Digital Library Application

A simple web application for managing a digital library, built with Flask and SQLAlchemy. This application allows users to add authors and books, search for books or authors, and view detailed information about them.

Features

• Search for books by title or author.
• View detailed information about each book and author.
• Add new authors and books to the library.
• Delete books (and their authors if no other books exist for that author).

Requirements

• Python 3.6 or higher
• Flask
• Flask-SQLAlchemy

Installation

1. Clone this repository:

   git clone https://github.com/yourusername/digital-library.git
   cd digital-library
   
    Create a virtual environment and activate it:
   
    bash
   

python -m venv venv source venv/bin/activate # On Windows use venv\Scripts\activate

Install the required packages:

bash

pip install Flask Flask-SQLAlchemy

Set the SECRET_KEY environment variable for security (optional but recommended):

bash

export SECRET_KEY='your_secret_key' # On Windows use set SECRET_KEY='your_secret_key'

Initialize the database (if not already created). This is handled in the code, but you can manually create the database if necessary:

bash

flask shell
from models import db
db.create_all()
exit()

Running the Application

To run the application, use the following command:

bash

python app.py

You can then access the application at http://127.0.0.1:5000/ in your web browser. Usage
