这是我的许可类:
class IsCreationOrFollowOrOwnerOrReadOnly(permissions.BasePermission):
"""
Allow any users to create, get and follow objects. Allow only owners to
PUT, PATCH and DELETE.
"""
def has_permission(self, request, view):
if request.method in permissions.SAFE_METHODS or request.user.is_staff:
return True
if view.action == 'create':
return True
return False
def has_object_permission(self, request, view):
if request.method in permissions.SAFE_METHODS or request.user.is_staff or view.action=='follow':
return True
try:
return obj.owner == request.user
except:
return obj == request.user # If obj Is request.user
要关注对象,您必须使用follow
操作。这是我的观点:
class {ageViewSet(viewsets.ModelViewSet):
queryset = Page.objects.all()
serializer_class = PageSerializer
permission_classes = (IsAuthenticated, IsCreationOrFollowOrOwnerOrReadOnly,)
def perform_create(self, serializer):
serializer.save(owner=self.request.user, location=self.request.user.userextended.location)
@detail_route(methods=['post'])
def follow(self, request, pk=None):
page = self.get_object()
page.users.add(request.user)
return Response(status=status.HTTP_204_NO_CONTENT)
问题是,当我尝试关注某个对象时,它会给我一个403_FORBIDDEN
状态代码。我假设这是因为在has_permission
中,我必须添加以下行:
if view.action=='follow':
return True
但即使我添加该行,当所有者试图将其投放到他自己的对象时,我会收到403_FORBIDDEN
错误(这可能是因为我的has_permission
方法中我没有if view.action == 'update': return True
但是PUT,PATCH和DELETE都依赖于对象本身(if obj.owner == request.user
)所以如何在允许任何用户使用FOLLOW对象的同时正确地允许用户进行PUT,PATCH和DELETE(FOLLOW也是一个对象级权限,因此将其置于has_permission
对我来说没有意义,因为它与对象有关。)
答案 0 :(得分:0)
您无需覆盖has_permission
。只需覆盖has_object_permission
即可:
def has_object_permission(self, request, view, obj):
if request.method in permissions.SAFE_METHODS or request.user.is_staff or obj.owner == request.user:
return True
if request.method=='POST':
return True
return False
这样,所有者和员工可以执行任何操作。但是用户只能获取,发布和关注。
