Comment:
Right, inner does not have a primary key value until you call save() on
it. So you cannot correctly specify it as the target of outer's key
before then. Your code should be:
{{{
#!python
inner = Inner(field="test")
inner.save()
outer = Outer(inner=inner, other_field="other test")
outer.save()
}}}
I'm pretty sure this is spelled out somewhere in the docs though I can't
find it at the moment. The fact that save() is what creates the object's
pk is noted here:
