无法解析“{request.LANGUAGE_CODE}”中的“{request.LANGUAGE_CODE}”余数

Question

我用django 1.11编程，现在我有了下面的post_list.html脚本

​

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

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

Answer 1

在{% %}中不需要使用双花括号，而只需使用以下变量：

{% 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模板指南中阅读更多有关这方面的内容。

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>
