我的数据库中的日期如下所示：2012-07-23
我试图看看日期是否超过7天前且不到14天前,或者看看日期是否大于14天前,但我没有运气..
这是我的代码：
def progress_report_status_check(date)
progress_date = date.to_date
seven_days = 7.days.ago.to_date
fourteen_days = 14.days.ago.to_date
if seven_days > (progress_date - 7.days.ago.to_date) or (progress_date - 14.days.ago.to_date) < fourteen_days
"due"
elsif (progress_date - 14.days.ago.to_date) > fourteen_days
"overdue"
end
end
解决方法
def progress_report_status_check(progress_date) # Pass in a date
if (progress_date < Date.now-14.days)
"overdue"
elsif (progress_date < Date.now-7.days)
"due"
end
end
或(不太可读)
def progress_report_status_check(progress_date) # Pass in a date (progress_date < Date.now-14.days) ? "overdue" : ((progress_date < Date.now-7.days) ? "due" : "") : "" end end
根据您的使用情况,您可能希望创建命名范围,例如：
scope :overdue where(:progress_date < Date.now-14.days) scope :due where(:progress_date < Date.now-7.days)
def progress_report_status_check(progress_date) # Pass in a date self.overdue? ? "overdue" : self.due? ? : "due" : "" end end
