#8682: Admin ordering works incorrectly if ModelAdmin.ordering has several
fields,
and one of them is an another Model field

If I create two dependent models, and ask the admin interface to order
instances of the dependent Model based on the field of the base Model AND
on its own field, the secondary ordering is lost. See minimalistic
example:
{{{
#!python
class Foo(models.Model):
is_active = models.BooleanField(default=True)
class Bar(models.Model):
foo = models.OneToOneField(Foo, primary_key=True)
name = models.CharField(max_length=100)
def __unicode__(self):
return "%s, %s" % (self.name, "active" if
self.foo.is_active else "inactive")
# ...
class BarAdmin(admin.ModelAdmin):
list_display = ('name',)
ordering = ('-foo__is_active', 'name')
admin.site.register(Bar, BarAdmin)
}}}
{{{
insert into app_foo set is_active=1;
insert into app_foo set is_active=1;
insert into app_foo set is_active=1;
insert into app_bar values (1,'aaaa');
insert into app_bar values (1,'ccc');
insert into app_bar values (1,'bbb');
}}}
If we run a manual query, it works as expected:
{{{
>>> Bar.objects.order_by('-foo__is_active', 'name')
[<Bar: aaaa, active>, <Bar: bbb, active>, <Bar: ccc, active>]
}}}
However, the admin page at http://my.site/admin/app/bar/ would display:
{{{
aaa
ccc
bbb
}}}
which means the ordering was lost.
If both fields are in the same model, everything works fine.
