Hi,
I have a before flush event set up that sets the current user_id and
datetime on new objects that are going to be commited to the database
(all tables have these fields).
Unfortunately, it seems to ignore changes I make to existing objects, ie
when I set the user_id (which i get from pyramid) and last_updated
columns in the event handler, the sql only issues updates for the other
columns that where modified.
Any ideas as to what am I missing?
Thanks in advance,
Damian
def attach_user_committing(Session, flush_context, instances):
"""This function gets called by the before_flush event,
it grabs the current threads request and extracts the
authenticated user_id out of it. You can only
commit things if you are authenticated.
Once it has that id, it goes through and adds the id
of the user who modified it to new commits- need to be careful that
_new doesn't change.
"""
#this is used when creating databases & testing only
user_id = 1
if not creating_database:
user_id =
authenticated_userid(pyramid.threadlocal.get_current_request())
#for each object being committed/flushed, set the
flushing/commiting user
for obj in Session._new.values():
#log.debug(obj)
obj.user_id = user_id
obj.last_updated = datetime.now()
log.debug('Session dirty is : %s' %Session.dirty)
for obj in Session.dirty:
log.debug('Objects in dirty: %s' % obj.__dict__)
#if obj._sa_instance_state.modified:
obj.user_id = user_id
obj.last_updated = datetime.now()
#session.user_id = request
#this event ensures that user_id & lastupdate is correctly stored on
each commit.
event.listen(Session, "before_flush", attach_user_committing)
