#31481: Using model functions in model meta ordering fails in admin

-----------------------------------------+------------------------
Let's assume we have two models as follows:
{{{
from django.db import models
class ExampleObject(models.Model):
some_field = models.CharField(max_length=50)
class Meta:
ordering = [models.functions.Lower('some_field')]
class ExampleExtension(models.Model):
example_object = models.OneToOneField(
ExampleObject, primary_key=True, on_delete=models.PROTECT
)
}}}
If I register the latter model in admin:
{{{
from django.contrib import admin
from myapp import models
admin.site.register(models.ExampleExtension)
}}}
I get the following error:
{{{
FieldError at /admin/myapp/exampleextension/
Cannot resolve keyword 'some_field' into field. Choices are:
example_object, example_object_id
}}}
If I remove the `Lower` model function it works as expected. Also, the
ordering generally seems to work fine in all other places, except in the
admin interface. Am I doing something silly?
