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 db.create_all()
Try to answer about this code:
What library is commonly used to facilitate interactions between a Python Flask application and a MySQL database?
Flask-MySQL
Flask-SQLAlchemy
Flask-Database
SQLAlchemy-MySQL
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?
db.connect_all()
db.create_all()
db.make_tables()
db.init_tables()
