Django rest framework Django Rest框架，列表路由操作的自定义页面大小

我有一个路线列表：

    @list_route(methods=['get'])
    def bought(self, request):
        bought_photos = Photo.objects.filter(is_bought=True)

        page = self.paginate_queryset(bought_photos)
        if page is not None:
            serializer = self.get_serializer(page, many=True)
            return self.get_paginated_response(serializer.data)
        serializer = self.get_serializer(bought_photos, many=True)
        return Response(serializer.data)

如何仅为列表路径而不是其ModelViewSet设置自定义页面大小

解决方案

1） 创建自定义分页类

from rest_framework.pagination import PageNumberPagination

class CustomPagination(PageNumberPagination):
    page_size = 10000
    page_size_query_param = 'page_size'

2） 编辑路线代码列表：

   @list_route(methods=['get'])
   def bought(self, request):
        bought_photos = Photo.objects.filter(is_bought=True)
        paginator = CustomPagination()

        page = paginator.paginate_queryset(bought_photos, request)
        if page is not None:
            serializer = self.get_serializer(page, many=True)
            return paginator.get_paginated_response(serializer.data)
        serializer = self.get_serializer(bought_photos, many=True)
        return Response(serializer.data)

我认为以下代码应该足够了：

@list_route(methods=['get'], pagination_class=CustomPagination)
def bought(self, request):
    bought_photos = Photo.objects.filter(is_bought=True)

    page = self.paginate_queryset(bought_photos)
    if page is not None:
        serializer = self.get_serializer(page, many=True)
        return self.get_paginated_response(serializer.data)
    serializer = self.get_serializer(bought_photos, many=True)
    return Response(serializer.data)

在“装饰者可以额外获取额外的参数，这些参数将仅为路由视图设置。例如…”一文中，我很惊讶地看到一些非常高级的主题和框架的隐藏特性的伟大答案。很遗憾，这个答案没有得到尊重。只需一句话：

page

应该是

list

类型，所以它不能是

None

，所以它将始终输入if子句。如果列表为空，则不应输入If子句，因此条件最好为

If页面：

。或者我有什么不对劲？
