如何將新記錄表格移動到相關記錄顯示頁面？

Question

我有兩張桌子：場地和評論，其中1個場地可以有很多評論，評論屬於場地。我現在在會場展示頁面的鏈接添加評論到場館的評論新的一頁：

場地/ show.html.erb

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

評論/ new.html.erb

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

    <%= submit_tag %> 
<% end %> 

評論控制器

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 

個

場館控制器

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 

路線

resources :venues do 
    resources :reviews 
    end 
end 

我如何可以移動增加新的形式審查直接進入場館展示頁面？移動代碼給NilClass：Class錯誤提供了未定義的方法`model_name'。

感謝您的幫助！

Answer 1

只需將@review = Review.new添加到場館管制員的表演動作即可。然後把表格放在你的場地＃show view file中。

venues_controller.rb

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