# 🎉 Request Detail Template System - Complete Implementation
|
|
|
|
## Executive Summary
|
|
|
|
I've successfully transformed your RequestDetail component into a **flexible, reusable, template-driven architecture** that supports multiple user types (dealers, vendors, standard users) with customizable views. This implementation follows .NET enterprise best practices and is production-ready.
|
|
|
|
## ✅ What Has Been Delivered
|
|
|
|
### 1. **Core Template System**

|
|
|
- ✅ **Template Types System** (`template.types.ts`)
|
|
- Full TypeScript type definitions
|
|
- Template configuration interfaces
|
|
- Context API for tab components
|
|
- Lifecycle hooks and access control
|
|
|
|
- ✅ **Template Registry & Selector** (`templates/index.ts`)
|
|
- Centralized template management
|
|
- Automatic template selection logic
|
|
- Runtime template registration support
|
|
|
|
### 2. **Three Built-in Templates**
|
|
|
|
#### **Standard Template** (Default)
|
|

|
|
|
|
✅ **Fetch IO Budget**
|
|

|
|
request.category === 'vendor' → Vendor Template
|
|
user.role === 'vendor' → Vendor Template
|
|
default → Standard Template
|
|

|
|
- Conditional tabs based on request state
|
|
- Badge notifications (e.g., unread messages)
|
|
- Custom tab components
|
|
- Configurable tab order
|
|
```
|
|
|
|
### 🔒 **Access Control**
|
|
|
|
```typescript
|
|
- Template-level access control
|
|
- Tab-level visibility control
|
|
- Role-based feature access
|
|
- Permission-based actions
|
|
```
|
|
|
|
### ⚡ **Custom Actions**
|
|
|
|
```typescript
|
|
- Template-specific quick actions
|
|
- Context-aware action visibility
|
|
- Custom action handlers
|

## 🚀 How to Use
|
|
|
|
### For Dealers (Claim Management)
|
|
|
|
```tsx
|
|
import { RequestDetailTemplated } from '@/pages/RequestDetail';
|
|
|
|
// Backend: Set category
|
|
{
|
|
requestId: "RE-REQ-2024-CM-100",
|
|
category: "claim-management", // ← Triggers Dealer Claim Template
|
|
claimAmount: 1000
|
|
}
|
|
|
|
// Frontend: Use component
|
|
<RequestDetailTemplated requestId="RE-REQ-2024-CM-100" />
|
|
|
|
// Result: Shows IO tab with SAP budget management
|
|
```
|
|
|
|
### For Standard Requests
|
|
|
|
```tsx
|
|
// Backend: Regular request
|
|
{
|
|
requestId: "REQ-2024-001",
|
|
category: "standard"
|
|
}
|
|
|
|
// Frontend: Same component
|
|
<RequestDetailTemplated requestId="REQ-2024-001" />
|
|
|
|
// Result: Shows standard tabs
|
|
```
|
|
|
|
### Create Custom Template
|
|
|
|
```tsx
|
|
// 1. Define template
|
|
export const myTemplate: RequestDetailTemplate = {
|
|
id: 'myCustom',
|
|
name: 'My Template',
|
|
tabs: [...],
|
|
// ... configuration
|
|
};
|
|
|
|
// 2. Register
|
|
import { registerTemplate } from '@/pages/RequestDetail/templates';
|
|
registerTemplate(myTemplate);
|
|
|
|
// 3. Use
|
|
<RequestDetailTemplated template="myCustom" requestId="REQ-123" />
|
|
```
|
