廚師數據包中有數組嗎？

我想將散列數據包含在廚師數據庫項目中。這是否支持？我不斷收到有關未定義方法的錯誤消息。這裏有一個例子：廚師數據包中有數組嗎？

Databag項目：

{ 
     "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 -%>

如果我只能訪問三明治和暱稱領域，我很好，但只要我添加代碼迭代通過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 -%>

謝謝！

並感謝CodeRanger !!!

添加下面的內容，這裏固定它，因爲我顯然還沒有格式化評論的訣竅呢。

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

訪問哈希在Ruby中的方法是通過[]語法，所以@restaurant['value_meals'].each和meal['side']。

謝謝！修改爲：<！ - 但也有價值餐...... - > <％@restaurant ['value_meals']。餐| ％> <% end -%> <％= meal ['sandwich']％>，<％= meal ['side']％>％>>％> 它像一個冠軍一樣工作！對糟糕的格式化抱歉......對於新的格式。 –
