Install necessary libraries:

  pip install Flask Flask-SQLAlchemy

Configure Flask application with MySQL database:

  from flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)

# Replace 'mysql://username:password@localhost/db_name' with your MySQL configuration
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://username:password@localhost/db_name'
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False  # Suppresses SQLAlchemy warning

db = SQLAlchemy(app)

Define a model:

  class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(50), unique=True, nullable=False)
    email = db.Column(db.String(100), unique=True, nullable=False)
    # Add more columns as needed

Create database tables:

  # Import the db instance from your application
from your_app_name import db

# Create tables

Try to answer about this code:

What library is commonly used to facilitate interactions between a Python Flask application and a MySQL database?



What is the purpose of the line app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False in the Flask application configuration?

Enables tracking of database changes
Disables Flask's modification tracking for SQLAlchemy

Automatically applies modifications to the database schema
Tracks modifications made by multiple users

Which step in the process involves defining the structure of database tables using SQLAlchemy in a Flask application?

Step 1: Install necessary libraries
Step 3: Define a model

Step 2: Configure Flask application with MySQL database
Step 4: Create database tables

What command or method in SQLAlchemy is used to create the actual tables in the MySQL database from the defined models?
