嗨，我在rails中使用ruby 1.9和rails 3.2.1
启动预订应用程序我的某个操作似乎因错误而失败
undefined method `reservefunctionrooms' for #<Reservation:0xb637f24c>
我不知道它错在哪里，但我认为我做的一切都是正确的
我的route.rb
resources :reservations do
resources :reservefunctionrooms
end
我的控制器
class ReservefunctionroomsController < ApplicationController
# GET /reservefunctionrooms
# GET /reservefunctionrooms.json
def index
#@reservefunctionrooms = Reservefunctionroom.all
redirect_to Reservation.find(params[:reservation_id])

end
end

end
我的模型reservefunctionroom.rb

我的观点resevefunctionroom / new.html.erb

您需要将has_many :reservefunctionrooms添加到reservation模型中。
