</html>django-pure-pagination 分页
（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 %}
