Ein User kann mehrere Hobbys haben:

Hobby.php

namespace Model;
 
use Illuminate\Database\Eloquent\Model as Eloquent;
 
class Hobby extends Eloquent
{
 
    public $table = 'hobbies';
 
    public function users()
    {
        return $this->hasMany('\Model\User');
    }
}

users.php

namespace Model;
 
use Illuminate\Database\Eloquent\Model as Eloquent;
 
class User extends Eloquent
{
 
    public function hobbies()
    {
        return $this->belongsToMany('\Model\Hobby');
    }
}
