+# Hướng dẫn thêm Enum mới
+
+## Tổng quan
+
+Hệ thống sử dụng PHP Enums với i18n support. Khi cần thêm giá trị enum mới (Service Type, Contract Type, v.v.), chỉ cần cập nhật 3 chỗ.
+
+## Cấu trúc Enum hiện có
+
+```
+app/Enums/
+├── ContractStatus.php   # Trạng thái hợp đồng
+├── ContractType.php     # Loại hợp đồng
+├── HandoverStatus.php   # Trạng thái bàn giao
+└── ServiceType.php      # Loại dịch vụ
+```
+
+## Ví dụ: Thêm Service Type mới
+
+Giả sử cần thêm loại dịch vụ "Bảo trì định kỳ" (maintenance).
+
+### Bước 1: Thêm case vào Enum
+
+**File:** `app/Enums/ServiceType.php`
+
+```php
+enum ServiceType: string
+{
+    case MANAGEMENT_FEE = 'management_fee';
+    case GRATITUDE = 'gratitude';
+    case SELF_BUSINESS = 'self_business';
+    case MAINTENANCE = 'maintenance';  // ← THÊM MỚI
+
+    public function label(): string
+    {
+        return match ($this) {
+            self::MANAGEMENT_FEE => __('enums.service.management_fee'),
+            self::GRATITUDE => __('enums.service.gratitude'),
+            self::SELF_BUSINESS => __('enums.service.self_business'),
+            self::MAINTENANCE => __('enums.service.maintenance'),  // ← THÊM MỚI
+        };
+    }
+
+    public function color(): string
+    {
+        return match ($this) {
+            self::MANAGEMENT_FEE => 'info',
+            self::GRATITUDE => 'success',
+            self::SELF_BUSINESS => 'warning',
+            self::MAINTENANCE => 'primary',  // ← THÊM MỚI
+        };
+    }
+
+    // options() tự động lấy tất cả cases - KHÔNG cần sửa
+}
+```
+
+### Bước 2: Thêm translation tiếng Việt
+
+**File:** `lang/vi/enums.php`
+
+```php
+return [
+    // ... existing keys ...
+    
+    'service' => [
+        'management_fee' => 'Phí quản lý',
+        'gratitude' => 'Tri ân',
+        'self_business' => 'Tự doanh',
+        'maintenance' => 'Bảo trì định kỳ',  // ← THÊM MỚI
+    ],
+    
+    // ... existing keys ...
+];
+```
+
+### Bước 3: Thêm translation tiếng Anh
+
+**File:** `lang/en/enums.php`
+
+```php
+return [
+    // ... existing keys ...
+    
+    'service' => [
+        'management_fee' => 'Management fee',
+        'gratitude' => 'Gratitude',
+        'self_business' => 'Self business',
+        'maintenance' => 'Periodic maintenance',  // ← THÊM MỚI
+    ],
+    
+    // ... existing keys ...
+];
+```
+
+### Bước 4: Reload browser
+
+Không cần chạy lệnh nào, chỉ cần reload trang.
