How do I use commit in Flask ORM?

In Flask ORM, you use the commit() method to save changes to the database. After making changes to your models, call db.session.commit().

Can you show me a code example?

Sure! Here's a simple example:

from yourapp import db, User

new_user = User(name='John Doe')
db.session.add(new_user)
db.session.commit()

What happens if I forget to call commit?

If you forget to call commit(), your changes won't be saved to the database, and you'll lose any modifications made during the session.

Is there a way to rollback if something goes wrong?

Yes! You can use db.session.rollback() to revert the session to the last commit if an error occurs.
