# OfferDetailsView.vue Migration Documentation

**Date**: 2025-07-08  
**Component**: `src/views/OfferDetailsView.vue`  
**Migration Type**: Enhanced Triple Migration Pattern  
**Priority**: High (Week 2 Target)  
**Estimated Time**: 15-20 minutes  

## 📋 Pre-Migration Analysis

### 🔍 **Current State Assessment**

#### **Legacy Patterns Identified**
1. **Database Operations**: 
   - `databaseUtil.retrieveSettingsForActiveAccount()` (line 401)
   - Direct `PlatformServiceFactory.getInstance()` usage (line 415)
   - Raw SQL query: `"SELECT * FROM contacts"` (line 416)

2. **Notification System**:
   - 12 direct `$notify()` calls throughout the component
   - Inline notification messages
   - No centralized constants usage

3. **Template Complexity**:
   - Complex conditional logic in template
   - Multiple computed properties needed for template streamlining

### 📊 **Migration Complexity Assessment**
- **Database Migration**: Medium (2 database operations)
- **SQL Abstraction**: Low (1 raw SQL query)
- **Notification Migration**: High (12 notifications)
- **Template Streamlining**: Medium (complex conditionals)

### 🎯 **Migration Goals**
1. Replace `databaseUtil` calls with PlatformServiceMixin methods
2. Abstract raw SQL with service methods
3. Extract all notification messages to constants
4. Replace `$notify()` calls with helper methods
5. Streamline template with computed properties

## 🛠️ Migration Plan

### **Phase 1: Database Migration**
```typescript
// Replace databaseUtil.retrieveSettingsForActiveAccount()
const settings = await this.$getSettingsForActiveAccount();

// Replace PlatformServiceFactory.getInstance() + raw SQL
const allContacts = await this.$getAllContacts();
```

### **Phase 2: Notification Migration**
```typescript
// Extract to constants
NOTIFY_OFFER_ERROR_LOADING
NOTIFY_OFFER_ERROR_PREVIOUS_RECORD
NOTIFY_OFFER_ERROR_NO_IDENTIFIER
NOTIFY_OFFER_ERROR_NEGATIVE_AMOUNT
NOTIFY_OFFER_ERROR_NO_DESCRIPTION
NOTIFY_OFFER_PROCESSING
NOTIFY_OFFER_ERROR_PROJECT_ASSIGNMENT
NOTIFY_OFFER_ERROR_RECIPIENT_ASSIGNMENT
NOTIFY_OFFER_ERROR_CREATION
NOTIFY_OFFER_SUCCESS_RECORDED
NOTIFY_OFFER_ERROR_RECORDATION
NOTIFY_OFFER_PRIVACY_INFO

// Replace $notify calls with helper methods
this.notify.error(NOTIFY_OFFER_ERROR_LOADING.message, TIMEOUTS.LONG);
this.notify.success(NOTIFY_OFFER_SUCCESS_RECORDED.message, TIMEOUTS.STANDARD);
```

### **Phase 3: Template Streamlining**
```typescript
// Add computed properties
get recipientDisplayName() {
  return this.offeredToProject 
    ? this.projectName 
    : this.offeredToRecipient 
      ? this.recipientName 
      : "someone not named";
}

get projectAssignmentLabel() {
  return this.projectId 
    ? `This is offered to ${this.projectName}` 
    : "No project was chosen";
}

get recipientAssignmentLabel() {
  return this.recipientDid 
    ? `This is offered to ${this.recipientName}` 
    : "No recipient was chosen.";
}
```

## 🧪 Testing Requirements

### **Human Testing Checklist**
- [ ] **Offer Creation Flow**
  - [ ] Create new offer with description and amount
  - [ ] Set conditions and expiration date
  - [ ] Assign to project or recipient
  - [ ] Submit offer successfully
- [ ] **Offer Editing Flow**
  - [ ] Load existing offer for editing
  - [ ] Modify offer details
  - [ ] Submit edited offer
- [ ] **Validation Testing**
  - [ ] Test negative amount validation
  - [ ] Test missing description validation
  - [ ] Test missing identifier validation
- [ ] **Error Handling**
  - [ ] Test network error scenarios
  - [ ] Test server error responses
  - [ ] Test validation error messages
- [ ] **Notification Testing**

## 🔧 Implementation Notes

### **Key Migration Patterns**
1. **Database Operations**: Use `this.$getSettingsForActiveAccount()` and `this.$getAllContacts()`
2. **Notification Helpers**: Initialize `notify` helper in `created()` lifecycle
3. **Constants Usage**: Import from `@/constants/notifications`
4. **Template Optimization**: Extract complex logic to computed properties

### **Potential Challenges**
1. **Complex Offer Logic**: Multiple assignment scenarios (project vs recipient)
2. **Error Handling**: Various error conditions with different messages
3. **Template Complexity**: Multiple conditional displays
4. **State Management**: Complex form state with multiple dependencies

### **Success Criteria**
- [ ] All database operations use PlatformServiceMixin
- [ ] All notifications use centralized constants
- [ ] Template logic simplified with computed properties
- [ ] No linting errors
- [ ] Human testing validates all functionality
- [ ] Migration validation script passes
