【原】django实现列表分页功能

在view.py里添加分页查询方法：

 1 from django.http import JsonResponse
 2 from django.views.decorators.http import require_http_methods
 3 from django.core import serializers
 4 from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
 5 import json
 6 
 7 # 分页查询
 8 def show_page(request):
 9     page = request.GET.get('page')
10     pageSize = int(request.GET.get('pageSize'))
11     response = {}
12     book_list = Book.objects.all()
13     paginator = Paginator(book_list, pageSize)
14     response['total'] = paginator.count
15     try:
16         books = paginator.page(page)
17     except PageNotAnInteger:
18         books = paginator.page(1)
19     except EmptyPage:
20         books = paginator.page(paginator.num_pages)
21     response['list'] = json.loads(serializers.serialize("json", books))
22     return JsonResponse(response)
