如何檢索數組元素的值（字符串）並使用它來檢索實體的屬性值？

Question

如何檢索數組元素的值（字符串）並檢索實體的屬性值？我嘗試這樣做：

{% for item in items %} //item is an entity 
    {% for column in columns %} //column is just an array with name of columns 
    {% set columna = column.value %} 
    {{ item.columna }} 
    {% endfor %} 
{% endfor %} 

Answer 1

如果要動態地訪問一個對象的屬性，你可以使用attribute function：

{% for item in items %} 
    {% for column in columns %} 
    {{ attribute(item , column.value) }} 
    {% endfor %} 
{% endfor %} 

Answer 2

試試這個：

{% for item in items %} //item is an entity 
    {% for column in columns %} //column is just an array with name of columns 
    {% set columna = column.value %} 
    {{ attribute(item, columna) }} 
    {% endfor %} 
{% endfor %} 

我建議你閱讀documentation。
