好吧,我在 Active Admin 中创建了一个名为“最新客房”的自定义页面,它显示了一个包含当前日期酒店客房的表格。
现在我想在这个自定义页面中添加一个表单,我可以在其中选择日期。我设法通过以下方式使表单与 Datepicker 一起出现:
<%= semantic_form_for :newest_rooms, :builder => ActiveAdmin::FormBuilder do |f|
f.inputs do
f.input :Datum, :as => :datepicker
end
f.buttons
end %>
但不知道如何将其发送到正确的控制器和方法 HotelRoom.newest_rooms
我希望有人可以向我解释如何做到这一点。我添加了以下代码:
latest_room.rb
ActiveAdmin.register_page "Newest Rooms" do
menu :label => "Newest Rooms"
content do
render "newest_rooms"
end
end
_newest_room.html.erb
<% @cities = Hotel.cities %>
<%= semantic_form_for :newest_rooms, :builder => ActiveAdmin::FormBuilder do |f|
f.inputs do
f.input :Datum, :as => :datepicker
end
f.buttons
end %>
<ul class="room_list">
<% @cities.each do |c| %>
<li>
<table>
<tr>
<td>
<h2><%= c.City %></h2>
</td>
</tr>
<tr class="room_column">
<td>Hotel</td>
<td>Free Rooms</td>
<td>BN-Price</td>
<td>Old Price</td>
</tr>
<% @rooms = HotelRoom.newest_rooms(c.City) %>
<% @rooms.each do |r| %>
<tr>
<td><%= r.hotel.Hotelname %></td>
<td><%= r.FreeRooms %></td>
<td><b><%= r.Price %>€</b></td>
<td><%= r.OldPrice %>€</td>
</tr>
<%end%>
</table>
</li>
<% end %>
</ul>
hotel_room.rb
class HotelRoom < ActiveRecord::Base
validates :title, :presence => true
self.table_name = "hotel_room"
belongs_to :hotel, :foreign_key => 'H_ID'
accepts_nested_attributes_for :hotel
def to_key
[self.ID]
end
def self.newest_rooms(city)
HotelRoom.find(:all, :joins => :hotel, :conditions => ["hotel.City = ? and hotel_room.Date = ?", city, Date.today])
end
end
