为什么不能显示餐厅列表?

问题描述

我正在尝试制作一些餐厅列表.我关联了两个表，然后写了这段代码.

I'm trying to make some restaurant list.I associated two tables, and then write this code.

class Restaurant < ActiveRecord::Base
        has_many :restaurant_translations
end

class RestaurantTranslation < ActiveRecord::Base
        self.table_name = 'restaurant_translations'
end

restaurant_controller.rb

restaurant_controller.rb

class RestaurantController < ApplicationController
        def list
                @restaurants = Restaurant.all
logger.debug @restaurants
        end
end

list.html.slim桌子头tr类型姓名网址流派第一个地址

list.html.slim table thead tr th Type th Name th Url th Genre th Addr

  tbody
    - @restaurants.each do |restaurant|
      tr
        td = restaurant.restaurant_type
        td = restaurant.restaurant_translations.restaurantname
        td = link_to 'here', restaurant.url
        td = restaurant.genre
        td = restaurant.restaurant_translations.address

但结果如下.未定义方法`restaurantname' #"

But results are belows."undefined method `restaurantname' for #"

我该如何解决这个问题?提前致谢.

How can I do this problem? Thanks in advance.

推荐答案

您的餐厅有多个restaurant_translations".

Your restauration have multiple 'restaurant_translations'.

例如，首先你可以写td = restaurant.restaurant_translations.first.try(:restaurantname)
