django - ImportError:无法导入名称“DjangoFilterBackend”

升级到Django REST framework 3.7后，出现以下错误

  File "/home/jpg/Projects/django2x/sample/views.py", line 24, in <module>
    from rest_framework.filters import DjangoFilterBackend
ImportError: cannot import name 'DjangoFilterBackend'

这是我的看法

from rest_framework.filters import DjangoFilterBackend
from rest_framework import viewsets


class FooViewSet(viewsets.ModelViewSet):
    queryset = Foo.objects.all()
    serializer_class = Foo_Serializer
    filter_backends = (DjangoFilterBackend,)
    filter_fields = ('foo_bar', 'bar_foo')

最佳答案

rest_framework.filters.DjangoFilterBackend在DRF : 3.7中被描述。因此，从DRF 3.7开始，您应该安装django-filter软件包以在视图中使用DjangoFilterBackend。



您可以将< DRF 3.6样式过滤器更新为

from rest_framework import viewsets
from django_filters import rest_framework as filters


class FooViewSet(viewsets.ModelViewSet):
    queryset = Foo.objects.all()
    serializer_class = Foo_Serializer
    filter_backends = (filters.DjangoFilterBackend,)
    filterset_fields = ('foo_bar', 'bar_foo')

注意：在较新版本的django-filter中，filter_fields属性被更改为filterset_fields
