flask mysql config

To configure Flask to work with MySQL, you first need to install the necessary packages. You can do this using pip by running the following command:

pip install flask-mysql

Once you have installed the package, you can then create a connection to your MySQL database using the following code:

from flask import Flask
from flaskext.mysql import MySQL

app = Flask(__name__)
mysql = MySQL()

# MySQL configurations
app.config['MYSQL_DATABASE_USER'] = 'your_username'
app.config['MYSQL_DATABASE_PASSWORD'] = 'your_password'
app.config['MYSQL_DATABASE_DB'] = 'your_database'
app.config['MYSQL_DATABASE_HOST'] = 'localhost'

mysql.init_app(app)

In this code, you should replace `your_username`, `your_password`, and `your_database` with your own MySQL database credentials. You can then use the `mysql` object to execute SQL queries on your database.

For example:

@app.route('/')
def index():
    cursor = mysql.get_db().cursor()
    cursor.execute('SELECT * FROM users')
    users = cursor.fetchall()
    return str(users)

This will execute a simple SQL query to select all the rows from the `users` table and return the result as a string.
