cd smart-attendence

2. Create Virtual Environment

# Create virtual environment
python -m venv attendance_env

# Activate virtual environment
# On Windows:
attendance_env\Scripts\activate

# On macOS/Linux:
source attendance_env/bin/activate

3. Install Dependencies

# Install required packages
pip install -r requirements.txt

# If requirements.txt doesn't exist, install manually:
pip install flask flask-sqlalchemy flask-migrate pandas openpyxl weasyprint

4. Environment Configuration

# Create .env file
touch .env

# Add the following variables to .env:
FLASK_APP=app.py
FLASK_ENV=development
SECRET_KEY=your-secret-key-here
DATABASE_URL=sqlite:///attendance.db

5. Database Setup

# Initialize database
flask db init
flask db migrate -m "Initial migration"
flask db upgrade

6. Run the Application

# Start the development server
flask run

# Or alternatively:
python app.py

The application will be available at http://localhost:5000

🚀 Deployment

Render Deployment (Recommended)

1. Prepare for Deployment:

   # Ensure you have these files:
   # - requirements.txt
   # - Procfile (web: gunicorn app:app)
   # - runtime.txt (python-3.9.x)

2. Database Configuration:

   • Set DATABASE_URL environment variable to PostgreSQL URL
   • Update database configurations for production

3. Deploy on Render:

   • Connect your GitHub repository
   • Configure build and start commands
   • Set environment variables
   • Deploy automatically from main branch
