php - Laravel 5 polymorphic relationship with foreign key -

-

tables:

roles

-id -role

users

-id -role_id

schools

-id (primary, foreign-references id on users)  -other attributes

consultancies

-id (primary, foreign-references id on users)  -other attributes

students

-id (primary, foreign-references id on users)  -other attributes

school, consultancies , students specialization (or generalization?) of users.

in model class, trying establish polymorphic one-to-one relationship. seems straight forward if there had not been roles table , role_id in user table had been string: role.

but structure, how relationships work?
