- from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
- def SelfPaginator(request,List,Limit):
- '''分页模块,用法:
- 1.view中引入：
- ex:from website.common.CommonPaginator import SelfPaginator
-
- 2.SelfPaginator需要传入三个参数
- (1).request:获取请求数据
- (2).List:为需要分页的数据（一般为*.objects.all()取出来数据）
- (3).Limit:为每页显示的条数
- ex:lst = SelfPaginator(request,mList, 5)
-
- 3.view需要获取SelfPaginator return的lst，并把lst返回给前端模板
- ex:kwvars = {'lPage':lst,}
-
- 4.前端需要for循环lPage也就是lst读取每页内容
- ex:{% for i in lPage %} ... {% endfor %}
-
- 5.模板页引入paginator.html
- ex:{% include "common/paginator.html" %}
- '''
- paginator = Paginator(List, int(Limit))
- page = request.GET.get('page')
- try:
- lst = paginator.page(page)
- except PageNotAnInteger:
- lst = paginator.page(1)
- except EmptyPage:
- lst = paginator.page(paginator.num_pages)
- return lst
- if __name__=='__main__':
- rList = User.objects.all()
- lst = SelfPaginator(request,rList,20)
