Is there any reason why this has to happen after saving? otherwise you
could use pre_save.

No, just if you use auto generated PKs. Exactly this is the point. We

this solution.
Checking 'InstanceModel.objects.exists(pk=self.pk)' generates too much

I get again to different results.
the shell accesses the settings.py while from the testserver the
settings.pyc is accessed. After I deleted the pyc-file. the testserver
uses the settings.py too.

As a side note, I think the getting started documentation should be
