django中实现分页查询

1. 首先要实现分页查询必须给定俩个参数page(当前页数)和pages(每页显示的数据量,即显示几条数据):
2. 上代码:

from django.core.paginator import Paginator

def select_master(request):
    page=int(request.POST.get('page'))
    pageSize=int(request.POST.get('pageSize'))
    res={}
    master_list=Master.objects.all()        #查询整个Master
    #创建分页对象
    ptr=Paginator(master_list,pageSize)
    
    res['total']=ptr.count
    
    masters=ptr.page(page)
    res['list']=masters
    res['list'] = json.loads(serializers.serialize("json",masters))
    return JsonResponse(res)
