Rails DateTime.now without Time
提问by Mike
I need to use DateTime.now to grab the current date, and "strip off" the time.
我需要使用 DateTime.now 来获取当前日期，并“剥离”时间。
For example, this shows what I don'twant: DateTime.now => Sat, 19 Nov 2011 18:54:13 UTC +00:00
例如，这显示了我不想要的内容：DateTime.now => Sat, 19 Nov 2011 18:54:13 UTC +00:00
This shows what I dowant: DateTime.now.some_operation => 2011-11-06 00:00:00 UTC
这说明什么，我做想要的：DateTime.now.some_operation => 2011-11-06 00:00:00 UTC
