resolve func for Reverse Foreign Key Set do not work

[Rainshaw]

Hello, I have two models:

class Department(models.Model):
    department = models.CharField(max_length=100)
class User(models.Model):
    username = ...
    department = ForeignKey(to=Department, on_delete=models.DO_NOTHING,)

And I define two types:

class DepartmentType(DjangoObjectType):
    class Meta:
        model = Department

    def resolve_user_set(root, info, **kwargs):
        if info.context.user.is_authorization:
            return self.user_set
        return None

class UserType(DjangoObjectType):
    class Meta:
        model = User


class Query(graphene.ObjectType):
    departments = DjangoFilterConnectionField(DepartmentType)

Then I use the query without authorization:

query{
departments{
    edges{
      node{
        id
        department
        userSet{
          edges{
            node{
              id
              name
            }
          }
        }
      }
    }
  }
}

but the resolve func run without taking effact(with print func I can see that it return None). The response each have all users.

{
  "data": {
    "departments": {
      "edges": [
        {
          "node": {
            "id": "RGVwYXJ0bWVudFR5cGU6MQ==",
            "userSet": {
              "edges": [
                {
                  "node": {
                    "id": "VXNlclR5cGU6MQ=="
                  }
                },
                {
                  "node": {
                    "id": "VXNlclR5cGU6Mg=="
                  }
                },
                {
                  "node": {
                    "id": "VXNlclR5cGU6Mw=="
                  }
                }
              ]
            }
          }
        },
        {
          "node": {
            "id": "RGVwYXJ0bWVudFR5cGU6Mg==",
            "userSet": {
              "edges": [
                {
                  "node": {
                    "id": "VXNlclR5cGU6MQ=="
                  }
                },
                {
                  "node": {
                    "id": "VXNlclR5cGU6Mg=="
                  }
                },
                {
                  "node": {
                    "id": "VXNlclR5cGU6Mw=="
                  }
                }
              ]
            }
          }
        }
      ]
    }
  }
}

I have tried #1111 and #1133, but they all not work.... what should the resolver func return? or is this a bug?

@RainshawGao hey there! could you please provide more info on what is_authorization actually is?
In case the user is not "authorized", I believe the correct return type should be an empty queryset not None i.e in your case: User.objects.none()

Maybe you are right but I'll not test it, for I didn't use this project any more, so close this.
