django自定义分页分页类
django中封装了自定义分页的功能，但是自己怎么用，怎么感觉不爽，于是是自己就查阅资料，再耗时了几天后，终于整理出了
自己的分页类，在这里分享给大家，当然代码中带有不足，大家多多见谅。。 声明在py2 要是在py3中死都不知道怎么死的....
最后的效果
1.首先建立 PageClass.py
#coding:utf-8 from django.utils.safestring import mark_safe class PageInfo(object): # current_page 当前页 # all_count 总条数 # per_item 每页的条数 # page_count显示的页码数 def __init__(self,current_page,all_count,per_item=5,page_count=5): try: current_page = int(current_page) except Exception as e: current_page = 1 self.CurrentPage=current_page self.AllCount=all_count self.PerItem=per_item self.PageCount = page_count @property def start(self): return (self.CurrentPage-1)*self.PerItem @property def end(self): return self.CurrentPage*self.PerItem @property def all_page_count(self): temp = divmod(self.AllCount, self.PerItem) if temp[1]==0: all_page_num = temp[0] else: all_page_num = temp[0]+1 return all_page_num def page_str(self,base_url): # base_url页面访问的路径 page_html = [] first = "<a class='action' href='%s%d'>首页</a>" % (base_url,1) page_html.append(first) if self.CurrentPage <= 1: prev = "<a class='action' href='javascript:void(0);'>上一页</a>" else: prev = "<a class='action' href='%s%d'>上一页</a>" % (base_url,self.CurrentPage - 1) page_html.append(prev) if self.all_page_count <self.PageCount+1: begin = 0 end = self.all_page_count # 总页数大于设置的页数 else: if self.CurrentPage < (self.PageCount+1)/2: begin =0 end = self.PageCount else: if self.CurrentPage+5 > self.all_page_count: begin = self.CurrentPage-(self.PageCount+1)/2 end = self.all_page_count else: begin = self.CurrentPage - (self.PageCount+1)/2 end = self.CurrentPage + (self.PageCount-1)/2 for i in range(begin,end): if self.CurrentPage == (i + 1): a_html = "<a class='action page' href='%s%d'>%d</a>" % (base_url,i + 1, i + 1) else: a_html = "<a class='action' href='%s%d'>%d</a>" % (base_url,i + 1, i + 1) page_html.append(a_html) if self.CurrentPage == self.all_page_count: next = "<a class='action' href='javascript:void(0);'>下一页</a>" else: next = "<a class='action' href='%s%d'>下一页</a>" % (base_url,self.CurrentPage + 1,) page_html.append(next) last = "<a class='action' href='%s%d'>尾页</a>" % (base_url,self.all_page_count,) page_html.append(last) page_string = mark_safe("".join(page_html)) return page_string
在views.py中
from app01 import PageClass def pages(request,pid): count = models.Host.objects.all().count() page = PageClass.PageInfo(pid,count) data = models.Host.objects.all()[page.start:page.end] page_str = page.page_str('/zuhe/pages/') ret = {'data':data,'count':count,'page':page_str} return render(request,'zuhe/pages.html',ret)
模型中只是一堆的数据就不显示了
在html页面中
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <style> .action{ background: #084;text-decoration: none;display: inline-block;border: 1px solid #078; color: #fff;padding: 5px;margin: 3px;} .page{color: red;background:#080;} </style> </head> <body> <ul> {% for v in data %} <li>{{ v.id }}--{{ v.HostName }} -- {{ v.HostIp }}</li> {% endfor %} <h4>总数：{{ count }}</h4> {{ page }} </ul> </body> </html>
在html中只是需要对样式的修改即可
