My use case is this:
I have a model with two Managers - one named objects (the default), and
another one. I want the admin to use the non-default one (in my case I
can't even give it the default one since it doesn't return instances of
the model, but of another model it inherits from). So my solution (It
doesn't even merit a patch - its just 3 lines changed in
django/contrib/admin/options.py):
# my code
from django.contrib import admin
class MyAdmin(admin.ModelAdmin):
model = MyModel
manager = MyModel.othermanager
# unified diff against django/contrib/admin/options.py svn 8851
