I have a many-to-many relationship with attributes:
Parent - AssocObject - Child
I'm trying to set it up so that when an AssocObject is removed from parent,
that instance of AssocObject and the Child are also deleted. So in my view I
do:
del parent.associatedobjects
I have changed the model so that the definition of Parent includes
associatedobjects = relationship("AssocObject", cascade = "delete,
delete-orphan")
This seems to work, however when I then try to add a new AssocObject:
parent.associatedobjects[0] = AssocObject()
I get a warning:
Object of type <AssocObject> not in session, add operation along
'Parent.associatedobjects' will not proceed
What am I doing wrong?
Thanks,
Ben
