Spatie/Laravel-權限：虛擬數據錯誤

Question

我將 Laravel 與 spatie/laravel-permission 包一起使用，如本教程中所述。 但是，當我嘗試創建虛擬數據時，它返回以下錯誤Spatie\\Permission\\Exceptions\\RoleDoesNotExist ：沒有名為Admin角色。

下面是生成虛擬數據的類。

class DatabaseSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        // Ask for db migration refresh, default is no
        if ($this->command->confirm('Do you wish to refresh migration before seeding, it will clear all old data ?')) {
            // Call the php artisan migrate:refresh
            $this->command->call('migrate:refresh');
            $this->command->warn("Data cleared, starting from blank database.");
        }

        // Seed the default permissions
        Permission::firstOrCreate(['name' => 'Administer roles & permissions', 'guard_name' => 'isAdmin']);


        $this->command->info('Default Permissions added.');

        // Confirm roles needed
        if ($this->command->confirm('Create Roles for user, default is admin and user? [y|N]', true)) {

            // Ask for roles from input
            $input_roles = $this->command->ask('Enter roles in comma separate format.', 'Admin,User');

            // Explode roles
            $roles_array = explode(',', $input_roles);

            // add roles
            foreach($roles_array as $role) {
                $role = Role::firstOrCreate(['name' => trim($role), 'guard_name' => 'isAdmin']);

                if( $role->name == 'Admin' ) {
                    // assign all permissions
                    $role->syncPermissions(Permission::all());
                    $this->command->info('Admin granted all the permissions');
                } else {
                    // for others by default only read access
                    $role->syncPermissions(Permission::where('name', 'LIKE', 'view_%')->get());
                }

                // create one user for each role
                $this->createUser($role);
            }

            $this->command->info('Roles ' . $input_roles . ' added successfully');

        } else {
            Role::firstOrCreate(['name' => 'User']);
            $this->command->info('Added only default user role.');
        }

        // now lets seed some posts for demo
        $this->command->info('Some Posts data seeded.');
        $this->command->warn('All done :)');
    }

    /**
     * Create a user with given role
     *
     * @param $role
     */
    private function createUser($role)
    {
        $user = factory(User::class)->create();
        $user->assignRole($role->name);

        if( $role->name == 'Admin' ) {
            $this->command->info('Here is your admin details to login:');
            $this->command->warn($user->email);
            $this->command->warn('Password is "secret"');
        }
    }
}

有什么想法可以解決嗎？

Answer 1

你需要跑

php artisan cache:forget spatie.permission.cache

使用角色或權限之前

Answer 2

我通過更改 config/auth.php 文件中的守衛順序修復了這個錯誤：

這是默認的

    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
        'api' => [
            'driver' => 'jwt',
            'provider' => 'users',
        ],
    ],

這就是我現在所擁有的

    'guards' => [
        'api' => [
            'driver' => 'jwt',
            'provider' => 'users',
        ],
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
    ],

我發現當我將默認防護更改為“api” （默認設置為“web” ）時出現此錯誤。

當您在不更改順序的情況下播種角色時，它會將guard_name 正確設置為“api”，但是當它想將這些角色應用於用戶時，它可能會使用“web” guard。

如果您使用的是默認防護，但仍然收到此錯誤，請嘗試在角色播種器中設置 guard_name 字段，如下所示

Role::create(['name' => 'admin', 'guard_name' => 'web']);

由 Spatie/Laravel-permission 引起的此問題還將模型類型存儲在 db 中，並將權限放在 BackpackUser 或 User 模型上。

請參閱此鏈接以供參考：

https://github.com/Laravel-Backpack/PermissionManager/issues/193]

該解決方案是在 2019 年底從 tabacitu 添加的：

https://backpackforlaravel.com/docs/4.0/base-about#have-both-regular-users-and-admins

基本上你需要添加中間件，或者在 User 上添加 is_admin 列或者使用 tabacitu 提供的中間件
