Hello, This is my first attempt at writing a server provider. Any help would be deeply appreciated. I am trying to extend a vendor model located in TCG\Voyager\src\Models\Post I am adding methods to the new model.

I created a service provider in my providers folder named VoyagerpostServiceProvider.php

<?php
namespace App\Providers;
use TCG\Voyager\src\Models\Post;
use Illuminate\Support\ServiceProvider;

class VoyagerpostServiceProvider extends ServiceProvider
{
  public function boot()
  {
  }

  public function register()
  {
    $this->app['post'] = $this->app->share(function($app)
    {
        return new \App\PostTwo(); 
    });
  }
}

 
?>

This is my new model

<?php

namespace App;

//use TCG\Voyager\src\Models\Post; 


class PostTwo extends TCG\Voyager\src\Models\Post
{
    public function authorId()
    {
        return $this->belongsTo(User::class);
    }

    
    
    public function clientId(){
        return $this->belongsTo(\App\Client::class); 
    }
}

I still get an error:

RelationNotFoundException in RelationNotFoundException.php line 20:
Call to undefined relationship [clientId] on model [TCG\Voyager\Models\Post].
