将def list（）添加到模型视图集时，Django rest框架过滤器和搜索不起作用 [英] Django rest framework filters and search not working when def list() is added to model viewsets

问题描述

我正在研究用Django rest框架编写的API。我在ModelViewSet中添加了搜索过滤器和排序过滤器，并且运行良好。

I am working on API written in Django rest framework. I have added Search filters and ordering filters in my ModelViewSet and were working fine.

class bookviewset(ModelViewSet):

    queryset = Book.objects.all()
    serializer_class = book_serializer
    filter_class = bookfilter
    filter_backends = ( django_filters.rest_framework.DjangoFilterBackend,filters.OrderingFilter,filters.SearchFilter)
    ordering_fields = ('created_at', 'id','price_ids__price',)
    search_fields = ('name', 'description', 'tag_ids__tag_name', 'category_ids__category')

但是，当我覆盖 def list（self，request，* args，** kwargs）：在Modelviewset中，所有过滤器均已停止工作。

But, When I override def list(self, request, *args, **kwargs): inside Modelviewset, all the filters have stopped working.

有办法再次启用所有过滤器吗？

Is there a way to enable all the filters again?

谢谢。

推荐答案

您必须使用 filter_queryset 方法手动过滤查询集。因此，将此行添加到您的列表方法中。

You must manually filter your queryset using this filter_queryset method. So add this line to your list method.

def list(self, request, *args, **kwargs):
    # fetch qs
    qs = self.filter_queryset(qs)
    # etc
