【原】django实现列表分页功能

在view.py里添加分页查询方法：

 from django.http import JsonResponse
 from django.views.decorators.http import require_http_methods
 from django.core import serializers
 4 from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
 import json

 # 分页查询
 def show_page(request):
     page = request.GET.get('page')
     pageSize = int(request.GET.get('pageSize'))
     response = {}
     book_list = Book.objects.all()
     paginator = Paginator(book_list, pageSize)
     response['total'] = paginator.count
     try:
         books = paginator.page(page)
     except PageNotAnInteger:
         books = paginator.page()
     except EmptyPage:
         books = paginator.page(paginator.num_pages)
     response['list'] = json.loads(serializers.serialize("json", books))
     return JsonResponse(response)
