Rails：有没有得到最近的星期一到今天的Date对象？ [英] Rails: Is there away to get the Date object that is the closest Monday to today?

问题描述

我知道我可以做一些事情：

Date.tomorrow
Date.today

有没有像Date.nearest这样的东西：星期一？

解决方案

commercial 方法在Date对象上会让你这样做。

  Date.commercial（Date.today.year，1 + Date.today.cweek ，1）
  

如果您需要下一个或上一个星期一，以最接近的人为准，您可以执行以下操作： / p>

  Date.commercial（Date.today.year，Date.today.cwday.modulo（4）+ Date.today.cweek， 1）
  

我现在无法执行，所以原谅我，如果有语法错误。 / p>

Given a date, how do I find the nearest Monday in Rails?

I know I can do things like:

Date.tomorrow Date.today

Is there something like Date.nearest :monday ?

解决方案

The commercial method on the Date object will let you do this. This example will get you the next Monday.

Date.commercial(Date.today.year, 1+Date.today.cweek, 1)

If you need the next or previous Monday, whichever is closest, you can do:

Date.commercial(Date.today.year, Date.today.cwday.modulo(4)+Date.today.cweek, 1)

I can't execute this right now, so forgive me if there are syntax errors.
