yea a backref is essentially this:
mapper(Attivita, a_table, properties={
'specie':relation(Specie)
})
mapper(Specie, b_table, properties={
'attivita':relation(Attivita)
})
so without the backref you have one less "relation" set up.
but i have bad news for you, SA should be managing that relationship
in the way you dont like for both of those relations. im not sure
why it isnt working, because even if you havent loaded the dependent
item into the session, the delete operation should be loading it in.
