I am currently working on pagination in Django restful framework. I am successfully done with pagination. but the problem I am facing is that "JSON response does not include information about total pages in my query and other information like total records etc". how can I include this information in my response. my view.py is

from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
#######################View all mobiles
@api_view(['GET'])
def getAll_Mobiles(request):
    try:
        Mobile_all = Mobile.objects.all()
        paginator = Paginator(Mobile_all, 10)

        page = request.GET.get('page')
        try:
            users = paginator.page(page)
        except PageNotAnInteger:
            users = paginator.page(1)
        except EmptyPage:
            # If page is out of range (e.g. 9999),
            # deliver last page of results.
            users = paginator.page(paginator.num_pages)
        serializer_context = {'request': request}
        serializer = Mobile_Serializer(users,many=True,context=serializer_context)
        return Response(serializer.data)
    except Mobile.DoesNotExist:
        return Response(status=status.HTTP_404_NOT_FOUND)

，我的API返回URL更改页面上的记录.但它没有给我回复信息.任何人都可以告诉我如何在响应中包含此信息.我将对此表示感谢.

and my API returns record on changing page in URL. but it does not give me response information. Can anybody please tell me how to include this information in response. I will be very thankful for this favour.

推荐答案

       if serializer.data["hasPagination"]:
            paginator = Paginator(result_serializer.data, settings.PAGE_SIZE)
            page = request.GET.get('page', 1)
            result = paginator.get_page(page)
            return Response(data={
                'results': result.object_list,
                'total_records': paginator.count,
                'total_pages': paginator.num_pages,
                'page': result.number,
                'has_next': result.has_next(),
                'has_prev': result.has_previous()
            }, status=status.HTTP_200_OK)
