Features

• User Authentication: Separate login forms for users and admins.
• Quiz Management: Admins can add quiz questions.
• Dynamic Quiz Taking: Users can take quizzes and get immediate feedback.

Project Structure

• appy.py: Flask application files.
• env/: Virtual environment directory.
• static/: Contains static files like CSS.
  • src/input.css: TailwindCSS entry point.
• templates/: HTML templates for the application.
  • admin.html: Admin interface for managing quizzes.
  • index.html: Landing page with login forms.
  • quiz.html: Quiz taking interface for users.
  • result.html: Displays quiz results to users.
• tailwind.config.js: TailwindCSS configuration.
• connect.py: Credentials to establish connection with Database.
• package.json: Node.js project file with dependencies.
• requirements.txt: Python dependencies.
• interview_questions_mcq.xlsx: Excel file containing quiz questions.

Setup

1. Clone the repository

git clone https://github.com/ifsvivek/DBMS-Project

2. Install dependencies

Ensure you have Node.js installed, then run:

npm install

3. Generate TailwindCSS

npx tailwindcss -i ./static/src/input.css -o ./static/dist/css/output.css --watch

4. Activate the virtual environment

python -m venv env  # Create a virtual environment

env\Scripts\activate  # On Windows
source env/bin/activate  # On Unix or MacOS

5. Install Python dependencies

pip install -r requirements.txt

6. Change the Database Credentials

host="localhost"
user="<Your_Username>" # root is default user
password="<Your_Password>"
database="<Your_Database_Name>"

Implementing Password and proper log in method

Use bcrypt to hash the password before saving it to the database.

• Function to Hash the Password and Save it to the user Table

import bcrypt
import mysql.connector

def hash_and_save_password(username, password, connection):
    # Hash the password
    salt = bcrypt.gensalt()
    hashed_password = bcrypt.hashpw(password.encode('utf-8'), salt)

    # Save the username and hashed password to the user table
    cursor = connection.cursor()
    sql_query = "INSERT INTO user (username, password) VALUES (%s, %s)"
    cursor.execute(sql_query, (username, hashed_password.decode('utf-8')))
    connection.commit()
    cursor.close()

• Function to Verify the Password

def verify_password(username, entered_password, connection):
    # Retrieve the hashed password from the database
    cursor = connection.cursor()
    sql_query = "SELECT password FROM user WHERE username = %s"
    cursor.execute(sql_query, (username,))
    result = cursor.fetchone()
    cursor.close()

    if result is None:
        return False

    stored_hashed_password = result[0].encode('utf-8')

    # Verify the entered password against the stored hashed password
    return bcrypt.checkpw(entered_password.encode('utf-8'), stored_hashed_password)
