This project is a 3-tier web application built using Python for the backend, with PostgreSQL as the database. The application consists of a presentation layer, a business logic layer, and a data access layer.

• Prerequisites
• Installation
  • 1. Setting Up Python Virtual Environment
  • 2. Installing PostgreSQL
  • 3. Setting Up PostgreSQL Database
• Running the Application
• License

Before setting up the project, ensure you have the following installed on your machine:

• Ubuntu (or another compatible Linux distribution)
• Python 3.12 or higher
• PostgreSQL

1. Install the Python 3.12 virtual environment package:

   sudo apt install python3.12-venv -y

2. Create a virtual environment:

   python3 -m venv myenv

3. Activate the virtual environment:

   source myenv/bin/activate

4. Install required Python libraries from requirements.txt:

   First, ensure pip is installed:

   sudo apt install python3-pip -y

   Then, install the required libraries:

   pip3 install -r requirements.txt

To install and set up PostgreSQL, follow these steps:

1. Install PostgreSQL and additional tools:

   sudo apt-get install postgresql postgresql-contrib

2. Start the PostgreSQL service:

   sudo systemctl start postgresql

3. Enable PostgreSQL to start on boot:

   sudo systemctl enable postgresql

1. Switch to the PostgreSQL user:

   sudo -i -u postgres

2. Create a new PostgreSQL user:

   CREATE USER root WITH PASSWORD 'root';

3. Create a new PostgreSQL database:

   CREATE DATABASE my_database;

4. Grant all privileges on the database to the new user:

   GRANT ALL PRIVILEGES ON DATABASE my_database TO root;

5. Connect to the new database:

   \c my_database

6. Grant all privileges on the public schema to the user:

   GRANT ALL PRIVILEGES ON SCHEMA public TO root;

7. Grant create privileges on the database to the user:

   GRANT CREATE ON DATABASE my_database TO root;

Once the environment and database are set up, you can run the application with the following steps:

1. Ensure your virtual environment is activated:

   source myenv/bin/activate

2. Run the application:

   python run.py

   The application will start, and you can access it via the specified host and port in your configuration.
