ListView 分页重定向到主页

我根据 Listview 类进行分页。当我点击任何按钮 - “下一页”，“1 2 3”时，我会被重定向到主页“主页”。也许有人可以解释为什么会发生这种情况？我不是要求你为我编写代码，只是解释一下这里发生了什么。

视图.py

class AllPost(DataMixin, ListView):
template_name = 'main_package/all_post.html'
context_object_name = 'all_post'
title_page = 'ПЛАТФОРМА44.РУ - Все статьи'
paginate_by = 9

def get_queryset(self):
    return Post.published.all().select_related('cat')

那也不起作用。

class AllPost(DataMixin, ListView):
template_name = 'main_package/all_post.html'
context_object_name = 'all_post'
title_page = 'ПЛАТФОРМА44.РУ - Все статьи'
contact_list = Post.published.all()
paginator = Paginator(contact_list, 4)
paginate_by = 9

def get_queryset(self):
    return Post.published.all()

def get_context_data(self, **kwargs):
    context = super().get_context_data(**kwargs)
    context['page_obj'] = self.paginator.page(self.request.GET.get('page', 1))
    return context

它也无法通过该函数起作用。

contact_list = Post.published.all()
paginator = Paginator(contact_list, 3)
page_number = request.GET.get('page')
page_obj = paginator.get_page(page_number)
return render(request, 'main_package/all_post.html',
              {'title': 'Все статьи', 'page_obj': page_obj})

全部帖子.html

    <a href="?page={{ page_obj.next_page_number }}" class="button" title="Следующая страница"
       {% if not page_obj.has_next %} style="display:none;" {% endif %}>Следующая страница <i
            class="fa fa-angle-double-right"></i></a>
    <div class="pagination">
        {% if page_obj.has_previous %}
        <a href="?page={{ page_obj.previous_page_number }}" class="pagination-left" title="Предыдущая страница">&laquo;</a>
        {% endif %}
        {% for p in page_obj.paginator.page_range %}
        {% if page_obj.number == p %}
        <span class="active">{{ p }}</span>
        {% else %}
        <a href="?page={{ p }}" title="Перейти на страницу {{ p }}">{{ p }}</a>
        {% endif %}
        {% endfor %}
        {% if page_obj.has_next %}
        <a href="?page={{ page_obj.next_page_number }}" class="pagination-right"
           title="Следующая страница">&raquo;</a>
        {% endif %}
    </div>
</section>

而且它也不起作用。

{% if page_obj.has_other_pages %}
<nav class="list-pages">
<ul>
    {% if page_obj.has_previous %}
    <li class="page-num">
        <a href="?page={{ page_obj.previous_page_number }}">&lt;</a>
    </li>
    {% endif %}
    {% for p in paginator.page_range %}
    {% if page_obj.number == p %}
    <li class="page-num page-num-selected">{{ p }}</li>
    {% elif p >= page_obj.number|add:-2 and p <= page_obj.number|add:2 %}
    <li class="page-num">
        <a href="?page={{ p }}">{{ p }}</a>
    </li>
    {% endif %}
    {% endfor %}
    {% if page_obj.has_next %}
    <li class="page-num">
        <a href="?page={{ page_obj.next_page_number }}">&gt;</a>
    </li>
    {% endif %}
 </ul>
 </nav>
{% endif %}
