## 🗄️ Database Schema
|
||||
|

|
||||

|
||||
|
||||
## 🏗️ Architecture Pattern
|
||||
|
||||
### Module Structure
|
||||
|
||||
```
|
||||
src/modules/{module-name}/
|
||||
├── model.ts - Elysia type definitions
|
||||
├── service.ts - Business logic & database operations
|
||||
├── controller.ts - API route handlers
|
||||
└── index.ts - Module exports
|
||||
```
|
||||
|
||||
### Design Principles
|
||||
|
||||
- **Separation of Concerns:** แยก model, service, controller ชัดเจน
|
||||
- **Branch Scoping:** ทุก query ถูก filter โดย `branchId`
|
||||
- **Soft Delete:** ใช้ `deletedAt` แทนการลดจริง
|
||||
- **Multi-tenant Ready:** เตรียมพร้อมสำหรับ RBAC/ABAC
|
||||
- **Type Safety:** ใช้ TypeScript + Elysia types
|
||||
|
||||

|
||||
|
||||
## 🔐 Security & Access Control
|
||||
|
||||
### Branch Middleware
|
||||
|
||||
ทุก module ใช้ `branchMiddleware` ที่ inject:
|
||||
|
||||
- `currentBranchId` - Branch ปัจจุบัน
|
||||
- `userId` - User ID
|
||||
- `userGroups` - User groups/roles
|
||||
- `accessibleBranches` - Branches ที่มีสิทธิ์เข้าถึง
|
||||
|
||||
### Permission Checks
|
||||
|
||||
- **Standard Modules:** ต้องมี branch access
|
||||
- **Audit Logs:** Admin/Superadmin/Auditor only
|
||||

|

|
||||
## 📊 API Response Format
|
||||
|
||||
### Success Response
|
||||
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"data": { ... },
|
||||
"count": 10,
|
||||
"message": "Success message"
|
||||
}
|
||||
```
|
||||
|
||||
### Error Response
|
||||
|
||||
```json
|
||||
{
|
||||
"success": false,
|
||||
"error": "Error message",
|
||||
"details": "Detailed error info"
|
||||
}
|
||||
```
|
||||

||||
### 2. Create Location
|
||||

|
||||
"type": "province",
|
||||
"parentId": "country-th-id"
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Search Industrial Estates
|
||||
|
||||
```bash
|
||||
GET /api/industrial-estates?locationId=th-10&isActive=true&search=บางพลี
|
||||
```
|
||||
|
||||
### 4. Get Audit Logs (Admin only)
|
||||
|
||||
```bash
|
||||
GET /api/audit-logs?startDate=2026-01-01&endDate=2026-12-31&limit=100
|
||||
```

|
||||
- Revision system
|
||||
- Multi-currency support
|
||||
- Contact visibility validation
|
||||
|
||||
### Phase 4: ERP Integration
|
||||
|
||||

## 📝 Notes
|
||||
|
||||
### Current Status
|
||||
|
||||
- ✅ All core infrastructure modules completed
|
||||
- ✅ Database schema updated
|
||||
- ✅ Branch scoping implemented
|
||||
- ✅ Audit logging ready
|
||||
- ⚠️ Middleware needs proper user authentication integration
|
||||
- ⚠️ Some TypeScript errors remain (middleware typing issues)
|
||||
|
||||
### Known Issues
|
||||
|
||||
1. **Middleware Typing:** `currentBranchId`, `userId`, `userGroups` ยังไม่ถูก inject อย่างถูกต้อง
|
||||
2. **Authentication:** ต้องเชื่อมต่อกับ Keycloak หรือ auth system
|
||||
3. **Migration:** ต้องสร้าง migration script สำหรับ production
|
||||
|
||||
### Next Steps
|
||||
|
||||
1. Fix middleware typing issues
|
||||
2. Integrate with authentication system
|
||||
3. Create database migration script
|
||||
4. Add comprehensive tests
|
||||
5. Implement Customer & Quotation modules
|
||||
6. Add ERP integration layer
