I have recently upgraded a Laravel 5.1 app to 5.2. This was working fine before but since the upgrade I am experiencing an issue. When I try to delete one of my models I get the following exception:
FatalErrorException in Model.php line 1011:
Class name must be a valid object or a string
The URL I am visiting is:
/admin/roles/delete/4
The route for it is:
Route::get('admin/roles/delete/{id}', ['as' => 'admin.roles.delete', 'uses' => 'Admin\RolesController@destroy']);
The controller code is:
public function destroy($id)
{
$role = Role::find($id);
$role->delete();
Session::flash('message', '<div class="alert alert-success" role="alert">The role has been deleted.</div>');
return redirect(route('admin.roles'));
}
The model code is:
<?php namespace App;
use Zizaco\Entrust\EntrustRole;
class Role extends EntrustRole
{
protected $fillable = ['name', 'display_name', 'description'];
}
It's probably worth mentioning I'm using the Entrust package. This is the content of my entrust config file:
<?php
/**
* This file is part of Entrust,
* a role & permission management solution for Laravel.
*
* @license MIT
* @package Zizaco\Entrust
*/
return [

'role' => 'App\Role',
/*

'roles_table' => 'roles',

'permission' => 'App\Permission',

Looks like Entrust just isn't fully compatible with Laravel 5.2 yet. I've raised this issue on Github and others are having the same problem.
Looks like you may not have your Entrust configuration set up properly.
The method_exists() call on the deleting event in the EntrustRoleTrait would be throwing this exception when you're trying to delete the role and the returned string from the Config::get() call isn't a valid class or object.
https://github.com/Zizaco/entrust/blob/master/src/Entrust/Traits/EntrustRoleTrait.php#L75
Check your configuration and make sure you've set the model name correctly.
After updating to 5.2 you change the config/auth.php
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => App\Models\User::class,
],
// 'users' => [
// 'driver' => 'database',
// 'table' => 'users',
// ],
],
https://github.com/Zizaco/entrust/blob/master/src/Entrust/Traits/EntrustRoleTrait.php#L48
try to replace Entrust/Traits/EntrustRoleTrait.php Config::get('auth.model') on Config::get('auth.providers.users.model')
