Doctor Portal - Quick Fix Guide

Error: "no such column: users.doctor_id"

This error occurs because the database schema needs to be updated to include the new doctor_id column.

Quick Fix (Run This)

python fix_database_for_doctor_portal.py

This script will:

  1. ✅ Add doctor_id column to users table
  2. ✅ Create a test doctor user account
  3. ✅ Link the user to a doctor profile
  4. ✅ Display all login credentials

Manual Fix (If Script Fails)

Option 1: Update Existing Database

python migrate_add_doctor_column.py
python create_doctor_user.py

Option 2: Fresh Start (Recommended)

# 1. Stop the application (Ctrl+C)

# 2. Delete the old database
rm instance/hospital.db    # Linux/Mac
del instance\hospital.db   # Windows

# 3. Recreate database with sample data
python seed_data.py

# 4. Run the fix script
python fix_database_for_doctor_portal.py

# 5. Start the application
python run.py

Verify It's Working

  1. Start the application:

    python run.py

  2. Open browser:

    http://localhost:5000/auth/login

  3. Login as doctor:

    Email:    doctor@hospital.com

    • Doctor Dashboard with statistics
    • Navigation menu with doctor options
    • Today's appointments and queue
