Ruby on rails 在where类中使用日期范围

1。上下文

对于预订表，我正在尝试获取选定日期的所有不可用房间

我可以通过以下方式获得所有已预订的房间：

@unavailable_rooms = Room.joins(:reservations).where(reservations: {hotel: hotel})

但目前只返回：

[]

4。代码

酒店管理主任

def rooms_availability
  hotel = Hotel.includes(:rooms).find(params[:id])
  arrival = Date.parse room_params[:arrival]
  departure = Date.parse room_params[:departure]
  time_span = arrival..departure
  @unavailable_rooms = Room.joins(:reservations).where(reservations: {hotel: hotel}).where("reservations.arrival <= ? AND ? < reservations.departure", arrival, departure).distinct
  hotel_cats = hotel.room_categories
  hotel_accos = Room.where(room_category: hotel_cats)
  @rooms = hotel_accos - @unavailable_rooms
  authorize @rooms
  respond_to do |format|
    format.js
  end
end

def房间的可用性
hotel=酒店。包括（：房间）。查找（参数[：id]）
到达=日期。解析房间参数[：到达]
出发=日期。解析房间参数[：出发]
时间=到达..离开
@不可用的房间=房间。加入（：预订）。哪里（预订：{hotel:hotel}）。哪里（“预订。到达
room1
：


2019/11/24
小于或等于
2019/11/24
2019/11/26
不低于
2019/11/25
因此，room1将与给定的查询不匹配

room2
：


2019/11/24
不小于或等于
2019/11/25
2019/11/26
不小于
2019/11/26
（相同）
因此，room2将与给定的查询不匹配

代码中没有问题。应用的筛选器没有记录
