• 導(dǎo)入django內(nèi)置的分頁(yè)器
  from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
• 定義一個(gè)分頁(yè)器函數(shù)

def make_paginator(objects, page, num=1):
    paginator = Paginator(objects, num)
    try:
        object_list = paginator.page(page)
    except PageNotAnInteger:
        object_list = paginator.page(1)
    except EmptyPage:
        object_list = paginator.page(paginator.num_pages)
    return object_list, paginator

• 在index中將文章總數(shù)和當(dāng)前訪問(wèn)頁(yè)碼傳入分頁(yè)器函數(shù)

def index(request):
    entries = models.Entry.objects.all()
    page = request.GET.get('page', 1)
    entry_list, paginator = make_paginator(entries, page)
    page_data = pagination_data(paginator, page)
    return render(request, 'blog/index.html', locals())

• 在index模板中寫入代碼

                {%  if entry_list.has_previous %}
                    <li><a href="?page={{ entry_list.previous_page_number }}"><i class="glyphicon glyphicon-chevron-left"></i>前一頁(yè)</a></li>
                {% endif %}

                {% if first %}
                    <li><a href="?page=1">1</a></li>
                {% endif %}

                {% if left %}
                    {% if left_has_more %}
                        <span>...</span>
                    {% endif %}

                    {% for i in left %}
                        <li><a href="?page={{ i }}">{{ i }}</a></li>
                    {% endfor %}
                {% endif %}


                <li class="active"><a href="?page={{ entry_list.number }}">{{ entry_list.number }}</a></li>

                {% if right %}
                    {% for i in right %}
                        <li><a href="?page={{ i }}">{{ i }}</a></li>
                    {% endfor %}

                    {% if right_has_more %}
                        <span>...</span>
                    {% endif %}
                {% endif %}

                {% if last %}
                    <li><a href="?page={{ entry_list.num_pages }}">{{ entry_list.num_pages }}</a></li>
                {% endif %}

                {% if entry_list.has_next %}
                    <li><a href="?page={{ entry_list.next_page_number }}">下一頁(yè)<i class="glyphicon glyphicon-chevron-right"></i></a></li>
                {% endif %}
                </ul>
