Django dateutil ISO 8601没有'读取'属性错误

Question

我在Django视图中将日期时间转换为ISO 8601以推送至Facebook页面事件。我曾尝试datetime.strptime但following best advice我选择到：

eventdate = event.date 
    print eventdate 
    date_iso = dateutil.parser.parse(eventdate) 

EVENTDATE看起来像这样在控制台当我打印2013-06-18 02:50:00但它不会再得到任何之前，我：

什么这可以吗？谢谢

Answer 1

我可以重现该错误信息是这样的：

In [58]: import datetime as DT 

In [59]: eventdate = DT.datetime(2013, 6, 18, 2, 50) 
In [60]: print(eventdate) 
2013-06-18 02:50:00 

In [61]: import dateutil.parser as parser 
In [62]: parser.parse(eventdate) 
AttributeError: 'datetime.datetime' object has no attribute 'read' 

所以在此基础上好像eventdate可能已经是datetime.datetime对象。如果是这样，也没有必要调用

date_iso = dateutil.parser.parse(eventdate) 

要将其转换为ISO8601格式的string，使用

In [66]: eventdate.isoformat() 
Out[66]: '2013-06-18T02:50:00'

错误很明显：你传入一个datetime对象，实际上parse需要一个字符串。
