django分页的两种方式

第一种自定义分页：

def pageDemo(request):
    ‘‘‘
    自定义分页]
    :param request:
    :return:
    ‘‘‘
    currentpage=request.GET.get(‘pageIndex‘)
    pageSize=2
    if not currentpage or int(currentpage)<1:
        currentpage=1
    current_page=int(currentpage)
    start=(current_page-1)*pageSize
    end=current_page*pageSize
    data=userInfo.objects.all()[start:end]
    if current_page*pageSize>userInfo.objects.all().count():
        nextpage=current_page
    else:
        nextpage=current_page+1
    if current_page<=1:
        previous_page=1
    else:
        previous_page=current_page-1
    data={
            ‘data‘:data,
             ‘nextPage‘:nextpage,
             ‘prevpage‘: previous_page
        }
    return render(request, ‘app02/Paginator.html‘, data)
html:

<div>
    <a href="/app02/pagination1/?pageIndex={{nextPage}}">下一页</a>
     <a href="/app02/pagination1/?pageIndex={{prevpage}}">上一页</a>
</div>

第二种分页：使用分页器

def pageDemoWithpaginator(request):

    ‘‘‘
    使用django的分页器分页
    :param request:
    :return:
    ‘‘‘
    #查询数据
    userdata=userInfo.objects.all()
    #第二步：生成分页实例
    pageinstance=Paginator(userdata,2)
    #获取当前页面页码
    currentPage=request.GET.get(‘pageIndex‘,1)
    #获取指定页码的数据
    pagedata=pageinstance.page(currentPage)
    #将数据返回到页面
    return render(request, ‘app02/Paginator.html‘, {‘data‘:pagedata})

html：

<div id="pagination">
    <ul id="pagination-flickr">
        {% if data.has_previous %}
            <li ><a href="/app02/pagination/?pageIndex={{ data.previous_page_number }}">&laquo;上一页</a></li>
        {% else %}
            <li >&laquo;上一页</li>
        {% endif %}
        <li >{{ data.number }}/{{ data.paginator.num_pages }}</li>
        {% if data.has_next %}
            <li ><a href="/app02/pagination/?pageIndex={{ data.next_page_number }}">下一页 &raquo;</a></li>
        {% else %}
            <li>下一页 &raquo;</li>
        {% endif %}
    </ul>
</div>
