自定义分页器

• 后端

  book_queryset=models.book.objects.all()#你想要分页展示的数据
  
  current_page=request.GET.get('page',1)#获取当前页
  
  all_count=book_queryset.count()#看一共有多少条数据
  
  page_queryset=book_queryset[page_obj.start:page_obj.end]
  
  return render (request.'index.html',locals())

• 前端

  {%  for book in page_queryset %}   
    <p>{{book}}</p>`
  
  {% endfor %}
  
  
  
  {{page_obj.page_html|safe}}告诉这是安全的可以读取
