请先看在学习tornado时，写的自定义分页类：思路一致；
1.基础使用：
后台数据获取：
from django.core.paginator import Paginator,PageNotAnInteger,EmptyPage#错误判断
List_info = [] for i in range(1000): List_info.append("news%d"%i) def get_page(req): current_page = req.GET.get('p') paginator = Paginator(List_info,10) #传入总数据和每页显示的数据
#含有属性：
#per_page:每页显示条数上面的10
#count数据总数
#num_pages:总页数
#page_range:总页数索引范围
#page：page对象 try: posts = paginator.page(current_page)
#page对象含有方法：
#has_next：判断是否有下一页
#has_previous:判断是否有上一页
#next_page_number：下一页页码
#previous_page_number：上一页页码
#number：当前页 注意：这个是属性，其他是方法，需要加上()
#paginator:paginator对象 except PageNotAnInteger: posts = paginator.page(1) except EmptyPage: posts = paginator.page(paginator.num_pages) #num_pages数总页数，最后一页 return render(req,'get_page.html',{'posts':posts})
前端代码：
<div class="content"> {% for item in posts %} <p>{{ item }}</p> {% endfor %} </div> <div> <span> {% if posts.has_previous %} #模板中调用函数不要() <a href="/page.html?p={{ posts.previous_page_number }}">prev</a> {% endif %} <span class="current"> Page {{ posts.number }} of {{ posts.paginator.num_pages }} </span> {% if posts.has_next %} <a href="/page.html?p={{ posts.next_page_number }}">next</a> {% endif %} </span> </div>
2.扩展内置分页：
类修改：
from django.core.paginator import Paginator class CustomPagimator(Paginator): def __init__(self,current_page,max_page_num,*args,**kwargs): self.current_page = int(current_page) #当前页 #自定义变量 self.max_page_num = max_page_num #可以显示多少页 #自定义变量 super(CustomPagimator,self).__init__(*args,**kwargs) def page_num_range(self): # self.num_pages 总页数 part_num = int(self.max_page_num/2) if self.num_pages <= self.max_page_num: #先判断总页数和运行显示的页数大小 return range(1, self.num_pages + 1) if self.current_page <= part_num: #再取半分析 return range(1,self.max_page_num+1) elif self.current_page+part_num>= self.num_pages: return range(self.num_pages-self.max_page_num,self.num_pages+1) else: return range(self.current_page - part_num, self.current_page + part_num + 1)
类调用：
List_info = [] for i in range(1000): List_info.append("news%d"%i)
from 模块.自定义分页类文件 import 自定义分页类CustomPagimator
def get_page(req): current_page = req.GET.get('p') paginator = CustomPagimator(current_page=current_page, max_page_num=5,object_list=List_info,per_page=10) #传入总数据和每页显示的数据 try: posts = paginator.page(current_page) except PageNotAnInteger: posts = paginator.page(1) except EmptyPage: posts = paginator.page(paginator.num_pages) #num_pages数总页数，最后一页 page_html = paginator.page_num_range() return render(req,'get_page.html',{'posts':posts,"page_html":page_html})
前端使用：
<div>
<span>
{% if posts.has_previous %}
<a href="/page.html?p={{ posts.previous_page_number }}">prev</a>
{% endif %}
<span class="page">
{% for i in page_html %}
<a href="/page.html?p={{ i }}">{{ i }}</a>
{% endfor %}
</span>
<span class="current">
Page {{ posts.number }} of {{ posts.paginator.num_pages }}
</span>
{% if posts.has_next %}
<a href="/page.html?p={{ posts.next_page_number }}">next</a>
{% endif %}
</span>
</div>
