Hi all,
I had an arror in my code and i think i have reconstructed it as follows:
-----------------------------------------------------------------------------------------------
from sqlalchemy import Column, Integer, String
from sqlalchemy import create_engine
from sqlalchemy.orm import sessionmaker
from sqlalchemy.ext.declarative import declarative_base
Base = declarative_base()
engine = create_engine('sqlite:///:memory:', echo=True)
Session = sessionmaker(bind=engine)
class User(Base):
__tablename__ = 'users'
id = Column(Integer, primary_key=True)
name = Column(String)
Base.metadata.create_all(engine)
session = Session()
user = User(name = 'bob')
session.add(user)
session.commit()
#user.name
del user.name #error in sqlalchemy file attributes.py line 529
#user.name
session.commit()
assert user.name == None #error: user.name is still 'bob'
------------------------------------------------------------------------------------------------------------
These two errors do not occur if i access the attributes before the delete
or the commit (i.e. uncomment the #user.name lines).
I am using version 7.5; are these errors solved by the latest version?
I would like to avoid upgrading at this point, but if i could be
reasonably sure that upgrading solves the problem, then no problem ..
Cheers, Lars
