Nope, I don't think so. I'm pretty sure p.children could be loaded with any strategy at all (eager, lazy, whatever) and the inverse=True thing wouldn't affect that at all. The only difference is that adding or removing items to/from p.children would have no affect on what children were actually related to p. > > im not sure whats accomplished by having the backref not "update both > sides"....why not just not specify the backref at all in that case ? > this would be possible though, the backref does consist of not just the > attribute bi-directional behavior, but also a hint used during a flush() > that its a bi-directional relationship. Well right, and that's what I ended up doing. But I sort of think the p.children collection will still try to update the relationship if it gets modified, which would cause problems in my case. That's why we might need to implement inverse=True. I'll play with it for a while and look into implementing it if there's a problem. > >> Wow, don't burn yourself out.
