Laravel 8: Array to string conversion while calling route:list

Question

I have a resource controller which is ArticleController and I want to call this controller in web.php, so I coded:

use App\Http\Controllers\Admin\PanelController;
use App\Http\Controllers\Admin\ArticleController;

Route::namespace('Admin')->prefix('admin')->group(function(){
  Route::get('/admin/panel', [PanelController::class, 'index']);
  Route::resource('articles', [ArticleController::class]);
});

Then I tried the command php artisan route:list to check the routes but I get this error message:

ErrorException

Array to string conversion

So why this error occurs, how can I fix it?

Solution

Route::resource is expecting a string for the second argument, not an array.

Route::resource('articles', ArticleController::class);

Remove the call to namespace for the group, you don't need any namespace prefix because you are using the Fully Qualified Class Name, FQCN, to reference the Controllers.

Route::prefix('admin')->group(function () {
    Route::get('/admin/panel', [PanelController::class, 'index']);
    Route::resource('articles', ArticleController::class);
});

[Admin]

I removed the array around the Controller, but now it says: Target class [Admin\App\Http\Controllers\Admin\ArticleController] does not exist.

Because you're adding a namespace before any controller being defined in the route file. You can check namespace in the RouteServiceProvider or the group of route that you've defined

@ruwroveajaic , i had the same issue recently, this can be fixed by putting the entire class path in a string like Route::resource('articles', 'App\Http\Controllers\ArticleController'); assuming your controller is in a similar path, so you change the path accordingly.
