Laravel 5.2 Classes do not exist

Question

The problem:

I have an error with my Laravel 5.2 application, where a call for a class method results in Laravel not being able to locate the class.

I run a LAMP-stack.

I have tried various suggestions, with many people stumbling upon namespacing as the solution. I am new to Laravel, so there might be some elemental setup that I have done incorrectly. I have mainly looked into folder ownership and permissions.

I have also experienced this problem when calling a different controller provided by a library. However, I am not certain whether or not describing this problem would just obfuscate the real issue.

My error:

ReflectionException in Route.php line 264: Class App\Http\Controllers\SteamInventory does not exist

My route in /app/Http/routes.php

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

    Route::get('trades', 'SteamInventory@getInventory');

});

My controller in /app/Http/Controllers/SteamInventoryController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;

class SteamInventoryController extends Controller
{
    public function getInventory () {
        return "test";
    }
}

Answer 1

Change this

SteamInventory

To this

In this

Route::get('trades', 'SteamInventory@getInventory');

Answer 2

Change your Route

   Route::get('trades', 'SteamInventory@getInventory');

TO

  Route::get('trades', 'SteamInventoryController@getInventory');
