Question

我使用django 1.11进行编程，现在我在post_list.html中有以下脚本

＆＃13;

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

＆＃13;

但我实际上无法得到以下错误消息，请帮忙。谢谢。

Answer 1

{% %}中不需要双花括号，而只需使用变量：

{% 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。

中详细了解相关信息

Answer 2

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

但你可以简化它：

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

无法解析余数：＆＃39; {{request.LANGUAGE_CODE}}＆＃39;来自＆{39; {{request.LANGUAGE_CODE}}＆＃39;
