Rails - 获取当前周和月份的开始和结束日期 [英] Rails - Get the current week's and month's start and end dates

问题描述

我刚刚在轨道上的红宝石被困在日期。我使用 Time.now 来获取当前时间。现在我想找出当前周和当前月份的srart和结束日期。例如：

如果 Time.now 返回我 -

  2012-08-13 15:25:35 +0530 
  

然后，本周的开始和结束日期是：

  2012-08-12  -  2012-08-18 
  

然后当月的开始和结束日期是：

  2012--08-01  -  2012-08-31 
  

我使用代码实现相同：

  Time.now.wday 
 => ; 1 
 
 Time.now  -  1.day 
 => 2012-08-12 15:31:44 +0530 
 
 Time.now + 5.day 
 => 2012-08-19 15:32:38 +0530 
  

等等..但是我没有找到这是一个方便的方法。我确定Ruby on Rails确实有更好的解决方案。任何人都可以提出相同的想法。

解决方案

而不是使用Time.now

使用以下代码来解决问题

  d = Date.today 
 
 d.at_beginning_of_week 
 #Mon，2012年8月13日
 d.at_beginning_of_week.strftime 
＃2012-08-13
 d.at_beginning_of_week.strftime（％d ）
＃13 - >打印日期。 
  

同样，您可以在日期类

I am new to ruby on rails and got stuck in dates. I used Time.now to get the current time. Now I want to find out the srart and end dates for the current week and current month. For instance:

If Time.now returns me -

2012-08-13 15:25:35 +0530

Then the start and end dates for the current week are:

2012-08-12 - 2012-08-18

Then the start and end dates for the current month are:

2012--08-01 - 2012-08-31

I am implementing the same using the code:

Time.now.wday   
 => 1 

Time.now - 1.day
=> 2012-08-12 15:31:44 +0530 

Time.now + 5.day
 => 2012-08-19 15:32:38 +0530

and so on.. But I dont find it a convenient way to do this. Iam sure Ruby on Rails does hold a better solution. Can anyone suggest to figure out the same..

解决方案

Instead of using Time.now

Use the following code to get your queries solved

d = Date.today

d.at_beginning_of_week
#Mon, 13 Aug 2012
d.at_beginning_of_week.strftime
#"2012-08-13"
d.at_beginning_of_week.strftime("%d")
#"13" -> To print the date.

Similarly you can find multiple methods in the Date Class
