User Model Migration - Implementation Summary

Completed Tasks ✅

1. Backend - New User Model

Files Created:

• BaldrTs/src/models/user.model.ts - MongoDB schema for unified User model
• BaldrTs/src/interfaces/user.interface.ts - TypeScript interface for User
• BaldrTs/src/controllers/user.controller.ts - CRUD operations for users
• BaldrTs/src/routes/user.route.ts - API routes for user management

Features:

• Email unique index
• Optional password (hashed with bcrypt)
• Optional firstName/lastName
• Last login tracking
• Full CRUD operations

2. Backend - Updated Protection Users

Files Modified:

• BaldrTs/src/models/protectionUser.model.ts - Now references User via user_id
• BaldrTs/src/interfaces/protectionUser.interface.ts - Updated interface with user_id
• BaldrTs/src/controllers/protectionUser.controller.ts - Updated to create/manage User records
• BaldrTs/src/middlewares/protection.middleware.ts - Updated to populate User data

Changes:

• Removed: email, password fields
• Added: user_id reference to User model
• Login now updates last_login in User model
• All operations populate user data

3. Backend - Updated Newsletter Subscribers

Files Modified:

• BaldrTs/src/models/newsletterSubscribers.model.ts - Now references User via user_id
• BaldrTs/src/interfaces/newsletterSubscribers.interface.ts - Updated interface with user_id
• BaldrTs/src/controllers/newsletterSubscribers.controller.ts - Auto creates/finds Users
• BaldrTs/src/services/crons/newsletter.cron.ts - Populates user data for emails

Changes:

• Removed: email, firstName, lastName fields
• Added: user_id reference to User model
• Create operation finds or creates User
• Unsubscribe looks up User by email

4. Backend - Migration Script

Files Created:

• BaldrTs/src/scripts/migrateToUserModel.ts - Automated migration script
• BaldrTs/documents/USER_MODEL_MIGRATION.md - Complete migration guide

Features:

• Migrates existing ProtectionUser data to User model
• Migrates existing NewsletterSubscriber data to User model
• Merges duplicate emails
• Updates all references
• Comprehensive error handling and logging
• Run with: npm run migrate:users

5. Backend - Router Updates

Files Modified:

• BaldrTs/src/routes/router.ts - Added user routes
• BaldrTs/package.json - Added migration script command

6. Frontend - Updated Interfaces

Files Created:

• Baldr-Bo/app/interfaces/baseUser.interface.ts - Base user interface

Files Modified:

• Baldr-Bo/app/interfaces/user.interface.ts - Now IProtectionUser with user_id
• Baldr-Bo/app/interfaces/newsletterSubscribers.interface.ts - Updated with user_id

API Endpoints

New User Endpoints

POST   /user              - Get all users (paginated)
POST   /user/search       - Search users by email/name
GET    /user/:id          - Get user by ID
GET    /user/email/:email - Get user by email
POST   /user/new          - Create new user
PUT    /user/edit/:id     - Update user (requires auth)
DELETE /user/delete       - Delete users (requires auth)
PUT    /user/last-login/:id - Update last login timestamp

Modified Endpoints

All existing endpoints continue to work but now return populated user data:

• /protection/user/* - Now includes populated user_id data
• /newsletter/subscribers/* - Now includes populated user_id data

Database Schema Changes

New Collection: users

{
  _id: ObjectId,
  email: String (unique),
  firstName: String (optional),
  lastName: String (optional),
  password: String (optional, hashed),
  last_login: Date (optional),
  createdAt: Date,
  updatedAt: Date
}

Updated Collection: protectionusers

{
  _id: ObjectId,
  user_id: ObjectId (ref: 'User'), // NEW
  userName: String (unique),
  slug: String,
  groups: [ObjectId],
  module_id: ObjectId (optional),
  active: Boolean,
  // REMOVED: email, password
}

Updated Collection: newslettersubscribers

{
  _id: ObjectId,
  user_id: ObjectId (ref: 'User'), // NEW
  groups: [ObjectId],
  active: Boolean,
  // REMOVED: email, firstName, lastName
}

Migration Workflow

1. Backup Database

   mongodump --uri="mongodb://..." --out=backup

2. Deploy Backend Updates

   cd BaldrTs
   npm install
   npm run build

3. Run Migration

   npm run migrate:users

4. Verify Results

   • Check Users collection created
   • Check user_id fields populated
   • Test API endpoints

5. Update Frontend

   • Update API calls to handle populated user data
   • Update UI to display user information correctly

Key Benefits

✅ Single Source of Truth - User data in one place ✅ No Data Duplication - Email/names stored once ✅ Better Data Integrity - Enforced relationships ✅ Easier Maintenance - Update user info in one place ✅ Password Security - Consistent hashing, optional passwords ✅ Login Tracking - Last login timestamp for all users ✅ Future-Proof - Easy to add new user-related features

Testing Checklist

• Run migration script on test database
• Verify User records created correctly
• Test protection user login
• Test newsletter subscriber creation
• Test newsletter subscriber unsubscribe
• Test newsletter email sending (cron)
• Test user search functionality
• Test user update operations
• Verify frontend displays populated user data
• Check all TypeScript compilation passes
• Run backend tests
• Test rollback procedure

Notes

• Migration is idempotent - can be run multiple times safely
• Existing functionality is backward compatible during transition
• Password remains optional in User model (for newsletter-only users)
• Email is unique across all users
• Frontend interfaces use type-only imports for proper module syntax
