生日那天通知别人

Question

我想发送通知邮件给今天生日不是的人。  我用代码找出今天过生日的人......

控制器代码：

@people = Person.find(:all, :conditions => ["DAY(date) = ? AND MONTH(date) = ?", Date.today.day, Date.today.month])

现在，如何修改它以获得生日人以外的其他人？

Answer 1

@people = Person.where('DAY(date) <> ? OR MONTH(date) <> ?', Date.today.day, Date.today.month)

Answer 2

当然应该是：

@people = Person.where('DAY(date) <> ? AND MONTH(date) <> ?', Date.today.day, Date.today.month)

使用OR会将当天和当月其他日期的其他月份的人排除在外。

Answer 3

@people = Person.where("extract(month from date) != ? AND extract(day from date) != ?", Date.today.month, Date.today.day)
