I am completely stumped after working on this issue for 2 days. I am simply querying a user, updating the name, and sending it back to the database.
user = session.query(User).get(1) user.first_name # John user.first_name = 'Sally' session.commit() # > sqlalchemy.orm.exc.StaleDataError: UPDATE statement on table 'user' expected to update 1 row(s); # -1 were matched. What is causing this error? -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
