Sending mapped instances over XMLRPC is basically nonsense. XMLRPC is designed for transporting elementary datatypes over the wire in order to invoke a remote method. It is not designed for sending instances of some class and not for sending Python pickles. No idea what you are trying to accomplish. Consider converting a mapped instance to dict and sending this dict serialized in JSON format to a remote XMLRPC server. - -aj -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAknB17UACgkQCJIWIbr9KYwARgCeJ1VuU6Gi9p+GVkYQzZiVWMd3 aJoAoMwJUc8lIyOBhDwJVq3/L3QzuRoK =aihX -----END PGP SIGNATURE----- --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
