"User Model" functions in Laravel 5 don't work - laravel

Question

I migrate from laravel 4 to laravel 5. I modified User Model to make it compatible to laravel 5 User Model. The User model in Laravel 4 is like that:
use Illuminate\Auth\UserInterface;
use Illuminate\Auth\Reminders\RemindableInterface;
class User extends Eloquent implements UserInterface, RemindableInterface {
// some model relation functions..
...
public function getLocationId()
{
return $this->location_id;
}
}
I modified it and the new User model is like that now:
namespace App\Models;
use Illuminate\Auth\Authenticatable;
use Illuminate\Auth\Passwords\CanResetPassword;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;
use Illuminate\Database\Eloquent\Model as Eloquent;
class User extends Eloquent implements AuthenticatableContract, CanResetPasswordContract {
use Authenticatable, CanResetPassword;
// some model relation functions (some changes for namespace)
...
public function getLocationId()
{
return $this->location_id;
}
}
However, getLocationId method is now problematic. The following line results in an error.
$auth_location_id = Auth::user()->getLocationId();
This is the error:
BadMethodCallException in Builder.php line 2508:
Call to undefined method Illuminate\Database\Query\Builder::getLocationId()
How can I make the method compatible to laravel 5? Thanks..
Update:
$auth_location_id = Auth::user()->getLocationId; works but returns empty!!
The line below works properly.
$auth_user_id = Auth::user()->getAuthIdentifier();

By my understanding, and short experience with Laravel, all I do is just to use:
use Illuminate\Foundation\Auth\User as Authenticatable;
Then have my Model as:
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
public function getLocationId()
{
return $this->location_id;
}
}
So I may be safe to assume, at least because it works for me that all those contracts has be extended in the facade called when ....\User is used.
PS: this is just an illustration of how I currently use it in Laravel 5.2.*.
Hope this can help or lead you to the solution :)
