Laravel DB query builder results to populate foreign keys

I am a nodejs developer an use waterline ORM in which after selecting data through db query builder we can call a function of populate() and the resultant is if we have an entry in database with some foreign key, it automatically replaces id with the object of the relationship. I wanted to know if we can do the same in laravel ORM.

Example

Without populate()

{
  "id":"1",
  "content":"abc",
  "user":"1"
}

With populate()

{
  "id":"1",
  "content":"abc",
  "user": {
    "id":1,
    "name":"john",
    "email":"someone@example.com"
  }
}

Thank you for helping.
