本文實(shí)例講述了Django框架實(shí)現(xiàn)的簡單分頁功能。分享給大家供大家參考，具體如下：
前面一篇《Django開發(fā)的簡易留言板》寫了個(gè)簡單的留言板，如果數(shù)據(jù)量太多的話在一頁顯示就不那么友好了，本文就是做一個(gè)分頁顯示。
代碼在上一篇的基礎(chǔ)上修改。
導(dǎo)入分頁模塊并修改views
#只需修改index函數(shù)即可from django.core.paginator import Paginatordef index(request): messages = models.Message.objects.all() #獲取全部數(shù)據(jù) limit = 10 paginator = Paginator(messages, limit) #按每頁10條分頁 page = request.GET.get('page','1') #默認(rèn)跳轉(zhuǎn)到第一頁 result = paginator.page(page) return render(request, 'guestbook/index.html', {'messages' : result})修改html