+
+## Ví dụ: Thêm Contract Type mới
+
+### Bước 1: Thêm case
+
+**File:** `app/Enums/ContractType.php`
+
+```php
+enum ContractType: string
+{
+    case SALE = 'sale';
+    case LEASE = 'lease';
+    case BCC = 'bcc';
+    case CONSORTIUM = 'consortium';  // ← THÊM MỚI
+
+    public function label(): string
+    {
+        return match ($this) {
+            self::SALE => __('enums.contract_type.sale'),
+            self::LEASE => __('enums.contract_type.lease'),
+            self::BCC => __('enums.contract_type.bcc'),
+            self::CONSORTIUM => __('enums.contract_type.consortium'),  // ← THÊM MỚI
+        };
+    }
+
+    public function color(): string
+    {
+        return match ($this) {
+            self::SALE => 'success',
+            self::LEASE => 'info',
+            self::BCC => 'warning',
+            self::CONSORTIUM => 'primary',  // ← THÊM MỚI
+        };
+    }
+}
+```
+
+### Bước 2-3: Thêm translations
+
+```php
+// lang/vi/enums.php
+'contract_type' => [
+    'sale' => 'HĐ Mua bán',
+    'lease' => 'HĐ Thuê',
+    'bcc' => 'HĐ Hợp tác kinh doanh (BCC)',
+    'consortium' => 'HĐ Liên doanh',  // ← THÊM MỚI
+],
+
+// lang/en/enums.php
+'contract_type' => [
+    'sale' => 'Sale contract',
+    'lease' => 'Lease contract',
+    'bcc' => 'Business cooperation contract (BCC)',
+    'consortium' => 'Consortium contract',  // ← THÊM MỚI
+],
+```
+
+## Template Enum (Copy-paste)
+
+Khi tạo enum mới, copy template sau:
+
+```php
+<?php
+
+namespace App\Enums;
+
+/**
+ * [Tên] Enum
+ * 
+ * Để thêm giá trị mới:
+ * 1. Thêm case mới vào enum
+ * 2. Thêm label trong lang/vi/enums.php và lang/en/enums.php
+ * 3. Reload browser
+ */
+enum [EnumName]: string
+{
+    case [CASE_1] = '[value_1]';
+    case [CASE_2] = '[value_2]';
+
+    public function label(): string
+    {
+        return match ($this) {
+            self::[CASE_1] => __('enums.[enum_name].[value_1]'),
+            self::[CASE_2] => __('enums.[enum_name].[value_2]'),
+        };
+    }
+
+    public function color(): string
+    {
+        return match ($this) {
+            self::[CASE_1] => 'success',
+            self::[CASE_2] => 'info',
+        };
+    }
+
+    public static function options(): array
+    {
+        return collect(self::cases())->mapWithKeys(fn ($case) => [
+            $case->value => $case->label(),
+        ])->toArray();
+    }
+}
+```
+
+## Cách sử dụng Enum trong code
+
+### Trong Filament Form
+```php
+Select::make('service_type')
+    ->label(__('enums.service_type'))
+    ->options(ServiceType::options())
+    ->required(),
+```
+
+### Trong Filament Table
+```php
+TextColumn::make('service_type')
+    ->badge()
+    ->color(fn (string $state): string => ServiceType::from($state)->color())
+    ->formatStateUsing(fn (string $state): string => ServiceType::from($state)->label()),
+```
+
+### Trong PHP code
+```php
+$type = ServiceType::MANAGEMENT_FEE;
+echo $type->label();  // "Phí quản lý"
+echo $type->value;    // "management_fee"
+echo $type->color();  // "info"
+```
+
+## Lưu ý
+
+1. **`options()` method** - PHẢI là `static` (không phải instance method)
+2. **Translation keys** - Phải có trong CẢ `lang/vi/enums.php` VÀ `lang/en/enums.php`
+3. **Color values** - Sử dụng Filament colors: `primary`, `success`, `warning`, `danger`, `info`, `gray`
+4. **Case values** - Nên dùng snake_case (ví dụ: `management_fee`, không phải `ManagementFee`)

+# Hướng dẫn Đa ngôn ngữ (i18n)
+
+## Tổng quan
+
+Hệ thống hỗ trợ 2 ngôn ngữ:
+- **Tiếng Việt (vi)** - Ngôn ngữ chính
+- **Tiếng Anh (en)** - Ngôn ngữ dự phòng
