Health Petal Database

This project contains the database schema, seed data, and related tools for the Health Petal application.

Setup

1. Make sure PostgreSQL is installed and running on your machine
2. Create a database named health_petal
3. Configure your .env file with the correct database credentials (or use the default ones)

Database Schema

The database schema includes the following tables:

• profiles (users)
• role_info
• user_roles
• hospital
• specializations
• hospital_specializations
• hospital_employees
• doctor_info
• doctor_specializations
• doctor_secretaries
• doctor_availability
• token_info
• running_counter

Available Commands

• npm run migrate - Generate SQL migration files
• npm run db:push - Push schema changes to the database
• npm run db:seed - Seed the database with mock data
• npm run docker:build - Build Docker image for the backend

Getting Started

1. First, install dependencies:

   npm install
   

2. Set up the database:

   # Create a PostgreSQL database
   createdb health_petal
   
   # Generate and push the schema
   npm run migrate
   npm run db:push
   
   # Seed the database with test data
   npm run db:seed
   

3. Verify the data:

   -- Connect to the database
   psql health_petal
   
   -- Check the tables
   \dt
   
   -- Check users
   SELECT * FROM profiles;
   
   -- Check doctors
   SELECT p.name, p.email, d.qualifications, d.daily_token_count
   FROM doctor_info d
   JOIN profiles p ON d.user_id = p.id;
   
   -- Check doctor specializations
   SELECT p.name, s.name as specialization
   FROM doctor_specializations ds
   JOIN doctor_info d ON ds.doctor_id = d.id
   JOIN profiles p ON d.user_id = p.id
   JOIN specializations s ON ds.specialization_id = s.id;
   

Docker

This project includes Docker support for easy deployment:

1. Build the Docker image:

   npm run docker:build
   

2. Run with Docker Compose (includes PostgreSQL database):

   docker-compose up -d
   

The Docker Compose setup includes:

• PostgreSQL database with the correct schema
• Backend application with all environment variables configured

Note: For production deployment, make sure to update the environment variables in docker-compose.yml with your actual values.
