Django dateutil ISO 8601沒有'讀取'屬性錯誤

Question

我在Django視圖中將日期時間轉換爲ISO 8601以推送至Facebook頁面事件。我曾嘗試datetime.strptime但following best advice我選擇到：

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

EVENTDATE看起來像這樣在控制檯當我打印2013-06-18 02:50:00但它不會再得到任何之前，我：

什麼這可以嗎？謝謝

Answer 1

我可以重現該錯誤信息是這樣的：

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' 

所以在此基礎上好像eventdate可能已經是datetime.datetime對象。如果是這樣，也沒有必要調用

date_iso = dateutil.parser.parse(eventdate) 

要將其轉換爲ISO8601格式的string，使用

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

錯誤很明顯：你傳入一個datetime對象，實際上parse需要一個字符串。
