如何缩短Django中的分页

Question

我有一个包含600个房源的Django项目。我得到一个非常长的分页，我想知道如何缩短分页。也许不显示所有页码并替换一些...我正在使用bootstrap v4和django 1.10。我知道有些模块我可以使用，但我想学习。

模板

   {% if product.has_other_pages %}
                <div class="col-md-12 text-center">
                    <nav aria-label="">
                        <ul class="pagination">
                            {% if product.has_previous %}
                                <li class="page-item"><a class="page-link"
                                                         href="?page={{ product.previous_page_number }}">&laquo;</a>
                                </li>
                            {% else %}
                                <li class="page-item disabled"><a class="page-link"><span>&laquo;</span></a></li>
                            {% endif %}
                            {% for i in product.paginator.page_range %}
                                {% if product.number == i %}
                                    <li class="page-item active"><a class="page-link" href="#">{{ i }} <span
                                            class="sr-only">(current)</span></a></li>
                                {% else %}
                                    <li class="page-item"><a class="page-link" href="?page={{ i }}">{{ i }}</a></li>
                                {% endif %}
                            {% endfor %}
                            {% if product.has_next %}
                                <li class="page-item"><a class="page-link" aria-label="Next"
                                                         href="?page={{ product.next_page_number }}">&raquo;</a></li>
                            {% else %}
                                <li class="page-item disabled"><a class="page-link"><span>&raquo;</span></a></li>
                            {% endif %}
                        </ul>
                    </nav>
                </div>
            {% endif %}

视图

def products_all(request):
    products = Product.objects.order_by("-date_added")
    product_count = Category.objects.annotate(num_products=Count('product')).order_by('-num_products')[:5]
    company_count = Company.objects.annotate(num_products=Count('product')).order_by('-num_products')[:5]
    manufacturer_count = Manufacturer.objects.annotate(num_products=Count('product')).order_by('-num_products')[:5]

    total_manufacturer = Manufacturer.objects.count()
    total_company = Company.objects.count()
    total_categories = Category.objects.count()

    paginator = Paginator(products, 50)
    page = request.GET.get('page')

    try:
        product = paginator.page(page)
    except PageNotAnInteger:
        product = paginator.page(1)
    except EmptyPage:
        product = paginator.page(paginator.num_pages)

    template = "products/all.html"
    context = {'product': product,
               'products': products,
               'product_count': product_count,
               'company_count': company_count,
               'manufacturer_count': manufacturer_count,
               'total_categories': total_categories,
               'total_company': total_company,
               'total_manufacturer': total_manufacturer
               }


    return render(request, template, context)
