- 自定义分页一：
views:
# -*- coding: utf-8 -*- from __future__ import unicode_literals from django.shortcuts import render,render_to_response from app01 import models
# Create your views here. def index(request, page):#用于获取前台get传来的数据 #操作数据库进行分页 page = int(page)#此时需要进行整数运算，所以需要强制类型转换 #per_item = 5 #第一页0-5，(page-1)*5 page*5 start = (page-1)*5 end = page*5 count = models.host.objects.all()[start:end].count()#此时就是实现了一部分一部分的获取数据 data = models.host.objects.all()[start:end] ret = {'data':data,'count':count} return render_to_response('index.html',ret)
index:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
</head>
<body>
<h1>主机信息</h1>
<table border="1" >
{% for item in data %}
<tr >
<td>{{ item.hostname }}</td>
<td>{{ item.ip}}</td>
<br />
</tr>
{% endfor %}
</table>
<div>总条数：{{ count }}</div>
</body>
</html>
urls:
from django.conf.urls import url,include
from django.contrib import admin
from app01 import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^index/(d+)', views.index),#id用于获取用户输入的页数
]
models:
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.db import models
# Create your models here.
class host(models.Model):
hostname = models.CharField(max_length=256)
ip = models.GenericIPAddressField()
此时的页面：
- 自定义分页二（进化版）：
views：
# -*- coding: utf-8 -*- from __future__ import unicode_literals from django.shortcuts import render,render_to_response from app01 import models from django.utils.safestring import mark_safe # Create your views here. def index(request, page): #判断获取的 值是否为整数 try: page = int(page) except Exception,e: page = 1 per_item = 5 start = (page-1)*5 end = page*5 count = models.host.objects.all().count() data = models.host.objects.all()[start:end] #判断需要分几页，divmod()是一个求商和余的函数 temp = divmod(count,per_item) if temp[1] == 0: all_page_count = temp[0] else: all_page_count = temp[0]+1 page_html=[] first_html = "<a href='/index/%d'>首页</a>"%(1,) page_html.append(first_html) for i in range(all_page_count): a_html = "<a href='/index/%d'>%d</a>"%(i+1,i+1) page_html.append(a_html) end_html = "<a href='/index/%d'>尾页</a>" % (all_page_count,) page_html.append(end_html) page = mark_safe(''.join(page_html))#想要在页面上显示关键字就必须要确认他不是类似跨站脚本的东西 ret = {'data':data,'count':count,'page':page} return render_to_response('index.html',ret)
html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
</head>
<body>
<h1>主机信息</h1>
<table border="1" >
{% for item in data %}
<tr >
<td>{{ item.hostname }}</td>
<td>{{ item.ip}}</td>
<br />
</tr>
{% endfor %}
</table>
<div>总条数：{{ count }}</div>
{{ page }}
</body>
</html>
其余一样
显示页面：
- 自定义分页（第三种）：
views：

from app01 import models
from django.utils.safestring import mark_safe

try:
page = int(page)
except Exception,e:
page = 1
per_item = 5
start = (page-1)*5
end = page*5
count = models.host.objects.all().count()
data = models.host.objects.all()[start:end]
#判断需要分几页，divmod()是一个求商和余的函数
temp = divmod(count,per_item)
if temp[1] == 0:
all_page_count = temp[0]
else:
all_page_count = temp[0]+1
page_html=[]
first_html = "<a href='/index/%d'>首页</a>" % (1,)
page_html.append(first_html)
if page == 1:
prv_html = "<a href='/index/#'>上一页</a>"
else:
prv_html = "<a href='/index/%d'>上一页</a>"%(page-1,)
page_html.append(prv_html)
for i in range(all_page_count):
if page == i+1:
a_html = "<a style='color:red;' href='/index/%d'>%d</a>"%(i+1,i+1)
else:
a_html = "<a href='/index/%d'>%d</a>"%(i+1,i+1)
page_html.append(a_html)
next_html = "<a href='/index/%d'>下一页</a>" % (page+1,)
page_html.append(next_html)
end_html = "<a href='/index/%d'>尾页</a>" % (all_page_count,)
page_html.append(end_html)
page = mark_safe(''.join(page_html))#想要在页面上显示关键字就必须要确认他不是类似跨站脚本的东西
ret = {'data':data,'count':count,'page':page}
return render_to_response('index.html',ret)

#当所分的页数特别多时，需要微量显示
if all_page_count < 11:
begin = 0

end = 12
else:
