How can I handle errors in Flask ORM?

In Flask ORM, you can handle errors using try-except blocks around your database operations. This allows you to catch exceptions and respond accordingly.

What types of errors should I be looking out for?

Common errors include IntegrityError for unique constraints, OperationalError for database connection issues, and DataError for invalid data types.

Can you show me a code example?

Sure! Here's a simple example:

from flask_sqlalchemy import SQLAlchemy, IntegrityError

db = SQLAlchemy()

try:
    new_user = User(username='example')
    db.session.add(new_user)
    db.session.commit()
except IntegrityError:
    db.session.rollback()
    print('Username already exists!')

What about logging these errors?

You can use Python's logging module to log errors. Just configure the logger and log the exception in the except block.
