Access joined data in Lucid model

Hi, I’ve got a Lucid model query with joins:

await Label.query()
                    .select('labels.*', 'tasks.*')
                    .join('tasks', 'labels.task_id', 'tasks.id')
                    .where('tasks.taskset_id', taskset.id)
                    .fetch()

How do I access the task data (tasks.*) from within the Label model (e.g. within a computed property accessor on Label)?

Thanks

Gary
