✅ IMPLEMENTASI SELESAI - Admin-Only System

📊 Summary of Changes

Aplikasi Klasifikasi Kematangan Tomat telah diubah menjadi Admin-Only System (bukan public multi-user).

🔧 Changes Made

1. ✅ User Model Updated

File: app/Models/User.php

protected $fillable = [
    'name',
    'email', 
    'password',
    'role',              // ← Added
    'email_verified_at', // ← Added
];

Alasan: Allow role field untuk admin CRUD operations

2. ✅ Database Migration Created

File: database/migrations/2025_02_05_cleanup_users_admin_only.php

Fungsi:

Hapus semua user dengan role 'user'
Set role 'admin' untuk semua user yang tersisa
Prepare database untuk admin-only system

Jalankan:

php artisan migrate

File: resources/views/login.blade.php

Perubahan:

<!-- Lama -->
<p>Halaman ini khusus untuk admin sistem</p>

<!-- Baru -->
<p>Belum punya akun admin? 
   <a href="{{ route('admin.manage-admin') }}">
     Hubungi administrator
   </a>
</p>

Alasan: Direct link ke admin management untuk tambah admin baru

🗄️ Database Structure

Users Table (Admin Only):

- id (INT)
- name (VARCHAR)
- email (VARCHAR) - UNIQUE
- password (VARCHAR) - hashed
- role (VARCHAR) = 'admin' (ALWAYS)
- email_verified_at (TIMESTAMP)
- remember_token (VARCHAR)
- created_at (TIMESTAMP)
- updated_at (TIMESTAMP)

Note: Tidak ada role 'user', semua adalah 'admin'
