{% with lang={{request.LANGUAGE_CODE}} %} 
 
{% endwith %} 
 

 
      <p> 
 
       {% if lang == 'zh-CN' %} {{object.category.name_zh_CN}} {% else %} {{object.category.name}} {% endif %}

Answer 1

並不需要{% %}內的雙大括號，而不是你可以簡單地使用變量：

{% with lang=request.LANGUAGE_CODE %} 
{% endwith %} 
<p> 
    {% if lang == 'zh-CN' %} {{object.category.name_zh_CN}} {% else %} {{object.category.name}} {% endif %} 
</p> 

您可以在django template guide閱讀更多關於這一點。

Answer 2

{% with lang=request.LANGUAGE_CODE %} 
    <p> 
     {% if lang == 'zh-CN' %} {{object.category.name_zh_CN}} {% else %} {{object.category.name}} {% endif %} 
    </p> 
{% endwith %} 

但可以將其簡化：

<p> 
    {% if request.LANGUAGE_CODE == 'zh-CN' %} {{object.category.name_zh_CN}} {% else %} {{object.category.name}} {% endif %} 
</p>
