分页器组件支持保存搜索条件

  1 class Pagination(object):
  2     def __init__(self, current_page, all_count, params,per_page_num=10, pager_count=11):
  3         """
  4         封装分页相关数据
  5         :param current_page: 当前页
  6         :param all_count:    数据库中的数据总条数
  7         :param per_page_num: 每页显示的数据条数
  8         :param pager_count:  最多显示的页码个数
  9 
 10         用法:
 11         queryset = model.objects.all()
 12         page_obj = Pagination(current_page,all_count)
 13         page_data = queryset[page_obj.start:page_obj.end]
 14         获取数据用page_data而不再使用原始的queryset
 15         获取前端分页样式用page_obj.page_html
 16 
 17         示例代码：
 18         current_page = self.request.GET.get("page", 1)
 19         self.page_obj = Pagination(current_page=current_page,all_count=self.queryset.count(),params=self.request.GET)
 20         self.page_queryset = self.queryset[self.page_obj.start:self.page_obj.end]
 21         前台：{{ show_obj.page_obj.page_html|safe }}
 22         """
 23         try:
 24             current_page = int(current_page)
 25         except Exception as e:
 26             current_page = 1
 27 
 28         if current_page <1:
 29             current_page = 1