+
+Cấu hình trong `.env`:
+```
+APP_LOCALE=vi
+APP_FALLBACK_LOCALE=en
+```
+
+## Cấu trúc thư mục
+
+```
+lang/
+├── en/
+│   ├── app.php          # UI chung: navigation, labels, status, widgets
+│   ├── feedback.php     # Domain feedback: services, notifications, interactions
+│   └── enums.php        # Labels cho enums
+└── vi/
+    ├── app.php
+    ├── feedback.php
+    └── enums.php
+```
+
+## Quy tắc đặt tên Translation Keys
+
+### 1. Resource Labels
+```php
+// Pattern: app.resource_{name}
+'resource_feedbacks' => 'Phản ánh',
+'resource_products' => 'Sản phẩm',
+'resource_customers' => 'Khách hàng',
+```
+
+### 2. Status Labels
+```php
+// Pattern: app.status_{name}
+'status_pending' => 'Chờ xử lý',
+'status_processing' => 'Đang xử lý',
+'status_resolved' => 'Đã xử lý',
+'status_closed' => 'Đã đóng',
+```
+
+### 3. Form Labels
+```php
+// Pattern: app.{field_name}
+'name' => 'Tên',
+'email' => 'Email',
+'phone' => 'Điện thoại',
+```
+
+### 4. Enum Labels
+```php
+// Pattern: enums.{enum_name}.{case_value}
+'service.management_fee' => 'Phí quản lý',
+'contract_status.active' => 'Đang hiệu lực',
+```
+
+### 5. Feedback Domain
+```php
+// Pattern: feedback.{action}_{context}
+'already_closed' => 'Phiếu này đã được đóng.',
+'close_permission_denied' => 'Chỉ lãnh đạo cấp phòng mới có quyền đóng phiếu.',
+```
+
+## Cách sử dụng trong code
+
+### Resource Labels
+```php
+// Phải override getPluralLabel() - KHÔNG tự dịch
+public static function getPluralLabel(): ?string
+{
+    return __('app.resource_feedbacks');
+}
+
+// Phải override getNavigationGroup() - KHÔNG tự dịch
+public static function getNavigationGroup(): ?string
+{
+    return __('app.nav_customer_care');
+}
+```
+
+### Form Fields
+```php
+// PHẢI thêm ->label() explicit
+TextInput::make('name')->label(__('app.name'))
+Select::make('status')->label(__('app.status'))
+```
+
+### RelationManager Title
+```php
+// Phải override getTitle() - KHÔNG dùng $title property
+public static function getTitle(Model $ownerRecord, string $pageClass): string
+{
+    return __('app.services');
+}
+```
+
+### Widget Heading/Description
+```php
+// Phải override getHeading()/getDescription() - KHÔNG dùng property
+public function getHeading(): string | Htmlable | null
+{
+    return __('app.widget_avg_time_by_handler');
+}
+```
+
+### Enum Labels
+```php
+public function label(): string
+{
+    return match ($this) {
+        self::ACTIVE => __('enums.contract_status.active'),
+    };
+}
+```
+
+## Cách thêm Translation Key mới
+
+### Bước 1: Thêm vào `lang/vi/app.php`
+```php
+return [
+    // ... existing keys ...
+    'new_key' => 'Giá trị tiếng Việt',
+];
+```
+
+### Bước 2: Thêm vào `lang/en/app.php`
+```php
+return [
+    // ... existing keys ...
+    'new_key' => 'English value',
+];
+```
+
+### Bước 3: Sử dụng trong code
+```php
+echo __('app.new_key');
+```
+
+## Lưu ý quan trọng
+
+1. **`$pluralLabel` property** - KHÔNG tự dịch, phải override `getPluralLabel()`
+2. **`getNavigationGroup()`** - KHÔNG tự dịch, phải gọi `__()`
+3. **`$heading`/`$description`** trong ChartWidget - KHÔNG tự dịch, phải override methods
+4. **Form fields** - PHẢI thêm `->label()` explicit
+5. **`$title`** trong RelationManager - KHÔNG tự dịch, phải override `getTitle()`
+6. **Filament vendor** - Có sẵn 57 file dịch tiếng Việt, tự kích hoạt khi `APP_LOCALE=vi`
+
+## Kiểm tra Translation
+
+```bash
+# Kiểm tra key có tồn tại không
+php artisan tinker --execute="echo __('app.new_key');"
+
+# Kiểm tra locale hiện tại
+php artisan tinker --execute="echo app()->getLocale();"
+```
