There's nothing to fix. artist_id is giving the ID of the artist
record, not the user record. This is exactly what you've asked Rails to
do.

That might work, or just have a role field in your User model, and only
role "artist" can upload videos.
Or get rid of the distinction altogether, and do something like
class User
def artist?
self.videos.size > 0
end
end
