实际应用案例：

from django.urls import re_path
from app01 import views

# app01views.py
from django.views import View
from django.shortcuts import render
from app01 import models

    current_page = request.GET.get('page')
    # current_page = int(current_page)
    all_count = models.Test01.objects.all().count()  # 数据的总个数
	# 调用分页类
    page_info = PageInfo(current_page, all_count, 10, '/custom.html')

    # 数据库中获取需要的数据
    user_list = models.Test01.objects.all()[page_info.start():page_info.end()]

    return render(request, 'custom.html', {'user_list': user_list, 'page_info': page_info})
