When using the newly introduced query-expression ordering feature in
either the model's Meta.ordering or in its ModelAdmin causes errors.
Steps to reproduce:
First variant - using the model's Meta.ordering option -
{{{
//models.py
class Game(models.Model):
score = models.IntegerField(null=True)
class Meta:
ordering = [F("score").desc(nulls_last=True)]
...
// admin.py
admin.site.register(Game)
}}}
Accessing the admin site will now give an `AttributeError: 'OrderBy'
object has no attribute 'startswith'`
Variant 2 - Using the ModelAdmin ordering attribute:
{{{
//admin.py
class GameAdmin(models.ModelAdmin):
ordering = [F("score").desc(nulls_last=True)]
}}}
`runserver` fails with error: `TypeError: argument of type 'OrderBy' is
not iterable`
