Django dateutil ISO 8601 没有“读取”属性错误答案

【问题标题】：Django dateutil ISO 8601 no 'read' attribute errorDjango dateutil ISO 8601 没有“读取”属性错误
【发布时间】：2013-06-12 23:37:53
【问题描述】：

我在 Django 视图中将日期时间转换为 ISO 8601 以推送到 Facebook 页面事件。我试过datetime.strptime 但following best advice 我选择了：

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

当我打印 2013-06-18 02:50:00 时，控制台中的事件日期看起来像这样，但在我得到之前它没有得到任何进一步的信息：

这可能是什么？谢谢

【解决方案1】：

我可以像这样重现错误消息：

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'

因此，在此基础上，似乎eventdate 可能已经是一个datetime.datetime 对象。如果有，就不用打电话了

date_iso = dateutil.parser.parse(eventdate)

要将其转换为 ISO8601 格式的string，请使用

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

错误很明显：您传入的是 datetime 对象，而实际上 parse 需要一个字符串。
