如何将新记录表单移动到相关记录显示页面？

Question

我有2张桌子：场地和评论，其中1个场地可以有很多评论，评论属于一个场地。我目前通过场地展示页面中的链接添加评论到评论新页面：

地点/ show.html.erb

<div class="button">
  <%= link_to 'Add a review', new_venue_review_path(@venue) %>
</div>

的评价/ new.html.erb

<% form_for [@venue, @review] do |f| %>
  <p>title: <br>
  <%= f.text_field :title %></p>

  <%= submit_tag %>
<% end %>

评论控制器

  def new
    @review = Review.new
  end

  def create
    @review = Review.new params[:review]
    @review.venue = @venue
    if @review.save
      flash[:notice] = 'Review added'
      redirect_to venue_path(@venue)
    else
      render :action => :new
    end
  end

场地管制员

class VenuesController < ApplicationController

  def index
    if
      @venues = Venue.with_type(params[:venuetypes]).with_area(params[:areas])
    else
      @venues = Venue.all
    end
  end

  def new
    @venue = Venue.new
  end

  def create
    @venue = Venue.new params[:venue]
    if @venue.save
      flash[:notice] = 'Venue added'
      redirect_to venues_path
    else
      render :action => :new
    end
  end

  def edit
    @venue = Venue.find(params[:id])
  end

  def update
   @venue = Venue.find(params[:id])
   @venue.attributes = params[:venue]
   if @venue.save!
     flash[:notice] = 'Venue updated successfully'
     redirect_to venues_path(@venue)
   end
 end

 def show
   @venue = Venue.find(params[:id])
 end
end

路由

  resources :venues do
    resources :reviews
  end
end

如何将添加新评论表单直接移至场地展示页面？移动代码为NilClass提供了一个未定义的方法`model_name'：Class error。

感谢您的帮助！

Answer 1

只需将@review = Review.new添加到场地控制器的show动作中即可。然后将表格放在场地#show view file中。

<强> venues_controller.rb

def show
  @venue = Venue.find(params[:id])
  @review = Review.new
end
