我一直在尝试使用django-filters,但对象没有被过滤。此外,权限在部分更新视图中也无法正常工作。
我有一个Viewset,其中包含基本操作,例如- list(),retrieve(),destroy(),partial_update()以及其他一些操作,并尝试对其应用过滤器。
经过一些研究,我发现由于我通过过滤器创建了查询集,因此我将不得不覆盖get_queryset()方法。然而,那似乎也没有起作用。过滤器只能与ModelViewSet或ListApiView配合使用吗?
ViewSet -
class PostViewSet(viewsets.ViewSet):
"""
The Endpoint to list, retrieve, create and delete Posts.
"""
filter_backends = (DjangoFilterBackend, )
# filterset_class = PostFilter
filter_fields = ('pet_age', 'pet_gender', 'breed')
def get_permissions(self):
if self.action == 'partial_update' or self.action == 'update':
permission_classes = [IsPostAuthor, ]
elif self.action == 'create' or self.action == 'destroy':
permission_classes = [IsAuthenticated, ]
else:
permission_classes = [AllowAny, ]
return[permission() for permission in permission_classes]
def get_queryset(self):
return Post.objects.active() # This is implemented via custom Manager
def list(self, request, *args, **kwargs):
"""
Method for Post listing. It can be accessed by anyone.
"""
serializer = PostListSerializer(self.get_queryset(), many=True, context={"request": request})
return Response(serializer.data)
# REST CODE TRUNCATED
权限 -
class IsPostAuthor(permissions.BasePermission):
"""
Object-level permission to only allow owners of an object to edit it.
"""
def has_object_permission(self, request, view, obj):
if request.user.is_authenticated:
if view.action in ['partial_update', 'update']:
return obj.user.id == request.user.id
return False
return False
后置过滤器 -
class PostFilter(filters.FilterSet):
class Meta:
model = Post
fields = ('pet_age', 'pet_gender', 'breed', )
经理 -
class PostManager(models.Manager):
def active(self):
return self.filter(post_status='Active')
非常感谢您的帮助。
