?Django內(nèi)置了分頁(yè)設(shè)置，但不夠靈活，需要我們自定義分頁(yè)。

下面代碼考慮了利用bootstrap分頁(yè)組件來(lái)實(shí)現(xiàn)頁(yè)面美化，如果不想使用，可以不調(diào)用url_format_by_bootstrap函數(shù)，即可實(shí)現(xiàn)普通分頁(yè)。

具體的參數(shù)和代碼均有注釋

在view頁(yè)面只需要傳參數(shù)就可生成頁(yè)碼

            
              import logging

from django.http import HttpResponse
from django.shortcuts import render
from . import models
from utils.pager import PageInfo


def index(request):
    """首頁(yè)"""
    try:
        current_page_num = int(request.GET['page'])
    except Exception as e:
        logging.log(logging.ERROR, e)
        current_page_num = 1
    data = models.UserInfo.objects.all()
    page_info = PageInfo(current_page_num, data, '/index')
    page_list = page_info.create_page()
    user_list = page_info.per_page_content(data)
    return render(request, 'index.html', {'user_list': user_list, 'page_list': page_list})

由于是后端動(dòng)態(tài)生成頁(yè)碼標(biāo)簽，前段直接遍歷即可。

這里應(yīng)用了bootstrap樣式。

            
              
              
              
              

                用戶(hù)列表
              
              

                
            {% for row in user_list %}
                
                

                  {{ row.username }}
                
                
            {% endfor %}
        
              
              
            
          

具體效果如下：
