I am trying to compare dates for an app in rails. I have tried this link Comparing dates in rails. But this is not what I want, suppose I have a filter according to dates, then I am doing

<% jobs = @user.jobs.where(:curr_date => (Date.today))%>

Here, curr_date is a "date" attribute chosen by me.

This code works for entries which have today's date, but if I want all entries which have date between today and a week before, what should I do?

Thanx! :)

你可以简单地使用

jobs = @user.jobs.where(:curr_date => (DateTime.now..1.week.ago))

更新到DateTime.now或者也可以使用Date.today.to_time，否则比较 aDate和 a会出错Time

我认为这样的事情应该有效：

<% jobs = @user.jobs.where(['curr_date < ? AND curr_date > ?', Date.today, 1.week.ago])) %>

compare_date_1 <=> comparison_date_2 可能对您有用，它会相应地返回-1,1,0，您可以填充它们......

没有在控制台中尝试过，但我认为它应该可以工作：

# You need to implement the #week_before method
@user.jobs.where(:curr_date => (Date.week_before..Date.today))
