PHP laravel class not found. How can I use namespaces to fix this?

Question

I'm using the Laravel framework and have a directory of the following structure:

models 
  Statistic.php

presenters
  StatisticPresenter.php

In my models/Statistic class, I'm trying to access a present method which calls a protected property which then references my presenter:

protected $presenter = 'presenters\StatisticPresenter';

public function present() {
    return new $this->presenter($this); 
}

Yet, this returns the error: Class 'presenters\StatisticPresenter' not found. I realize this is a namespacing error of some sort, and I've tried watching a few videos on how it works, but I simply can't wrap my head around it. I have already added my presenter folder to my composer.json file. For example, adding this to the top of my Statistic model does not work:

use presenters\StatisticPresenter;

How can I fix this?

If you haven't already, run composer dump-autoload. You can also try adding a backslash in at the beginning: '\presenters\StatisticPresenter' — lukasgeiter

Do the followings;

Mark your namespace in StatisticPresenter.php ? (at the top of file "namespace presenters;")
Add PSR-4 class map to your composer

{ "autoload": { "psr-4": { "presenters\\": "app/presenters/" } } }

run "composer dump-autoload" once and you wont need to run this command again for the "presenters" namespace if you add new classes into "app/presenters/ folder"
Test your class with "use presenters/StatisticPresenter;"
If you can access your class you dont need to change your code your present() function will be valid
