How do I manage sessions in Flask-SQLAlchemy?

In Flask-SQLAlchemy, you can manage sessions using the db.session object. You can add, commit, and rollback transactions.

Can you show me an example of adding a new record?

Sure! You can create a new instance of your model, add it to the session, and then commit it. For example:

new_record = MyModel(name='example')
db.session.add(new_record)
db.session.commit()

What if I want to rollback the session?

If you need to rollback, you can call db.session.rollback(). This will revert any changes made in the current session.

Is there a way to query records using the session?

Yes! You can query records using the session like this:

records = MyModel.query.all()
