{% if stus.has_previous %}
    <a href="/students/{{ stus.previous_page_number }}">上一页</a>
{% endif %}


{% for index in stus.paginator.page_range %}
    {% if index == stus.number %}
        {{ index }}
    {% else %}

django-pure-pagination 分页

地址

（1）安装

pip install django-pure-pagination

（2）settings里面添加

INSTALLED_APPS = (
    ...
    'pure_pagination',
)

（3）views中使用方法

class OrgView(View):
    '''课程机构'''

    def get(self, request):
        # 所有课程机构
        all_orgs = CourseOrg.objects.all()
        # 有多少家机构
        org_nums = all_orgs.count()
        # 所有城市
        all_citys = CityDict.objects.all()
        # 对课程机构进行分页
        # 尝试获取前台get请求传递过来的page参数
        # 如果是不合法的配置参数默认返回第一页
        try:
            page = request.GET.get('page', 1)
        except PageNotAnInteger:
            page = 1
        # 这里指从allorg中取五个出来，每页显示5个
        p = Paginator(all_orgs, 5, request=request)
        orgs = p.page(page)

        return render(request, "org-list.html", {
            "all_orgs": orgs,
            "all_citys": all_citys,
            "org_nums": org_nums,
        })

（4）模板修改

#{%for course_org in all_orgs%}
{%for course_org in all_orgs.object_list%}
...
{%endfor%}

（5）分页功能

<div class="pageturn">
    <ul class="pagelist">
        {% if all_orgs.has_previous %}
            <li class="long"><a href="?{{ all_orgs.previous_page_number.querystring }}">上一页</a></li>
        {% endif %}

        {% for page in all_orgs.pages %}
            {% if page %}
                {% ifequal page all_orgs.number %}
                    <li class="active"><a href="?{{ page.querystring }}">{{ page }}</a></li>
                {% else %}
                    <li><a href="?{{ page.querystring }}" class="page">{{ page }}</a></li>
                {% endifequal %}
            {% else %}
                <li class="none"><a href="">...</a></li>
            {% endif %}
        {% endfor %}
        {% if all_orgs.has_next %}
            <li class="long"><a href="?{{ all_orgs.next_page_number.querystring }}">下一页</a></li>
        {% endif %}
    </ul>
</div>
