I was not aware of the reload method! Thank you for pointing this out. So this would be pfrom.reload.destroy > Also, > maybe it would be enough to set the "dead" parent's children array to > []. Interesting idea. I think, 'reload' is nicer, because it is more likely that this part of the interface won't change when a new version of Rails is coming. Changing the children-array looks a bit like a hack to me (we need to know that they are stored in an array). But still I'm curious: How do I explicitly manipulate the childrens array? I didn't find a suitable method in the Active Record docs, and I don't expect that something like pfrom.children=[] would do it.
