Django模型和模板标记：使用模型字段值作为注入标记

Question

我有一个模板基本代码，如下所示。模板将注入模型 主题 中的内容。现在， topic.div_element 包含在 views.py views.py中使用外部（由地图生成）生成的div代码注入的标记的名称EM> 即可。目前，下面的代码工作正常。

{% block body_block %}
{% if topics %}
{% for topic in topics %}
<div class="content-block" id= {{ topic.section_num }}>
  <div class="row ">
    <div class="col " align="center">
      <h2>{% autoescape off %}{{ topic.section }}{% endautoescape %} </h2>
    </div>
  </div>
  <div class="row ">
    <div class="col-md-12 ">
      {% if topic.div_element == "div_plot_donut" %}
        <div class="embed-responsive embed-responsive-8by9">
          {{div_plot_donut|safe}}
        </div>
      {% elif topic.div_element == "div_line" %}
        <div class="embed-responsive embed-responsive-8by9">
          {{div_line|safe}}
        </div>
      {% elif topic.div_element == "div_bar" %}
        <div class="embed-responsive embed-responsive-8by9">
          {{div_bar|safe}}
        </div>
      {%else%}
        <p>Not found</p>
      {% endif %}
    </div>
  </div>
</div>
{% endfor %}
{% else %}
<p> Nothing found  </p>
{% endif %}

正如您所看到的，if else部分看起来很愚蠢，我将topic.div_element与单个字符串值进行比较，然后将该值基本上作为标记添加。

  {% if topic.div_element|stringformat:"s" == "div_plot_donut" %}
    <div class="embed-responsive embed-responsive-8by9">
      {{div_plot_donut|safe}}
    </div>
  {% elif topic.div_element == "div_line" %}
    <div class="embed-responsive embed-responsive-8by9">
      {{div_line|safe}}
    </div>

有没有办法做这样的事情，而不是有一个if-else结构：

<div class="col-md-12 ">
    <div class="embed-responsive embed-responsive-8by9">
      {{topic.div_element|safe}}
    </div>
</div>
