I am changing my File-model to go from one to many to be a one to many polymorphic relation. Before only my User-model could have a file but now my model Guest will also be able to have a file.
So before I had a column in the file table named user_id I have renamed that one following the pattern here: https://laravel.com/docs/7.x/eloquent-relationships#many-to-many-polymorphic-relations
So it is now named fileable_id.
In addition to the renaming I have added a column named fileable_type. I now want to backfill that column so everything existing points on the User-model. What should I write in that column?
I have tried App\User and User without success.
