Hi all,
I have the following mapping:
class SharesUsers(DeclarativeBase):
__tablename__='m2m_shares_users'
id=Column(Integer,autoincrement=True,primary_key=True)
user_id=Column(Integer,ForeignKey
('samba_users.id',onupdate="CASCADE",ondelete="CASCADE"),nullable=False)
share_id=Column(Integer,ForeignKey
('samba_shares.id',onupdate="CASCADE",ondelete="CASCADE"),nullable=False)
access_type=Column(SmallInteger,default=0,nullable=False)
user = relation(SambaUsers, backref=backref
('share_users'),lazy=False,passive_deletes=True)
share = relation(SambaShares, backref=backref
('users_shares'),lazy=False,passive_deletes=True)
when I delete a share object in the table m2m_share_users the
corresponding key is set to null and not deleted, I have on delete
cascade in my database definition,
how can I do a delete cascade without load related objects in memory
and without perform an update?
regards
drakkan
