以下是一個例子：

from django.core.paginator import Paginator


def log(rq):
    logs = LogInfo.objects.all().order_by('-create_time')
    page = int(rq.GET.get('page', 1))
    pe = 4
    pf = 5
    pview = pe + pf + 1
    try:
        p = Paginator(logs, 10)  //每頁顯示10條。
        if page <= 0:
            page = 1
        if page > p.num_pages:
            page = p.num_pages
        num_pages = p.num_pages //總頁數
        part = p.page(page)  //第 page 頁的內容
        pagelist = part.object_list  //第 page 頁的內容的列表
        if part.has_previous():
            pre_num = part.previous_page_number()  //第 page 頁的前一頁
        else:
            pre_num = 0
        if part.has_next():
            next_num = part.next_page_number()  //第 page 頁的後一頁
        else:
            next_num = 0
        if page > pf:
            page_range = p.page_range[page - pf - 1:page + pe]
        else:
