Staff User Account Feature - Implementation Summary

Executive Summary

The Staff User Account feature is FULLY IMPLEMENTED and production-ready. The optional one-to-one relationship between Staff and User models exists, complete CRUD operations are available, and staff login functionality is fully functional.

What's Already Implemented

✅ 1. Optional One-to-One Relationship with User Model

Location: apps/organizations/models.py (Line 112-117)

# Link to User (Keep it optional for external/temp staff)
user = models.OneToOneField(
    'accounts.User',
    on_delete=models.SET_NULL,
    null=True, blank=True,
    related_name='staff_profile'
)

Key Features:

  • Optional: Staff can exist without a user account
  • SET_NULL: Preserves staff record if user is deleted
  • Reverse lookup: user.staff_profile for easy access

✅ 2. Complete CRUD Operations

A. Django Admin Interface

Location: apps/organizations/admin.py

Features:

  • Full CRUD for Staff model
  • Custom column: has_user_account (✓ Yes / ✗ No with color coding)
  • Bulk actions:
    • "Create user accounts for selected staff"
    • "Send credential emails to selected staff"
  • Filtering by status, hospital, staff type, specialization
  • Search by name, Arabic names, employee ID, license, job title
  • Autocomplete for hospital, department, and user fields

B. REST API Endpoints

Location: apps/organizations/views.py (StaffViewSet)

Standard CRUD:

GET    /api/organizations/staff/              - List staff
POST   /api/organizations/staff/              - Create staff
GET    /api/organizations/staff/{id}/         - Get staff details
PUT    /api/organizations/staff/{id}/         - Update staff
PATCH  /api/organizations/staff/{id}/         - Partial update
DELETE /api/organizations/staff/{id}/         - Delete staff

Custom User Management Actions:

POST /api/organizations/staff/{id}/create_user_account/  - Create user account
POST /api/organizations/staff/{id}/link_user/            - Link existing user
POST /api/organizations/staff/{id}/unlink_user/          - Unlink user
POST /api/organizations/staff/{id}/send_invitation/      - Resend credentials

C. Web Interface (UI Views)

Location: apps/organizations/ui_views.py

Pages:

  • staff_list - Paginated list with filters and search
  • staff_detail - Detailed view with user account management
  • staff_create - Create new staff with optional user account
  • staff_update - Edit staff with optional user account creation

Features:

  • Role-based filtering (PX Admin sees all, Hospital Admin sees their hospital)
  • Search by name, employee ID, license, specialization, job title
  • Filters by hospital, department, status, staff type
  • Inline user account management in detail view

✅ 3. Staff Login Functionality

User Account Creation

Location: apps/organizations/services.py (StaffService)

Method: create_user_for_staff(staff, role='staff', request=None)

Process:

  1. Validates staff doesn't already have a user account
  2. Requires staff to have an email address
  3. Generates unique username (format: firstname.lastname)
  4. Generates secure 12-character random password
  5. Creates User with:
    • Email as primary identifier
    • Username (for backward compatibility)
    • First/last name
    • Employee ID
    • Hospital and Department
    • Active status
  6. Assigns role via group membership
  7. Links user to staff
  8. Logs audit trail
  9. Sends credentials email

Username Generation:

# Examples:
John Smith → john.smith
Duplicate → john.smith2
Another duplicate → john.smith3

Password Generation:

# Cryptographically secure 12-character password
# Characters: A-Z, a-z, 0-9, punctuation
# Example: Xk9#mP2$vL5!

Login Process

Staff can login using:

  1. Email (primary identifier)
  2. Password (received via email)
  3. Login URL: /accounts/login/

After First Login:

  • Staff should change their password for security
  • Password change available at user settings

✅ 4. Staff Service (Business Logic)

Location: apps/organizations/services.py

Available Methods:

Method Description
create_user_for_staff() Creates user account for staff
link_user_to_staff() Links existing user to staff
unlink_user_from_staff() Removes user association
send_credentials_email() Sends login credentials via email
generate_username() Generates unique username from name

Troubleshooting

Common Issues

Issue Cause Solution
"Staff member already has a user account" Duplicate creation attempt Check staff.user before creating
"Staff member must have an email address" Creating user without email Add email to staff profile first
Email not sent Email configuration issue Check EMAIL_* settings, verify SMTP credentials
"Username already exists" Non-unique username Service handles this automatically
Permission denied User lacks required role Ensure user is PX Admin or Hospital Admin
Login fails Incorrect credentials Verify email/password, check user.is_active
