my code is still running on sqlalchemy .48, so if this has been
addressed in future versions - let me know!
lets say i have a one-to-many sqlalchemy relation, and loop an
attribute called items:
def cleanup( cart ):
for item in cart.items:
if item.qty == 0 :
self.dbSession('write').delete( item )
once i call cleanup(cart) , how can i ensure that looping through
cart.items will not bring up the deleted items ?
if i loop through the cart.items again, I'll have None types where I
deleted
i found that if i do a flush() and expire() , i can avoid this
for item in cart.items:
...
self.dbSession('write').flush()
self.dbSession('write').expire(cart)
Is this the best way to handle the situation ? is there something
better ?
