Comment:
Bisected to 4bc00defd0cf4de3baf90cad43da62e531987459. I think the warning
is correct as there is a `Region.organisation` accessor that your foreign
key is overriding. Using the models you provided but without with foreign
keys:
{{{
u = OrgUnit.objects.create()
o = Organisation.objects.create(orgunit_ptr=u)
r = Region.objects.create(orgunit_ptr=u)
r.organisation == o
}}}
I think the warning's wording must be corrected to something like "The
field 'organisation' clashes with the related accessor 'organisation' from
model 'org.orgunit'." but I'm not certain about this analysis. It might be
possible to continue to allow the overriding you've been doing -- I'm not
sure if a patch is feasible.
