Django分页功能的实现

views 代码：

from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger

columns = Column.objects.all()
articles = Article.objects.all()


def index(request):
    cus_list = Article.objects.all()
    paginator = Paginator(cus_list, 1)

    page = request.GET.get('page')
    if page:
        article_list = paginator.page(page).object_list
    else:
        article_list = paginator.page(1).object_list
    try:
        customer = paginator.page(page)
    except PageNotAnInteger:
        customer = paginator.page(1)
    except EmptyPage:
        customer = paginator.page(paginator.num_pages)

    return render(request, 'index.html', {'cus_list': customer, 'columns': columns, 'articles': article_list})

中间if语法是显示数据的，paginator.page(page).object_list  表示的是page这一页里面的数据集

try语法是分页功能的实现

html模板：

<nav aria-label="Page navigation">
    <ul class="pagination">
        {% if cus_list.has_previous %}
            <li>
            <a href="?page={{ cus_list.previous_page_number }}" aria-label="Previous"><span aria-hidden="true">«</span></a>
            </li>
        {% endif %}

       {% for pg in cus_list.paginator.page_range %}
        {% if cus_list.number == pg %}
        <li class="active"><a href="?page={{ pg }}">{{ pg }}</a></li>
        {% else %}
        <li><a href="?page={{ pg }}">{{ pg }}</a></li>
        {% endif %}
        {% endfor %}
        {% if cus_list.has_next %}
        <li><a href="?page={{ cus_list.next_page_number }}" aria-label="Next"><span aria-hidden="true">»</span></a></li>
        {% endif %}
    </ul>
</nav>

app下面的urls：

url(r'^$', views.index, name='index'),
