如何在Django Rest Framework上使用普通Filter和SearchFilter？

Question

我正在使用DRF(Django Rest Framework).

我声明了一个ModelViewSet,现在我想在其上添加过滤器.

class GoodsViewSet(viewsets.ModelViewSet):
    class Filter(FilterSet):    
        class Meta:
            model = m.Goods

    filter_class = Filter
    filter_backends = (SearchFilter, Filter)
    search_fields = ['name',]
    queryset = m.Goods.objects.all()
    serializer_class = s.GoodsSerializer

看到我声明了一个Filter子类并将其应用于:

filter_class = Filter

在我添加行之前,它在开始时工作:

filter_backends = (SearchFilter, Filter)
search_fields = ['name',]

这是由医生告诉的.

现在,在filter_class跳过法线时应用搜索过滤器.

一句话,他们无法一起工作.

如何解决这个问题？

最后,我发现我们应该filter_backends一起指定两个:

from rest_framework.filters import SearchFilter
from django_filters.rest_framework import DjangoFilterBackend

class GoodsViewSet(viewsets.ModelViewSet):
    class Filter(FilterSet):    
        class Meta:
            model = m.Goods

    filter_class = Filter
    filter_backends = (SearchFilter, DjangoFilterBackend)
    search_fields = ['name',]
    queryset = m.Goods.objects.all()
    serializer_class = s.GoodsSerializer

或者我们可以忽略filter_backends特定ViewSet类的字段,但全局应用于settings.py:

REST_FRAMEWORK = {
    # ... other configurations
    'DEFAULT_FILTER_BACKENDS': (
        'rest_framework.filters.SearchFilter',
        'django_filters.rest_framework.DjangoFilterBackend',
    ),
}

这样,View filter_class和search_fieldsView可以同时在ViewSet上使用.
