Rails日期格式（匹配YYYY-MM-DD HH-MM-SS）

Question

When I do this:

DateTime.now.to_s

I get: 2015-07-31T22:22:05+02:00

But I need it in this format:

2015-07-31 22:22:05

How can I format it this way?

Answer 1

Since this is a common thing to want, there is a shorthand method to do this.

DateTime.now.to_s(:db)     #=> 2015-07-31 22:22:05

Answer 2

DateTime.now.strftime("%Y-%m-%d %I:%M:%S")

DateTime strftime方法

Answer 3

You can use strftime function for formatting your dates

DateTime.now.strftime('%Y-%m-%d %I:%M:%S')
