怪我咯 · Answer

I don’t know if I understand your question.

According to my understanding, you need:

# view
# 取出多个随机元素
# 元素个数不足什么的请自己注意处理
kwargs["paragraphs"] = Content.objects.order_by("?")[:3].content

{# 模版 #}
{# 在循环过程中分别渲染各个“随机段落” #}
{% for paragraph in paragraphs %}
    {{ paragraph }}
{% endfor %}
