Hi -
I'm wondering what the lines at the end of django/db/models/
deletion.py do:
for model, instances in self.data.iteritems():
for instance in instances:
setattr(instance, model._meta.pk.attname, None)
They're at the end of the delete method from Collector class,
https://code.djangoproject.com/browser/django/trunk/django/db/models/deletion.py#L277
They came in in the original version of this file in
https://code.djangoproject.com/changeset/14507 by carljm.
I just don't quite get why this is needed (and I'm working on a django
mod that is stopping declared immutable fields from being mutated --
sometimes throwing an exception) - I could make sure that it always
silently fails, but I'm wondering why it exists at all.
My guess would normally be something to do with freeing up garbage
collection or something similar, but I can't see that with something
that is 99% likely to be an integer.
kind regards
Tim
