Hi all,
I have a situation where I want to declare a relation between two
tables, but I want to be able to run a callback whenever I append to
that relation. Here's an example
class Kennel:
def callback(self, o):
print "callback", o
mapper = Mapper(
Kennel,
kennelTable,
properties = {
"dogs" : relation(
Dog, cascade="all, delete-orphan"
),
}
)
So whenever I use mykennel.dogs.append(fred) I want to be able to tell
the relation to call callback() so that I can do some checking on the
object that is being appended.
Is this possible ??
Cheers
Dave
