未初始化的常量預訂

喜IM我做了一個靜態頁面，我的我的預訂應用程序的功能室都顯示，並且可以添加在的 reservation_function_room（線項目預訂functionroom）它提出了未初始化常量預訂時曾經我對<%= link_to "add functionrooms", reservation_pages_functionroom_path(@reservation) %>路線不能在此先感謝弄清楚什麼是錯非常感謝未初始化的常量預訂

頁面靜態頁面

class PagesController < ApplicationController 

    def functionroom 
    @reservation = Reservation.find(params[:reservation_id]) 
    @function_room = FunctionRoom.all 
    end 
end

functionroom.html.erb

<% if notice %> 
<p id = "notice"><%= notice%></p> 
<%end%> 

    <h1>functionRooms</h1> 
    <%@function_room.each do |functionroom|%> 
    <h3><%= functionroom.name%></h3> 
    <p><%= number_to_currency(functionroom.price)%></p> 
    <%= button_to 'add function room', 
reservation_reservation_function_room_path(:function_room_id => 
functionroom), :method => :post,:remote => true%> 
    <%end%>

reservation_contoller.rb

def index 
    @reservations = Reservation.all 
    end 

    def show 
    @reservation = Reservation.includes(:reservation_function_rooms => 
:function_room,:reservation_package => :package).find(params[:id]) 
    end

class ReservationFunctionRoomsController < InheritedResources::Base 
def show 
    @reservation_function_room = 
ReservationFunctionRoom.find(params[:id]) 
end 


def new 
    @reservation_function_room = ReservationFunctionRoom.new 
end 

def create 
    @reservation = Reservation.find(params[:reservation_id]) 
    function_room = FunctionRoom.find(params[:function_room_id]) 
    @reservation_function_room = 
@reservation.add_function_room(function_room.id) 

    if @reservation_function_room.save 
    redirect_to @reservation, :notice => "function room successfuly 
added" 
    end 
end 
end

沒有輸入完整的細節，我可以看到你的代碼中的一個巨大的錯誤。你在MODEL裏有這樣一行，你不能這樣做：'redirect_to @reservation ...' – Zheileman 2012-03-27 12:42:04

我已經嘗試刪除該行，甚至不使用add_functionromm方法，但它仍然是相同的答覆 – Led 2012-03-27 12:50:14

'uninitialized constant Reservations'告訴我，在你的代碼中的某處你可能有一個類型，並且試圖調用預留的類方法而不是保留（你的模型名稱）。我會在您的代碼中進行全球搜索以查找「預訂」，並查找您引用「預訂」而不是「預訂」的位置。 – 2012-03-27 13:11:33

我知道這已經4年了，但是我遇到了同樣的問題，我想我可能已經找到它來自哪裏。

你必須依賴「HAS_ONE：reservation_package」，並降低你的「資源：reservation_packages」

我認爲「S」現在的問題是：要麼做一個單一的資源或關係的has_many。那爲什麼他找不到它。這就是我如何解決我的問題。
