I have added a ‘role_id’ to my User model, and also a user_id reference in my ‘office’ model.
In so doing, I need to be able to update those fields when a new User registration is processed - adding the correct role_id, and then adding the new users ID to the office table.
I have no idea how to customize the User registration process so any links, suggestions, examples would be great
