您需要一个包含events 和posts 的上下文的视图

class EventView(View):
    def get(self, request):
        events = Event.objects.all()
        posts = Blog.objects.all()
        return render(request, "home/home_list.html", {"events": events, "posts":posts})

模板

在两者的模板循环中

{% if posts %}
{% for p in posts %}
    {{ p.title }}
{% endfor %}
{% else %}
<p>У вас нет материала</p>
{% endif %}
{% if events %}
{% for e in events %}
        {{ e.name }}
    {% endfor %}
{% else %}
    <p>У вас нет материала</p>
{% endif %}

谢谢，您的回答有帮助。

【解决方案2】：

在每个循环中，为“循环对象”和要循环的列表/字典使用不同的名称。像这样：

{% if post %}
    {% for p in post %}
        {{ p.title }}
    {% endfor %}
{% else %}
    <p>У вас нет материала</p>
{% endif %}
{% if event %}
    {% for e in event %}
        {{ e.name }}
    {% endfor %}
{% else %}
    <p>У вас нет материала</p>
{% endif %}

它解决了你的问题吗？
