Sorting not working

def int_timestamp():
    return int(time.time())

class UserActivity(TimestampedModel, Base, DictModel):
    __tablename__ = 'user_activities'
    id = Column(Integer, primary_key=True)
    user_id = Column(Integer, ForeignKey("user.id", ondelete='SET NULL'))
    username = Column(String())
    timestamp = Column(Integer, default=int_timestamp)

class UserActivityModel(SQLAlchemyObjectType):
    class Meta:
        model = UserActivity
        only_fields = ()
        exclude_fields = ('user_id',)
        interfaces = (relay.Node,)

class Query(ObjectType):
    list_user_activities = SQLAlchemyConnectionField(
        type=UserActivityModel,
        sort=UserActivityModel.sort_argument()
    )

    def resolve_list_user_activities(self, info: ResolveInfo, sort=None, first=None, after=None, **kwargs):
        # Build the query
        query = UserActivityModel.get_query(info)
        query = query.filter_by(**kwargs)
        return query.all()

graphql_app = GraphQLApp(schema=Schema(query=Query))

My query in GQL:

query {
	listUserActivities(first: 3, sort: TIMESTAMP_DESC) {
		edges {
			node {
				username
				timestamp
			}
		}
	}
}

The result:

{
	"data": {
		"listUserActivities": {
			"edges": [
				{
					"node": {
						"username": "[e-mail]",
						"timestamp": 1644321703
					}
				},
				{
					"node": {
						"username": "[e-mail]",
						"timestamp": 1644334763
					}
				},
				{
					"node": {
						"username": "[e-mail]",
						"timestamp": 1644344156
					}
				}
			]
		}
	}
}

What’s really strange is the first argument appears to apply a limit to the result, but the sort argument appears to just be swallowed and unused. Switching to TIMESTAMP_ASC produces the same result. I’m trying to find examples online to help with this. What am I doing wrong or what can i try here?

I’m using 2.3.0

Great to hear, I’m closing this issue now. If further problems occur, feel free to reply. Since I saw the attempt to apply filtering to your queries, I suggest looking into this library, before you put in too much duplicate work into providing basic custom filters: https://github.com/art1415926535/graphene-sqlalchemy-filter

It’s currently inactive but provides a lot of filtering functionality for graphene-sqlalchemy 2.0. For graphene-sqlalchemy 3, we are currently working on a custom implementation!

That worked! Thank you so much.
