Assigning records to many to one relations

[ibb2]

I am trying to understand how to set the a many to one relation. As I understand it for 1 to 1 relations the following would be
await database.get('comments').create(comment => { comment.author.set(someUser) // ... }) .
If I was to want to add many would users, say if this relation was hypothetically many to one, with comments allowing for many users, would it simply be
await database.get('comments').create(comment => { comment.author.set(someUser) comment.author.set(someUser2) comment.author.set(someUser3) })
Thanks.
