定义一个模块

from django.http.request import QueryDict class Pagination: def __init__(self, page_num, all_count,params=None, per_num=10, max_show=11): """ :param page_num: 当前的页码数 :param all_count: 总数据量 :param per_num: 每页显示的数据条数 :param max_show: 最大显示页码数 :param self.total_page_num: 总页码数 :param self.page_start: 起始页码数 :param self.page_end: 终止页码数 """

后端引用

page = Pagination(request.GET.get('page', '1'), all_customer.count(), request.GET.copy(), 2) 

?params=None
?request.GET.copy() 

#按照def __init__(self, page_num, all_count,params=None, per_num=10, max_show=11): 对应传参

前端引用

{{ page_html|safe }}  #自己加上自己喜欢的样式
