Thanks Anthony but what does it mean the proper signature?
def add_phplist_user(f,id):
auth_user = db.auth_user(id)
#add user
db_phplist.phplist_user_user.insert(
email = auth_user.email,
confirmed = auth_user.newsletter)
db.auth_user._after_insert.append(lambda f,id: add_phplist_user(f,id))
I have to take the new record data from somewhere, and if I do that:
db.auth_user._after_insert.append(add_phplist_user(f,id))
Of course f and id are not defined.
