Flask-mysqldb数据库游标

Question

I have a Python web server configured using Flask and a database using flask-mysqldb. Currently, I have the database connection at the start of the application, something like this:

from flask_mysqldb import MySQL

app = Flask(__name__)
mysql = MySQL(app)

And each route has its own cursor in this way:

@app.route('/action')
def execute_action():
    cursor = mysql.connection.cursor()
    # processing
    cursor.connection.close()
@app.route('/load')
def load_data():
    cursor = mysql.connection.cursor()
    # processing
    cursor.connection.close()

However, now I need to access that same database connection from within other classes and functions, but passing the connection as a parameter is not an option. Is there anyway I can declare that global and access it from other classes? either "app" or "mysql". Or a better way of doing this?

Apologies if it is too basic, I am relatively new using Python and Flask

Answer 1

The connection already is global. Accessing mysql.connection within the same request will yield the same connection , no matter where you access it from.
