Hi,
I've got a joined inheritance :
class Task(Base):
__tablename__ = 'task'
id = Column(Integer, primary_key=True)
class Invoice(Task):
__tablename__ = 'invoice'
id = Column(ForeignKey("task.id"))
When I delete an invoice, the associated task is also deleted, that's ok.
I've got a model TaskStatus related to the Task object and I'd like all
related status to be deleted when I delete an invoice:
class TaskStatus(Base):
__tablename__ = 'task_status'
id = Column(Integer, primary_key=True)
task_id = Column(ForeignKey("task.id"))
task = relationship("Task", backref=backref("statuses", cascade="all,
delete-orphan"))
How could I achieve that one ?
Regards,
Gaston
