厨师数据包中有数组吗？

我想将散列数据包含在厨师数据库项目中。这是否支持？我不断收到有关未定义方法的错误消息。这里有一个例子：厨师数据包中有数组吗？

Databag项目：

{ 
     "id": "BurgerKing", 
     "sandwich": "Whopper", 
     "nickname": "BK", 
     "value_meals":[ 
       { 
       "sandwich": "Big King", 
       "side": "Fries", 
       "drink": "Coke" 
       }, 
       { 
       "sandwich": "Kids Burger", 
       "side": "Apple Slices", 
       "drink": "Milk" 
       } 
     ] 
}

模板：

<!-- I want to go to <%= @restaurant[ 'nickname' ] %> to get a <%= @restaurant['sandwich'] %>. --> 
<!-- But there are also value meals... --> 
<% @restaurant.value_meals.each do | meal | %> 
<!-- <%= meal.sandwich %>, <%= meal.side %>, and <%= meal.drink %> --> 
<% end -%>

如果我只能访问三明治和昵称领域，我很好，但只要我添加代码迭代通过value_meals，我得到：

Chef::Mixin::Template::TemplateError (undefined method `value_meals' for #<Chef::DataBagItem:0x00000002d07df0>) on line #6: 

    4: <!-- I want to go to <%= @restaurant[ 'nickname' ] %> to get a <%= @restaurant['sandwich'] %>. --> 
    5: <!-- But there are also value meals... --> 
    6: <% @restaurant.value_meals.each do | meal | %> 
    7: <!-- <%= meal.sandwich %>, <%= meal.side %>, and <%= meal.drink %> --> 
    8: <% end -%>

谢谢！

并感谢CodeRanger !!!

添加下面的内容，这里固定它，因为我显然还没有格式化评论的诀窍呢。

<!-- But there are also value meals... --> 
<% @restaurant['value_meals'].each do | meal | %> 
<!-- <%= meal[ 'sandwich' ] %>, <%= meal[ 'side' ] %>, and <%= meal[ 'drink' ] %> --> 
<% end -%>

访问哈希在Ruby中的方法是通过[]语法，所以@restaurant['value_meals'].each和meal['side']。

谢谢！修改为：<！ - 但也有价值餐...... - > <％@restaurant ['value_meals']。餐| ％> <% end -%> <％= meal ['sandwich']％>，<％= meal ['side']％>％>>％> 它像一个冠军一样工作！对糟糕的格式化抱歉......对于新的格式。 –
