您应该创建一个filter标记,它将接收您的queryset并返回一个filtered标记。。。。您可以在此处找到详细信息:

https://docs.djangoproject.com/en/2.1/howto/custom-template-tags/

您可以检查您的视图中按下了哪个输入,并根据它,重定向到列表或新的空白表单。

使用 HttpResponse

from django.http import HttpResponse
def yourView(request):    
    return HttpResponse('401 Unauthorized', status=401)

在这里找到了解决方案: How do I return a 401 Unauthorized in Django?

你快到了。试试这个:

views.py

from news.models import News
from django.shortcuts import render

def HomePageView(request):
    context = {}
    news = News.objects.order_by('-date')[:3]  
    context['news']=news 
    return render(request,'home.html',context)

home.html

    {% extends 'base.html' %}

    {% block title %}Home{% endblock title %}

    {% block content %}
        <div class="jumbotron">
            <h1 class="display-4">Lakeland Cycle Club</h1>
            <p class="lead">The home of cycling in Fermanagh.</p>
            <p class="lead">
                <a class="btn btn-primary btn-lg" href="{% url 'news_list' %}" role="button">View All Club News</a>
            </p>
             <span class="font-weight-bold">
               {%for new in news%}
{{new.title}}
{%endfor%}
            </span>
        </div>
    {% endblock content %}
