PHP Error: Class 'Course' not found in Psy Shell code on line 1

After following all the steps in the video. Everything works untill I get to Course::all(); in Tinker, where I'm presented with: "PHP Error: Class 'Course' not found in Psy Shell code on line 1".

I've tried to find an answer online, but no luck so far. Things I've tried:

  • Changing the use App\Course; to App\Models\Course;
  • "composer dump-autoload"
  • Running migrate and db:seed again.
  • Deleting the database and creating a new one.
  • Restore a back-up and going through all the actions in this course again

I's there anything I might be missing? I'm running Laravel 8.18.1

I seemed to have fixed this issue by adding use App\Models\Course; to AppController.php on Laravel version 8.

yes, it is fixed by changing 'App\Course' with 'App\Models\Course', but if still not working, please exit Tinker and run composer dump-autoload, then enter tinker again: 'php artisan tinker' and try 'Course::all()' again.

I'm using Laravel 10.9.0

Hi there, Marco Claassen! It seems like you might have missed this instruction step as you are running a different and non-LTS version of Laravel.

Hope this helps! :sparkles:
