Hi, I have declarative Model with couple of columns, one of them is
lastAccess = Column('LastAccess', DateTime, nullable=False, onupdate=datetime.datetime.utcnow) I fetch the object from database like the following: obj = ScopedSession.query(Model).get(something) Later in code I commit the session as: ScopedSession.commit() I would like to have *lastAccess* updated in database when issuing *commit()*. However the column remains unchanged. I do understand that *onupdate* callback is called on update, but how to trigger the update since I don't want to change any other column? In other words, how can I mark the *obj* as "dirty" so *onupdate* will take effect? -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
