使用suds检索数据时，它可以工作; 但是如果我在django视图中输入** exactyle相同的**代码，我会收到错误：

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

我的代码很简单：

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

完整的追溯：

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

我不知道为什么我使用Django会出现此错误。

我认为这个人的问题是同一个问题：AttributeError: 'NoneType' object has no attribute 'str' in suds

所以，如果有人有想法，

感谢。

Answer 1

虫子在泡沫中，但通常是沉默的。但是，使用django-debug-toolbar时会出现错误，因为日志记录面板会显示已记录的所有消息。

我已经创建了一个补丁版的suds来解决这个问题：https://github.com/bradleyayers/suds-htj

Answer 2

您的错误在这里：

s = '%s [%s] %s: %s' % (dt, record.name, record.levelname, record.getMessage())

其中一个变量是None，我最初的怀疑是dt。

Django和Suds：'NoneType'对象在suds中没有属性'str'
