 10 # latest_article_list = Article.objects.order_by(‘update‘)[:5]
 11 # cOntext= {‘latest_article_list‘: latest_article_list}
 12 # return render(request, ‘blog/index.html‘,context)
 13 article_list = Article.objects.all().order_by(‘cre_date‘)
 14 paginator = Paginator(article_list,2) #show 2 articles per page
 15
 16 page = request.GET.get(‘page‘)
 17
 18 try:
 19 articles = paginator.page(page)
 20 except PageNotAnInteger:
 21 #The page number is not an integer, return to the first page.  
 22 articles = paginator.page(1)
 23 except EmptyPage:
 24 articles = paginator.page(paginator.num_pages)
 25
 26 return render(request, 'blog/index.html', {  'articles': articles})

paginator is a paging instance, page is the page number parameter passed by the link to the backend, and articles is an instance of each page.

In this example, the paginator divides all articles (article_list) into three pages according to two sections per page. page is the page number requested by the front end. Articles are the specific articles (2 articles) within the page number returned based on the requested page number.

For details on the properties and methods of paginator and articles, please see the documentation: https://docs.djangoproject.com/en/1.8/topics/pagination/

Front-end code:

 1 
  2 <nav>
  3 <div class="pagination pagination-right">  
  4 <ul >
  5 <li>
  6  {% if articles.has_previous %}
  7 <a href="?page={{ articles.previous_page_number }  }" class="active">«</  a>
  8  {% endif %}
  9  {% if not articles.has_previous %}
 10 <a href="" >  «a>
 11  {% endif %}
 12 </li>
 13
 14 <li>
 15  {% for i in articles.paginator.page_range %}
 16 <li {% if articles.number ==   i %}class="active"{% endif %}>
 17 <a href="?page={{ i }}"  >{{ i }}
 18
 19 </a>
 20 </li>
 21  {% endfor %}
 22 </li>
 23
 24 <li>
 25  {% if articles.has_next %}
 26 <a href="?page={{ articles.next_page_number }  }" >»</a>
 27  {% endif %}
 28  {% if not articles.has_next %}
 29 <a href="" >  »</a>
