Description
I have a model whose primary key is not an AutoField, and another model with a foreign key pointing at that:
class Country(models.Model): id = models.CharField(max_length=2, primary_key=True) class Place(models.Model): country = models.ForeignKey(Country, models.CASCADE)
And a ModelAdmin with this list_filter:
@admin.register(models.Place) class PlaceAdmin(admin.ModelAdmin): list_filter = ["country"]
Since 45ecd9acca9b36093e274f47b6877a5f79108d9e, filtering places by country in the admin site raises django.contrib.admin.exceptions.DisallowedModelAdminLookup: Filtering by country__id__exact not allowed

Hi.
This seems to have broken django admin url filtering on foreign keys as well.
I have a model, PriceGroup with FK to Booking, and when i attempt to filter PriceGroup in django admin on ?booking_id=... in the url i get Error: Filtering by booking not allowed
in a small red alert box.
The foreign key being declared as
booking = models.ForeignKey(Booking, null=False, on_delete=models.PROTECT)
and booking having the default primary key that django makes.

Hi @aleksanb 👋
Yes, this has been raised here: https://code.djangoproject.com/ticket/35087
I can reproduce in latest Django main and I confirm that this is a regression in the reported revision 45ecd9acca9b36093e274f47b6877a5f79108d9e
