# ClaimReportCertificateView.vue Migration Documentation

**Migration Start**: 2025-07-08 11:25 UTC  
**Component**: ClaimReportCertificateView.vue  
**Priority**: High (Critical User Journey)  
**Location**: `src/views/ClaimReportCertificateView.vue`

## Pre-Migration Analysis

### 🔍 **Current State Assessment**

#### Database Operations
- **Legacy Pattern**: Uses `databaseUtil.retrieveSettingsForActiveAccount()`
- **Raw SQL**: Uses `platformService.dbQuery("SELECT * FROM contacts")`
- **Data Mapping**: Uses `databaseUtil.mapQueryResultToValues()`
- **PlatformServiceFactory**: Direct usage instead of mixin

#### Notification Usage
- **Direct $notify Calls**: 1 instance found
- **Notification Type**: danger (error handling)
- **Message**: Error loading claim

#### Template Complexity
- **Simple Template**: Minimal template with canvas element
- **Canvas Rendering**: Complex canvas drawing logic in component
- **QR Code Generation**: Uses QRCode library for certificate generation

### 📋 **Migration Requirements**

#### 1. Database Migration
- [ ] Replace `databaseUtil.retrieveSettingsForActiveAccount()` with PlatformServiceMixin
- [ ] Replace raw SQL query with service method
- [ ] Replace `databaseUtil.mapQueryResultToValues()` with proper typing
- [ ] Replace PlatformServiceFactory with PlatformServiceMixin

#### 2. SQL Abstraction
- [ ] Replace `platformService.dbQuery("SELECT * FROM contacts")` with `$getAllContacts()`
- [ ] Use proper service methods for all database operations

#### 3. Notification Migration
- [ ] Extract notification message to constants
- [ ] Replace direct `$notify()` call with helper method

#### 4. Template Streamlining
- [ ] Extract canvas drawing logic to computed properties where possible
- [ ] Simplify component methods

## Migration Plan

### 🎯 **Step 1: Database Migration**
Replace legacy database operations with PlatformServiceMixin methods:

```typescript
// Before
const settings = await databaseUtil.retrieveSettingsForActiveAccount();
const platformService = PlatformServiceFactory.getInstance();
const dbAllContacts = await platformService.dbQuery("SELECT * FROM contacts");
const allContacts = databaseUtil.mapQueryResultToValues(dbAllContacts);

// After
const settings = await this.$settings();
this.allContacts = await this.$getAllContacts();
```

### 🎯 **Step 2: Notification Migration**
Extract notification message and use helper method:

```typescript
// Before
this.$notify({
  group: "alert",
  type: "danger",
  title: "Error",
  text: "There was a problem loading the claim.",
});

// After
this.notify.error(NOTIFY_ERROR_LOADING_CLAIM.message, TIMEOUTS.LONG);
```

### 🎯 **Step 3: Template Optimization**
Extract canvas constants and simplify methods:

```typescript
// Add computed properties for canvas dimensions
get CANVAS_WIDTH() {
  return 1100;
}

get CANVAS_HEIGHT() {
  return 850;
}
```
