Description

I have two models.

class A(models.Model):
    pass


class B(models.Model):
    is_success = models.BooleanField(null=True)
    a = models.ForeignKey(A, on_delete=models.CASCADE)

And have defined admin for A class, with field is_success from B class, in that way:

class AAdmin(admin.ModelAdmin):
    list_display = ("is_success", )


    @admin.display(boolean=True, ordering="is_success")
    def is_success(self, obj):
        newest_b = obj.b_set.first()
        if newest_b:
            return newest_b.is_success
        else:
            return

When I tried to order by column is_success, Django admin raises an exception:

FieldError at /admin/test_bug_ordering/a/

However, I discovered a strange behavior. I can add a SimpleFilter like this:

class IsSuccessFilter(admin.SimpleListFilter):
    title = "Is Success Filter"
    parameter_name = "is_success"

    def lookups(self, request, model_admin):
        return [
            ("true", _("Yes")),
            ("false", _("No")),
            ("none", _("None")),
        ]

    def queryset(self, request, queryset):
        subquery = (
            B.objects.filter(a_id=OuterRef("id"))
            .values("is_success")[:1]
        )
        queryset = queryset.annotate(is_success=Subquery(subquery))
        if self.value() == "true":
            return queryset.filter(is_success=True)
        elif self.value() == "false":
            return queryset.filter(is_success=False)
        elif self.value() == "none":
            return queryset.exclude(is_success__isnull=True)
        else:
            return queryset


class AAdmin(admin.ModelAdmin):
    list_display = ("is_success", )
    list_filter = (IsSuccessFilter, )


    @admin.display(boolean=True, ordering="is_success")
    def is_success(self, obj):
        newest_b = obj.b_set.first()
        if newest_b:
            return newest_b.is_success
        else:
            return

And now I can order by is_success until I turn on facets option. When I click Show counts the exception occurs again, but without Show counts ordering works correctly.

Resolution:	→ invalid
Status:	new → closed

When I tried to order by column is_success, Django admin raises an exception:

This is an expected behavior, you cannot set ordering by nonexistent fields.

However, I discovered a strange behavior. I can add a SimpleFilter like this:

You added is_success annotation to the queryset so now you can order by it.

And now I can order by is_success until I turn on facets option. When I click Show counts the exception occurs again, but without Show counts ordering works correctly.

This is probably a duplicate of #35198.

Marking as "invalid" as it seems that you're experimenting with Django admin. If you're having trouble understanding how Django works, see TicketClosingReasons/UseSupportChannels for ways to get help.
