Parse a date in rails
提问by Sachin Prasad
I have a date (Which is actually parsed from a PDF) and it could be any of the following format:
我有一个日期(实际上是从 PDF 解析出来的),它可以是以下任何一种格式:
MM/DD/YYYY
MM/DD/YY
M/D/YY
October 15, 2007
Oct 15, 2007
Is there any gem or function available in rails or ruby to parse my date? Or I need to parse it using regex?
rails 或 ruby 中是否有可用的 gem 或函数来解析我的日期?或者我需要使用正则表达式解析它?
BTW I'm using ruby on rails 3.2.
顺便说一句,我在 rails 3.2 上使用 ruby。

You can try Date.parse(date_string).
你可以试试Date.parse(date_string)。
You might also use Date#strptimeif you need a specific format:
Date#strptime如果您需要特定格式,您也可以使用:
> Date.strptime("10/15/2013", "%m/%d/%Y")
=> Tue, 15 Oct 2013
For a general solution:
对于一般解决方案:
format_str = "%m/%d/" + (date_str =~ /\d{4}/ ? "%Y" : "%y")
date = Date.parse(date_str) rescue Date.strptime(date_str, format_str)

I find the chronic gem very easy to use for time parsing and it should work for you. i tried the examples you gave.
我发现慢性宝石非常易于用于时间解析,它应该适合您。我试过你给出的例子。
