Suppose you define a view like this:
{{{
from django.views.generic import DetailView
from django.contrib.auth.models import User
class UserDetail(DetailView):
model = User
queryset = User.objects.defer('password')
}}}
If you try to use the view, the default template name is
{{{auth/user_deferred_password_detail.html}}} instead of
{{{auth/user_detail.html}}}.
This is because Django creates a proxy model each time you use defer/only.
And therefore {{{User.objects.defer('password')[0]._meta.model_name}}} is
{{{'user_deferred_password'}}}.
{{{(DetailView|ListView).get_template_name}}} should ckeck if
{{{model._deferred}}} and use {{{model._meta.proxy_for_model}}} to get the
original model.
