In the Laravel Basics course and the lesson 'Using Controllers to Return Views' I created the AppController just like in the tutorial and changed the route to reference it again like in the tutorial, however, when I go to the web page, I get a Target Class [AppController] does not exist error. the controller code and the route are given below:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class AppController extends Controller { public function index() { return view('welcome'); }
}
route code:
Route::get('/', 'AppController@index')
I have MAMP installed and am using the default port 8888. Valet is also installed and the directory of my project is parked so that I start the web page with treehouse.test. Just to be sure it wasn't Valet that was a problem, I also fired up the artisan server and attempted to see the webpage through localhost:8000.
If I remove the controller and return the route to have the function statement I can view the welcome page no problems, but as soon as I put the AppController in I get the error.

6,081 PointsI believe this is something that has changed in Laravel 8. This video series was made with an earlier version. Adapting the example from the Laravel 8 Docs, given here: https://laravel.com/docs/8.x/routing#basic-routing
This works for me:
Route::get('/', [AppController::class, 'index']);

In this file routes/web.php file
I had to use this Route Statement: Route::get('/', 'App\Http\Controllers\AppController@index');
And it worked. Thank you for that Mike! Although it would be helpful for an update and explanation of why it works

Treehouse TeacherHi, Mike Womack! I feel like there's not quite enough information to give you a definitive answer here. It could be something as simple as the file structure or possibly even the autoloading. Do you happen to have this pushed up to GitHub anywhere where I could take a look?
Let me know

13,672 PointsJennifer, Thanks for your response. I have since got it working, although I am not sure exactly why. I found an answer in StackOverflow that helped at https://stackoverflow.com/questions/63807930/target-class-controller-does-not-exist-laravel-8. It looks like something changed in laravel 8. It talks about something to do with Namesapce and the RouteServiceProvider. The bottom line is I added the full path including the Namespace "App\Http\Controllers\AppController@index' to the route statement and it worked. Thanks

10,827 PointsI too had to use the Stack overflow that Mike is referring to. Seems the course needs a note adding to update.
Had to use the full file path for the AppController.
