python - Django - 是否可以根据模型字段内的内容添加模板渲染条件？

Question

我想使用检测字符串匹配的条件在模板内呈现内容。如果前几个字符串通过条件，那么我想渲染所述对象字段，如果没有，则跳过该对象。

有问题的字段是用于存储博客文本的大型内容字段。此字段具有 HTML 标记，例如<p>或<iframe>。我希望这个模板渲染检测<iframe>字符串，作为条件。

这是我的代码：

查看.py：

def homepage(request, *args, **kwargs):
    obj = blog.objects.filter(posted=True).order_by('-date_posted')

    posts = {
        'object': obj
    }

    return render(request=request, template_name="home.html", context=posts)

html：

<div class="container px-5 py-10 mx-auto md:px-20 lg:px-30">
          {% for post in object|slice:":4" %}
          <div class="p-12 md:w-1/2 flex flex-col items-start">
            <span
              class="
                inline-block

              >{{ post.subtitle }}</span
            >
            <span class="mt-1 text-gray-500 text-sm font-mono"

{% for post in object|slice:":4" %}如何自定义此渲染或添加其他可以作为检测条件传递的标签<iframe>？
