Comment:
Hi Barry. Thanks for the report.
For me, this is just how things are expected to work, so I'm going to say
wontfix. I'm happy if you want to take it to the DevelopersMailingList for
a wider discussion, but (in general) I'm suspicious of a ''"simple
change"'' adjusting a long-standing behaviour like this… (Perhaps there's
a case to be made on the mailing list though.)
To address the example, my first thought is that you should be saving
`parent` before creating child:
{{{
parent = Parent(name='parent_object')
parent.save()
child = Child(parent=parent)
...
}}}
My second is that, you have `parent`, so print the name from there:
{{{
print(parent.name)
}}}
I appreciate you've no-doubt reduced this in order to show the issue more
clearly than in a real example, but I'd suspect those thoughts would go
back to the more realistic case.
However, as I say, the DevelopersMailingList is a better venue to pursue
this kind of thing.
Thanks.
