Controller gives error "Target class does not exist"

Time：10-07

I have a Laravel 8 project. I changed Controllers file location in project. I did almost all but only two Controllers getting errors. While changing the file locations, it seems that I have updated every necessary part, but it gives an error that I do not understand. It even shows the wrong location of the Controller in the error it gives. I leave a screenshot of the error below, you can see it from there.

enter image description here

The full file location of PromotionalCodeController is as follows: App\Http\Controllers\Admin\PromotionalCodeController

Although its location is like this, the error also shows this location differently.

What am I missing?

CodePudding user response：

I played around with your setup a little: https://github.com/ancarofl/laravel-tests/commits/controller-does-not-exist. I can't reproduce the error but maybe it helps.

With your current web.php you'd have to wrap the controller name in qutoation marks:

Route::resource('promotional-codes', 'App\Http\Controllers\Admin\PromotionalCodeController');

Your original also works for me, barring the prefix and middlware:

Route::resource('promotional-codes', PromotionalCodeController::class);

My test project is in Laravel 9 but for Laravel 8 also have a look at
Hopex Development's comment regarding commenting protected $namespace = 'App\\Http\\Controllers';. I imagine the other controllers wouldn't work either if that were the problem though.

If nothing works please provide the output of php artisan route:list.

CodePudding user response：

It was hard, but I finally solved it out guys. In web.php I made the route of PromotionalCodeController as follows. I still can't understand the logic because Laravel 8's documentation does not say anything like that. So I think this is a bug with the resourse method in Laravel 8. But it was solved in the end, and that was the important thing.

I solved it like this:

The first state

Route::resource('promotional-codes', PromotionalCodeController::class)->names('promotionalcodes');

The second state

Route::namespace("\\")->group(function(){
            Route::resource('promotional-codes', PromotionalCodeController::class)->names('promotionalcodes');
        });

web.php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\Admin\{
    AdminController,
    AwsTranscoderController,
    AwsTranscribeController,
    CategoryController,
    ContentController,
    Controller,
    CourseController,
    CreatorApplicationController,
    CreatorController,
    DevController,
    DynamicLinkController,
    FetchDataOutside,
    HomeController,
    LearnBiteController,
    NotificationsController,
    NotionApiController,
    PayoutController,
    PromotionalCodeController,
    RecomendationEngineController,
    RequestPayoutController,
    SubscriberController,
    TagController,
    UserTagController,
};

Route::prefix('admin-panel')->group(function(){

    Route::group(['middleware' => 'auth'], function(){ 

        Route::namespace("\\")->group(function(){
            Route::resource('promotional-codes', PromotionalCodeController::class)->names('promotionalcodes');
        });

If anyone has the same problem, I think they can fix it this way.
