# DIDView.vue Database Migration Documentation

## Overview
DIDView.vue migration from mixed pattern to technically compliant by replacing legacy `databaseUtil` calls with PlatformServiceMixin methods.

## Migration Details

### File Information
- **File**: `src/views/DIDView.vue`
- **Size**: 940 lines
- **Migration Type**: Database utility migration
- **Complexity**: Low (only 2 calls to replace)

### Issues Found
1. `import * as databaseUtil from "../db/databaseUtil";` (line 268)
2. `databaseUtil.retrieveSettingsForActiveAccount()` (line 357)
3. `databaseUtil.mapQueryResultToValues()` (line 408)

### Changes Made

#### 1. Removed Legacy Import
```typescript
// ❌ BEFORE
import * as databaseUtil from "../db/databaseUtil";

// ✅ AFTER
// (removed - no longer needed)
```

#### 2. Replaced retrieveSettingsForActiveAccount()
```typescript
// ❌ BEFORE
private async initializeSettings() {
  const settings = await databaseUtil.retrieveSettingsForActiveAccount();
  this.activeDid = settings.activeDid || "";
  this.apiServer = settings.apiServer || "";
}

// ✅ AFTER
private async initializeSettings() {
  const settings = await this.$accountSettings();
  this.activeDid = settings.activeDid || "";
  this.apiServer = settings.apiServer || "";
}
```

#### 3. Replaced mapQueryResultToValues()
```typescript
// ❌ BEFORE
const dbContacts = await this.$dbQuery(
  "SELECT * FROM contacts WHERE did = ?",
  [this.viewingDid],
);
const contacts = databaseUtil.mapQueryResultToValues(
  dbContacts,
) as unknown as Contact[];

// ✅ AFTER
const dbContacts = await this.$dbQuery(
  "SELECT * FROM contacts WHERE did = ?",
  [this.viewingDid],
);
const contacts = this.$mapQueryResultToValues(
  dbContacts,
) as unknown as Contact[];
```

## Pre-Migration Status
- **Status**: Mixed Pattern File
- **Issues**: 2 legacy databaseUtil calls + 1 import
- **PlatformServiceMixin**: Already imported and configured

## Post-Migration Status
- **Status**: ✅ Technically Compliant
- **Issues**: 0 (all legacy patterns removed)
- **Validation**: Passes migration validation script
- **Linting**: No new errors introduced

## Validation Results

### Before Migration
```
Mixed pattern files: 3
- HomeView.vue
- DIDView.vue  ← Target file
- ContactsView.vue
```

### After Migration
```
Mixed pattern files: 1
- ContactsView.vue

Technically compliant files: 17
- DIDView.vue  ← Successfully migrated
- (16 others)
```

## Testing Requirements
DIDView.vue is now ready for human testing:
1. Test DID viewing functionality
2. Verify contact information display
3. Check visibility controls
4. Test registration functionality
5. Verify claims loading
6. Test contact deletion

## Next Steps
1. **Human testing**: DIDView.vue is ready for user testing
2. **Final migration**: Only ContactsView.vue remains (7 logConsoleAndDb calls)
3. **100% compliance**: Within reach after ContactsView.vue migration

## Migration Pattern Used
This migration followed the established pattern:
1. **Verify PlatformServiceMixin** is already imported and configured
2. **Remove legacy import** (`import * as databaseUtil`)
3. **Replace method calls** with mixin equivalents
4. **Validate changes** using migration validation script
5. **Check linting** to ensure no new errors
