Django分页（一）

 

 

手动实现简单分页

 

HTML

    
          
      
    
       
                {
     % for user in user_list %}            
        
{
    { user.name }} {
    { user.age }} 
        {
     % endfor %}        {
     { prev_page }}
        上一页        {
     { next_page }}
        下一页    
       
      

 

 Views代码

from django.shortcuts import render,HttpResponse,redirectfrom blog.models import *from django.views import View# Create your views here.USER_LIST=[]for i in range(888):    temp={'name':'root'+str(i),'age':i}    USER_LIST.append(temp)    per_page_count = 10  # 定义每页要显示多少行数据def get_index(request):    current_page=request.GET.get('p')#获取客户端传过来的参数，得到翻到哪一页    current_page = int(current_page)  # 字符--〉数字    start = (current_page - 1) * per_page_count  # 定义从哪一行开始    end = current_page * per_page_count  # 定义数据在哪一行结束    data = USER_LIST[start:end]  # 对数据进行切片    # p=1    # 0,10  0-9    # p=2    # 10,20 10-19    #上一页    prev_page=current_page-1#下一页    next_page=current_page+1    return render(request,"index.html",{'user_list':data,'prev_page':prev_page,'next_page':next_page})

　　

 

 

 

Django分页简单使用

 

在html文件下创建include目录，然后把分页功能代码放入其中

使用include引入功能html文件

功能html文件如下：

{% if posts.has_previous %}            Previous        {% endif %}		            Page {
    { posts.number }} of {
    { posts.paginator.num_pages }}.				{% if posts.has_next %}		Next		{% endif %}

　　

 

HTML

    
          
      
    
       
        
        
                     {
     % for user in posts.object_list %}            
         
{
    { user.name }} {
    { user.age }} 
            {
     % endfor %}        
        
        {
     % if posts.has_previous %}            
        Previous        {
     % endif %}        
                    Page {
     { posts.number }} of {
     { posts.paginator.num_pages }}.                {
     % if posts.has_next %}        
        Next        {
     % endif %}

Django分页自定义使用

 

 功能html

{% if posts.has_previous %}    Previous{% endif %}    {% for i in posts.paginator.page_num_range %}        {
    { i }}    {% endfor %}    {% if posts.has_next %}        Next    {% endif %}

　　

HTML

    
         
     
    
      
		
       
        			{% for user in posts.object_list %}            
        
{
    { user.name }} {
    { user.age }} 
			{% endfor %}		
       
			{%  include 'include/page1.html'  %}
