Hi,
I started to play with events to port a library to sqla 0.7. I managed to
use
the 'listen' function but I failed on 'remove'. Looking at the signatures
they seem to be just the same, but here is what I get:
In [7]: event.listen(obj.__class__.title, 'set', listen_cb)
In [8]:
remove() isn't implemented yet.While the simple operation you see below
would be fine for a single listener on a single target, the targets we have
which propagate to subclasses (mapper events, attribute events) would require a
more elaborate system that can revisit everywhere the event has
