implementing Flask-SQLAlchemy when handling database sessions in Python 3.11
After trying multiple solutions online, I still can't figure this out. I'm currently working with a question with session management in Flask-SQLAlchemy while using Python 3.11. I have a simple Flask application where I am trying to set up a SQLAlchemy database connection. However, I'm working with an `InternalServerError` whenever I attempt to commit a transaction after querying the database. Here's a snippet of my setup: ```python from flask import Flask, jsonify from flask_sqlalchemy import SQLAlchemy app = Flask(__name__) app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///example.db' db = SQLAlchemy(app) class User(db.Model): id = db.Column(db.Integer, primary_key=True) name = db.Column(db.String(80), nullable=False) @app.route('/add_user', methods=['POST']) def add_user(name): new_user = User(name=name) db.session.add(new_user) db.session.commit() # This line raises InternalServerError return jsonify({'message': 'User added'}), 201 ``` When I trigger the `/add_user` endpoint, I get an `InternalServerError`, and the logs indicate that it relates to the database session. I have tried wrapping the commit in a try-except block to catch exceptions, but it doesn't provide any additional useful information: ```python try: db.session.commit() except Exception as e: print(f'behavior: {e}') # Prints nothing helpful ``` I also made sure to initialize the database with `db.create_all()` before running the application. I suspect it might be a version-related scenario or perhaps I'm mishandling the session lifecycle. Has anyone else encountered this, or can you suggest a better way to manage sessions in Flask-SQLAlchemy with Python 3.11? I'm working on a application that needs to handle this.
