from flask import Flask, render_template, request import mysql.connector

app = Flask(name)

Connect to the MySQL database

mydb = mysql.connector.connect( host="localhost", user="yourusername", password="yourpassword", database="yourdatabase" )

Define the route for the home page

@app.route('/') def home(): return render_template('index.html')

Define the route for the create operation

@app.route('/create', methods=['GET', 'POST']) def create(): if request.method == 'POST': name = request.form['name'] email = request.form['email'] cursor = mydb.cursor() sql = "INSERT INTO users (name, email) VALUES (%s, %s)" val = (name, email) cursor.execute(sql, val) mydb.commit() return 'User created successfully!' else: return render_template('create.html')

Define the route for the read operation

@app.route('/read') def read(): cursor = mydb.cursor() cursor.execute("SELECT * FROM users") result = cursor.fetchall() return render_template('read.html', result=result)

Define the route for the update operation

@app.route('/update', methods=['GET', 'POST']) def update(): if request.method == 'POST': id = request.form['id'] name = request.form['name'] email = request.form['email'] cursor = mydb.cursor() sql = "UPDATE users SET name=%s, email=%s WHERE id=%s" val = (name, email, id) cursor.execute(sql, val) mydb.commit() return 'User updated successfully!' else: return render_template('update.html')

Define the route for the delete operation

@app.route('/delete', methods=['GET', 'POST']) def delete(): if request.method == 'POST': id = request.form['id'] cursor = mydb.cursor() sql = "DELETE FROM users WHERE id=%s" val = (id,) cursor.execute(sql, val) mydb.commit() return 'User deleted successfully!' else: return render_template('delete.html')

if name == 'main': app.run(debug=True)
