#<Reservation:0xb637f24c>的未定义方法` `reservefunctionrooms‘

Question

您好，我是rails新手，正在使用Ruby1.9和rails 3.2.1启动一个预订应用程序

我的一项操作似乎因错误而失败

undefined method `reservefunctionrooms' for #<Reservation:0xb637f24c>

我不知道哪里做错了，但我想我做的一切都是对的

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])
    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @reservefunctionrooms }
    end
  end

  # GET /reservefunctionrooms/1
  # GET /reservefunctionrooms/1.json
  def show
    #@reservefunctionroom = Reservefunctionroom.find(params[:id])
    redirect_to Reservation.find(params[:reservation_id])

    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @reservefunctionroom }
    end
  end

  # GET /reservefunctionrooms/new
  # GET /reservefunctionrooms/new.json
  def new
    #@reservefunctionroom = Reservefunctionroom.find(params[:id])
    @reservation = Reservation.find(params[:reservation_id])
    @reservefunctionroom = @reservation.reservefunctionrooms.build


  end

  # GET /reservefunctionrooms/1/edit
  def edit
    @reservefunctionroom = Reservefunctionroom.find(params[:id])
  end

  # POST /reservefunctionrooms
  # POST /reservefunctionrooms.json
  def create
    @reservation = Reservation.find(params[:reservation_id])
    @reservefunctionroom = @reservation.reservefunctionrooms.build(params[:reservefunctionroom])

    respond_to do |format|
      if @reservefunctionroom.save
        format.html { redirect_to @reservation, notice: 'Reservefunctionroom was successfully created.' }
        #format.json { render json: @reservefunctionroom, status: :created, location: @reservefunctionroom }
      else
        format.html { render action: "new" }
        #format.json { render json: @reservefunctionroom.errors, status: :unprocessable_entity }
      end
    end
  end

  # PUT /reservefunctionrooms/1
  # PUT /reservefunctionrooms/1.json
  def update
    @reservefunctionroom = Reservefunctionroom.find(params[:id])

    respond_to do |format|
      if @reservefunctionroom.update_attributes(params[:reservefunctionroom])
        format.html { redirect_to @reservefunctionroom, notice: 'Reservefunctionroom was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: "edit" }
        format.json { render json: @reservefunctionroom.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /reservefunctionrooms/1
  # DELETE /reservefunctionrooms/1.json
  def destroy
    @reservefunctionroom = Reservefunctionroom.find(params[:id])
    @reservefunctionroom.destroy

    respond_to do |format|
      format.html { redirect_to reservefunctionrooms_url }
      format.json { head :no_content }
    end
  end
end

我的模型reservefunctionroom.rb

  belongs_to :functionroom
  belongs_to :reservation

我的functionroom.rb

  has_many :reservefunctionrooms

我的视图resevefunctionroom/new.html.erb

<h1>New reservefunctionroom</h1>

<%= render 'form', :reservation => @reservation,
    :reservefunctionroom => @reservefunctionroom%>

<%= link_to 'Back', reservefunctionrooms_path %>

_form.html.rb

<%= form_for([reservation,reservefunctionroom]) do |f| %>
  <% if @reservefunctionroom.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@reservefunctionroom.errors.count, "error") %> prohibited this reservefunctionroom from being saved:</h2>

      <ul>
      <% @reservefunctionroom.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

这个应用程序做的并不多，但它只是创建了一个预订条目，错误点在new，如果需要任何其他东西，只要问我就可以了，感谢我们所有的力量

您需要在reservation模型中添加has_many :reservefunctionrooms。
