Flask-SQLalchemy update a row’s information

by

Retrieve an object using the tutorial shown in the Flask-SQLAlchemy documentation. Once you have the entity that you want to change, change the entity itself. Then, db.session.commit().

For example:

admin = User.query.filter_by(username="admin").first()
admin.email="[email protected]"
db.session.commit()

user = User.query.get(5)
user.name="New Name"
db.session.commit()

Flask-SQLAlchemy is based on SQLAlchemy, so be sure to check out the SQLAlchemy Docs as well.
