You don't need to save it in a variable.

不需要将它保存在变量中。

Time.now.strftime("%Y-%m-%d")  # 2013-01-08

#5

Needs the Time module for Time.parse and ActiveSupport for Integer#ordinalize:

需要时间模块。解析和ActiveSupport的整数#序化:

require 'time'
require 'active_support'

input = '2010-06-14 19:01:00 UTC'
t = Time.parse(input)
date = "%s %s, %d" % [t.strftime("%B"), t.day.ordinalize, t.year]
# => "June 14th, 2010"

Just the other day there was a similar question. In my answer how do I get name of the month in ruby on Rails? I showed how you can add a custom to_s definition in your config/environment.rb file.

就在前几天，有一个类似的问题。在我的回答中，我如何在ruby on Rails中获得本月的名称?我展示了如何在配置/环境中添加定制的to_s定义。rb文件。

ActiveSupport::CoreExtensions::Time::Conversions::DATE_FORMATS.merge!(
 :my_own_long_date_format => "%B %d, %Y")

Now you can call Time.now.to_s(:my_own_long_date_format) from any view to get:

现在可以从任何视图调用Time.now.to_s(:my_own_long_date_format)来获取:
