ruby-on-rails - 如何仅根据日期和月份获取用户的生日

Question

我想要一个今天生日和即将到来的生日(明天)的成员列表。

In users.controller.rb
def birthday
   @birthday_users = User.all.order("created_at DESC").where(:birthday => Date.today)
end

def upcoming_birthday
   @upcoming_birthday_user = User.all.order("created_at DESC").where(:birthday => 1.days.from_now )
end

这些代码仅在日、月、年与今天相同时才有效。

例子:

用户 1 的生日 = 2018 年 10 月 3 日(显示在生日列表中)

用户 2 的生日 = 2000 年 10 月 3 日(未显示在生日列表中)

Answer 1

在用户模型中

PostgreSQL

scope :today_birthday, { where('EXTRACT(month FROM birthday) = ? AND EXTRACT(day FROM birthday) = ?', Date.today.month, Date.today.day).order("created_at DESC") }

scope :upcoming_birthday, { where('EXTRACT(month FROM birthday) = ? AND EXTRACT(day FROM birthday) = ?', 1.days.from_now.month, 1.days.from_now.day).order("created_at DESC") }

MySql

scope :today_birthday, { where('MONTH(birthday) = ? AND DAY(birthday) = ?', Date.today.month, Date.today.day).order("created_at DESC") }

scope :upcoming_birthday, { where('MONTH(birthday) = ? AND DAY(birthday) = ?', 1.days.from_now.month, 1.days.from_now.day).order("created_at DESC") }
