Aggregation relationships (two or more) between two tables in laravel 5

I am developing a web app using laravel 5. Now i am having a issue below:

• I have two table users and feedbacks

  • users: id, username, password

  • feedbacks: id, provider, receiver, reviewer, content

• I want to provider, receiver and reviewer is a user. Meaning i will storage user'id into provider, receiver and reviewer.

• In laravel, i only can setup a relationship for model User like: $this->belongsTo('User', 'provider', 'id')

• And i want to receiver and reviewer also have belongsTo relationship

• I thought creating the third table for many to many relationship, but if i do it, i must create two tables for receiver and reviewer.

I need helping to solve this issue without using more queries on controller, thanks for reading.
