this can happen if you are using the wrong datatype for your primary key. like
it's a string in the database and you are referring to it as an Integer, that
kind of thing.
no way to provide more detail without seeing a short version of the mapping
that produces this error and CREATE TABLE stat
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: UPDAT
