from rest_framework.views import APIView
from rest_framework.pagination import PageNumberPagination

class ProductList(APIView, PageNumberPagination):
    # number of items per page by default
    page_size = 1000
    # max number of items per page
    max_page_size = 1000

    def get_queryset(self):
        product_sync_ts = self.request.GET.get('product_sync_ts', None)
        if product_sync_ts:
            products = GrProduct.objects.filter(update_ts__gt=product_sync_ts)
            return self.paginate_queryset(products)

        raise APIException400(request, {'details': "Bad Request"})

    def get(self, request):
        products = self.get_queryset()
        serializer = SyncedProductSerializer(instance={'products': products})
